铣刀杆系列MILLING CUTTERS

特点：

立铣刀和端面铣刀优点:

◎材料：42CrMo；

◎硬度：40-43HRC;

◎整体预硬化，然后再精细加工，提高加工精度。

◎检查刀片和铣刀本体之间的间隙用塞尺小于0.02，刀片用完在轴向和径向方向≤0.03时，降低表面粗糙度和延长工具的寿命。

◎深冷处理：所有CNC铣刀和面铣刀超长冷处理（-180℃以上超过20小时）使残余奥氏体转变为马氏体和纳米尺寸的碳化物颗粒的沉淀，提高工具，硬度，韧性，耐久性，并减少残余内应力。

Features:

◎Material: 42CrMo;

◎Haedness: 40-43HRC;

◎Overall pre-harden first,then fine processing,avoid transformation when proceed twice;◎Inspect the gap between insert and milling body with feeler gauge less than 0.02,blade run out at axial and radial direction≤0.03,reduce the surface roughness and prolong tool's life.

◎Sub-zero treatment All of the CNC end mills and face mills are processed long time sub-zero treatment(-180℃，more than 20 hours)Make the residual austenite into martensite and precipitate of nano-sized carbide particles,enhance tools' hardness, toughness, durability,and reduce the residual internal stress.

◎Thermal aging treatment Long time thermal aging treatment can get rid of the residual internal stress in grinding process.
