Features of milling
Milling refers to the use of rotating multi-edge cutting tools! It is a highly efficient machining method. Milling has the following characteristics:
The milling cutter is a kind of multi-edge cutter, and the number of teeth working at the same time can be stepped milling.
High-speed milling can also be used, so the productivity is higher
The milling process is an intermittent cutting process!cnc turning service，The moment the cutter cuts into and out of the workpiece, there will be shock and vibration. When the vibration frequency is consistent with the natural frequency of the machine tool, the vibration will aggravate the cutting edge and even damage the machine parts. In addition, due to The periodic change of the milling thickness causes the change of the milling force to also cause vibration, so the rigidity of the milling machine and the tool holder and the strength of the cutter teeth are relatively high.
The cutting time of the cutter teeth is short, although it is beneficial to the heat dissipation and cooling of the cutter teeth, but it is periodic
The thermal deformation of the cutting edge will cause thermal fatigue cracks on the cutting edge, and even cause the teeth to peel off or chipping.
Milling method
Milling can be divided into down milling and up milling, which are mainly named according to the cutting direction and feed direction of the blade rotation. The vertical component of the milling force is upward, and the workpiece requires a larger clamping force.
