Designed specifically for manufacturers and subcontractors that demand the utmost in machining flexibility and the capability of processing precision complex parts, Kitamura has launched the Mytrunnion 4G.
This powerhouse 5-axis machining centre ensures the highest level of precision with unbeatable accuracy levels of +/-0.002mm and a repeatability of +/-0.001mm. For customers that require precision coupled with speed and rigidity for machining small to medium components, this unparalleled level of precision is achieved by hand-scraping of all major sub-assemblies, coupled with linear scale feedback on all axes.
The new Mytrunnion 4G from Kitamura has a maximum work-piece diameter of 500mm on its rotary trunnion table and 400mm work height in the Z-axis, with the ability to accept billets up to 200kg. This ultra-high precision, simultaneous 5-axis machine has a tilting table that rotates -120 to +30 degrees in the A axis, with a C-axis rotation of 360 degrees, both having a minimum indexing command of 0.001 degree.
The design of the Kitamura trunnion table delivers incomparable stiffness and rigidity that provides the ability to position the work-piece very close to the spindle for optimum machining performance. To carry most of the machining load it employs a trunnion type cylinder in the A-axis supported by double column bridge, with both sides of the cylinder system mounted squarely against the centre of the C-axis, thus offering a higher level of rigidity and accuracy. The Mytrunnion 4G uses a high precision roller gear cam mechanism in the 4th & 5th axes that further enhances the in-built zero-backlash capability of the machine.
This rigid machine design enables the powerful 15kW directly driven spindle, with a BT40 taper (HSK63 optional), to maximise material removal rates. With the world’s fastest accelerating spindle, the Mytrunnion 4G gets to a maximum speed of 15,000rpm in just 2.3 seconds. The machine comes with a 50 tool carousel as standard and the motor, spindle and tool change mechanism have all been designed to provide a performance level that exceeds competitive machines in its class.
The 9000kg machine has a compact 3.7M by 2.2M footprint that provides a compact powerful machine package, further enhanced by the efficient Kitamura Arumatik-Mi CNC control. This user friendly control system, driven by a high speed Mitsubishi processor and with its large 19 inch LCD screen, includes multi work setting displays, maintenance support functions, in-built diagnostics and video guidance, making the Arumatik-Mi the most innovative, feature rich and user friendly control unit available.
Coupled with engineering and applications support, this Kitamura machine / control combination is unique in that it provides the operator with a practical, user friendly work station. The super-fast and smooth data processing, quality of build and enhanced machine features all give the user the confidence of machining complex work-pieces in an efficient and cost effective manner.
