Referring to fig. 1 to 8, the left end surface of the first movable table 7 is an inclined surface. Specifically, the inclined plane and the vertical plane form an included angle of 10 degrees, the upper part of the inclined plane is inclined to the right, and the lower part of the inclined plane is inclined to the left. Of course, the inclination angle of the left end surface of the first movable table 7 may be changed according to the parameters of the back angle surface of the milling cutter to be actually machined. The rear corner face grinding seat 5 is provided on the left end face of the first movable table 7 to be vertically rotatable and is located on the right side of the mounting portion 3. Specifically, the rear corner surface grinding seat 5 is disposed on the left end surface of the first movable table 7 through a pin 75 in cooperation with a bearing to be vertically rotatable, and a spring for rotating the rear corner surface grinding seat 5 downward is disposed between the rear wall of the rear corner surface grinding seat 5 and the first movable table 7. The rear facet grinding holder 5 is marked with rotation angle graduations around the pin 75 in order to control and display the rotation angle. In order to limit the rotation angle of the rear corner surface grinding seat 5, the rear corner surface grinding seat 5 is provided with a limit salient point 51, and the left end surface of the first movable table 7 is provided with a limit concave portion 76 which is matched with the limit salient point 51, so that the rear corner surface grinding seat 5 can only rotate by approximately 90 degrees.

Compared with the conventional locking mode, the structure clamps the holder 100 by locking the second locking screw 52 to deform and shrink the mounting hole 10. In the process of shrinking, most directions of the mounting hole 10 are shrunk at the same time, so that the deviation of the axis of the clamping hole 1001 relative to the axis of the mounting hole 10 can be reduced or even avoided, and the processing precision is improved.

Referring to fig. 1 to 8, when the holder 100 is fixed to the mounting hole of the rear corner surface grinding base 5 and the mounting hole faces forward and backward, the locking screw 1002 faces horizontally and horizontally. When the clamp holder 100 fixes and installs the milling cutter a through the clamp hole 1001 in cooperation with the locking screw 1002, the diameter of the clamp hole 1001 is always larger than that of the milling cutter a. Therefore, when the locking screw 1002 locks the clamping hole 1001, the milling cutter a will be shifted along the length direction of the locking screw 1002 (i.e. the axial line of the milling cutter a is shifted a distance along the length direction of the locking screw relative to the axial line of the clamping hole 1001), so when the clamping base 100 is fixedly installed in the installation hole of the rear corner face grinding base 5, the axial line of the milling cutter a will also be shifted from the axial line of the installation hole of the clamping base 100. When the holder 100 is fixed to the mounting hole of the rear corner surface polishing pad 5, if the locking screw 1002 is not in a horizontal orientation, the milling cutter a is biased in a non-horizontal direction with respect to the axis of the mounting hole by the holding of the locking screw 1002, and the distance between the milling cutter a and the upper end surface of the polishing pad 32 is changed by the bias, thereby causing an error in the rear corner surface polishing. Because the left end surface of the first movable table 7 is an inclined surface, and the milling cutter a needs to rotate 180 degrees to grind another rear angle surface after processing one rear angle surface, the offset of the milling cutter a in the non-horizontal direction can cause the grinding of the two rear angle surfaces to be dark and shallow, and the quality of the milling cutter a is affected. When the holder 100 is fixed to the mounting hole of the rear corner surface polishing pad 5, and the locking screw 1002 is oriented horizontally, the milling cutter a is biased horizontally by the locking screw 1002, but the distance between the milling cutter a and the upper end surface of the polishing pad 32 is not changed by the bias, and the polishing depth of the rear corner surface is not affected.

Referring to fig. 1 to 8, the blade groove grinding seat 8 is fixedly installed on the upper end surface of the left arm of the second movable table 2, and the installation hole of the blade groove grinding seat 8 faces forward and backward. The rear clearance surface grinding seat 9 is vertically and rotatably arranged on the blade groove grinding seat 8, and the mounting hole of the rear clearance surface grinding seat 9 faces left and right. Specifically, the rear clearance surface grinding seat 9 includes a rear clearance surface grinding seat body 901 and a connecting plate 902 which are perpendicular to each other, the connecting plate 902 is rotatably disposed on the blade groove grinding seat 8, and a bearing 91 which facilitates rotation of the rear clearance surface grinding seat 9 is disposed between the connecting plate 902 and the blade groove grinding seat 8. The blade groove grinding seat 8 is provided with a limiting groove 81, and the connecting plate 902 of the rear clearance surface grinding seat 9 is provided with a limiting protrusion 92 matched with the limiting groove 81, so that the rear clearance surface grinding seat 9 can be vertically rotated by 90 degrees and is arranged on the blade groove grinding seat 8.

Referring to fig. 1 to 8, in order to achieve the purpose that the rear dead point of the stroke of the second movable table 2 (i.e. the deepest position where the second movable table 2 can move backward) can be correspondingly adjusted while the first movable table 7 is adjusted up and down (i.e. the tool apron 6 and the rear corner face grinding seat 5 are adjusted), the following structure is specifically adopted for achieving the purpose of simultaneously machining the positions or the strokes of the seats through single-axis adjustment: the right arm of the second movable table 2 is provided with a second limiting block 212 for supporting the first movable table 7 at the rear of the first movable table 7, and the included angle between the supporting surface and the vertical surface of the second limiting block is 45 degrees. Preferably, the second stopper 212 is integrally formed with the first supporting block 211, and is fixedly mounted to the right arm of the second movable table 2 by screws. In addition, the rear end of the first movable table 7 is fixedly provided with a first stopper 77 for abutting against the second stopper 212, and abutting surfaces of the first stopper 77 and the second stopper 212 are parallel to each other.
