High Roundness / exact to 0,001 mm / designed & made in Germany / Highest roundness for your workpiece

Centre Grinding Machine ZS ONE for a high roundness of small workpieces


The Henninger centre grinding machine ZS ONE for a high roundness of small workpieces is designed and manufactured in Southern Germany.

When developing the ZS ONE, we put great emphasis on an especially compact, high-precision and simplified design. Moreover it was important to us that the centre grinder could offer intuitive and fast handling. This means it can be used flexibly as a table machine and is also easy to transport.

Unlike other Henninger centre grinding machines, its maximum load weight is 5 kg. It is operated manually, but an option for automation exists as a custom solution. We can offer further options upon arrangement.

Henninger Centre Grinding Machine ZS ONE for high roundness of small workpieces

What is the benefit of centre grinding?


What can the ZS ONE offer besides high roundness?


As with any other Henninger centre grinder, centre grinding with the ZS ONE bringshigh precision to the entire manufacturing process. The centring hole is being perfected so that roundness of up to 1 µm can be achieved. Hence the ZS ONE centre grinding machine for a high roundness of small workpieces offers just as much precision as its bigger siblings.

Grind the outer contours of your workpieces after centre grinding as precisely as never before!

The ZS ONE impresses not only with its high quality and precision, but also with its very simple way of operation. When developing the ZS ONE, it was important to us that workpieces could be machined quickly and easily.

How does the centre grinder ZS ONE work?


The ZS ONE is used to rework centring holes after the hardening process. The workpiece is clamped in a precision bearing-mounted chuck. The rotary grinding process begins.

The centre is thus being put in line with the axis of rotation. After machining, the roundness in the centre corresponds to the roundness of the rotary axis, i.e. the runout of the chuck bearing: approx. 1 µm.

The tool is outside the axis of rotation. The feed movement is at a 60° angle to the axis of rotation. This causes the mounted point to move into the workpiece exactly normal to the lateral surface of the centre.

The spindle can be moved axially to adjust the projection length.
