A turning tool is a tool that has a cutting portion for turning operations. Turning tools are one of the most widely used tools in machining. The working part of the turning tool is the part that generates and handles chips, including the cutting edge, the structure that breaks or rolls up the chips, the space for chip removal or storage, and the passage of cutting fluid.

Features and requirements of turning tool blades

(1) High positioning accuracy After the blade is indexed or replaced with a new blade, the change in the position of the tool tip should be within the allowable range of the workpiece accuracy.

(2) The blade should be clamped reliably. The contact surfaces of the blade, the shim, and the shank should be in close contact and can withstand impact and vibration, but the clamping force should not be too large, and the stress distribution should be uniform to avoid crushing the blade.

(3) Smooth chip removal There is no obstacle on the front of the blade to ensure smooth chip discharge and easy observation.

(4) Easy to use, it is convenient and quick to change the blade and replace the new blade. For small size tools, the structure should be compact. When meeting the above requirements, the structure is as simple as possible, and the manufacture and use are convenient.
