Cylindrical and surface grinding

with the greatest precision

Anyone hoping to achieve superior surface quality and low roughness/high smoothness simply cannot ignore the benefits of grinding — especially for hard materials. Even though innovative machining techniques such as high-speed cutting are gradually approaching the same tolerances, grinding remains unrivalled as a hard machining finish (HRC 60-70). With the great variety and number of grinding machines we have here at De Beleyr — offering precision down to Ra 0.01 µm — you've come to the right place for all your grinding, polishing and superfinishing needs!

Cylindrical grinding up to 11 metres

Using conventional cylindrical grinding machines for single items or large parts and CNC cylindrical grinders for greater volumes, De Beleyr is able to meet the highest standards in terms of surface quality, without any compromise. With a cylindrical grinding machine that boasts an impressive capacity of up to 11 metres, size poses no problems when it comes to cylindrical production of components, while convex, concave and crowned grinding are also possible.

Surface grinding

Aside from cylindrical grinding, our workshop can also handle conventional surface grinding projects for parts without complex programming, single items or large parts. Our surface grinders achieve a level of precision down to 2µ, at an angle if required through the use of sine tables.
