ATC, a large worktable (1000mm x 450mm) with a 600kg maximum load, and features the advanced Fanuc 0iMP control with a 15” touchscreen iHMI. The DNM 4500 has a rigid-design and build as well as roller-type LM guideways which, along with its integrated thermal compensation systems, ensure high accuracies and repeatability’s - even during long periods of operation. Fast rapid rates (36m/min) and quick tool change times (1.2 seconds tool-to-tool) guarantee fast part processing and, as a result, higher productivity, improved efficiencies and reduced lead times. To help realise the machine’s productivity potential and optimise performance, the machine was supplied, as part of the investment package, with though-spindle coolant capability (20bar) and a Nikken CNC 202 (4th-axis) rotary table for fast and accurate part indexing. The company further augmented its machine tool purchase by investing in a precise, flexible and expandable work-holding system (comprising plates, vices, clamps) from Micro-Loc that enables quick job set-ups and changeovers and the machining of large and/or multiple smaller parts. The DNM 4500 has, as was intended, significantly increased the company’s machining capacity and capabilities. “We needed a fast, accurate and competitively-priced machining centre, and with the DNM 4500, that’s exactly what we have got.” Concludes John Watts. n
“In order to maintain these supply chain relationships, we needed to strengthen our in-house milling capabilities by investing in a reliable, high-performance production- oriented machine that would meet our, and our customers, immediate and future requirements.” As a consequence, the company drew up a detailed specification checklist for its new machine tool investment with a number of ‘must haves’ which included: a Fanuc CNC control to ensure the quick and easy transfer of parts and programs between the new machine and its previously acquired DNM 500 II machining centre. A large machining envelope to enable the machining of large and/or smaller, multiple parts in a single set-up. A powerful spindle capable of machining a range of different materials, and delivering fast part processing speeds. A reliable, versatile and proven machine with an established track record twinned with Quick availability and a competitive price and a proactive after-sales services provided by the machine tool supplier. John Watts Continues “As an existing Doosan user, we have good relationships with Mills CNC. We like their business approach and the three Doosan machines we had from them in the past have all performed well and haven’t missed a beat. “It therefore made sense to contact Mills and, having discussed our needs and requirements with them and seen a DNM 4500 in action at their showroom facility in Leamington, it was a ‘cut and dried’ decision. About the DNM 4500 The DNM 4500 is a powerful, precise, flexible and reliable 3-axis machining centre. The machine supplied to the company is equipped with an 18.5kW/ 12,000rpm (BT 40) direct-drive spindle, a 30-tool position
