The following are some of the factors that affect the price of Sodick EDM: First, the equipment model and configuration        Different models of Sodick EDM in the performance, processing accuracy, cutting speed and other aspects of the difference, such as high-end EXC oil cutter price is relatively high, while the AQ water cutter price is relatively low. In addition, the configuration of the equipment will also affect the price, such as whether equipped with automatic threading device, high-precision control system, etc., the higher the configuration, the more expensive. Second, the degree of new and old equipment        The price of new Sodick EDM is usually higher, while the price of second-hand equipment will be due to the use of years, frequency of use, equipment colour and other factors significantly reduced, the use of short time, new colour of the second-hand equipment prices are relatively high. Third, processing accuracy and surface quality        The higher the precision and surface quality requirements of the Sodick EDM, the higher the price. For example, to achieve higher machining accuracy and better surface roughness of the model, often in the technical research and development, parts manufacturing precision and other aspects of more investment, the cost is also higher, the price is naturally more expensive. Fourth, cutting speed        Cutting speed of Sodick EDM prices are relatively high, because it usually means that the equipment uses more advanced technology and higher quality components to achieve efficient machining performance, thereby increasing the cost and price of the equipment. V. Brand and market positioning         As a well-known brand, Sodick's products have high recognition and brand value in the market, and the price is relatively stable and at a high level. In addition, for different market positioning and customer groups, Sodick will also launch different grades of products, the price of different grades of products will also be different. Sixth, after-sales service and technical support         Perfect after-sales service and strong technical support will increase the added value of the equipment, affecting its price. Sodick provides after-sales service, including equipment installation and commissioning, training, warranty period, maintenance response time, etc., high-quality after-sales service can make the user feel more at ease in the process of use, the corresponding price of the equipment will also be increased!

High cutting efficiency: the practical processing efficiency is 100-120mm²/min, and the large productivity can reach 350mm²/min.

The following are some ways to determine whether the WEDM needs maintenance: I. Machining accuracy Dimensional deviation: If the size of the processed workpiece is continuously out of tolerance compared to the design size, for example, when processing a batch of mold parts, the dimensional accuracy requirements for ± 0.01mm, but the actual machining of the parts out of the dimensional deviation exceeds this range, and can not be improved through the adjustment of the processing parameters, which may be the mechanical structure of the equipment, the control system or the discharge system has a problem, the Maintenance is required. Decline in shape accuracy: When the shape of the processed workpiece is obviously not in line with the requirements of the situation, such as cylindricity, flatness, straightness and other shape accuracy indicators deteriorate. For example, the cylindrical error of the processed cylindrical parts increases from the original 0.002mm to more than 0.01mm, or there are wavy undulations after the plane processing, which is likely to be caused by the wear of the guide rail, the precision of the screw decreases, uneven discharge, etc., and needs to be repaired. Surface roughness deterioration: under normal circumstances, slow walking wire processing can achieve a better surface roughness, such as Ra value below 0.8μm. If in the process of processing, the surface roughness deteriorates significantly, there are obvious surface lines, pockmarks, scratches, etc., and is not due to changes in the electrode wire, processing parameters or workpiece materials, it may be the discharge circuit, the working fluid system or mechanical transmission components failures, the need to check and repair the equipment. Second, electrode wire operation Automatic threading failure: If the success rate of automatic threading decreases significantly, for example, originally the success rate of automatic threading was above 95%, but now it often fails to thread the wire, or the threading time increases greatly, exceeding the normal range (such as from an average of 15 seconds to more than 1 minute), it may be that the mechanical parts of the automatic threading mechanism are worn out, the sensor malfunction, or electrical control system problems, which need to be repaired. Electrode wire tension abnormality: When the electrode wire tension is unstable and fluctuates significantly during processing, or the tension display value is out of the normal range, it will cause the electrode wire to jitter and affect the processing accuracy. This may be a failure of the motor, sensor, controller and other components of the tension control system, which needs to be repaired. Electrode wire breaks frequently: under normal processing parameters and material conditions, the electrode wire breaks frequently, such as the original number of wire breaks in a day not more than 2 - 3 times, and now breaks every few workpieces, which may be caused by the quality of the electrode wire, the discharge parameters are abnormal, the working fluid supply is insufficient or the chip removal is not smooth, and so on, and it is necessary to check and repair the relevant systems of the equipment. Third, mechanical movement Abnormal table movement: when the table in the process of moving obvious jamming, jittering, crawling phenomenon, or moving at an unstable speed, for example, in the setting of uniform speed movement, the speed appears to be fast and slow, this may be the guide rail wear, silk rod precision decline, motor failure or transmission components loose and other reasons, need to repair the mechanical movement system. Inaccurate positioning of the axes: equipment in the positioning operation, the axes can not accurately reach the set position, there is a large positioning error, more than the permissible range of equipment (such as positioning accuracy requirements for ± 0.005mm, but the actual error reaches more than 0.01mm), which may be a failure of the encoder, the transmission system error accumulation or control system positioning algorithm, the need for maintenance. Fourth, the control system Program execution error: If the equipment in the execution of the processing program errors, for example, can not correctly identify the program instructions, processing path deviation, can not be set in accordance with the parameters of processing and other situations, this may be a CNC system software failure, program transmission error or controller hardware failure, the need for control system inspection and repair. Frequent system alarms: the control system of the device frequently sends out alarm signals, and the alarm information shows that the hardware or software failures related to equipment, such as motor overload alarm, discharge abnormal alarm, high temperature alarm, etc., which indicates that there are problems with the device, you need to carry out the appropriate maintenance according to the alarm information. Fifth, the working fluid system Abnormal working fluid level: abnormal fluctuations in the working fluid level, such as level drop too fast, or level sensor failure leads to equipment can not correctly identify the height of the liquid level, which may be the working fluid tank leakage, pipe rupture, or level sensor damage and other reasons, need to be repaired. Working fluid temperature is too high: under normal processing conditions, the temperature of the working fluid is too high, exceeding the temperature range specified by the equipment (such as more than 60 ℃), which will affect the performance of the working fluid and machining quality, it may be the working fluid cooling system failure, such as damage to the cooling pump, radiator clogging, etc., need to be repaired. Serious contamination of the working fluid: the working fluid becomes turbid, has a strange odor, or it contains a lot of metal chips, impurities, etc., which will affect the insulating performance of the working fluid and chip removal effect, it may be the failure of the filtration system or a long time without the replacement of the working fluid caused by the working fluid system needs to be repaired or maintained. Sixth, the electrical system The equipment cannot start or stops suddenly: when the equipment cannot start normally after the start button is pressed, or stops suddenly in the process of machining and there is no obvious external reason (such as power outage), this may be caused by power supply failure, contactor failure, motor failure or control system failure, etc., and it is necessary to carry out a comprehensive inspection and maintenance of the electrical system. Abnormal heat or smoke of electrical components: In the process of equipment operation, found that some components in the electrical control cabinet (such as transformers, contactors, drives, etc.) appear abnormal heat, or even smoke, which indicates that these components may have been damaged or there is a short circuit and other faults, need to be immediately shut down and repair.

Evaluation of the performance and quality of used WEDM needs to be a comprehensive consideration from a number of aspects, the following are some specific methods: First, processing accuracy Direct measurement method: use professional gauges to measure the accuracy of the workpiece after processing of the slow-feeding wire equipment. For example, use calipers to measure the dimensional accuracy of the processed parts, including length, width, height and other dimensions, to see whether it is in line with the nominal machining accuracy range of the equipment. For shape accuracy, you can use a micrometer to measure cylindricity, flatness and other indicators. For example, machining a cylinder with a diameter of 10mm, its cylindricity deviation should be within the accuracy range specified by the equipment, such as ±0.005mm. Specimen processing assessment: through the processing of standard specimens to assess the accuracy of the equipment. For example, process a specimen with different shape features (e.g. square, round, skew, etc.) and observe its dimensional accuracy, shape accuracy and surface roughness. For high-precision slow-feeding equipment, the dimensional accuracy of the processed specimen can reach ±0.001mm, and the surface roughness Ra can reach below 0.8μm. Second, cutting speed Actual test: under the same processing conditions (such as using the same electrode wire, the same processing parameters, the same workpiece material, etc.), compare the cutting speed of the equipment. You can choose a standard size and thickness of the workpiece, such as a thickness of 50mm, side length of 200mm mold steel, record the time required for the equipment to cut the workpiece. A faster cutting machine will be able to complete the task in a shorter time, which is essential for improving productivity. Comparison of technical parameters: Check the machine's technical parameters manual for the range of nominal cutting speeds. However, it should be noted that the actual cutting speed may be affected by a variety of factors such as equipment aging, wear and processing conditions, so the technical parameters are only for reference. Electrode wire operation system Automatic threading function test: automatic threading operation is carried out several times to check the success rate and time required for threading. For the good performance of the slow-feeding equipment, the success rate of automatic threading should be more than 95%, and the threading time is shorter, generally about 10 - 30 seconds. Observe whether the threading process is smooth, there is no jamming, broken wire and other conditions. Electrode wire tension control check: check whether the electrode wire tension control system works normally. Stable tension is very important to ensure processing accuracy and surface quality. You can use the tension display device or tensiometer to check whether the tension of the electrode wire is within the specified range, and whether the tension can be kept stable during the processing. Fourth, the mechanical structure Appearance inspection: check the overall appearance of the equipment, check whether the body has obvious traces of collision, deformation, paint and other conditions. These surface damages may imply that the internal structure of the equipment also has problems, or has been subjected to improper use or transportation. Guide rail and screw inspection: Check the wear and tear of the machine's guide rails and screws. Minor wear may affect machining accuracy, while severe wear may cause the machine to move unevenly, lose accuracy or even fail to work properly. You can move the table manually to feel the smoothness of the movement, or use a tool such as a plug ruler to measure the gap between the guide rail and the silk rod. V. Control System Functional integrity test: check whether the functions of the CNC system are normal, such as program input and output, coordinate display, processing parameter settings, automatic compensation and other functions. Try to input different types of machining programs and observe whether the equipment can perform the operation correctly and can automatically compensate according to the set parameters during the machining process to ensure machining accuracy. System stability assessment: During the operation of the equipment, observe whether the CNC system will crash, report errors, program interruptions and other abnormalities. Stable control system is one of the key factors to ensure the stable operation of the equipment for a long time. Sixth, the working fluid system Cleanliness check: to see whether the working fluid tank internal clean, no impurities, sediments and oil. The cleanliness of the working fluid will directly affect the processing results and equipment life. If the working fluid tank is dirty, it may lead to contamination of the working fluid, which in turn affects the discharge performance of the electrode wire and machining accuracy. Working fluid circulation and filtration check: Check the working condition of the working fluid pump, including whether the pump pressure and flow rate are normal, and whether the filter is clogged. Problems with the working fluid pump and filter will affect the circulation and filtration effect of the working fluid, resulting in poor chip removal and high temperature in the processing area, thus affecting the processing quality. VII. Electrical system Electrical components check: open the electrical control cabinet of the equipment, check the appearance of the electrical components whether there are signs of burning, discoloration, corrosion, etc., which may indicate that the components are faulty or aging problems. At the same time, check whether the connection of the wire is firm, there is no damage, aging and so on. Insulation testing: Use an insulation resistance tester to check the electrical insulation of the equipment to ensure that there is no risk of leakage. Good insulation is one of the important conditions to ensure the safe operation of the equipment.

The following are some of the factors that will affect the price of the WEDM: First, the brand factor Brand awareness: like Fanuc, Shadick, Charmilles and other international brands, with its long-accumulated good reputation, advanced technology and quality product quality, has a high brand value in the market, the price of its equipment is often high. Brand market positioning: high-end brands usually focus on technological research and innovation, is committed to providing customers with high-precision, high-performance, high-stability WEDM to meet the high demand for processing quality and efficiency of the user needs, so the price positioning is also higher; while the low-end brands may be more focused on the price competition to attract the more price-sensitive, processing requirements of relatively low customer groups. Second, the technical parameters Processing accuracy: processing accuracy is one of the key indicators of the WEDM, the higher the accuracy of the equipment, such as the ability to achieve smaller dimensional tolerances and higher surface roughness requirements, its price is usually higher. For example, some used in aerospace, precision mold manufacturing and other areas of ultra-high-precision slow walking wire equipment, the price is often much higher than the ordinary precision equipment. Cutting speed: cutting speed of the WEDM can improve productivity and reduce processing costs, but this type of equipment is usually in the technical development, motor performance, control systems and other aspects of higher requirements, so the price will be raised accordingly. Third, the processing size range: equipment table size, stroke and the maximum size of the workpiece can be processed and other parameters determine the range of parts that can be processed. Processing size range of the larger the WEDM, the higher the price, because it requires a larger body structure, a stronger drive system and more stable control system to ensure processing accuracy and stability. Degree of automation: a high degree of automation of the WEDM, such as automatic threading, automatic unloading, automatic compensation and other functions, you can reduce manual intervention, improve productivity and processing quality, but also increase the manufacturing cost and price of the equipment. Four, equipment configuration Core component quality: the host of the WEDM, control systems, motors, guide rails, screws and other core components of the quality of the equipment directly affects the performance and service life. The use of high-quality imported parts or well-known brands of domestic parts, will increase the cost of equipment, the price will increase accordingly. Accessories: the equipment is equipped with accessories will also have an impact on the price, such as cooling system, chip removal system, electrode wire tension control system, filtration system and so on. Full-featured, high-performance accessories can improve the overall performance of the equipment and processing quality, but will also make the total price of the equipment increased. Fifth, the degree of new and old equipment Brand-new equipment: brand-new WEDM prices are relatively high, because it contains equipment development costs, manufacturing costs, sales costs and reasonable profit margins. At the same time, the new equipment also enjoys complete after-sales service and warranty period, which is also part of its price. Used equipment: the price of used WEDM is relatively low, its price is mainly affected by the equipment's service life, frequency of use, maintenance and equipment color and other factors. Use a shorter period of time, good maintenance, color newer used equipment prices will be relatively high, while the use of a longer period of time, equipment wear and tear of the used equipment prices will be lower. Sixth, the market supply and demand Market demand: when the market demand for WEDM, demand exceeds supply, manufacturers in order to obtain higher profits, will be appropriate to increase the price of equipment; Conversely, when the market demand is weak, supply exceeds demand, manufacturers in order to promote sales, will reduce prices to attract customers. Market Competition: The competitive market environment will prompt manufacturers to continuously improve product quality, reduce costs, and through the price strategy to compete for market share. In a fully competitive market, consumers have more choice, it is easier to find cost-effective equipment, which produces a certain inhibition of the price. Seven, after-sales service Service quality: quality after-sales service for the normal operation and long-term use of WEDM is critical. Provide perfect after-sales service, such as timely technical support, fast maintenance response, adequate supply of spare parts, etc., manufacturers need to invest a lot of manpower, material and financial resources, so after-sales service quality of the brand, the price of its equipment will be relatively high. Service content: different brands and manufacturers to provide after-sales service content may vary, some manufacturers may provide a longer warranty period, free training services, regular maintenance of equipment, etc., these additional services will also increase the value and price of the equipment.
