Compared with the traditional processing methods, CNC machining on the tool requirements, especially in terms of rigidity and durability more stringent. Should be based on the machine's processing power, the workpiece material performance, processing procedures, cutting and other related factors, the correct choice of tool and shank. The general principle of tool selection is: not only requires high precision, high strength, good rigidity, high durability, but also requires dimensional stability, easy installation and adjustment. Rui Zheng Precision Tools Co., Ltd. remind buyers to meet the processing requirements under the premise, try to choose a shorter handle to enhance the rigidity of the tool.
Currently used metal cutting tool materials are mainly five categories: high-speed steel, cemented carbide, ceramics, cubic boron nitride, polycrystalline diamond.
1. According to CNC machining requirements of the tool, the general principle of selecting the tool material is to use as much as possible carbide cutting tools. As long as the processing allows the choice of carbide cutting tools, you do not have high-speed steel cutting tools.
2. Ceramic tool not only for processing a variety of cast iron and different steel, but also for processing non-ferrous metals and non-metallic materials. The use of ceramic blades, no matter what the situation should be used negative anterior horn, in order not to easily collapse, if necessary, the blade can be blunt. Ceramic cutting tools are ineffective in the following situations: short parts machining; intermittent cutting and heavy cutting with large impact; processing of simple substance materials such as beryllium, magnesium, aluminum and titanium and their alloys (easy to produce affinity, Peeling and chipping off).
3. Both diamond and cubic boron nitride are super-hard tool materials, they can be used to process any hardness of the workpiece material, with high cutting performance, high precision, low surface roughness. General available cutting fluid.
Polycrystalline diamond blades are generally used in the processing of non-ferrous and non-metallic materials.
Cubic boron nitride blades are generally suitable for chilled cast iron, alloy structural steel, tool steel, high speed steel, bearing steel with a hardness of more than 450 HBS and nickel base alloys, cobalt base alloys and high cobalt powder metallurgy parts with a hardness not less than 350 HBS.
4. From the structural application of the tool, CNC machining should be used as far as possible insert block machine indexable inserts to reduce tool wear after the replacement and pre-set time.
5. Use coated tools to improve wear resistance and durability.
