Product parameters

• Product Name : HRC55 Ball-Nose End Mill

• HRC : 55

• Number of blades ： 2 flutes

• Coating : TiSiN (  Containing silica，very high surface hardness and high thermal resistance  )

• Tolerance of End Mill Diameter :

          1＜D≤6       -0.010~-0.030

          6＜D≤10      -0.015~-0.040

          10＜D≤20     -0.020~-0.050

• Cutting Parameters ：

          Cutting Speed        vc = 130（120-180）m/min

          Cutting Depth        ap = 1/3D(1/8-1/2D）

          Single Edge Feed    fz = 0.15mm(0.02-0.2)

         ★ Please adjust the parameters accroding to the material and hardness of workpieces.

• Helix angle ： 30° (Chip removal  of spiral / Smooth chip removal)

• Milling method : Face Milling /   Side Milling

• Double-edged belt：reduced product burr and non-stick milling tools

•  Edge :  

           Fully polished milling cutter edge.

           Degign of cutting edge over center

          Cutting edge passivation,burr-free cutting.

           Processed by German WALTER machine.  

• Material : Tungsten Steel Raw Materials

• Chamfer : Enhanced vibration resistance and cutting speed of milling cutters. Easy to operate.

• Processed workpiece material :Cast Iron , ( Alloy Steel , Carbon Steel , Hardened Steel )≤HRC55 Steel

  ★ Attention：Not suitable for machining aluminum alloys and plastic parts

• Equipment : Engraving Machine / CNC Machine

  ★ High-speed milling equipment is not applicable to hand drill, key machine and other equipment.

• Before using the tool，please measure the accuracy tolerance of the tool，if the tool accuracy exceeds 0.01mm，please correct it before cutting.

• The shorter the tool protrudes from the collect,the better.If the tool protrudes longer,it is necessary to reduce the speed,feed rate or cutting volume。

• If producing abnormal vibration or sound during cutting,reducing the speed and cutting amount until the situation improves.

• The best way to the steel cooling is spray jet and air jet,which can improve the use of milling cutters.
