HSC manufacturing process
HSC (High Speed Cutting) is a further development of conventional CNC milling. HSC is used when high cutting performance and high surface quality are required.
The HSC manufacturing process works at extremely high speeds - up to 100,000 spindle revolutions per minute. Compared to conventional machining, the feed rates are five to ten times higher. The chip thickness is significantly lower.


Advantages of HSC milling
- shorter processing times enable significantly reduced throughput times
- significantly lower cutting forces
- significantly lower component temperatures
- reduced cutting edge load
- improved chip and heat removal
- reduced heat distortion
- possibility of machining very thin-walled workpieces
- possibility of machining very hard materials (up to approx. 70 HRC) and special materials such as titanium and fiber-reinforced plastics
- HSC milling enables the best surface qualities thanks to soft, tangential tool paths
- post-processing of components is often no longer necessary
Range of applications for high-speed cutting
Today, high-speed cutting is no longer only suitable for special tasks. The range of applications is growing continuously.
HSC enables more economical and at the same time high-precision machining of workpieces. What is required for optimum results? Specific know-how, CNC machines specially designed for HSC milling and tools tailored to HSC milling.

Features of high-speed cutting
HSC milling is the ideal solution for demanding components with complex shapes. HSC technology is characterized by a very high tool speed and feed rates. These are considerably higher than with normal milling. The metal removal rate can therefore be significantly optimized..
Cutting data and accuracies
The HSC milling process offers exceptionally good cutting performance. Machining processes are carried out with up to 30 times greater metal removal rates. Feed rates are 5-10 times higher. Cutting forces are up to 30 times lower. The hardest materials are possible with accuracies in the tolerance range of up to ±1 μm.
Surface quality & degree of hardness
HSC milling enables accuracies in the tolerance range of up to ±1 μm and a surface roughness of Ra = 0.01 µm. Depending on the material, cutting speeds between 1000 and 7000 m/min are possible. Extremely hard materials up to approx. 70 HRC can be milled.
HSC milling tools
HSC milling tools have special tool geometries and high-end coatings. The cutting materials used are generally milling tools made of fine-grained carbide grades or CBN and PCD cutting materials.
No coolant necessary
High Speed Cutting does not require any cooling lubricants. The cutting speeds during HSC milling are higher than the thermal conductivity of the material. The heat generated during the cutting process can therefore not flow back into the workpiece.
