Levers on the front of the headstock allow the operator to select various spindle speeds. These ranges are designed to provide massive torque at low RPMs for heavy roughing cuts, and higher speeds for finishing operations.

Because these machines have lower top speeds, they are perfectly suited for High-Speed Steel (HSS) cutting tools and traditional braze-on carbide tools. If you use modern indexable carbide insert tooling, ensure you select inserts with geometries designed to work effectively at lower surface speeds, or maximize the spindle speed on smaller diameter workpieces to achieve the correct surface feet per minute (SFM).

D. Mitchell & Co. established itself as a cornerstone of the British machine tool industry in the late 19th and early 20th centuries. The company scaled operations mid-century, absorbing fellow Keighley manufacturer Darling & Sellers in 1950 to step up the production of large center lathes. Levers on the front of the headstock allow

: A larger centre lathe with a slant-type hardened V-bed and substantial distance between centers (often 2.5 meters). : A heavy-duty model with a 12.5-inch centre height. Common Operational Features Mitchell of Keighley lathe - Practical Machinist If you use modern indexable carbide insert tooling,

Lock the saddle to the bed using the carriage lock bolt to prevent the tool from pushing the carriage backward. Feed from the perimeter inward toward the center.

A later example of the standard model, reflecting the UK's gradual shift to metrication in the late 20th century. This lathe had a bed length of 2180mm and a distance between centres of 1900mm. It was equipped with an 80mm spindle bore, making it highly versatile for a wide range of bar work.
