How to choose end mill to improve the efficiency of mold processing

In general, we will select the end mill from the following three points:
1. Select the type of CNC tool coating according to the type and hardness of the machined workpiece. For the processing of workpieces with hardness below HRC55 such as carbon steel, the TIALN coating of KHC tungsten steel milling cutter is optional. When processing workpieces with quenching and heat-treating materials up to about 60 HRC, ALTIN ​​Coatings are available. In the processing of workpieces with higher hardness, the tool shape, carbide material and coating can be selected for high hardness processing TISIN coating for high hardness HRC65 materials.
2. Select the shape of the end mill neck according to the shape of the machined workpiece. The neck shape of the ball end mill is divided into standard type, long neck type and long edge type, and extended shank type, which can be chosen according to the processing depth and shape of the workpiece. Long neck type (deep groove milling cutter) can be used for deep digging, and the angle of interference should be considered when selecting. At the same time, compared with the long neck type, the stretched edge type end mill has high rigidity, which can improve cutting conditions and achieve better machining accuracy.
3. Select end mills with unique ball head precision according to machining accuracy. Ball end mills typically have a circular arc accuracy of 10 μm, but there are also 5 μm high-precision end mills that can be used for high-precision machining.

  • Use of new ultra-fine fine tungsten steel bar grinding, high rigidity and toughness.
  • Wide application:High efficiency maching can be achived ranging from common copper maching.
  • Optimized structure:Approiate cominbation of sharp cutting edge and tool strength makes cutting easier and faster,extending tool life.
  • Versatile product series:Suitable for rough maching with high metal removal rate to finish maching with high surface quality.
  • Complete diameter range:Minium diameter of 0.25mm for maching of the smallest parts.
  • Use of excellent new blade shape, the surface is smooth, not easy to collapse, to enhance the rigidity of the tool, taking into account the rigidity of the tool and chip removal performance, making the cutting tool and chip more stable.
  • Round handle, chamfering, easy to use, increase the stability of the performance.
  • Tough and wear-resistant.
  • High strength and hardness.
  • Durable in use.
