Universal Cylindrical Grinding Machine GD-8020B

Key Features of the GD-8020B Cylindrical Grinding Machine

Purpose and Application
The machine is designed for high-precision external and internal grinding of cylindrical, conical, and end surfaces of parts made from hardened and non-hardened steels, cast iron, and non-ferrous alloys. It is used in toolrooms, repair workshops, and for manufacturing and restoring shafts, axles, bushings, rings, and other precision components.

Design Features

• Rigid cast-iron bed ensuring geometric stability under load and minimal vibration.

• High-speed grinding spindle mounted on precision bearings, providing stable wheel operation without runout.

• Capability to install an internal grinding attachment for machining bores with diameters starting from 8 mm.

• Longitudinal table travel with mechanical feed and automatic reversal at stroke endpoints.

Cooling System and Safety

• Integrated coolant supply system with adjustable flow rate and direction for efficient heat and swarf removal from the cutting zone.

• Transparent safety guard with mechanical interlock that prevents machine startup when the guard is open.

Operational Advantages

• Simple and intuitive control system with separate handles for manual and mechanical feed.

• Quick reconfiguration between external and internal grinding operations without special tools.

• Low noise and vibration levels due to balanced construction and high-quality dynamic spindle balancing.

Reliability
The machine is engineered for continuous 24/7 operation in industrial production environments. All structural components are made of high-grade cast iron and undergo stress-relief aging treatment. The table guideways are hardened and ground, ensuring long service life and maintained accuracy throughout the machine's operational lifetime.
