Internal / Universal Cylindrical Grinder Increases Shop Capabilities

The Studer CT550 from United Grinding Technologies is ideal for small- to medium-sized internal cylindrical grinding of die plates, spring collets, tool holding fixtures, hydraulic components, and thread ring gauges composed of hard materials like tool steel, carbide, ceramics and glass. 

With the recent addition of the Studer CT internal cylindrical grinding machine series, United Grinding Technologies, Inc. (Miamisburg, OH) has substantially increased their ID grinding capabilities.

In the area of internal grinding of chucking components, the Studer CT550 sets new standards. Higher precision, better surface quality, high metal removal rates – in addressing these requirements, UGT has again set the standard with its new CT550 CNC internal/universal cylindrical grinder.

It works more quickly and precisely, offers a broader range of applications, with production options that are highly attractive with regard to cost-effectiveness. By saving on auxiliary times, the CT550 considerably shortens the cycle times of the grinding process.

The CT550 is a compact machine for medium-sized workpieces with up to three inline grinding spindles. The modular and flexible arrangement of spindles enables optimal dimensioning of the machine, ranging from the manufacture of individual parts as well as large-scale production. This machine also supports integrated and autonomous loading system.

The Granitan® S103 machine bed provides a very solid, rigid and thermally stable CT550. The formula of this mineral casting is designed for optimal grinding operation conditions. Thus, the machine bed literally provides the integrated guide system with a stable basis for absorbing the high forces that occur during grinding.

Thanks to its remarkable thermal behavior, the machine bed largely equalizes brief variations in temperature – so that the machine operates with consistently high precision even with changing ambient temperatures. Its high rigidity and excellent damping provide the basic prerequisites for outstanding surface quality of ground parts and long grinding wheel lifetimes.

The CT550 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. Three inline modular spindles provide flexibility and optimal dimensioning to the machine. The diameter of the HF (high frequency) spindle ranges form 80 mm to 120 mm.

The belt-driven spindle diameter is 80 mm. External grinding wheel is 305 mm. Axes travels are 520 mm (X) and 250 mm (Z). The manual B-axis setting angle is +1 deg / –1 deg. Workhead speed is 1,200 rpm, maximum. Load on the spindle nose, 100 kg. Center height above the table is 1,500 mm. Maximum part length, 650 mm, while the grinding length is 150 mm. Control: the intuitive, easy to use Fanuc 310i-A.

United Grinding universal, external and internal grinders are supported by an expert team of grinding specialists and technicians drawing on more than 10,000 machine installations and a worldwide support and service network.
