Okuma's flat turning for machining polygonsClick image to enlarge

A new video from Okuma America Corp. shows how flat turning, a feature on the OSP control, is used for machining polygons. Flat Turning allows for continuous spindle rotation, which reduces both machining time and part cost while eliminating the need for time intensive milling operations.

 

By synchronizing the rotation of the rotary tool spindle (M-spindle) with the rotation of the main spindle, both flat surfaces and radii can be manufactured in a single process.

The workpiece and the cutter are rotated synchronously with the defined rotation frequency ratio. This frequency ratio is maintained by synchronously controlling the spindle motor and the rotary tool motor. M codes are established in flat turning mode to set the ratio between the rotary tool spindle and the main spindle.

When using the Flat Turning feature flat edges are produced directly on the lathe in a single process using polygon cutters. The part and cutter head turn in the same direction, synchronizing rotation of the revolving tool spindle (M-spindle) with the main spindle to generate polygon shapes.
