Kitamura Machinery has introduced the Mytrunnion-5G 5-axis vertical machining center (VMC), further expanding its Mytrunnion 5-axis lineup. The Mytrunnion-5G has been mechanically and electronically designed specifically for speed, rigidity and flexibility in complex 5-axis machining.
Features include:
- Induction hardened solid box way construction offers the vibration damping properties necessary for fine surface finishes.
- The A-axis fully integrated trunnion table (-120 to +30°) is driven by a high precision worm wheel and shaft for enhanced stiffness and stability.
- A standard 20~20,000 RPM #40, 4-step gear-driven dual-contact spindle delivers strong low-end torque and high-end fine finish capability for enhanced machining flexibility. The 20 HP/AC spindle motor offers max. cutting torque of 201.4 ft-lbs. An efficient oil chiller system minimizes thermal displacement and maximizes spindle life to achieve high-speed, high-accuracy 5-axis machining.
- Dynamic double column construction allows the Y-axis to be fully supported throughout its entire movement, full stroke.
- The rigidity of Kitamura's patented triangular cross rail driven by twin fine pitch ballscrews is engineered to evenly distribute headstock weight and cutting forces for chatter-free machining and enhanced accuracy and surface finish.
The Mytrunnion-5G offers an extra-large work envelope of O630 mm (O24.8") x 500 mm (19.7") high and a table load capacity of 400 kg (880 lbs.) with a sliding ceiling cover for easier load and unload of medium to larger size parts.
A standard, feature-rich high precision package includes positioning accuracies of ±0.001 mm (±0.000039")/full stroke and repeatability of ±0.0005 mm (±0.00002"), a built-in, rigid trunnion-style tilting table, ballscrew cooling, Heidenhein linear and rotary scale feedback in X, Y, Z, 4th and 5th axes and Kitamura's IAC System 1 thermal compensation system to control the effects of heat displacement to help ensure continuous accuracy in machining.
The Mytrunnion-5G has a standard 50-tool high speed ATC with an optional 100T upgrade available as a field installed option. "A standard double decker style chip conveyor and filtration system, 220 PSI coolant through the spindle and base wash and overhead wash shower coolant offer high-end excellence in chip evacuation filtration to 100 microns," said a company spokesperson.
Ideal for 5-axis machining, Kitamura's Arumatik-Mi Control offers 1,680 block look-ahead and fast, smooth processing speeds of 2,800 blocks/sec. for faster machining of more complex workpieces. A completely customizable icon-driven touchscreen offers a user-friendly expandable control environment for the operator. Standard features such as remote monitoring screens, on-demand "HELP" guidance, visual work setting, tool breakage detection, free software upgrades throughout the life of the control, and collision safety functions all work in tandem to monitor machine performance and help ensure uptime.
