For highly productive machining, Leader CNC has now introduced the compact new Kitamura 3XD vertical machining centre. The innovative new machining centre has been developed with a large work envelope that is packed into a small footprint for machine shops with limited floor-space.
Kitamura has built this machine upon a C-Frame base to maximise rigidity and vibration damping with heavy duty cross roller linear guideways to further enhance performance and retain Kitamura's renowned levels of precision. Whilst the combination of a robust built quality and small footprint may be appealing to manufacturers, the productivity of the 3XD and innovation packed into the Arumatik-JR CNC control really set this machine apart from anything else in its class.
The high powered 3XD is the ideal productivity partner for manufacturers in the mould & die and general subcontract markets. With an X, Y and Z-axis travel of 760 by 510 by 510mm that is covered by a high powered 26kW spindle that can travel at rapid rates of 48m/min, the 3XD epitomises power and productivity. To support high material removal rates, the 3XD incorporates a 40NST spindle taper and a maximum spindle speed of 12,000rpm.
The dual contact spindle is supplied tools by a 24 tool magazine with a random memory selection that provides an astounding tool change time of 1.9 seconds. This reduces non-cutting times significantly whereas the spindle taper can accommodate maximum tool diameters of 75mm with a tool length of 240mm. The capacity for large tools, unparalleled tool change times and a high powered spindle motor, all combine to give the 3XD productivity rates that cannot be matched by any other machine of its size.
All this is driven by Kitamura's state-of-the-art Arumatic-JR CNC control unit that is packed with high speed machining functions that are beyond the realms of alternate control units. The feature rich Arumatic-JR provides processing speeds 16 times faster than alternate controls. Some of these features include a 675 bock look-ahead, USB and Ethernet interface for fast and smooth program transfer. As standard, the new Arumatic-JR control on the 3XD has workpiece co-ordinate system (54 sets), co-ordinate system rotation, 700 custom macro variables, inverse time feed, 400 tool offset pairs, 3D tool radius compensation, high speed skip, thread cutting, rigid tapping, small diameter deep hole drilling and tapping cycles, helical interpolation and much more. This innovative CNC control unit is packed into a intuitive user friendly platform that permits programming speeds that are inconceivable from alternate control units.
The robust machine platform, linear guideways, high powered spindle and rapid feed rates make this machine the outstanding performer in its class. With this culmination of features being driven by a unique CNC control, Leader CNC truly leads the industry with this high performance machine for small to medium sized components. With such high productivity rates, swarf evacuation is a critical factor and with the 3XD, Kitamura offers a flexible configuration that allows the end user to place the conveyor on either the left or right of the machine.
