Surface grinder creates big impact at small component specialist

Since installing a Jones & Shipman 524 EASY surface grinder, Micrometric Ltd – the Lincoln based small laser cut components specialist – has been able to broaden its horizons in terms of component manufacturing capability while greatly improving its customer response times. Previously reliant on subcontractors for its grinding operations, Micrometric decided that a combination of changes at its supplier plus an increasing volume of components needing ground profiles and surfaces justified investing in its own grinding machine. “It was not a technique we had first hand experience of” explains managing director Neil Main, “but one of our production engineering team had worked in a grinding environment and suggested Jones & Shipman as a start point. We approached them and received a solution that meant we did not look any further,” he explains. Micrometrics-PR1B“Small and precise” is Neil Main’s description of Micrometrics’ expertise. “A high proportion are laser cut components supplied to end users ranging from energy to automotive with an increasing percentage into aerospace where Micrometric holds the all important AS9100 accreditation. The common denominator throughout its customer base is the small size of componentry. “It’s where we started (in 1982) and we are now one of about half a dozen UK companies specialising in small and micro component development and manufacture,” Mr Main adds. This is reflected in the choice of J&S grinder. A machine with a grinding bed capacity of 500mm (long) x 200mm (wide), from Micrometric’s viewpoint it importantly features the unique J&S developed EASY programming software that according the Neil Main, lives up to its name in every sense. “Production runs can be anything from 10 to 10,000 but typically 250 is an average batch size. That is well within the machines capacity but more importantly, the inventory of parts we manufacture is vast. We store the programmes on an adjacent PC and our operators can rapidly call them off when a batch – or even a one off – is required. With the EASY software, this is proving to be a simple and reliable operation with repeatability the all important necessity.” The 524 machine has been developed by Jones & Shipman to cater for a wide range of installations from toolroom to batch production environments using manual, semi or fully automatic machining modes. Features such as main castings, slideways and the wheel head assembly offer rigid construction with high precision geometry, while the Y and Z axes are controlled and positioned by Fanuc digital AC motors with Heidenheim Absolute linear nano feedback for ultimate control of the axes and grinding process. Micrometrics-PR2AThe EASY touchscreen control offers the operator the benefits of CNC control without the complexity of a traditional CNC system.
EASY is icon based software that can interpolate two axes simultaneously to enable precision output of complex shapes, angles, profiles and surfaces. Its self teach capability allows both experienced and inexperienced operators to rapidly grasp the features and quickly become productive. At start up the operator is offered a choice of three modes – manual, dress or grind – and having made his choice a range of options are automatically presented that enable productive operation in the shortest possible time. Micrometric also prides itself on the range of workpiece materials it can work with – stainless and nickel alloys are commonplace but also molybdenum and tungsten steels are typical – and they have optimised their use of grinding wheels to suit. They have also made all their own jigs, fixtures and tooling – some using the 524 EASY – and this has proved both cost effective and beneficial to productivity. “Starting from scratch was a bonus in this sense,” adds Neil Main. “We were able to establish priorities and manufacture fixtures precisely to suit our customer component options. This has greatly reduced downtime and given us a significantly improved ability to respond, especially to urgent batch requirements.Micrometrics-PR-3-4A “The J&S machine has easily integrated into our operations and almost on a daily basis we are realising the benefits and flexibility of having our own, in house capability. In the 2 months we have had the unit we have made significant strides in paying back our investment,” he concludes.
