How can I reduce tool wear on my Citizen L20E-2M8 centering machine?

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 tools
According 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 tool life by 2-3 times.
2、Optimize cutting parameters
Control 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.
Adjustment of feed: under the premise of ensuring processing efficiency and quality, try to use a smaller feed. Smaller feed can reduce the amount of cutting per revolution of the tool, 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 process
Adequate 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.
