Mitchell Of Keighley Lathe Work

In the later years of production, Mitchell developed the , with models like the GVM6 and GVM7. These were designed to meet the demands of higher-speed machining. The GVM6 featured a 6½" centre height , while the GVM7 had a 7½" centre height . To achieve a maximum spindle speed of 1000 rpm , these later models incorporated advanced features such as vee-ways (V-shears) for enhanced bed stability and Gamet precision bearings . The GVM series represents the evolution of Mitchell’s engineering, showing their commitment to modern manufacturing techniques while retaining the classic robust design they were known for.

The longevity of a Mitchell lathe relies entirely on its oil film.

Later models transitioned to hardened slant-type V-beds , which are more durable and provide better alignment than earlier flat-bed designs.

Use the robust power-feed mechanisms built into the apron. Ensure the clutch is properly adjusted to prevent slipping under heavy loads. Large-Diameter Turning (Utilizing the Gap Bed)

The brand expanded through the mid-20th century under various joint corporate names, including Woodhouse & Mitchell and Town Woodhouse, before being taken over by the B. Elliott Group in 1967. Mitchell lathes became a staple in maintenance shops, heavy repair facilities, and naval vessels across the Commonwealth due to their unyielding cast-iron rigidity and predictable manual controls. Key Technical Specifications mitchell of keighley lathe work

Mitchell of Keighley (often just "Mitchell’s") was a well-regarded UK machine tool dealer, reconditioner, and manufacturer of small lathe accessories. They were based in Keighley, West Yorkshire. They didn’t make large industrial lathes from scratch but rather sold second-hand machinery (often Colchester, Myford, Harrison, etc.) and produced items like vertical slides , milling attachments , tool posts , and backplates for small lathes (e.g., Myford, Drummond, Boxford).

Periodically drain the oil to remove any fine metallic particulate that accumulates from gear wear, flush with light flushing oil, and refill. Apron and Way Lubrication

Unlike older flat-belt-driven lathes, Mitchell machines are predominantly all-geared headstock lathes.

Place the machine on a thick, reinforced concrete floor. In the later years of production, Mitchell developed

Ensure the half-nut mechanism engages cleanly with the robust leadscrew.

Because Mitchell lathes feature highly rigid cross-slides, they excel at facing large-diameter bar stock.

Once configured, a Mitchell of Keighley lathe is capable of remarkably precise work, holding tolerances to within a thousandth of an inch.

For standard English threads, the thread dial indicator on the carriage can be utilized to drop into the correct position on successive passes.

are excellent resources for original documentation and spec sheets. Are you running a Mitchell of Keighley in your workshop?

Choose a lower RPM range from the headstock levers. Mitchell lathes operate best at moderate speeds with high feed rates when roughing.

Use the fixed steady rest (bolted to the bed) to support the outer end of long shafts for boring or facing operations.
