Note: ① grinding Cylindrical grinding or finishing in general on the basis of. Hand in cylindrical grinding lathe, coated abrasives between the workpiece and the lap, the workpiece driven by flat cutting disc rotation of the spindle lathes, and research support with hand axially reciprocated oncrete cutting discs.
Grinding diagram (8)
② mechanical polishing on cylindrical grinding machine generally used cylindrical grinding ball type parts.
2) grinding the inner circle
Description: After grinding the inner circle need grinding, fine or fine boring hinges conducted, usually by hand grinding. Sleeve for the opening lap, set in taper spindle abrasives applied between the workpiece and the lap, holding the workpiece axially reciprocated. After grinding a certain time, to adjust the direction of the big reinforced concrete cutting disc end of the tapered mandrel sleeve, so that the diameter swell, to maintain pressure on the workpiece bore wall.
3) grinding plane
Description: grinding plane generally conducted after grinding. When hand-grinding flat, coated abrasives in grinding plate (lap) on hand for linear reciprocating motion artifacts or "8" shaped movement. Some time after grinding, the workpiece is turned 90 ° ~ 180 °, to prevent inclination of the workpiece. For topical facets to be RESEARCH, square hole, slit, etc. on the surface of the workpiece can also be a handheld grinding lap. Larger quantities of simple concrete cutting wheels plane parts also on the ground in a surface grinding machine.
