Operation

RECOMMENDATIONS FOR OPERATION (DCW) of the trade mark “RIDDER”

1. Diamond cutting wheels (DCW) of the form 1A1R to be used only for natural and synthetic ornamental stones marble, granite, glass, corundum, ceramics and other nonmetallic materials cutting.

2. To follow modes and conditions of cutting “RIDDER”:

3. To choose correctly the type of the disk according to the material to be cut.

4. To keep up to the conformity of the maximal speed of rotation of diamond cutting wheels and of the shaft of the equipment.

5. To keep up to the conformity of the size of a fit aperture to the size of the fit shaft, neck when fitting disks impacts sideways and from above are not allowed.

6. Misalignement or jamming of the cutting disks is not allowed.

7. The material to be cut must be clamped strongly.

8. Strong pressure is not allowed feeding should be uniform.

9. To work with a safety casing and in goggles.

10. To provide a continuous and sufficient supply of water.

11. To avoid rigid shock loads at immersing the tool in the material.

12. To observe safety requirements at work with manual electric and pneumatic tools (for diamond cutting wheels diameter 150 and 200 mm).

13. The newly purchased diamond cutting wheels “RIDDER” as well as “greased” in process of work is to be opened, having made 2-3 parallel cutting on an abrasive wheel silicon carbide mark 64C on a ceramic bond for the depth not less than the height of diamond bearing layer.

14. In case of the wheel stop of a circle to switch off the machine tool immediately and to find out the reason, but not press the wheel. Probably the wheel is turned on a spindle of the machine tool because of discrepancy of the fitting sizes or because of malfunction of clamping flanges (small diameter, lack of flatness etc.). Or there is a price of a broken diamond in the cutting demanding its removal, or the wheel “was greased”.

15. The stone cutting machine tools should have the blocking providing its stop at a stopping of cooling liquid delivery.

16. To carry out technical requirements to the stone cutting equipment according to its passports or to TR. The basic requirements to the equipment:

The name of the basic parameters of the stone cutting machine tools

DCW diameter, mm

250-300

400

Radial run-out of centering surface of a spindle, mm, no more than

0,03

0,05

Face run-out of a basic surface of a spindle, mm, no more than

0,03

0,06

Deviation from parallelism of the axe of the spindle relativly to the table, mm/m, no more than

0,10

0,20

The wheels are certificated by the Centre of certification of diamond and abrasive tools (CC “Almazabrasiv”).
