In industrial production, deviations of even a few hundredths of a millimetre can lead to malfunctions. This is why technical shaft grinding is not a cosmetic treatment, but a critical step in the manufacture and refurbishment of shafts.
At Dessa-NV, this process has been perfected.
🔧 What is technical shaft grinding?
Grinding is the precision machining of a shaft surface that allows you to achieve:
- perfect geometry and alignment,
- a given surface profile (straight, bombardment, saddle, cone),
- of a given degree of roughness - from Ra 0.3 to 2.5 microns,
- no breakage,
- profile grooves, spirals, diamonds, etc.
We use high-precision CNC equipment that allows us to process shafts up to 7 metres long and 900 mm in diameter, weighing up to 10 tonnes.
📐 Shaft profiling: more than just grinding
In contrast to conventional grinding, profiling is the creation of a special shape for the working surface of a shaft. Depending on the function of the shaft, we shape:
Profile | Where it is used |
Direct | standard surface without material deformation |
Bombsuration | pulp and paper production, weaving equipment, packaging and film production |
Saddle | Compensation of thermal stresses or edges |
Cone/step | Feeding or removing material |
Grooves, diamonds, cross notches | for adhesion, glue, lubrication, etc. |
🧪 Quality control after grinding
Each shaft is checked for the following after machining:
- radial and axial runout,
- imbalance,
- conformity of the geometry and profile to the drawing,
- surface roughness,
- no defects or microcracks.
We use indicator watches, calibres and digital Ra meters.
🏭 Which shafts are used for grinding
- Rolls for offset, flexo and gravure printing
- Pressure rollers in the film, paper and textile industry
- Rollers for applying varnish, glue, grease
- Transport and guide shafts
- Grooved shafts for roller systems
- Shafts coated with NBR, EPDM, PU, silicone
