Kitamura's Five-Axis Machining Center Promotes Accuracy
Kitamura’s Mytrunnion-5G five-axis vertical machining center is designed for maximum accuracy in and capability for complex five-axis machining.
Kitamura Machinery has expanded its Mytrunnion five-axis lineup with the Mytrunnion-5G five-axis vertical machining center. This machining center focuses on speed, rigidity and flexibility in complex 5-axis machining.
The Mytrunnion-5G’s induction-hardened solid box way construction dampens vibrations, while the dynamic double column construction supports the Y-axis throughout its entire movement. A high-precision worm wheel and shaft drive the A-axis fully integrated trunnion table (-120 to +30 degrees), which the company says benefits stiffness and stability. A standard 20-20,000 rpm #40, four-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’s maximum cutting torque is 201.4 foot-pounds, and an efficient oil chiller system minimizes thermal displacement and maximizes spindle life. Kitamura’s patented triangular cross rail evenly distributes headstock weight and cutting forces for chatter-free machining, improving accuracy and surface finish.
The Mytrunnion-5G’s work envelope measures 630 mm (24.8”) x 500 mm (19.7”), with a table load capacity of 400 kg (880 lbs) and a sliding ceiling cover to improve access for medium to large parts.
A standard, high-precision package includes positioning accuracies of ±0.001 mm (±0.000039”) with full stroke and repeatability ±0.0005 mm (±0.00002”); a built-in trunnion-style tilting table; ballscrew cooling; Heidenhein linear and rotary scale feedback in the X, Y, Z, fourth and fifth axes; and Kitamura’s IAC System 1 thermal compensation system to control the effects of heat displacement and ensure continuous machining accuracy.
A standard double-decker chip conveyor and filtration system, 220 psi coolant through the spindle and base wash and overhead wash shower coolant provide chip evacuation filtration to 100 microns.
Kitamura’s Arumatik-Mi Control offers 1,680-block lookahead and processing speeds of 2,800 blocks per second for faster machining of more complex workpieces. A customizable, icon-driven touch screen offers a user-friendly, expandable control environment.
All around the world, companies that machine molds and dies face numerous challenges as well as numerous opportunities. How these companies are responding are influencing the entire metalworking industry.
