Definition: Cylindrical Grinders

Cylindrical grinders are subdivided into internal and external cylindrical grinders. The combination of both is known as universal cylindrical grinder. They are used for the abrasive machining of cylindrical pieces. A cylindrical grinder consists of, amongst others, a workpiece spindle, a wheel spindle and in most cases a tailstock too. In common external grinding machines, the workpiece is fixed between the centres. However, there are also centreless grinding machines. Internal grinding machines are used when the workpiece has bores or an internal cylindrical surface. In modern CNC universal cylindrical grinders "noncircular" grinding is also possible. At Surplex you will find used cylindrical grinders with different distances between centres, centre heights, grinding lengths and grinding diameters!

Design and method of operation of a cylindrical grinder

Cylindrical grinders are divided into two types: internal cylindrical grinding machines and external cylindrical grinders. The two types can also be combined to form a universal cylindrical grinding machine or CNC universal cylindrical grinding machine. Cylindrical grinders are used to manufacture cylindrical-shaped workpieces in industrial settings. With external grinders, the workpiece is clamped between tips and propelled by a flanged sleeve. The tips are located in the seats of the headstock and tailstock. For pins and fully cylindrical parts, centreless grinding is also possible. This involves laying the workpiece onto a support or guidance rail, which is only a few tenths of a millimetre away from the grinding disc.

The grinding disc presses the workpiece onto the support through its rotary movement and simultaneously rotates the workpiece. If bore holes or other cylindrical interior surfaces are being finished, the internal grinding machine comes into play. These devices possess a swivelling grinding head and cylindrical abrasive bodies. These abrasive elements are smaller than the hole being finished and are powered at high speed.

Development of cylindrical grinding machines

Cylindrical grinding machines were developed to perform the tasks which turning machines were incapable of performing.

These primarily involve the processing of hardened materials in accuracy ranges of 1/1000 mm. Older machines were operated manually and only external grinders were automated for feeding and laterally moving the table. Nowadays, modern cylindrical grinders feature CNC controls, which enables highly precise, cost-effective work and are thus also termed ‘CNC cylindrical grinding machines’.

Fields of applications for cylindrical grinding machines

Cylindrical grinding machines are used to finish workpieces whose surfaces must be precise and evenly sanded. Even hardened materials can be finished with ease using these machines. Cylindrical grinding can also be used whenever a lathe is reaching its limits. These machines are used for producing individual items and industrial-scale serial manufacture. Cylindrical grinders are used wherever there is construction of machinery, plants and tools. One possible application is the machining of circular punches for cutting tools. These circular punches are made from hardened tool steel and must feature an exact length and precise circular dimensions, which is difficult to achieve cost-effectively using a lathe. Used cylindrical grinding machine prices are often greatly lower than that of new devices.
