Cylindrical grinders for internal and external work

Cylindrical grinders are available in two forms: internal and external cylindrical grinders. Both processes can be combined into a universal grinder. These machines are used for the industrial production of cylindrical workpieces. The external grinders clamp in the workpiece between two points and move it with help of a driving ring.

  • Creates cylindrically formed workpieces

Therefore, there is a receptacle point on the headstock and the tailstock. For spikes and fully cylindrical pieces, these can also be ground centreless. The workpiece is thereby on a support or guide rail that is only a tenth of a millimetre away from the grinding disc. Using a rotating movement, the grinding disc presses the workpiece onto the support, while simultaneously turning it. Internal cylindrical grinders are used for any other boreholes or cylindrical internal surfaces that need to be ground. These use a swivelling grinding head with a corresponding cylindrical grinding body. The grinding body is smaller than the borehole and moves at very high speeds.

Background and the development of cylindrical grinders

Cylindrical grinders were developed in order to undertake processes that were not possible with a lathe. This primarily refers to the processing of hard materials with an area of accuracy of 1/1000mm. The older machines were manually operated and the only sections that were automatic were the feed and the traverse motion of the table (with external cylindrical grinders). Modern cylindrical grinders have CNC-control that enable highly precise and economic work.

Areas of application and examples of cylindrical grinders

The cylindrical grinder is used for the finishing of workpieces that require very accurate and clean surfaces. Especially hard materials can be processed using this machine. Cylindrical grinders are also used for tasks which lathes cannot undertake. These machines can be used for individual products or for industrial mass production. Cylindrical grinders are found in all plants that build machines or tools.

A possible use is also the processing of round punches for cutting tools. These round punches out of hardened steel have to be very precise and equally rounded along their whole length, which is not something that is economically achievable using lathes.

Brand names and manufacturers of cylindrical grinders

Several companies have specialised in the manufacturing of cylindrical grinders. Some of the most recommended suppliers include ABA, DANOBAT, KARSTENS, MSO, STUDER, SCHAUDT, WMW, and TOS.
