concrete cutting blades Grinding diagram Method

1) Cylindrical Grinding 

Note: ① grinding Cylindrical grinding or finishing in general reinforced concrete cutting disc‍ on the basis of. Hand in cylindrical grinding lathe, coated abrasives between the workpiece and the lap, the workpiece driven by rotation of the spindle lathes, and research support with hand axially reciprocated. 

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 polishing discs‍ between the workpiece and the lap, holding the workpiece axially reciprocated. After grinding a certain time, to adjust the direction of the big 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 reinforced concrete cutting wheels‍ plane parts also on the ground in a surface grinding machine.
