Software • StuderWIN or StuderSIM simulation software for the creation and simulation of grinding programs on the machine control or on a PC • Small space requirement • Optimal accessibility • Low unit costs • High flexibility • Simple operation • Low maintenance costs Unique worldwide The other very compact machine concept. The workpiece is moved on the cross-slide, while the grinding spindles are mounted in a fixed position on the base of the machine. This guarantees stability, offers good accessibility for set-up or workpiece change, and is easily automatable. The spindle set-up,...

The machine bed, comprising of gray cast iron, is cast from a single piece and forms the base for mounting the high-precision cross slide table and the grinding spindle mounting block. The support of the guides for the X axis is cast directly into the machine base. The remaining area on the upper part of the machine base conveys the coolant around the base back into the coolant unit or the coolant cleaning unit, via a coolant tank. • High geometrical traverse precision • Effective covering of the guideways The generously dimensioned cross slide is manufactured from quality cast iron. Ground...

Grinding spindle support / Grinding spindle arrangement 1 The modular grinding spindle support concept enables optimal adaptation to the respective grinding task. The grinding spindle supports comprise of permantly boltedon solid mounting blocks, either in a single or twin version, depending on the requirements. One, two or three spindles in a linear arrangement can be used in the basic configuration. The use of up to three spindles is possible depending on the specific geometrical situation. In the case of two or three grinding spindles the maximum possible grinding length is restricted....

The high-precision workhead is equipped with special bearings and guarantees the highest roundness accuracy. The spindle nose complies to the DIN / ISO 702 - 1 standard. A high-precision C axis, with direct measuring system on the workhead spindle, is available for form and thread grinding. • High roundness accuracy • Low-maintenance • Air lift Cones and tapers can be machined in two ways. Either by using a swivelling work table with a manually adjustable range of up to 21 deg (31 deg for S110) or with a fixed table and an appropriately dressed conical grinding wheel. © S110 work table,...

• Air-gap elimination • Set-up assistance • Process reliability • Process optimization STUDER attaches great importance to optimized grinding processes. Sensor technology plays a significant role here, especially in internal grinding. Three main goals are pursued: • Air-gap elimination for cycle time reduction • Process monitoring during grinding and dressing • Simple registration of grinding wheel and workpiece With small bore diameters it is particularly difficult to obtain a contact signal. STUDER achieves the best result with a ring sensor consisting of a revolving transmitter ring and...

The wide variety of dressing options enables optimal adaptation of the machine to the most diverse applications and workpiece requirements. In addition to fixed dressing units, devices for rotating dressing tools can also be mounted.
