Okuma Spotlights Flat Turning Feature for Machining Polygons in Video Series
The open architecture OSP control enables cost efficient flat turning of difficult to machine polygons.
A new video by Okuma America Corporation, a world leader in CNC machine tool manufacturing, shows how flat turning or polygon turning is achieved through Okuma’s OSP control.
Flat turning allows for continuous spindle rotation, which provides opportunities for considerable time and part cost reduction and eliminates 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 are able to 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 this 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.
The purpose of the video is to demonstrate how an open architecture control enables users to customize solutions that fit their unique needs and applications. This is the second in a series of videos that show how a CNC control can be used to innovate and drive business growth in machine shops.
