Single Spindle Screw Machining

We have 73 Brown & Sharpe single spindle screw machines to produce parts suitable for home appliances, lawn & garden products, as well as automotive markets. Our 73 Brown & Sharpe bar machines can handle round and hexagonal stock of raw materials with lengths up to 12".

Brown & Sharpe Screw Machined Products

These single spindle automatic screw machines can be equipped with a range of cutting tools, including collet pads, form tools, and special counterbores to create brown and sharp screw machined parts. Special attachments are utilized for handling additional threading, cross drilling, straddle milling, broaching, and recessing operations. Several features, such as external and internal steps, tapers, knurls, splines, broaches, as well as slots, can be incorporated in our screw machined parts without secondary operations. With our Brown & Sharpe Chuckers, we also turn eccentric features on metal bar stock with diameters up to 1½".
