The most compact
design!
Ideal for tool and die construction, mechanical production,
design processes, laboratories and training
The
functionality of the Multi-Grind ranges from external and
internal cylindrical grinding to taper grinding. The Multi-
Grind also allows easy tool grinding
(sharpening of cutters, reamers and turning tools) and is
suitable for light surface grinding jobs.
Three-Point Bearing
The custom three-point bearing of the grinding
spindle ensures minimum temperature effects and consistent
grinding quality.
Feed Drives
Hydraulic table feed (longitudinal) with
automatic change of direction. An additional manually operated
longitudinal feed with hydraulic support allows
feed speeds up to 7 m/min.
Grinding Headstock
Special grinding headstock design allows
simultaneous setup of 2 different grinding wheels. The grinding
headstock travels transverse, is height adjustable,
and swivels around the vertical axis.
Speeds
The headstock operates at 3 different speeds
(110, 200, 300 min-1) which are set through an easy
to operate gear shift lever.

The
grinder is a tooling grinding machine designed to perform rotating
tooling including cylindrical and tapered tool, and also cutting end
face and radial surface could be sharpened at the same time. As the
reason of the part held with air bearing, and so the grinder is very
convenient in operation, high-precision in revolution, simple in
construction, fairness in layout, high-rigid in system, multiple
accessories with the grinder and high efficient in production. The
grinder is one kind of multipurpose rotating tooling sharpening
equipment.
