Travelling-column machine with Siemens CNC

The latest machine from Yamazaki Mazak to feature a Siemens CNC is its VTC-760C vertical travelling-column machining centre, which is controlled by the 828D.

Based on a dual-load configuration, the machine benefits from a compact footprint, as well as a long X-axis stroke and 2300 mm fixed table. Also featured is a 12,000 rpm spindle and rapid traverse rates of 42 m/min in the X, Y and Z axes.
The inclusion of the Siemens control represents an entry into the commodity market, as the 828D is viewed as a mid-range CNC for turning and milling machines. A 15.6” touch-screen display runs on Sinumerk Operate 4.7 and features a built-in keyboard with USB and ethernet interfaces.
A number of intelligent operations underpin the CNC, including ShopMill, which automatically compiles machining step programs to enable multiple clamping operations with fewer tool changes. A built-in maintenance planner is also included.
The control communicates in over 20 languages and can be programmed to send SMS messages to operators, machine setters, or service and maintenance technicians, providing alerts for tool life, availability of blanks and upcoming maintenance schedules. Importantly, the control is also able to provide automatic feedback on a range of machine diagnostics.
Similarly, the VTC-800/20SR, on which Mazak has offered the Siemens 840D sl control since 2013, is now the first company machine to feature the new style of control panel. Comprising a 19” touch screen, the latest control panel can be tilted and rotated to offer improved operator ergonomics. As with the 828D, the 840D sl runs on Sinumerik Operate 4.7 and is able to provide users with a number of connectivity and diagnostic functions.
