The Ultramat 1000 CNC B universal grinder includes a variable rotating B axis and Renishaw probing

Produmax has purchased a Jones & Shipman (J&S) Ultramat 1000 CNC B universal grinder to give it a range of new grinding options and reduce manufacturing cycle times on several components.

The acquisition of the Ultramat, which replaces three older J&S machines, plays a significant role in the delivery of one of Produmax’s larger contracts - the manufacture and assembly of wing flap actuators for Bombardier.

The actuator assembly contains a number of components where concentricity and a good seal between surfaces is essential for unblemished operation and, West Yorkshire-based Produmax says the Ultramat has reduced the cycle times from 25 minutes to around five.

Produmax operations director, Paul Birtles, commented: “Having a machine with such capability and capacity means the technical team are continually finding new projects for it in addition to those we had initially allocated on its installation. This has given us greater flexibility when reviewing methods of manufacture.

“Also, while the 1000mm grinding length capacity is more than adequate, with new applications coming in all the time, having a ‘future proofed’ machine is a real bonus.”

The grinder is highly specialised with a variable rotating B axis, Renishaw probing, Heidenhain ‘Absolute’ linear scales, a full Fanuc 0i CNC and J&S’s own software to minimise set up times and maximise output.

Workpiece materials vary but are aligned within the grinder’s capabilities, as Mr Birtles explains: “Our expertise in high precision engineering and knowledge of machining processes embraces hardened and PH steels, titanium, Inconel and aircraft grade aluminium alloys as well as heat treated and hard chromed materials and this enables us to manufacture difficult to make components with volumes ranging from small batch work to large multiples.”

Produmax is also producing significant numbers of components destined for installation on the latest C series aircraft which is being assembled by Bombardier factories around the world; quite a few of these components are hard chromed and ground using the grinder.

Produmax Limited has recently become the first company outside of the USA to achieve the latest AS 9100 revision D quality standard and the first company globally to be accredited to prEN 9100:2016.
