Internal Cylindrical Grinding Machine

With the recent addition of the Studer CT internal cylindrical grinding machine series, United Grinding has substantially increased their ID grinding capabilities. UGT’s wide range of ID grinding machines now includes 8 Studer CT machines as well as the Studer S120, S145, and S151. This innovative ID grinding product line is complemented by the Studer S33 and favoritCNC, both of which feature ID and OD grinding but are configured by many customers as dedicated production ID grinding machines. The complete lineup offers a solution for workpieces of all sizes, shapes, and materials.

Small Bore Agility
Studer’s S120 features a compact footprint, cross-slide design for up to 2 internal grinding spindles, easy automation, C-axis, a large selection of multi-application spindles, and modular configurability, making this machine ideal for applications like carbon sleeves, hydraulic valve components, fuel injector parts and other small precision components.

Universal Appeal
The Studer S145 is perfect for the machining of medium-sized workpieces up to 200mm (7.9”). This machine is especially suited for workshops producing prototypes and small runs or those involved in toolmaking. With the appropriate configuration, the S145 can also function as an efficient production machine. High precision tooling, bearings, gears, and mold components are ideal applications for this machine. Its modular design, easy programming, and optional C-axis for form and thread grinding make the S145 an indispensable part of your shop floor.

Large, Complex Workpieces
The powerful Studer S151 grinds workpieces up to 300mm (11.8”) in diameter. The substantial accommodation capacity of the sturdy workhead and spindle turret with up to 4 grinding spindles offer a wide variety of application possibilities and are suitable for complete machining in one setup. Parts like turbine rotors and vanes, gears, and automotive transmission components are handled with ease on the S151.

Spring Collets to Can Dies, Ceramics to Carbide
Studer’s CT product line is ideal for small- to medium-sized internal cylindrical grinding applications such as die plates, spring collets, tool holding fixtures, hydraulic components, and thread ring gauges composed of hard materials like tool steel, carbide, ceramics and glass. The modular and flexible arrangement of spindles enables optimal dimensioning of the machine, ranging from the machining of individual parts to large-scale production. Studer CT machines also support integrated and autonomous loading systems for added flexibility and increased efficiency.
