High-precision grinding as a finishing operation in precision production
At Tumag, precision grinding is an essential part of the high-precision production of moulds, cutting tools and precision mechanical components.
Precision grinding, also known as industrial grinding, is the micron-level finishing of metal components using a rotating grinding wheel to achieve tight dimensional, form and surface tolerances. While milling, turning or EDM machining create the basic shape, our grinding techniques ensure the final dimensional stability, surface quality and fit that make the difference in demanding applications.
Think of precise closing surfaces in moulds, wear-resistant cutting edges in stamping tools and high-quality finished precision parts for precision engineering applications.
Thanks to a modern machine park, experienced specialists and strict quality control, we can combine complex geometries, hard materials and exceptionally high accuracy within one controlled process.
Our precision grinding techniques under one roof
Precision grinding is an accurate finishing operation within high-precision production and is a core competence at Tumag. Grinding is the ideal technique for applications where accuracy, form tolerances and very low surface roughness are crucial. To meet the strictest tolerances and a wide range of geometries, we offer a broad range of specialised grinding techniques in-house.
With our advanced surface grinding machines, we guarantee superior flatness and a perfectly parallel finish for your components. This technique is ideal for machining stamping parts, mould plates and guide elements where consistent thickness and minimal tolerances across the entire surface are required. Even for larger workpieces, we ensure uncompromising accuracy.
For both internal and external cylindrical grinding, Tumag is the right partner. We produce perfectly cylindrical components, shafts and bushes with extremely tight fit tolerances and flawless concentricity. Thanks to our advanced clamping techniques and finely tuned process control, we minimise form deviations and deliver an impeccable surface finish on your round components.
When your parts require complex geometries, specific grooves or intricate contours, we use profile grinding. Thanks to the extremely precise dressing of our grinding wheels, we can transfer complex profile shapes flawlessly onto hardened materials. This makes profile grinding indispensable for the production of high-quality cutting and forming tools.
For bores and contours that require extreme geometric and positional tolerances in relation to each other, coordinate grinding is the ultimate solution. This technique enables us to finish hole patterns and complex internal shapes in hardened workpieces with high precision. Where traditional techniques reach their limits, coordinate grinding guarantees exact positioning.
The added value of Tumag in precision grinding work
Tumag’s added value lies not only in the grinding itself, but in the way we integrate this operation into the complete production process. Grinding is never a standalone process for us. It is part of a broader precision approach in which engineering, machining, EDM, metrology and assembly are aligned.
For customers, this means: less risk of deviations, a more stable production process and components that perform exactly as intended, even in critical applications.
This delivers tangible benefits:
- Process knowledge across the entire chain
We understand how a part has been pre-machined and which tolerances, stresses and functional areas are critical in the grinding phase. - Better dimensional accuracy and repeatability
By combining grinding with in-house quality control and measurement reporting, we maintain maximum control over the final result. - More efficient lead times
Because multiple precision operations take place under one roof, we can move faster and avoid unnecessary handovers between external parties. - Craftsmanship combined with technology
High-end grinding requires not only machines, but also experience in clamping, material behaviour, shape correction and finishing. That is exactly where Tumag makes the difference.
Frequently asked questions about our grinding services (FAQ)
Why is grinding important in high-precision manufacturing?
Grinding is often the final and most decisive operation for finishing a part to the exact dimensions and surface quality required. Especially for moulds, stamping tools and precision mechanics, this is essential for the part’s performance and service life.
What determines the quality of high-end precision grinding work?
Tumag combines grinding technology with broad expertise in engineering, machining, EDM, quality control and precision assembly. This allows us to align grinding perfectly with the full production context of the part.
For which parts is precision grinding used?
We grind mould components, stamping tool parts, guide elements, fitting surfaces, profile shapes, shafts and other precision mechanical parts. This technique is used wherever accuracy, dimensional stability and finishing are critical.
