United Grinding Technologies, Inc. (UGT)
announces the introduction of a new addition to its Studer line of
high-performance cylindrical grinders, the eco1000CNC.
Modular design for quick setup and changeover, state-of-the-art digital control and drive systems and user-friendly step-by-step programming make the eco1000CNC a flexible solution to a wide variety of external cylindrical grinding applications, especially long, shaft-type workpieces. Center height is 175mm. Between centers grinding length is a full 1000mm. Wheel size: ø 500mm x 80mm x ø 203.8mm. Chuck capacity between centers is 80 kg. The right-side wheelhead is orientable from 0° to 30° for straight and angular plunge grinding.
Digital direct-drive, three-phase servo motors with 40mm diameter prestressed, precision ballscrews power the X-and Z axes. Cross slide X-axis travel is 285mm at speeds ranging to 5,000mm/min. Linear resolution is 0.0001mm. Distance between slideways is 280mm. Z-axis slide travel is 800mm. Speed and linear resolution are respectively 10,000mm/min and 0.0001mm. Z-axis distance between slideways is 200mm. Z-axis table tilts up to 8.5° for high-precision grinding of tapers.
Cast iron V and flat guideways are cast directly into the machine base and are coated with abrasion-proof Granitan S200 to provide high vibration dampening and rigidity. According to a company spokesman, a patented guideway design prevents hydrodynamic effects found in conventional guideways and results in high load-bearing over the entire machine. The machine base of Studer-developed Granitan S103 delivers chemical stability and thermal compensation.
The grinding spindle is powered by a 7.5 kW motor and has high-precision roller bearings for high-resistance, maintenance-free operation. Peripheral speed-up is to 45m/sec. The workpiece spindle handles grinding between dead centers as well as live grinding with revolving spindle. A precision control permits fine adjustment of cylindricity during grinding operations to +/- 40 µm. Guaranteed tolerance precision: 0.0004mm on roundness and 0.0025mm straightness deviation over a length of 650mm.
