Davenport Screw Machine Services
Ashley Ward, Inc operates 28 multi-spindle Davenports. Our 5-spindle Davenport screw machines are best suited for producing component parts below 3/4" in diameter. The Davenport Model B multi-spindle screw machine at our machine shop is equipped with threading, countersinking, and 5th position burring attachments for turning components with distinct features such as external threads, internal threads, and axial holes.
Acme Gridley Screw Machine Services
Ashley Ward also operates 50 Acme Gridley multi-spindle screw machines with bar diameters up to 3 1/2". Our Acme Gridley screw machines have either 6 or 8 spindles. The multi-spindle automatic screw machines can also be used for turning materials with diameters as small as 0.2". The 6-spindle Acme chuckers also enable us to turn parts with eccentric surface features. Besides typical turning features such as external & internal steps, slots, knurls, and tapers, we also produce pieces rolled with circumferential markings.
