Kitamura Machinery launched the revolutionary 5-axis Mytrunnion 1 machining centre at the recent IMTS exhibition, Chicago, in September. It is capable of machining, turning and grinding complex components.
Equipped with an upgraded Fanuc 300iS control, the Mytrunnion 1 has been designed not only for high speed 5-axis machining, it can also turn components at 1,000 rpm. The machine also combines an optional 30,000 rpm spindle speed with the rotary table for grinding operations. The Mytrunnion 1 has a fast tool-to-tool time of 1.1 seconds that works with a 60- position ATC as standard.
The Mytrunnion 1 is ideal for medical parts, aerospace components, and similar complex parts up to 350 mm in diameter and 215 mm high. Cooled ballscrews and scales are fitted as standard to achieve and maintain the extremely high accuracy. The machine at IMTS was fitted with a 20 pallet system to exhibit the Mytrunnion’s capability to comfortably fit into a volume production or unmanned running environment.
For 5-axis machining, the Mytrunnion 1 uses an a-axis tilting trunnion fitted with an integral full rotary c-axis having a rotational speed of 1,000 rpm. The machine is also capable of heavy duty cutting. This is provided by its hardened and ground box ways that have a dampening effect seven times greater than linear guide ways. When combined with the high spindle torque, the Mytrunnion has a removal rate of 240 cm³/min in S50C steel.
At under 7M², the Mytrunnion 1 has been designed to take up less floor space.
