Machine for diamond cut MDK-2




Certificate


Type: grinding machine
Model: MDK-2
Manufacturer: CJSC Leader


1. Application, description and recommendation

Machine of the modek MDK-2 is applied for surface grinding, crystal diamond cutting with mass within 0.01-30carats in diamonds.
Machine is simple,reliable. It provides necessary conditions for obtaining of diamonds of the highest
(III Exellent) quality due to its new design of the lower poppet (tailstock) sleeze presenting droping of the cutting disk (plate) during operation.
Machine bed (frame)is made of steel pipes of rectangular section 100o100 mm with all-welded structure. The table is of steel plate with thickness of 20mm, faced by flexible PVC.
For desired precision and purity of treatment it is necessary to install the machine on foundation(reinforced concrete slab with thickness less than 160mm) far from machines operating impact load. Machine is levelled by 4 adjusting bolt on the bottom of the bed and fixed by 4 anchor collet bolts. Ccidental clearance between the bed basis and bottom is poured by liquid cement and sandy mortar with proportion 1/2: its hardening must occur during 7 days.
Electrical equipment of the machine is performed for connection to the three-phase alternating current network with voltage of 220/380 V. Necessary protection is provided.

Before the first starting it is requested to perform the following :
Thoroughly to clean the machine from contaminations; especially its poppet sleeze and cutting disk;
- To be conviced of the appropriate design of the machine level;
- To check reliability of the poppet sleeze fixation in any position;
- To be convinced og serviceability and normal functioning of all operating controls;
- To connect the machine to the serial grounding grid.
