ncorporating a new-type spindle unitA high-efficiency motor with an output of 5.5/7 kW is adopted as the built-in motor. The unit is compatible with chucks up to 4 inches, and a hydraulic cylinder can also be equipped as an option to enable stable mass production machining of workpieces that require a strong gripping force. The reviewed cooling circuit has made the oil controller that used to be essential for short-cycle machining unnecessary*, reducing the cost and space requirements.
* An oil controller is still required with some specifications.
Pursuing high precision cutting by incorporating a cooling system in the machineGenerally on a machine with 2 spindles, a heat imbalance arises in cases where different cutting is performed at the left and right sides. This leads to unstable accuracy. The XW-30 series is built with a cooling tank inside the bed for the two spindles to suppress thermal displacement, achieving stable accuracy over the long term (patented).
Space-saving design and long-awaited addition of CE specificationsSpace savings have been realized with a machine 1,340 mm wide (bed width: 1,040 mm), 2,120 mm deep and 1,500 mm high. Compliance with CE standards has been made possible too, enabling safe usage in Europe as well.
* Machines with CE specifications have different dimensions.
