Attachment for Single-step Machining of Complex Features

The Eppinger shaping attachment recently introduced by Exsys Tool enables single-step machining of numerous difficult-to-cut features, including grooves, chamfers, Torx® screw heads, splines, and gear teeth. Permanent grease lubrication of the attachment’s bearing surfaces helps reduce wear and tear on the machine tools that employ the device, the company reports.

The shaping attachment drives the cutter into the workpiece in the Z axis at cutting speeds up to 1,000 SPM. At the end of each stroke, an integrated lift-off mechanism returns the cutter to the starting position without drag, protecting the surface finish of the component and the cutting edge of the tool.

With a working stroke of 1.3 in. and maximum feed of 0.006 in. per stroke, the attachment can produce maximum groove widths of 0.31 to 0.34 in.

The attachment’s capability to machine difficult features in a single setup increases production throughput, while its permanent lubrication, lift-off mechanism, and rigidity minimize machine tool wear and downtime that can result from performing gearmaking-type operations, the company states.
