1. The front.The surface on which the cuttings flow. It can be a plane or a surface to make the chip flow out smoothly.
2.The back. The surface opposite to the transition surface on the workpiece, also known as the back knife surface, is tilted at an Angle to reduce friction with the workpiece.
3.Vice rear. The surface on a tool opposite to the machined surface at an Angle to avoid scratching the machined surface.
4. Main cutting edge. The intersection line between the front and back of the tool is responsible for the main cutting task.
5. Auxiliary cutting edge. The intersection line between the front and rear of the tool is only responsible for a small amount of cutting tasks.
6.Point.The intersection point of the main cutting edge and the auxiliary cutting edge, which is not absolutely sharp, is generally in the shape of an arc to ensure that the tip has enough strength and wear resistance.
(1) Make the knife body turn to the left according to the main Angle, and make the head turn up according to the size of the main back Angle.
(2) Then make the knife body to the right according to the size of the side Angle, and make the knife head upward according to the size of the side back Angle, and grind the side back seedling to produce the side Angle and side back Angle.
(3) Make the front knife face tilt according to the size of the front Angle, make the head tilt up or down according to the size of the blade inclination, and grind the front knife face.
(4) Then grooving can be done by the edge of the grinding wheel.
(5) Finally, chamfer and finish.
