BGM BALL VALVE BALL GRINDING MACHINES
Grinding machines designed for manufacturing of metal balls of
high precision valves. Balls up to 82.7” inches in diameter can be
machined. Machining is done with segmented grinding wheels.
Power range of the vibrationless quality spindle is 29.5 – 123.4 hp.
Extra equipment includes automatic ball measurement, diamond
wheel dressing and automatic tool change.

Highlights
• Rigid machine also for coated balls.
• Advanced grinding force control against
ball surface.
• Diameter measuring before, during and
after grinding.
• Spindles and linear axis protected against
dust.
• 2-axes centering function for spindle
position (ball center measuring with probe).
Technical description
• BGM-600 and 800 machines have slant bed
grinding spindle axis and BGM-1300, 1800
and 2100 machines feature horizontal grinding
spindles.
• In all machines there is a possibility to adjust
Y-axis for positioning of the spindle compared
to ball’s horizontal centre line.
• The machine bed is designed so that the
grinding waste is flushed away from inside of
the machine to liquid handling system.
• Servo controllers – braking energy can be
fed to the use of other motors or back to the
factory electric grid.
• The control of the machine is done from 12”
NC-operation panel, graphical user interface.
