[Medium glass] 1. Grinding wheel trace: related to cutting amount, cutting speed, cooling water factor;
2. Polishing marks: related to yttrium oxide, polishing liquid, wool wheel defects, replacement of polishing liquid or wool wheel;
3. There are spots: the friction wheel and the glass friction are generated, mainly because the direction of the cooling water flow is inconsistent with the rotation direction of the grinding wheel;
4. Vertical edge width is inconsistent:
A) Check the resin wheel pressure; B) Check each gold steel wheel; C) Check the grinding wheel direction; D) Check the rear conveyor belt; E) Check whether the beam splint is oxidized and adhered; F) Check the glass size.
5. Thick polishing marks:
a) insufficient water pressure; b) yttrium oxide mass and suitable concentration; c) too high grinding speed
6. Edge or corner rupture:
a) Grinding head grinding b) Water flow position c) Conveyor belt d) Cutting condition of each grinding wheel e) Resin wheel rotation direction, f) Check glass size.
7. Irregular edges (wavy edges):
a) individual rear splint protrudes, b) the rear splint has a sinking object, c) the transport chain mat is damaged;
8. Insufficient polishing of the corners:
a) confirm the grinding wheel cutting function, b) the front and rear chain clamp clamping conditions, c) the grinding wheel rotation direction;
9. The hypotenuse is not parallel:
a) adjust the input surface, b) adjust the clamping force;
10. Motor repeats stop:
a) fuse problem; b) power line input voltage drop; c) poor wiring contact; d) insufficient transmission tension; e) insufficient function of the polishing wheel cylinder, the solenoid valve is not working properly; f) the belt speed change fails to shift
11. There are block-shaped wear marks on the flat bottom, regular wear marks:
a) calibrate the polishing wheel; b) control the polishing wheel pressure.
12. The polishing wheel does not work or the workpiece cannot be worn:
a) The microswitch is in the wrong position; b) the cylinder pressure is too small.
13. No glass still works through the polishing wheel:
a) The control lamp is not turned off; b) The solenoid valve and microswitch are defective.
