The WMX trowel groove type is used for finishing, and a finish of 0.4 or more can be obtained while maintaining a high feed of 0.5-0.8 mm/r. In the processing of rectangular threads, the 266-blade with rail positioning from Sandvik Coromant makes the change in the profiled shape smaller and makes it easier to guarantee the quality of the machining. In addition to sleeping cars, deep hole drilling machines and floor boring and milling machines are also important for spindle machining. When machining 80-deep deep holes, it usually requires 45 kW of power, 300 l/min of coolant flow, 1.5 Mpa of cooling pressure, and 1.5 KNm of torque. This condition is only required for processing 4 m deep holes. minute. After machining, no need for boring can meet the requirements. Slewing bearing machining The inner hole, end face, outer circle and raceway of the turning slewing ring are all completed on the vertical car; for high-efficiency tooth machining, it is completed on the gear milling machine; the bolt through hole is completed on the vertical drilling center. The choice of the vertical car will not be repeated here, focusing on the milling process. Since wind power does not have strict requirements on the accuracy of the slewing bearing teeth, it is usually able to meet the requirements of use at the 9-10 level, so the tooth machining can be simplified into two steps of rough and fine milling. For rough milling, in the case of machine rigidity and fixture rigidity, it can be processed with a feed of more than 400, and fine milling can use a larger feed. It has been proven that Sandvik Coromant's rough and fine gear milling cutters and corresponding inserts perform exceptionally well. For drilling of threaded bottom holes and bolted through holes, it is recommended to use a two-axis vertical drilling center with the Corodrill 880 shallow hole drill for efficient hole machining.
