The 2M912A Universal Tool Grinding Machine is one of a kind and achieves grinding with utmost precision across a range of cutting tools. Built for modern workshop precision grinding requirements, this machine is especially useful for sharpening and tool making as it achieves versatility and accuracy with drills, milling cutters, reamers and other cutters with complex shapes.
With considerable functions, the Multi-Grind can do external, internal, taper, tool, and light surface grinding.
Consistent grinding quality is achieved by a special designed three-point bearing which minimizes temperature change.
With hydraulic and manual longitudinal feeds, longitudinal feeds can be achieved up to 7 m/min with automatic direction change.
The grinding headstock allows the use of two wheels and possesses transverse and vertical movement, rotation, and three adjustable speeds.
These include the central lubrication system, the robust construction to minimize vibration, and the easily accessible electrical components, which are stored in a control cabinet.
