How long is the tool life on the Citizen L20E-2M8 walker?

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 a 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 per minute reaches more than 200 meters, tool wear will be significantly accelerated, may originally be able to process 1000 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.
