Model B

Multi-spindle screw machines provide superior productivity over traditional single-spindle screw machines and lathes. In a multi-spindle machine, each spindle has two opposing tools cutting in the work zone, allowing for multiple operations to be done at once. Allowing parts to be machined incredibly fast, and a complete part to be dropped with every index of the revolving head. The Davenport Model B has the fastest revolving head index speed on the market. This speed along with various attachments developed by Davenport engineers, have given the machine flexibility to complete almost any machining operation.
