Precision component from 3mm diameter – 200mm diameter and up to 1m in length
We offer make-complete or grind-only services to suit your project. Our manual grinding processes deliver high accuracy with an optimised smooth finish. Heat treatments often create distortion to the surface of a component, our various manual grinding options remove imperfections and finish to a parallel surface.

Manual surface grinding is used to produce a smooth finish to flat work pieces. Accurate thicknesses, step-down features and precise parallelism can be achieved.
Typical end-products include spacers, slugs, shims and guides. On smaller components we can grind multiple pieces simultaneously to produce perfectly matched components.
We surface grind hardened steel work pieces to remove the distortion that can occur following heat treatment.
Diaform grinding creates the shape from the grinding wheel which is then plunge ground into the component. Complex shapes can be achieved in one pass. Examples are grinding serrations to form a cutting blade, form tools and other custom tooling applications.
Cylindrical grinding process enables the creation of external spherical forms. We grind one diameter at a time, measure and check at each stage. This process is best suited for small-batch work with critical precision and a high quality of finish.
We currently operate three Jones & Shipman toolroom and production grinders.
High speed internal manual grinding at 60,000rpm. Punches for really small diameter holes. Grinding bores on 3D-printer components down to approx 1mm.
Centreless grinding is the ideal machining process for small batch to higher volume orders. This method of manual grinding is used when it is not possible to hold the component between the centres. It offers a fast and accurate finish.
This process uses a through-feed and will grind and straighten lengths of bar, shafts or dowels in a linear form.
The grinding wheel is in continuous contact at a single point of contact with the component. Used for objects that are not uniform, for example a bar with a head at the end.
