The CT960 universal internal grinding machine from United Grinding features a fully interpolating B axis and four spindles for complex grinding tasks. It is suitable for machining small- to medium-sized parts including die plates, spring collets, toolholding fixtures, hydraulic components, medical components and thread ring gages in materials including tool steel, tungsten carbide, ceramic and glass.
The grinding spindle turret features a dynamic direct drive said to enable faster swiveling times. Workpieces can be completely machined in the same clamping. The swiveling time is less than 2 sec. for 90 degrees, and less than 3 sec. for 270 degrees. The angular position of the grinding spindles is infinitely variable from -5 degrees to +30 degrees in all four positions. The automatic B axis of the workhead features a swiveling range of +61 to -91 degrees. The B axis has no contact surface, and is completely closed and virtually wear-free. A coolant distributor is designed to ensure well-regulated internal conditions. Studer SimCT software performs indexing functions.
