Clamping parts - Import export

Based on its many years of experience in the development and production of high-quality machine components, GMN has chosen to specialize in the production of efficient, long-life sprag type freewheel clutches. The standardized model series offer a large selection of feature options to furnish effective freewheel clutch solutions for almost any field of application. The functional principle of sprag type freewheel clutches is based on static friction. A certain number of sprags are in constant friction contact with the connecting parts. Sprags are components with variable height. They are uprighted when the connecting parts are rotated and clamped between the connecting parts while there is static friction between sprags and connecting parts. The static friction is guaranteed by a specific geometry (clamping angle) of the sprags to the connecting parts. GMN sprag type freewheel clutches can be used as indexing clutches, backstops or as overrunning clutches.

Selfcentering Steady (Option) Selfcentering steady rests are available to fit on the swivel plate slideway for additional support of long stem valves. Both the workhead and the stready rest are adjustable along the swivel plate to clamp each valve on that part of the valve stem which normally travels in the valve guide. The combination of collet chucking and the unique Hunger steadying provides double support of long valves to ensure the ultimate in valve refacing accuracy. Oscillating Equipment (Option) An oscillating equipment for automated power traverse of valve face across the grinding wheel is available to ensure efficient stock removal and superior finish. The stroke of oscillation is infinitely adjustable. Automated Infeed (Option) Power infeed is available for automatic grinding according to a preselected program. The feed rate, the total infeed and the sparkout time can be easily selected.

Machine Base Heavily ribbed cast iron structure with integrated dove tailed slideway for the workhead and steady rest. The machine base houses an industrial type flood pump for delivering coolant to the grinding site and a baffled drawer type coolant reservoir which can be drawn out for ease of cleaning. The machine base houses also the control panel for the motors. Grinding Spindle The permanently sealed and lubricated grinding spindle slides on a swivel plate which is provided with an integrated dove tailed slideway. The swivel plate is set to the desired valve angle by means of a wide spaced scale. Steady Rest An unique selfcentering steady rest is provided for additional support of long stem valves. Both the workhead and the stready rest are adjustable along the slideway on the machine base to clamp the valve on that part of the valve stem which normally travels in the valve guide.
