Acme Gridley Screw Machine Services
What Are Acme Gridley Multi-Spindle Screw Machines?
One of the leading names in turned parts manufacturing equipment, Acme Gridley screw machines come in six and eight spindle designs. They can be used to create slots, tapers, knurls, and other designs with tight tolerances, and with material sizes ranging from 0.25 inches to 3 ½ inches.
Thanks to their widespread use, there are many different general and specialized attachments that each spindle can use to machine your components. While they aren’t designed to quickly change between many different low-volume production runs, they’re optimized for high-speed, high-volume production that doesn’t sacrifice precision for speed of manufacturing.
Capabilities of Acme Gridley Screw Machines
Acme Gridley multi-spindle screw machines can easily transform bar stock into precision components, with each spindle performing one of the following tasks:
- Tapping
- Threading
- Milling
- Drilling
- Reaming
Screw machines with up to eight spindles can quickly move from one task to another, providing multiple machining steps in quick succession. This effectively combines several machines into one for efficient operations.
