Profile grinding machine SMG150SF3 successfully delivered to the customer

In December, we completed the delivery of a highly functional CNC profile grinding machine SMG150SF3 at our Customer – one of the leaders of the Russian aviation industry.

The customer plans to use the machine in tool production for the production of broaches and gear shaper cutters. The machine is dedicated for flat and profiled surfaces and also spine keys with involute and trapeziform profile. Processing of crushers( knurlers) outer profiled surfaces and processing of flat and round broaches on the front and back surfaces.
During SMG150SF3 comissioning works the form broach for "dovetail" details and gear shaper cutter were procesed.
Achieved parameters:

The error of profile drawing by the dianond roll with deviations of 0,003 mm- less 0.07 mm (Fig. 1)
The actual error of the circumferential pitch of the gear cutter sharper with a diameter of 105 mm and 68 teeth between adjacent teeth is 0.002-0.004 mm (Fig. 2)

Own-developed software is simple and convenient. It allows the operator to enter the parameters of the part from the drawing in the dialog box and perform processing without adjusting the control program.

The MARPOSS contact sencor is used to measure the actual tooth pitch with simultaneous zero-point settl. for each tooth before the processing. The overdimention distrubution for subsequent processing is performed on the gearwheel cutter.
To measure the processing part profile the machine includes the possibility to install in the working area of measuring machine -contour measuring station. This allows to measure processing parts and also processed parts without removing them from a special installation device. This technology allows to reduse the part processing parts and eliminate the possibility of bringing expensive workpieces into defective products.
