For high-speed cutting
As the speed increases to a certain extent, the temperature and cutting force of the tool will gradually decrease. This phenomenon is used in high-speed milling technology.
High Speed Milling (HSM) and High Performance Milling (HPM) machining concepts
Example: roughing hardened steel, material hardness >55HRC
Application range of high speed milling
Diameter (according to workpiece geometry, accuracy)
Type (roughing, finishing, grooving, 3D contouring, edge machining-)
Shape (ball cutter, round nose cutter, multi-blade milling cutter ..)
Materials (High Speed Steel, Carbide, Cermet, Diamond, Cubic Boron Nitride CBN)
Tool coating (TiN, TiCN, TiAlN -)
Quality (radial runout, shape accuracy, dynamic balance, rigidity)
2. High-speed spindle
In fact, the high-speed spindle is like the high-speed and high-power engine in an F1 car.
The spindle can be roughly divided into two specifications:

3. High dynamic performance of each axis
In fact, the bed structure of the machine itself is like the chassis of a car, strong and safe to absorb shock and vibration.
Traditional hard rails can achieve better accuracy through adjustments on the machine, but it cannot achieve the high-speed machining that linear slides can achieve. High-speed axes and solid bed structure, acceleration is the key factor, high-acceleration axes reduce time waste, better cutting surface, and low tool wear.
4. High-speed milling controller CNC
In fact, the controller is like a driver. Its operating skills determine the outcome of the car. It needs to be forward-looking, sensitive and quick to react.
5. CAM machining strategies for high-speed milling
Actually, there are many paths to get from one point to the next, but all paths have different effects in speed, surface, etc.
With bearings => high torque, the current excellent speed can reach 54,000 revolutions.
Bearingless (gas driven) => low torque, but very fast (>100krpm).
High torque allows cutting of larger materials, using larger tools and harder materials. High rotational speed allows for faster cutting rates and HSM effects.
