The offered cylindrical grinding machines are characterised by stable operation and low noise emission. Thanks to the use of screw pumps in the hydraulic system, they ensure smooth and quiet performance. In addition, the spindle of the grinding head provides high rotational precision and excellent rigidity.
The Cylindrical and Internal Grinding Machine Ø320x2000 mm is an advanced industrial machine designed for precise grinding of external and internal cylindrical surfaces. Its robust construction, high power and modern technologies guarantee reliability and efficiency in demanding production environments.
The Cylindrical and Internal Grinding Machine Ø320x2000 mm is a complete solution for industrial plants requiring precise machining of cylindrical parts with diameters up to 320 mm and lengths up to 2000 mm. Equipped with an advanced hydraulic system with screw pumps and a high-rigidity grinding head spindle, the machine ensures stable operation with minimal noise levels. A powerful 9 kW motor drives a 500x50x203 mm grinding wheel, enabling efficient machining of external diameters (8–320 mm) and internal bores (30–150 mm). The hydraulic table feed system with a speed range of 0.1–4 m/min and a swivelling worktable (-3°/+6°) ensure flexibility and precision across various applications. Rich standard equipment, including an internal grinding head and a 3-jaw chuck, and optional accessories such as a closed steady rest or a diamond dresser, make this machine adaptable to specific production needs.
The Cylindrical and Internal Grinding Machine Ø320x2000 mm features a massive structure weighing 4500 kg and measuring 5800x1810x1515 mm, providing stability when machining parts weighing up to 150 kg. The precision-engineered grinding head spindle and sturdy guideways minimise vibrations, ensuring a superior surface finish. The 500x50x203 mm grinding wheel with a peripheral speed of 35 m/s guarantees efficient external cylindrical grinding.
The machine offers a maximum table travel of 1600 mm, supported by a hydraulic feed system with a speed range of 0.1–4 m/min. The worktable can be precisely adjusted within -3°/+6°, providing flexibility for complex grinding operations.
The cylindrical grinder is equipped with an efficient cooling system with an integrated coolant tank, preventing overheating of both the workpiece and the grinding wheel. The 3-jaw chuck and optional 4-jaw chuck ensure secure workholding, enhancing safety and machining accuracy. The internal grinding head allows machining of bores up to 125 mm deep.
The Cylindrical and Internal Grinding Machine Ø320x2000 mm ensures excellent surface finish through precise control and a rigid design. The maximum external grinding length is 2000 mm, while the internal grinding depth reaches 125 mm. The grinding wheel speed (35 m/s) and spindle speed range (25–220 rpm) allow optimal parameter adjustment for different materials, achieving mirror-smooth finishes with minimal tolerances.
