Machine for grinding and lapping of valve

MACHINES FOR GRINDING AND LAPPING OF THE PIPELINE VALVE DN 50...1000 MM (2...40'')

PURPOSE:

The machines are designed for grinding and lapping the flat sealing surfaces of the housings and wedges of the gate valves, housings and spools of the stop valves (globe valves), safety valves and other flat surfaces.

TYPE OF VALVE:

• gate valve;
• globe valve;
• safety valve.*

DN OF VALVE:

• PKTBA-SPSH-1: DN 50...600 mm (2''...24'') ;
• PKTBA-SPSH-2: DN 600…1000 mm
(24...40'').

EQUIPMENT ADVANTAGES:

• The tilted table with adjustable tilt angle simplifies the procedure of the machined part installation on the machine and allows one to machine sealing surfaces at various tilt angles.
• The coordinate device ensures the part installation by three coordinates (tilt angle and positioning with respect to the x and y axes).
• To make installation procedure of workpiece more simple the column can turn on 315° relatively its base.
• Digital indication of spindle rotational speed is provided.
• The tool drawer unit allows to store replaceable accessories.
• Uniform lapping plate and the adapter with eccentric allow us to achieve high flatness of the surface (rule out removal of different quantities of material during the lapping-plate rotation because the external circumferential velocity is higher than the internal one).
