The full cover type is equipped with a safety door lock system.
During grinding operations, the door remains locked to prevent unintended access by the operator and to securely protect the machining area. This reduces the risk of accidents during processing and allows grinding operations to be safely controlled in manufacturing environments where compliance with safety regulations is critical.

During grinding wheel replacement or inspection, conventional machines often require the cover to be lifted manually or with the assistance of a crane. The SGC 300 Full Cover Type addresses this inconvenience by adopting a cylinder assisted automatic opening system, allowing the cover to be opened smoothly with the push of a button.

Because no manual lifting or crane is required, maintenance tasks become significantly easier, operator workload is reduced, and downtime of the grinding machine is minimized, contributing to tangible improvements in overall operational efficiency.

The bed of the SGC 300 can be configured with two options: iron casting and mineral casting. While both structures provide stable grinding performance, the Full Cover Type is designed with a mineral casting bed that offers superior vibration damping and thermal stability, enabling higher overall precision.

The mineral casting bed applied to the Full Cover Type is supplied by SCHNEEBERGE of Switzerland, whose products are widely used in the European machine tool industry. The inherent vibration absorption characteristics of the mineral bed effectively reduce micro vibrations generated during grinding, improving surface quality and tolerance retention while ensuring stable results in precision machining.

In addition, compared to conventional iron casting structures, the mineral casting bed allows for a reduction in overall machine weight, contributing to improved energy efficiency. Its low sensitivity to temperature fluctuations also minimizes thermal deformation, reducing machining errors during long operating periods. These characteristics further enhance stability and repeatability in grinding processes where consistent precision is critical.

Machinable Parts for Centerless Grinding _ AI-Generated Image β“’ ChatGPT

Centerless grinding is an essential process for high speed and high precision machining of cylindrical components such as pins, valves, shafts, camshafts, and ceramic parts. In applications where a surface roughness of Ra 1 to 5 and high repeatability are required, the centerless grinding method, which enables continuous machining without center fixation, offers an optimal balance between productivity and quality.

Thanks to these advantages, centerless grinding machines are widely used across various industries, including shaft and drivetrain components in the automotive and electric vehicle EV sectors, engine, structural, and defense components in the aerospace and defense industries, as well as bearing and precision machinery parts. ORSKOREA’s centerless grinding solutions are designed with a wide range of materials and machining conditions in mind, delivering stable grinding performance in industrial environments that demand both high speed production and superior surface quality.
