Page 62 of 67 61 September 10-15, 2018 / Chicago, IL Five-Axis Horizontal Machining Cell Carries 174 Tools Kitamura Machinery's five-axis Supercell-300G horizontal manufacturing cell features a 20-station automatic pallet changer (APC) with work ID system and a 174-tool, matrix-style toolchanger. The Supercell-300G can run small- to medium-size parts completely unattended. The cell's integrated work ID system employs an IC chip on each pallet, enabling storage and communication of pallet work data to the pallet scheduling submenu. Pallet table size is 200 mm (7.9") in diameter, with a maximum height of 200 mm (7.9"). The integrated design of the pallet pool system enables access to and visibility of all pallets simultaneously. The cell's automatic work handling robot reduces pallet load and unload times and facilitates just-in-time production of a varied mix of parts. The machine's 360-degree rotary table tilts 30 to 120 degrees on an A-axis trunnion. The fourth and fifth axes employ precision roller gear cam technolo- gy, along with a hydraulic clamping system designed for five-axis simultaneous machining. The 20,000-rpm, dual-contact spindle is designed to handle exotic materials common to the aerospace and medical industries. The 174-tool, matrix-style toolchanger magazine (up to 314 tools available) handles tools up to 350 mm (13.7") in length, 150 mm (5.9") in diameter and 10 kg (22 lbs) in weight. Tool-change time is 1.3 seconds. Compared to a vertical spindle configuration, a horizontal design improves rigidity and workpiece accessibility and chip management. Better chip management translates to improved accuracy, surface finish, part change-over time and tool life. Kitamura Machinery of USA Inc., South Level 3, Booth 339148 EDM Drill Provides High Production, Unattended Operation Current EDM Inc.'s FT300 five-axis CNC EDM drilling machine features the Siemens 840Dsl control. The fully enclosed machine is designed for produc- tion facilities in which machines are placed side-by-side in rows. It is operable and serviceable from both the front and rear machine panels. Moving-gantry design and a stationary worktable increase weight capacity and reduce opera- tor reach for ergonomic part handling. The machine suits high-tolerance work in the aerospace, medical, automo- tive and cutting-tool industries. Table travels are 12" on the X axis and 6" on the Y axis, with a part-weight capacity of 30 lbs at the tilt-rotary table. Precision slides and a 6" diameter, 10" high cylindrical work envelope enable accurate positioning and drilling of complex parts such as turbine engine components, nozzles, valves, injectors, medical/dental devices and cutting tools. Drilling aspect ratios greater than 300:1 can be achieved with DI water. The machine features a 24-station electrode changer for high production and unmanned operation. EDM milling expands capabilities by enabling the machining of three-dimensional shapes such as gates and diffusers. A sensitive servo and finely tuned power supply enable the machine to drill with consistent speed, wear and depth control. It won't bend or collapse long, thin electrodes, and exit-hole break-through speed is optimized for rapid hole-to-hole cycle time. Current EDM Inc., East, Level 3, Booth 135051
