Grinding
An advanced precision machining technology
Let's first look at what was done by our ancestors.... The first grinders appeared 4,000 years ago, allowing our ancestors to refine stone tools. In ancient Greece, the wheels were already cooled with oil or water. In the 15th century, Leonardo da Vinci innovated by designing a needle grinder with an automatic feeding system. It wasn't until 1874 that Brown & Sharpe launched the first cylindrical grinder, allowing for a precision of 0.01 mm.
What is grinding process ?
Grinding is a machining process that involves material removal, aimed at producing high-precision and high-finish parts.
As in all machining, the excess material is removed in the form of chips. The edges of the grinding tools, made up of hard mineral crystals, act as cutting edges.
This process meets modern production requirements, ensuring high quality and a reduced cost per piece. Grinding is ideal for:
- A high precision of measurement and shape
- A defined surface quality
- Machining of difficult material to machining
External cylindrical grinding is used for the production of cylindrical or conical parts, for example for the grinding of shafts, axles, and spindles, which are used in general mechanical engineering, in the automotive industry, or in aviation.
The material is removed with the circumference of the grinding wheel on the circumference of the workpiece. This can be done in a radial (plunging) or axial (longitudinal) direction. Due to the high clamping precision, the workpieces are generally held between centers.
