T-slot milling cutter is a difficult tool for machining. Not only the cutting resistance is large, but also the cutting force belongs to the radial force. Although the cutting force of the drill bit is large, it belongs to the longitudinal force, and the spindle can absorb most of the cutting force. Therefore, the T-slot milling cutter must have strong structural rigidity, good cutting ability, and smooth chip removal.
The reproducibility of the insert type T-slot milling cutter insert is the key point. Only with good reproducibility, the cutting insert type tool has practical value.
