The normal service life of a coordinate grinder is affected by a variety of factors, generally speaking, its normal service life is about 10-20 years. The following are some of the factors affecting the service life of the coordinate grinder: First, the quality of equipment and brand Brand differences: well-known brands are usually in the design, manufacturing process, parts selection and other aspects of the more stringent and sophisticated, the overall quality and performance of the equipment is more guaranteed, the service life is relatively long. For example, Switzerland Hauser, the United States Moore and other internationally renowned brands of coordinate grinding machine, under normal use and maintenance conditions, often can be used for 15-20 years or even longer. Models and Configurations: The performance and durability of coordinate grinders vary with different models and configurations. High-end models are equipped with more advanced technology, better components and more optimized structural design, which can withstand greater workload and more frequent use, and the service life will be extended accordingly. Second, the use of the environment Temperature and humidity: the coordinate grinder should be installed in a relatively stable temperature and humidity environment, the ideal temperature is generally 20 ℃ ± 1 ℃, relative humidity is not higher than 70.5%. If the ambient temperature is too high or too low, and the humidity is too large, it will easily lead to the deformation of the equipment parts, corrosion and wear and tear, thus shortening the service life. Cleanliness: Dust, metal shavings and other impurities in the working environment, if they enter the interior of the coordinate grinder, will increase the wear and tear of the parts, affecting the normal operation of the equipment and the maintenance of precision, but also may lead to problems such as failure of the electrical system, reducing the service life of the equipment. Therefore, keeping the working environment clean is essential to prolonging the service life of a coordinate grinder. Foundation Stability: Coordinate grinding machines need to be installed on a solid, stable foundation with anti-vibration grooves and other measures to reduce the impact of external vibrations on the equipment. Otherwise, prolonged vibration may cause the precision of the equipment to drop and the connection between various components to loosen, thus affecting the service life. Third, maintenance Daily maintenance: Daily cleaning, lubrication, fastening and other maintenance work is to ensure the normal operation of the coordinate grinder and extend the service life of the basis. Regularly clean the debris and dust on the surface and inside of the equipment, replace the lubricating oil in time, check and tighten the connection screws of each part, etc., which can effectively reduce the wear and tear of the equipment and the incidence of failure. Regular calibration: The accuracy of the coordinate grinder is crucial to the processing quality, so it needs to be calibrated regularly. Through professional testing tools and methods, check and adjust the various precision indexes of the equipment to ensure that it always stays within the specified range, which not only improves the machining accuracy, but also avoids excessive wear and damage of the equipment due to the excessively poor precision, and prolongs the service life. Fault maintenance: timely detection and treatment of equipment failure in the operation process, to avoid the expansion of the fault, for the protection of equipment performance and extend the service life is also very critical. For some minor faults, if you can repair in time, generally will not have too much impact on the overall life of the equipment; but if the fault is ignored, it may lead to more serious damage, or even make the equipment scrap. Fourth, the frequency of use and load Frequency of use: the higher the frequency of use, the relatively faster the wear and tear of the equipment, the service life will be shortened accordingly. If a coordinate grinder works continuously for more than 8 hours a day, the wear and tear of its parts will be more serious than that of the equipment that works for 4 hours a day. Processing load: processing workpiece material hardness, size, processing accuracy requirements and other factors will also affect the service life of the coordinate grinder. If you often process high hardness, size or precision requirements of the workpiece, the equipment needs to withstand a greater cutting force and higher workload, which will accelerate the wear and tear of parts and reduce the service life of the equipment. Fifth, the quality of operators Professional skills: skilled grasp of the operating skills of the coordinate grinding machine and the process of the operator, can correctly use the equipment, to avoid damage to the equipment caused by improper operation. For example, when loading and unloading workpieces, they can do it gently, avoiding collision with the table and grinding wheel; when adjusting the processing parameters, they can set them reasonably according to the material of the workpieces and processing requirements, avoiding overloading of the equipment or processing quality problems caused by unreasonable parameters. Maintenance awareness: operators with a good sense of maintenance will pay attention to the operating status of the equipment in their daily work, timely detection and reporting of abnormalities in the equipment, and cooperate with the maintenance personnel to carry out maintenance and repair of equipment, thus helping to extend the service life of the equipment.

Here are some ways to assess whether the price of a used coordinate grinder is reasonable: First, the condition of the equipment itself Use of years: the use of years is an important factor affecting the price. Generally speaking, the shorter the use of time, the relatively less wear and tear of the equipment, the remaining service life is relatively long, the price will be relatively high. For example, a used coordinate grinder that has been in use for 2 years will usually cost more than a grinder of the same model that has been in use for 5 years. Wear and tear: Carefully check the wear and tear of the various parts of the machine, such as the table, guideway, wheel spindle, etc. If the wear is severe, it will affect the machining accuracy. If the wear is serious, it will affect the machining accuracy and performance of the equipment, the price is bound to decrease. For example, if the guide rail of the table has obvious scratches, uneven wear, etc., it means that the equipment is frequently used and poorly maintained, and its value will be greatly reduced. Accuracy Maintenance: The accuracy of a coordinate grinder is of paramount importance. Through professional testing tools and methods, check whether the positioning accuracy, repeat positioning accuracy and other indicators of the equipment are within a reasonable range. If the accuracy is super poor, the repair cost is high and the price should be reduced accordingly. For high-precision processing needs of users, the accuracy of the second-hand grinding machine does not meet the standard even if the price is low is not appropriate . Functional integrity: check whether the functions of the equipment are normal, such as the operation of the CNC system, the movement of the coordinate axes, the replacement and dressing of grinding wheels. If there is a lack of function or failure, the cost and time required to repair will affect its value, which in turn affects the judgment of the reasonable price. Second, the brand and model Brand influence: used coordinate grinding machines of well-known brands are usually more secure in terms of quality, performance and stability, high market acceptance, and relatively high prices. For example, the Swiss Hauser, the United States Moore and other brands, its technological content and advanced manufacturing process, product durability and reliability, the price in the second-hand market is often higher than the ordinary brand of similar products. Model differences: different models of coordinate grinding machine in the specifications, parameters, processing capacity and other aspects of the differences, thus affecting the price. Generally speaking, the price of large-sized, high-specification equipment is relatively high, but it is also necessary to combine with the actual needs to assess its reasonableness. For example, the Hauser S35-600 has a larger table and a larger grinding diameter than the S35-400, and the price is correspondingly higher. Third, the market situation Market supply and demand: when the supply of used coordinate grinders on the market is greater than the demand, the price tends to fall; conversely, if the supply exceeds the demand, the price will rise. Concerned about market dynamics, to understand the current market supply and demand for used coordinate grinding machines, help to determine whether the price is reasonable. For example, a certain period of time due to a large number of enterprises to upgrade their equipment and sell used coordinate grinding machines, resulting in an oversupply of the market, the price may be relatively low. Comparison of prices of similar equipment: By checking the second-hand equipment trading platform, professional dealers, auctions and other channels, to understand the recent transaction prices of the same brand, the same model, similar age and condition of the second-hand coordinate grinder, as a reference to assess whether the current price of the equipment is reasonable. However, it should be noted that different regions, under different trading conditions, the price may be different. Fourth, the technological upgrading CNC system version: the newer CNC system may be more advantageous in terms of functionality, ease of operation, machining accuracy control, etc. If the CNC system of the used coordinate grinder is not up-to-date, it may be more expensive. If the version of the CNC system of the second-hand coordinate grinder is too old, it may affect its processing efficiency and quality, which in turn affects the price. For example, the new CNC system has automatic compensation function, more friendly programming interface, etc., while the old system requires more manual intervention, the price of the equipment needs to be adjusted according to the actual situation of the CNC system. Technical innovation features: with the continuous development of technology, some new coordinate grinding machines may have unique technical innovation features, such as higher grinding speed, better cooling and lubrication system. In contrast, the lack of these features of the second-hand equipment should be reflected in the price. Five, other factors Transportation and installation and commissioning costs: when buying a used coordinate grinder, you need to consider the cost of transportation as well as installation and commissioning costs. If the location of the equipment is far away, the transportation costs are higher, or the equipment requires professionals to carry out complex installation and commissioning, these additional costs will affect the overall cost of the equipment and the judgment of a reasonable price. After-sales service and guarantee: ask the seller whether to provide after-sales service, such as warranty period, technical support and so on. Good after-sales service guarantee used coordinate grinding machine, the price may be slightly higher, but can reduce worries for the buyer. For example, some sellers provide one year warranty service, while some do not provide any after-sales service, the price should be different.

Selection of suitable used coordinate grinding machine, need to start from the following aspects: First, clear their own needs Processing accuracy requirements: according to the precision level of the parts to be processed, select the appropriate accuracy of the coordinate grinder. For example, if the processing of precision molds, you need to choose a high-precision second-hand coordinate grinder, the machining accuracy can be controlled at the micron level, such as ± 0.001mm - ± 0.005mm between, in order to ensure that the mold dimensional accuracy and surface quality. Processing size range: Measure the maximum size of the parts to be processed to ensure that the table size and stroke range of the used coordinate grinder can meet the processing requirements. Such as the processing of large automotive parts, you need to choose a larger table size, longer stroke of the coordinate grinding machine, table size is generally in the 600mm × 400mm or more, x / y / z-axis stroke in the 500mm × 300mm × 200mm or more. Production volume: If for mass production, should choose a high degree of automation, high productivity of the second-hand coordinate grinder, such as with automatic tool changer, automatic measurement system of CNC coordinate grinder, in order to improve production efficiency and product consistency; if for small batch production or single processing, the degree of automation requirements are relatively low, you can focus on the basic performance of the grinder and accuracy. Second, assess the condition of the equipment (a) Appearance inspection: check the overall appearance of the equipment, check whether there are obvious signs of damage such as collision, deformation, rust and corrosion. Whether the paint on the surface of the equipment is intact, if there is a large area of peeling, may suggest that the equipment has been in a poor working environment or a long service life. (ii) Key components inspection: Spindle: The spindle is the core component of the coordinate grinder, check its rotational accuracy, axial runout and radial runout. Measured with a percentage table and other professional tools, the general requirements of the spindle radial runout does not exceed 0.002mm - 0.005mm, axial runout does not exceed 0.001mm - 0.003mm. At the same time, check the spindle wear, such as spindle taper hole wear, journal wear, etc., if the wear is serious, it will affect the machining accuracy and stability. Guideway: Check the straightness, flatness and wear of the table guideway, grinding wheel holder guideway, etc.. The straightness of the guideway is generally required within 0.005mm/1000mm, flatness within 0.01mm/1000mm. If the guide rail wear is not uniform or obvious scratches, pits, will lead to uneven movement of the table, affecting the machining accuracy. Screw: Check the transmission accuracy, backlash and wear of the screw. Rotate the screw handwheel, feel whether the rotation of the screw is smooth, there is no stagnation phenomenon; with a percentage meter to measure the backlash of the screw, the general requirements of the backlash does not exceed 0.01mm - 0.02mm. If the screw is seriously worn, it will lead to a decline in the positioning accuracy of the worktable. (C) precision testing: if available, you can use professional testing tools to test the geometric accuracy and positioning accuracy of the coordinate grinding machine, such as laser interferometer, ballbar and so on. Testing items include the flatness, straightness and perpendicularity of the table, positioning accuracy of the coordinate axes, repeat positioning accuracy, etc., to ensure that the accuracy indexes meet the processing requirements, the general positioning accuracy should be within ± 0.005mm, repeat positioning accuracy within ± 0.002mm. (d) Wear degree assessment: by checking the use of equipment time, the number and types of workpieces processed, etc., to understand the degree of wear and tear of the equipment. Generally speaking, the use of a shorter period of time, the number of workpieces processed by a small number of second-hand coordinate grinding machine, the degree of wear is relatively light. Third, understand the history of the equipment Use records: Ask the seller about the use of the equipment, including the use of the industry, the type of workpiece processing, the average daily working time, etc., to understand the intensity of use of the equipment and the working environment. Maintenance records: check the maintenance records of the equipment, to understand whether the regular maintenance, replacement of wearing parts. If the equipment has a complete maintenance record, and maintenance work done well, its performance and accuracy is relatively more secure. Maintenance history: to understand whether the equipment has been a major failure, overhaul, etc.. If the equipment has been repaired or overhauled several times, you need to further understand the specific parts of the maintenance and the reasons, to assess the impact on the performance and accuracy of the equipment. Fourth, examine the performance of the equipment Control system: Check the control system of the coordinate grinding machine, to understand whether the operation interface is friendly, whether the function is complete, whether it has online measurement, error compensation and other functions. Currently on the market common numerical control system Siemens, Fanuc, etc., different numerical control system in the stability, precision control, programming convenience and other aspects of the difference. Grinding performance: focus on the grinding wheel speed range, grinding force, grinding efficiency and other indicators. The speed of the grinding wheel is generally between 10000rpm - 30000rpm, the higher the speed, the higher the grinding efficiency, but the higher the quality of the grinding wheel and balance requirements. At the same time, check the stability of the grinding process, whether there is vibration, noise and other abnormal phenomena. Degree of automation: According to the production demand, choose the used coordinate grinder with suitable degree of automation. High degree of automation grinding machine can reduce manual intervention, improve productivity and processing accuracy, but the price is relatively high. Such as automatic loading and unloading device, automatic measurement and compensation system and other functions, can be selected according to the actual situation. Fifth, consider the after-sales protection Technical support: ask the seller or the original manufacturer to provide technical support, including equipment installation and commissioning, operation training, troubleshooting and other services.
