Used Machinery: Grinding machines

Grinding Machines - One Possible Way to Good Surfaces

Typical grinding parts are, for example, hardened components such as shafts, rollers, valves and other sliding surfaces. With the right grinding process and the selection of grinding tools, the desired surface finish can be determined very precisely.

Machine tools with the "grinding" function are referred to as grinding machines. Round parts, flat parts as well as shaped parts can be ground on the grinding machines. One of the more complex processes involved in grinding is, for example, the grinding of gears, internal and external gears.

Now we come to the structure and the most important components of a grinding machine. First of all, the frame or the grinding machine bed should be mentioned here. This carries all important components such as spindles, drives, clamping devices, slides, tools (discs or belts) and the weight of the workpieces. The frame is also responsible for good damping. For certain applications, cast iron frames are very popular because of their good damping properties (avoidance of vibrations that cause chatter marks or shadows on the workpiece).

There are hardly any upper limits to automation with grinding machines. This development goes from the simple bench grinder to the belt grinder, to the surface grinder with magnetic table, through the automated control of the axes and spindles (CNC control) and the increasing number of tools. In the end, the simple grinding machine can be turned into a machining center (grinding center). Grinding machines - optimal structure of the categories on tramao.

At tramao we have decided on the following categorization of the grinding machines:

• Belt grinding machines
• CNC grinding machines
• Continious running grinding machines
• Flat surface grinding machines
• Form grinding machines
• Internal grinder
• Jig grinder
• Crankshaft grinding machines
• Knives grinding machines
• Camshaft grinding machines
• Surface grinding machines
• Profil grinding machines
• Circular grinding machines
• Floor stand grinders, grinder bench
• Grinding centres
• Other grinding machines
• Disk grinding machines
• Cup wheel grinding machines
• Cutting off machines
• Universal grinding machines
• Roll grinding machines
• Tool grinding machines

Special areas also require the development of special grinding machines. This applies, for example, to the gear cutting machine category. That is why the term “grinding machines” appears again in the tramao categorization of “Gear cutting machines”.

The advantages of the CNC grinding machines lie in the economical production of large numbers of pieces with constant quality, as well as a plannable production with constant set-up and production costs. The grinding of generally round workpieces in a continuous process is effective. The workpieces (rollers, shafts, pins) do not have to be clamped and aligned in a time-consuming process, but the grinding wheels are arranged in a form that they automatically center the workpieces.

A grinding machine can also belong to several categories depending on the number of functions within the machine. For example, a surface grinding machine can also be CNC-controlled one. That is why it is possible on tramao.de to assign more than just one category to a machine. However, a maximum of only three categories per grinding machine are possible.

There are many classic areas of application for grinding machines. It starts in small workshops with universal grinding machines and ends with highly complex workpieces in interlinked production systems, where maximum precision is also required from the grinding machine.

There is no typical industry in which grinding machines are used. The automotive industry needs these machines especially in engine construction (internal combustion engines).

However, grinding machines are primarily used in metalworking industries. A large number of other materials can of course also be processed by grinding machines. Examples of this are wood, plastic, glass or composite materials.
