In order to obtain a better cutting surface and extend tool life, be sure to use a toolholder clamp with good precision, high rigidity, and good dynamic balance.
1. Before using this tool, please measure the tool deflection. If the tool deflection accuracy exceeds 0.01MM, please correct it before cutting.
2. The shorter the length of the tool protruding from the chuck, the better. If the tool protrudes longer, please lower the rotation speed, feed speed or cutting amount.
3. If abnormal vibration or sound occurs during cutting, please reduce the spindle speed and cutting amount until the situation improves.
4. Spray or air jet is the best way to cool steel materials, so that high-aluminum titanium can exert the best effect. It is recommended to use water-insoluble cutting fluid for stainless steel, titanium alloy or heat-resistant alloy.
5. The cutting method is affected by the workpiece, machine, and software. The above data are for reference only. After the cutting condition is stable, increase the feed speed by 30% to 50%.
