SPC Innovations Inc. showcases Autor Engineering’s updated line of multispindle attachments, including the synchronous frontal milling (slotting) attachment with safety torque switch shown. The addition of synchronous attachments and CNC-controlled slides to traditional cam machines can increase productivity, reduce secondary operations and enable for quick job changeovers.

Operations such as frontal milling, cross drilling, off-center drilling, thread-chasing, milling of threads or flats, marking on flats and eccentric turning are typically not possible on a multispindle, and require a secondary operation. SPC Innovations displays its compact, precision attachments that move these operations onto the primary machine to drop parts complete. The attachments are driven by the machine’s synchronous tool drive (pick-up spindle drive), already available on most machines. These complex operations can be effectively integrated into most standard multispindles without spindle stopping. Cycle times and spindle speeds are typically not affected, the company says.

In addition to showcasing its advancements in multispindle machining, SPC Innovations’ booth features a live demonstration of SPC’s economical and modular In-Process Part and Tool Verification System for all production machine types on the shop floor.
