Application The SG 175 support grinder is designed for grinding the conical seating surface of valves of medium speed diesel engines on a standard lathe. Handling The support grinder is clamped in the toolpost located on the top slide of the lathe. The grinding angle corresponding to the required valve seat angle is adjusted by turning the top slide of the lathe to an angular position which corresponds to the valve seat angle and which is defined by the template supplied with the grinder. The valve stem is clamped in the chuck of the lathe and the valve face is ground by feeding the grinding wheel into the rotating valve face. Features The precision grinding spindle is permanetly sealed and lubricated for lifetime accuracy. The wheel guarding system is designed to the prevailing safety regulations. The cone-shaped head of the template is provided with a bore receiving the dressing diamond so that the grinding wheel can be properly dressed after adjustment of the grinding angle.

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.
