How to achieve mirror grinding with grinding wheel
diamond grinding wheel
Achieving mirror polishing effect is not difficult, mainly using high-precision resin bond diamond grinding wheel.
Requirement of machines for mirror polishing:
High precision, rigidity and vibration reduction measures; the rotation precision of the resin grinding wheel spindle is higher than 1mm;
The amplitude of the grinding wheel frame relative to the table is less than 1 mm; the lateral feeding mechanism can accurately finely move;

Case study:




Grinding parameters

speed of the grinding wheel

15 ~ 20m/s

Work piece speed

50 ~ 100mm/min

Feed rate

3 ~ 5mm


Water and oil

Horizontal feed depth of 3 ~ 5mm, then make no feed grinding 20 ~ 30 times.

Dressing parameters

Dressing tools

Single crystal diamond point dress tools

Dressing speed

6 ~ 10mm/min

horizontal feeding

2 ~ 4 times

cutting depth

2 ~ 3mm each time

Each time the depth of cut is 2 to 3 mm, and no feed light is repaired once.

When mirror polishing, first use the vitrified bond diamond grinding wheel with grit 60# or less, make the grinding grains on the surface of the grinding wheel form many semi-blunt micro edges of equal height, when grinding only cut off the micro chip and the surface roughness reaches Ra0.08 ~ 0.04mm.
Then use resin bond grinding wheel grit W14 ~ W5 after fine dressing, for mirror polishing under proper grinding pressure. After a certain time of friction polishing, finally reach surface roughness ≤Ra 0.01mm. +86-371-8654-5906 +86-18339903057 Zhongyuan Rd, Zhongyuan District, Zhengzhou, China
