Socket Machining

 
 

Perfect fit for back spindle of Swiss Machines

Less Tool Pressure  |   Shorter Cycle Times

Traditional Methods of generating these features include:

End Milling - A small diameter endmill is driven by a high-speed spindle to create hexalobular (6-lobe) sockets. This method has some flexibility but,

 Requires a high speed spindle  | Involves complicated programs | Time consuming process

Shaper Duo:  No need for high speed spindle | Simple program | Low cycle time

Conventional Broaching / Wobble Broaching - A sequence of form tools is pushed through a drilled hole until the desired socket size is formed. In most cases, dedicated  broaching machines are purchased for high production parts. This equipment has a stroke length; a max distance they can travel. For a specific job the stroke would be defined by the  broach length, the part material, and amount of material to be removed. 

Need tool for each socket size |  Hydraulic pressure build up pushes part effecting tolerances

Shaper Duo:  Inserts can generate range of socket sizes |  Low tool pressure  | No special equipment needed   |   Consistant tolerances on parts

Low tool pressure is key for consistent part production
