Following the introduction and success of the UMC-5X we had many conversations with customers who, while seeing the advantages of simultaneous five-axis movement, couldn’t justify the investment. This led directly to the creation of the UMC 4+1, which at a starting price of under £130,000, which is a saving of around £30,000 over the UMC-5X, providing a highly cost competitive entry into five-axis machining for those not requiring simultaneous five-axis operation.
The XYZ UMC 4+1 shares the same machining envelope as the UMC-5X, with axis travels of 600 by 600 by 500 mm (XYZ) and a 600 mm trunnion-style rotary table that has 90 revs/min rotational speed and 600 kg load capacity. Customers can choose from either a 12,000 or 15,000 revs/min in-line spindle or a motorised unit with up to 24,000 revs/min. Control is provided by the popular Siemens 828D Shopmill system with its 15” touchscreen interface.
