Process adjustment after the wheel weight is improved

1) Heat treatment of the wheel weight to eliminate internal stress.

2) To ensure the perpendicularity of the two through holes in the balance block, the remaining margin is 0.2mm when the +125 mm octagonal cutter head rough milling plane is 205 mm.

3) Pre-drill through-holes with a 17 mm plain taper shank twist drill, and then use the +28.9 mm common taper shank twist drill to a +28 mm flat-drilled flat drill, thus making full use of the horizontal machining center. The unique features enhance the efficiency of production. When the flat drill with central cooling is processed at a speed of 580 r/min, the feed rate is 135 mm/min, which is several times faster than that of a conventional taper shank twist drill.

4) Reaming to +29.8mm, pour 1×45. Angle, reaming to +30mm.

5) It has been found that the reason why the verticality is difficult to guarantee during processing is that the balance block is deformed during the clamping process. Therefore, when drilling, expanding, boring, and reaming, the surface of the +125 mm octagonal cutter is polished. For 205 mm hole end faces, loosen the pinch slightly to reduce the weight of the counterweight to ensure that the deep hole is perpendicular to the plane.

The wheel weights processed by the above processing technology is tested by the workshop, and the dimensions of the two +30 'mm through holes meet the drawing requirements, and the perpendicularity of the 205 mm hole end face and the A face also meets the drawing requirements, so it is proved that this method is feasible.
