Regular checking of the lathe bed levels ensures that turning remains precise along the entire length of the machine.
This is one of the largest recorded Mitchell lathes. It was built for truly heavy work with a swing over the bed of 44 inches, and an incredible 64-inch swing in the gap, all over a centre distance of 180 inches (15 feet). It was powered by a 20 horsepower electric motor and could spin workpieces weighing tonnes at speeds between 10 and 400 rpm.
The work performed on a Mitchell lathe was as varied as British industry itself. The machines were designed as general-purpose centre lathes, capable of a wide range of turning operations, including turning, facing, screw cutting, and boring. mitchell of keighley lathe work
Use a high-precision machinist’s spirit level (accurate to 0.02 mm/m) across and along the bed ways. Adjust the leveling screws or shims until the bed is perfectly flat. A twisted bed introduces unwanted tapers into your turned workpieces. 2. Lubrication Architecture
: Not only does Mitchell of Keighley excel in producing new parts, but the company also offers repair and maintenance services for machinery and equipment. This includes re-machining worn parts back to their original specifications. Regular checking of the lathe bed levels ensures
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.
If you are cutting metric threads on an imperial leadscrew machine, you must keep the half-nuts permanently engaged throughout the entire process, reversing the entire motor/spindle to bring the tool back to the start of the cut.

Keighley is a West Yorkshire town shaped by textiles, engineering and the canals and railways that linked mill towns across northern England. From the 19th century into the 20th, small engineering shops proliferated in towns like Keighley to support agricultural machinery, textile mills, railways and domestic trades. Businesses named for their owners — “Mitchell & Co.” or “Mitchell (Keighley)” — fit this pattern: family-run, often multi‑generational, working on repairs, prototypes, and short-run components.
To understand Mitchell of Keighley lathes, you must first understand the environment that forged them. During the late 19th and early 20th centuries, Keighley was a powerhouse of British manufacturing, particularly in the production of looms and textile machinery. The engineering expertise required to build these complex machines naturally turned the town into a hub for machine tool manufacturing, producing lathes, milling machines, and planers for industries across the UK and the British Empire.
What specific of Mitchell lathe are you working with?
While the company's direct history has faded into the archives, its machines live on, still turning steel in workshops around the world. For the engineers and hobbyists who use them today, a Mitchell of Keighley lathe is more than just a machine; it is a working piece of history. The work of maintaining and running these lathes keeps a vital part of Britain's engineering heritage alive, one chip at a time.
