CNC Grinding Machines

The name ‘Micromatic’ is synonymous with ‘Precision Grinding’ in India since 1973. Micromatic Grinding Technologies is India’s largest CNC Grinding Machines manufacturer, catering to domestic and export markets worldwide. MGT has been manufacturing a wide range of External, Internal, Universal and Special Purpose cylindrical grinders in CNC, PLC and Hydraulic versions.

Vertical Double Disc Grinder - VDG 600

At IMTEX 25, MGT introduces the VDG 600, a Vertical Double Disc Grinding Machine, which has been developed to fulfil the market demand for grinding two surfaces simultaneously with automatic wheel positioning and dressing compensation with a CNC system.  

The MGT Vertical Double Disc Grinding Machine is a high-performance, compact, and high-speed CNC-controlled precision grinder. It is designed for simultaneously grinding two parallel surfaces of flat metallic parts such as valve plates, piston rings, bearing races, oil pump vanes, impellers, and seals.

The machine features a rigid, fabricated machine bed structure that has been stress-relieved to provide high static and dynamic rigidity. This design facilitates the easy flow of coolant and grinding dust. Equipped with high-precision, anti-friction wheel head spindles running in a combination of double-direction angular thrust bearings and double cylindrical roller bearings, it ensures high stability and rigidity of the grinding head.

The VDG 600 Precision Double Disc Grinding Machine includes a hydraulically operated swing-arm type wheel dresser with infinitely variable speed and hydraulic lock. It can accommodate a maximum grinding wheel size of f600 mm and 50 mm in width. The two grinding wheel spindles are powered by 22 kW motors, providing robust performance.

Additionally, the wheel surface speed is 33 m/s, ensuring efficient material removal and high-speed grinding. Versatility is another key feature of the VDG 600, as it is adaptable to a wide range of applications across various industries with a customized carrier plate. The VDG 600 design supports a flexible automation concept for a high production rate and includes provisions for a post-process gauge to ensure job conformity. The machine features full guarding and an ergonomically designed, flexible operator pendant that can be operated from multiple positions.

Salient Features

Rigid and Precision Spindle: The machine features high-precision, antifriction wheel head spindles constructed from a single-piece forged spindle. This design incorporates a combination of double-direction angular thrust bearings and double cylindrical roller bearings, ensuring high precision and rigidity of the grinding head.

Robust Construction: The machine features a rigid, fabricated bed structure that has been stress-relieved to provide high static and dynamic rigidity. This design facilitates the easy flow of coolant and grinding dust, with a coolant pan positioned over the bed to prevent any contact between the coolant and the bed's geometry, ensuring high thermal stability.

Precision Infeed Axis: The spindle infeed system features a heavy-duty screw and nut arrangement with a quill sleeve feed design, providing enhanced rigidity and precision. This configuration ensures a high degree of responsiveness of up to 0.001 mm.

Versatility in Applications: The machine's flexibility extends to a range of applications, making it adaptable to diverse grinding needs across various industries with a customized carrier plate.
