This Jones & Shipman Progrind 1267 is a grinding machine — sometimes referred to as a surface grinder — built to remove material from workpieces with precision, producing flat, contoured, or profiled surfaces to tight tolerances. Jones & Shipman is a long-established British manufacturer with a strong reputation in precision grinding technology, supplying machines to toolmaking, aerospace, automotive, and general engineering industries.
This example was built in 2006 and is offered used from a seller in Belgium. The machine is equipped with a Fanuc touchscreen control system, giving the operator a modern, programmable interface for managing grinding cycles. A Nikken fourth axis is included, extending the machine's capability to index or rotate workpieces and enabling more complex grinding operations beyond simple flat work.
The table measures 1,200 × 600 mm and offers a longitudinal travel of 1,610 mm under manual operation or 1,420 mm under hydraulic drive. Transverse movement is 750 mm, and vertical movement reaches 850 mm. The maximum distance between the table surface and the grinding wheel is also 750 mm, defining the effective working envelope for taller workpieces.
The grinding wheel accommodates a maximum diameter of 457 mm with a width of 100 mm and a bore of 203.2 mm. Spindle speeds are selectable at 1,400 rpm or up to 3,000 rpm, allowing the operator to match surface speed to the wheel specification and the material being ground.
Also included is a twin rotary diamond disc dressing unit, mounted vertically with a slideway adjustment to accommodate differing grind heights. The unit is designed to carry twin opposing diamond discs, supporting dressing in both directions and maintaining the 6-thou diamond tip radius, which helps preserve consistent wheel profile across extended production runs.
