EDM for oil and aerospace
David Light says the CUT 300 machines are able to machine a wide spectrum of parts – from simple through to complex
Portsmouth subcontractor Di-Spark has increased its capacity by investing in two wire EDM machines and a fully automated spark EDM machine.
The Agie Charmilles wire EDM machines are being used on a range of complex high precision parts, especially for a customer in the oil and gas sector. The spark EDM machine has been integrated in an autonomous cell for an aerospace customer.
Di-Spark’s managing director David Light says: “Our existing wire EDM machines, whilst still performing satisfactorily, had a finite capacity. Owing to us winning new contracts and having existing contracts extended, we realised that we would be soon hitting a capacity problem. We needed to address the situation and the decision to invest in new advanced wire EDM technology was made.”
He adds: “The CUT 300 machines are able to machine a wide spectrum of parts – from simple through to complex.
The decision to invest in the FORM 2000 spark EDM machine with integrated automation follows on from a contract that the company won from a leading aerospace OEM three years ago.
David Light says: “Owing to the quality of the parts that we’ve produced, our modern machining methods and our cost-competitiveness we’ve managed to secure more and more work from this customer – which is great news. However, the downside was that the increased demand was putting a strain on our existing spark erosion capabilities.”
The company therefore decided to create a dedicated, self-contained manufacturing cell for this customer, at the centre of which will be the FORM 2000. The cell also features a System 3R work-piece pallet and electrode changer, a 5-axis milling machine and a wire EDM machine. It can operate unmanned, including overnight and at weekends, and has helped Di-Spark dramatically increase its productivity and efficiency.
The aerospace customer has recently used Di-Spark as a reference site, having a number of its own internal design and quality engineers visit the facility to find out more about Di-Spark’s advanced manufacturing facilities. Di-Spark has also been put onto the customer’s Supplier Development Program with the objective of achieving Master Supplier status.
