In order to effectively reduce the tool wear of WR L20E-2M8 centrifugal machine, you can start from the selection of tools, optimization of cutting parameters, improvement of machining process and maintenance of equipment, etc., the specific methods are as follows:1, reasonable selection of toolsAccording to the material selection tool: for different processing materials, select the appropriate tool material. Processing aluminum alloy and other non-ferrous metals, can choose diamond tool, which has a very high hardness and wear resistance, can achieve high efficiency processing; processing of stainless steel, titanium alloy and other difficult to process materials, it is appropriate to use cemented carbide cutting tools, which have good hardness, heat resistance and wear resistance.Consider the coating of the tool: choose a coated tool, such as TiN, TiC and other coated tools. The coating can form a protective film on the surface of the tool, improve the hardness, lubricity and oxidation resistance of the tool, reduce the friction and wear between the tool and the workpiece, which can prolong the life of the tool by 2-3 times.2、Optimize cutting parametersControl cutting speed: according to the processing material and tool characteristics, reasonable adjustment of cutting speed. Generally speaking, the processing of high hardness materials, cutting speed should be lower; processing of soft materials, cutting speed can be increased appropriately. Processing 45 # steel, for example, the use of carbide tools, cutting speed control in 100-150m/min is appropriate.Adjust the feed: under the premise of ensuring processing efficiency and quality, try to use a smaller feed. Smaller feed can reduce the cutting volume of the tool per revolution, reduce tool wear. For example, in milling, the feed can be controlled at 0.05-0.2mm/z.Determine the appropriate depth of cut: the depth of cut should be determined according to the size, shape and material of the workpiece. For harder materials or high precision requirements of processing, the depth of cut should be smaller; for soft materials or rough machining, the depth of cut can be increased appropriately, but to avoid excessive depth of cut to make the tool to withstand excessive load.3、Improve the machining processAdequate cooling lubrication: use good performance cutting fluid, and ensure that the cutting fluid is fully poured into the cutting area. Cutting fluid can play a role in cooling, lubrication, chip removal, reduce the cutting temperature, reduce the friction between the tool and the workpiece, chips. Such as processing stainless steel, the use of cutting fluid containing extreme pressure additives can effectively reduce tool wear.Adopt the appropriate processing sequence: rationalize the processing sequence, first roughing, remove most of the residual amount, and then finishing. Roughing, the tool to withstand a larger cutting force, you can choose a large feed, a larger depth of cut and lower cutting speed; finishing, in order to ensure the machining accuracy and surface quality, the use of smaller cutting parameters, so as to reduce tool wear in finishing.4, strengthen equipment maintenance and tool management= Maintain equipment accuracy =: Regular maintenance of the centrifugal machine, check and adjust the accuracy of the equipment to ensure that the spindle of the machine tool, guideway and other components are in good working condition. The maintenance of equipment precision can make the tool in the machining process to maintain a stable cutting state, reduce the vibration of the equipment, offset and other reasons for abnormal wear and tear of the tool.Timely sharpening and replacement of tools: establish a tool management system to record and monitor the use time and wear of tools. When the tool is worn, timely sharpening is carried out to restore the cutting performance of the tool. If the tool wear is serious and reaches the service life, it should be replaced in time to avoid excessive wear of the tool affecting the machining quality and efficiency and aggravating the damage of the tool.

The tool life of Citizen L20E-2M8 centering machine is not a fixed standard, and will be affected by a variety of factors, as follows:1, tool material    Carbide cutting tools: In general, if the processing of ordinary materials, such as easy to turn iron, etc., in the normal cutting parameters, after reasonable sharpening, carbide cutting tool life may reach the processing of thousands or even tens of thousands of products. But if the processing of higher hardness, toughness materials, such as titanium alloy, tool life may be shortened to processing hundreds of products.    High-speed steel cutting tools: Compared with carbide cutting tools, high-speed steel cutting tools are slightly worse in terms of hardness and wear resistance. Processing aluminum alloy and other softer materials, may be able to process two or three thousand products; processing hardness of 45 # steel and other materials, tool life may be in the processing of about one thousand products will need to sharpen or replace.2, cutting parameters    Cutting speed: cutting speed has a significant impact on tool life. Processing stainless steel, for example, if the cutting speed is too high, such as line speed of 200 meters per minute or more, tool wear will be significantly accelerated, may originally be able to process 1,000 pieces of product tool, can only be processed about 500 pieces.    Feed: feed is too large, the cutting force on the tool will increase. Such as in the drilling process, the feed from 0.1mm / r to 0.2mm / r, tool life may be reduced by 30% -50%.    Depth of cut: The increase in depth of cut will also increase the load on the tool. In milling, the depth of cut from 5mm to 10mm, the tool wear rate may be accelerated by about double.3, processing materials    Hardness: processing high hardness materials, such as quenched mold steel, tool wear fast, short life. While processing soft materials, such as pure aluminum, tool wear is relatively slow, long life.    Toughness: like titanium alloy such high toughness materials, in the cutting process will produce greater impact on the tool and friction, easy to make the tool wear and chipping, tool life is usually shorter.4, cooling and lubrication    Cutting fluid: the use of suitable cutting fluid can effectively reduce the cutting temperature, reduce friction. Such as in the processing of difficult-to-machine materials, the use of extreme pressure cutting fluid than not using cutting fluid, tool life can be extended by 20% -50%.    Cooling: the use of efficient cooling methods, such as internal cooling tool with external spray cooling, can better control the temperature of the tool to extend the life of the tool.
