What the center is grinding?
<- Back to the centre of the grinding machine
The center grinding – The ideal and indispensable preparation of a component, in order to obtain the cure, the final high-precision grinding.
By the heat treatment, can bend components. The consequence of non-circular and deformed centering holes, with the result that other grinding operations to inaccurate results. In particular, if the parts are machined after hardening on multiple machines (Circular, Gear cutting, thread grinding, etc.), grinding is the Center of a necessary pre-processing.
Profit:
- High roundness and concentricity of center bore of 0.001 mm
- In deformed components, the axis restore
- The concentricity, for example, between a finished bearing seat and the centring bore in the manufacture
- Minimizing grinding time by a small grinding allowance
- To achieve a higher efficiency, greater precision and a smaller scrap rate for the further processing
- Increase the process safety series
Benefits specially designed with our
precision collet Chuck:
- The centre is coaxial with a bore grinding, although on the deformed and non-circular outer diameter is clamped.
(With the Chuck, the components can be addressed, e.g., in accordance with a hole) - The deliberate displacement of the axis (if the component required)
Application examples
Roundness
To achieve a high roundness and concentricity in the center
Surface texture
The optimum surface for the cylindrical grinding between centers (cross cut)
Out-Of-Round Parts
The alignment of non-circular components with the Chuck, so that the grinding allowance can be minimized
Move the axis
Alignment of the component according to the drilling, and grinding of the center, eccentric to the outer diameter
Position error
Position error of two centers correct
In axis
The axis of two centres, compared with the outer diameter restore
Center angle
Recovery of the desired center angle
The grinding of the centering holes on the center of the grinding machine is very large and unmissable benefits
Through the center of the Form loop and position error is corrected. This hardness deep and grinding offsets are minimized.
Thus, the component has the perfect location for all further processing steps.

Why a ZAMAG center, grinding machine?
All ZAMAG-centre grinding machines work with a rotating workpiece. , This brings many advantages. Components can be clamped to sit with pre-ground or ready-made warehouse is so easy in the bezel. Through these Span the centers are ground automatically coaxial with the bearing seat. However, this requires that the bearing seats have a good roundness, because this is taken over in the ground center.
Even more advantages when Clamping and grinding of the rotating work piece in our precision Chuck. With the help of the three adjustable quill in the Chuck of the parts can be aligned precisely. Thus, it is no Problem to clamp raw or non-circular components. Through the Alignment of the Outer-diameter is ground, the center coaxial with the axis. As a result, the grinding allowance can be kept to a minimum.
It is also possible to clamp the component on the outer diameter, however, to inform according to the bore. Thus, the component is clamped deliberately eccentric. This approach is used, if later, the outer diameter to be ground on the grinding machine, coaxial to a (e.g. honed) bore.
