It was the cover story entitled: "Micro-Precision Machining" by Elizabeth Modic

The Microconic system benefits orthopedic bone screws, miniature precious metal components for pacemakers, and other implantables; machined surgical components made of hypodermic needle tubing; and surgical instrument components. Here’s one example – dental implants.

Material:
Titanium alloy bar stock

Machine:
Star SR20 Swiss-type CNC Automatic Lathe

Previous method:
The dental implant was machined almost entirely on the main spindle of the machine due to the need to have a powerful grip on the bar for a high-force, blind-hole, hexagon broach. Very little work was done on the pick-off spindle, so that sat idle for most of the cycle.

Cycle time reduction:
164 sec. to 98 sec. per part; 40% improvement achieved by moving all ID machining operations to the pick-off spindle, where they were performed in shaded time while the main spindle completed the OD. This was previously impossible to do with legacy collets, because the broaching force would push the part back in the collet. The 0.001" concentricity requirement of ID to OD could not be reliably achieved with legacy extended-nose collets, and they damaged the critical surface finish on the OD of the implant.

Matt Saccomanno’s Microconic collet-type workholder for small part machining was inspired by his experience in a Swiss screw-machine job shop.

Cost savings:
Production rate went from 18pph to 32pph, a 44% cost savings. In addition, a hand deburring operation was eliminated due to the cut-off being on the opposite end.

ROI:
Cost of the Microconic system was recouped in 64 production hours; a $14,015 saved in direct production costs of a 10,000-piece order.
