Special Features:
Center hole grinding is becoming more and more important for precision components. If several diameters have to be ground on a shaft in different work steps, an exact base is required. With the help of our center hole grinding machines (Fischer system, Dottikon), you can grind this base (centers) with a concentricity of 0.001 mm.Center hole grinding is becoming more and more important for precision components.

Thanks to its wide range of equipment and options, the centre grinding machine can be tailored precisely to your requirements and workpieces.
What is center looping? -> Explanation
From basic manual machines and semi-automatic machines (where individual steps are performed automatically) right through to fully automatic machines, which use a laser to measure the clamped workpiece and grind it automatically with the aid of an ultrasonic sensor – we are sure to find the right centre grinding machine for your needs.

Features of the clamping options
Features of precision chucks
The drive unit (AA) is used to rotate the workpieces. The precision clamping chuck (SP) is mounted onto the drive assembly. The chuck is used for clamping and centering the components. A fixed center (FS) is used as the opposing center.
- Rotating chuck = rotating workpiece
- The parts can be clamped on a rough diameter
with an irregular outer contour - The workpieces can be aligned using the three
individually adjustable quills of the chuck - The workpieces must be inserted into
the chuck from above or below
Features of steady rest
The workpieces are clamped in the steady rest (LM) in such a way that they can still rotate. The drive center (AS) serves both as the opposing center and as the drive for the workpieces. The workpieces, fitted with a drive dog, are mounted on the drive center.
- Fixed steady rest; the workpiece is
driven by the drive center - To achieve good concentricity at the center,
the clamping surfaces of the workpieces must
have good runout accuracy (pre-ground) - The runout accuracy of the center can only be as
good as the runout accuracy of the clamping diameter - Very simple and fast clamping of the workpieces
(no alignment required) - The opening steady rest allows the workpieces
to be loaded from the operator side
