The current series TSA, TSI, TSP, TSAV,of the external-driven GMN tool spindles follow the first grinding spindles made by GMN in the 1930s. Then and today, we provide simple, but robust and functional spindles that reliably fulfill their tasks. Depending upon the customer’s tool selection, spindles are available with various tool holders.

Tyrolit centerless grinding wheels can grind workpieces from a few millimeters to several meters in length with maximum precision and cost-effectiveness, ideal for large series of identical parts. Centerless grinding wheels are notably thick compared to their diameter. Special pressing processes, adapted specifications, and sometimes split grinding wheels ensure homogeneous density distribution. Tyrolit offers a complete assortment of grinding wheels, regulating wheels, and dressing tools. Continuous product development guarantees high stock removal, tight tolerances, and fine surface results. Resin-bonded CBN grinding tools with a fiber-reinforced composite carrier body offer up to 80 percent less weight and better absorption properties, enhancing grinding results and tool life. Vitrified-bonded wheels use innovative sintering technology to prevent abrasive grain breakage. Lightweight diamond wheels are available for centerless through-feed grinding, gentle on machine spindles.

Machine Base Heavily ribbed cast iron structure for vibration-free performance. Adjustable slideways for wheelhead infeed and workhead traverse. Wheelhead Box type monobloc noted for its excellent vibration dampening characteristics. The precision motor grinding spindle is permanently sealed and lubricated. Workhead Located on a swivel plate which can be set to the required angular position by means of a wide-spaced scale. Collets for perfect valve alignment. Dressing Attachment The dressing attachment is permanently mounted on the worktable for rapid wheel dressing. Wet Grinding Coolant is delivered by an industrial type flood pump. The baffled coolant tank is easily removed from the machine base for cleaning. Electrical System Individual grinding spindle motor, work spindle motor and coolant pump motor all controlled by switches grouped in front of the wheelhead for ease of operation.

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.

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.
