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. Parts can be machined in faster cycle times than other multi-spindle machines. A complete part is produced with every index of the revolving head.

The Davenport Model B has the fastest production and index speeds on the market. Davenport has an expansive catalogue of attachments, providing solutions for a variety of small part applications.

Since 1900, The Model B continues to be the most economical, fastest multi-spindle screw machine available.
