Mills CNC, the exclusive distributor of DN Solutions’ machine tools in the UK and Ireland, has introduced a next-generation, high-productivity horizontal machining centre. The new twin-pallet NHP 5500 represents a significant upgrade on its predecessor, and boasts faster acceleration/deceleration rates, improved tool change times, enhanced thermal compensation and faster B-axis table rotation.
DN Solutions’ NHP 5500 features acceleration/deceleration rates in X, Y and Z of 0.91G, 1.07G and 1.02 G respectively which, combined with its 60 m/min rapid rates, delivers faster processing speeds and a reduction in non-cutting times: all essential in ensuring higher productivity and process efficiency.
The focus on improving productivity is also evident with the machine’s faster tool change times. Equipped with a generous sized servo-driven ATC (from 40 up to 376 tools depending on the tool magazine selected), tool change times are 1.7 seconds (T-T-T) and 4. 7 seconds (C-T-C).
Notably, the NHP 5500 is equipped with a built-in 37 kW/10,000 rpm BT50 spindle with integrated smart thermal compensation sensor technology, This, combined with the machine’s spindle (oil-cooled) cooling system, reduces thermal displacement and ensures high part accuracy and repeatability, even during heavy-duty machining and long periods of operation.
The NHP 5500 has a rotary shuttle-type, twin-pallet configuration with a pallet-change time of 12 seconds. In addition to fast B-axis indexing (1.1 seconds for 90°, and 1.5 seconds for 180°), this capability enables customers to achieve higher productivity. The integration of a cone air blower that injects high pressure air into the location cones which connect the pallet to the table, removes chips from surfaces, resulting in accurate pallet positioning and improved process reliability.
