Construction and technology

Rigid frame and precision components

The Cylindrical and Internal Grinding Machine Ø200x500 mm features a robust 3000 kg design ensuring stability during machining. Equipped with precision guideways and a spindle driven by a 4 kW motor, it operates with a grinding wheel sized Ø400x50xØ203 mm for efficient external grinding. The internal grinding head, powered by a 1.1 kW motor, allows precise finishing of internal surfaces.

Advanced feed system

The machine provides a maximum cross-feed of 205 mm and precise coarse (2 mm/rev) and fine (0.5 mm/rev) adjustments. A minimum feed of 0.0025 mm and wheel wear compensation of 0.0025 mm guarantee exceptional accuracy. The hydraulic table drive ensures smooth movement, essential for precise operations.

Cooling system and workholding

The cylindrical grinder is equipped with an efficient cooling system powered by a 0.125 kW pump with a flow rate of 25 L/min, protecting both the workpiece and the grinding wheel from overheating. The 165 mm 3-jaw chuck and rotating headstock with MK4 taper provide secure clamping, increasing safety and precision.

Precision and performance

The Cylindrical and Internal Grinding Machine Ø200x500 mm delivers excellent surface finish thanks to its precise feed control and rigid structure. The maximum external grinding length is 500 mm and internal 100 mm, enabling the machining of components of varying dimensions. The wheel’s surface speed of 35 m/s and table swivel range (3° right, 9° left) allow adjustment to specific requirements, ensuring smooth surfaces with minimal tolerances.
