Custom Made Machines

We were approached by a Medical Company producing .3mm dia needles, they wanted to grind a quantity of 200 at a time, with a main bevel point of exactly 82 degrees, and a secondary angle of 78 degrees, with a pencil point on the other end.

We used a 20 year old Jones & Shipman series 10, totally gutted the machine and used only the basic carcass and wheelhead. We then added new ball screws powered by Fanuc motors and drives, we built a special tilting fixture again powered by Two Fanuc motors which not only tilted to give us the angles required but also rolled the needles backwards and forwards to grind the point.

This customer wanted to update their existing manual machine to CNC. Their application was to cut glass slices from a tube which needed to be parallell and accurate in thickness.

We gutted their existing machine, ground all slideways and replaced all internal items with ball screws and servo drives. A new Fanuc CNC control was fitted and programmed for all operations.

To retrofit customers existing machine to produce components faster with more accurate repeatability.

Their WMW Internal grinder was completely dismantled and all hydraulic parts discarded and replaced with ball screws and servo drives giving the machine thermal stability. A new Fanuc CNC control system fitted with programmed cycles.

Our customer required several machines to grind the internal bore of minature collets used for drilling in the production of printed circuit boards. The collet and drill rotates at 500,000 rpm so concentricity is vital, an off the shelf machine was not available.

We took an old Jones & Shipman Model 1070 machine and replaced all internal components with ball screws and servo drives, a new CNC control was fitted and programmed to the customers needs. A special swiveling workhead was designed to grind both parallel and tapered bores.

This customers requirements was to grind quartz cylinders of 600mm diameter, they also wanted to grind a series of slots along the front face.

We took a Studer CNC cylindrical grinder and raised the centre height. We then fitted a precision internal spindle at right angles to the wheelhead to grind the slots. The machine was fitted with a Fanuc CNC system and programmed to grind the diameter and slots in one continuous operation.
