Processing impact editing
(1) The diameter of twist drill is limited by the aperture, the spiral groove makes the drill core thinner, the drill bit stiffness is low; With only two ribbed guides, the axis of the hole is easy to skew; The horizontal edge makes centering difficult, axial resistance increases, and the bit is easy to swing. Therefore, the shape and position error of the drilled hole is large.
(2) Twist drill before and after the tool surface are curved, along the main cutting edge of each point of the front Angle, the rear Angle is not the same, the front Angle of the horizontal edge of -55°. Poor cutting conditions; The distribution of cutting speed along the cutting edge is not reasonable, and the cutting speed of the tip with the lowest strength is the highest, so the wear is serious. Therefore, the hole precision of processing is low.
(3) The whole edge of the main cutting edge of the drill participates in cutting, and the cutting speed of each point on the edge is not equal, which is easy to form spiral chips and difficult to discharge chips. Therefore, the chip and the hole wall extrusion friction, often scratch the hole wall, the surface roughness after processing is very low.
