Drive Pins reduce slippage in hard turning applications.
Press Release Summary:
Micro-serrated, hard-coated Neidlein face driver drive pins reduce or eliminate part slippage, reduce scrapped parts, and increase turning productivity. If part slips, it will not remove serrations or coating, and pins can be used again. Products achieve circular run outs of less than 0.0007 in. in long production runs. Drive pins can be used with SB/FSB and FFB face drivers and all special application face drivers for hard turning.

Logansport Matsumoto at IMTS 2004: Neidlein Face Drivers with New Serrated/Coated Drive Pins Reduce Part Slippage, Improve Turning Productivity
Logansport, IN - Hard turning is now easier and more productive with new Neidlein face driver drive pins from Logansport Matsumoto Company. Micro-serrated and hard-coated, these unique drive pins reduce or eliminate part slippage, dramatically reduce scrapped parts, extend performance life over diamond-coated drive pins, and increase turning productivity. They will be introduced in booth E-2055 at IMTS 2004 (September 8th-15th Chicago's McCormick Place).
Finishing hardened work pieces using face drivers is gaining greater acceptance with the advanced capabilities of these tools. However, a drawback has been the ability to successfully clamp hardened work pieces, while, at the same time, machining them entirely in a single operation. To insure proper workholding, a suitable driving element is needed which can handle high torque demands and still be cost effective to make hard turning possible. To do this, Neidlein has developed a system of micro-serrated and hard-coated drive pins mounted around the face driver (which has proven successful for many turning applications, but especially hard turning).
Life expectancy for micro-serrated and hard-coated drive pins is six to ten times longer than diamond-coated ones. These new pins grip more firmly than diamond-coated pins. Even if a part should slip with the new pins, it won't remove the serrations or coating as quickly as is the case with diamond-coated products. Also, if slippage occurs, the pins can be used again, unlike diamond-coated ones that would need replacing. In addition, to handle a greater work piece variety, these pins grip on a smaller surface area.
Given the proper parameters, these drive pins can achieve circular run outs of less than 0.002 mm/0.0007" in long production runs.
Neidlein's serrated and coated drive pins can be used with its SB/FSB, and FFB standard face drivers and all special application face drivers for hard turning.
Neidlein makes a complete line efface drivers that use quick-change center points and drive pins for increased productivity and cost efficiency. An online video at its Internet Website is available to see them in action. The LMC Workholding line includes...
o LMC and Matsumoto hydraulic power chucks, cylinders and wheel chucks;
o LMC Rotary tables for single and multiple axis CMC turning, EDM and other machining applications;
o Atling Steady Rests;
o Neidlein face divers, as well as live and dead centers.
