Products advantages
1. The unique design of nut: high speed cutting, reduce drag and cutting noise and improve work efficiency,Balance for G2.5 30000rpm. G6.3 12000rpm.
2. General purpose high speed, high precision machining, cutting effect is good.
3. special coating surface treatment,improve the hardness and endurance of the surface,cleaness better,accuracy stable,surface
4. higher system accuracy.
5. High hardness, toughness and wear resisance, High thermo stability and high heat resistance
 
Reminder [tool]
In order to get the better of the cutting surface and extend the life of cutter. Be sure to use the high precision, high rigidity, dynamic balance better handle.
1. the use of the tool, please test tool deflection, the tool deflection accuracy than 0.01MM, please correct it before cutting.
2. The tool chuck out length as short as possible, tool overhang if extended longer, please cut speed, feed rate and cutting amount.
3. in the cutting vibration or sound if abnormal, please cut the spindle speed and cutting amount to the situation has improved.
4. steel cooling with spray or jet is the best suitable way, in order to make the best of high aluminum and titanium. Stainless steel, titanium alloy or alloy to recommend the use of non water soluble cutting fluid.
5. according to the workpiece, cutting machine, software, the above data are for reference only, to be in stable condition after the cutting feed speed to increase 30%~50%.
