How To Prevent The Ultra Thin Saw Blade From Cracking
Apr 17, 2021
Many customers may break or trampoline when using ultra-thin saw blade milling cutter. If it is a phenomenon of trampoling, it may be solved. Send it directly to the manufacturer producing saw blade milling cutter for grinding and maybe re open the teeth. However, it is true that the saw blade milling cutter is scrapped. This saw blade milling cutter is good for high-speed steel and the loss is smaller. It's tungsten steel that's miserable. So today we share with us what should be noted in the application of ultra-thin saw cutter, so that you can reduce the loss as much as possible.
The thinner the saw cutter, the more sensitive it is to the vibration and tensile stress when it is used. If there is radial or axial runout, it is easy to cause damage. Therefore, the milling machine should be operated in a better state, namely, the machine tool has high precision, good rigidity of cutter rod, stable transmission, constant feed quantity per tooth, abundant cooling, detailed requirements are as follows:
1. the accuracy of milling cutter installation on the cutter rod shall generally meet the following requirements: radial jump is less than or equal to 0.02mm, and axial jump is less than or equal to 0.01mm
2. only the cutting depth of milling cutter is not affected, and the two sides of the blade are clamped on the cutter rod with large flange as far as possible, so as to eliminate the vibration and prevent lateral pressure. Generally, the diameter of flange plate is not less than one third of the outer diameter of the saw blade milling cutter.
3. reasonable milling line speed VC and feed amount SZ of each tooth shall be selected. Generally, under the same conditions, the whole carbide saw blade milling cutter (tungsten steel) can be selected faster than that of high-speed steel saw blade milling cutter, but the feed quantity of each tooth shall be lower than that of high-speed steel. SZ can be generally between 0.005-0.25mm teeth. The detailed parameters shall be based on the speed of milling machine and the nature of the milling material, The selection of milling material properties, milling cutter outer diameter, thickness, tooth number, milling depth and other factors.
