The turning tool used in ordinary lathe requires chip breaking when turning. How to grind it?

if it is 45# steel, the cutting groove of 9 turning tool is generally 4-6 mm wide, and its length should run through the cutter head, with a distance of about 1-2 mm from the cutting edge, and the depth of 5 mm is more suitable for round appearance.

if the width of the alloy knife is a little wider, but not more than 8mm, the cutting head will face upwards when grooving, aiming at the edges and corners of the grinding wheel, and grinding bit by bit.

the cutting surface should not be ground into multiple surfaces, but should be ground flat.

the end face (the edge of the plane above the knife) is slightly higher. Not too high. Otherwise, it is easy to be violent. The shape of cutting depends on the number of revolutions of the lathe.

cutting amount. And slotting. The number of revolutions is generally 5 to 8. Of course, depending on the size of the workpiece. The groove should be 2 mm away from the edge of the knife. Open it into an outer figure.
