Trunnion Machine Smooths Shop’s Workflow
This article looks at an automotive aftermarket supplier that consolidated its multi-machine process into a single machining cell.
Time in the cut is a universal measurement for any metalworking shop. The longer a machine tool is making chips, uninterrupted, the more productive that machine is.
This article, “Rotary Transfer Reduces Manufacturing Steps and Opens Opportunities,” looks at an automotive aftermarket supplier that consolidated its multi-machine process into a single machining cell. This move has opened up additional capacity for the shop to take on more work for its customers.
The new cell is built around an eight-station BTB rotary transfer machine that is sold and serviced by Gosiger High Volume. The machine uses a trunnion configuration, which allows access to both ends of a workpiece for simultaneous machining while it is gripped in the center by the trunnion.
Like all multi-spindles, with each index of the trunnion, a complete part is ejected. It’s a highly productive system and has allowed the shop, Tramec Sloan, to expand its capacity into other areas. Click here to read the full article.
Sometimes a shop doesn’t do enough turning work to justify the purchase of a CNC lathe. But when it needs to produce precision turned parts, even if for a very small lot size, the shop needs a solution.
Producing a keyway, spline or similar longitudinal feature on a turned part usually necessitates an additional, time-consuming, secondary operation on a broaching or slotting machine. That means moving the part to and from a secondary operation, an extra setup, additional labor and hourly machine costs and all of the other headaches that go with secondary operations.
Here's a broad look at different ways to approach workholding, from bar feeders to collet chucks to robotics.
