Stainless steel drilling is easy to wear, which is a common problem in hardware manufacturing, the machinability of stainless steel materials is much worse than that of ordinary carbon steel, and whether it is turning or milling or drilling, the stainless steel products, if the tool is not chosen more or less will be easy to wear. In addition, stainless steel toughness is high and easy to stick, so the drill hardness is also high. Therefore, the drilling of stainless steel materials is more difficult.
1. Due to the large plasticity and high toughness of stainless steel, the bit adhesion and wear during drilling are large. Stainless steel has low thermal conductivity and poor thermal conductivity, and the drill bit is surrounded by the wall of the hole, and the heat dissipation is not easy. Because the geometric Angle of the bit is not reasonable, it is easy to wear the bit. Low durability.
2. The cutting is discharged in a ribbon, which is easy to hurt and worsen the drilling conditions, so that the coolant is not easy to inject or is not injected at the blade. Therefore, it is necessary to study and improve the geometric parameters of the standard drill bit, select the appropriate and reasonable cutting parameters, in order to reduce wear, improve the durability of the drill bit, and ensure the smooth chip breaking and chip removal.
