Automatic grinding unit

The quality requirements on cutting results are high and rising further, especially in the automotive sector. Accurate cutting within narrow margins of tolerance is essential in order to obtain a quality product. A good cutting result requires a flawless cut surface without any rippling or mismarkings – even with difficult materials.

Automatic grinding without manual handling

Increased lifespan of band knives and cup wheel grinding stone

Consistently good cutting results

Higher productivity thanks to avoided downtimes

Automatic grinding – a piece of cake

The blade is automatically sharpened, its heels are kept even.

The usage of blades is plannable and fewer blades are needed in total as the preset modes are optimized for the relevant application

Automated dressing of the cup wheel grinding disks - only as far and as often as necessary, prolonging the lifespan

Reinforced cup wheel grinding disks with an increased diameter of 150 mm and a wall thickness of 15 mm increase the grinding performance as the blades are sharpened more quickly and are maintained in sharp condition. The feed motion and the adjustment of the grinding disks is performed automatically by a servo drive.

The manual grinding procedure is time-consuming. With the automatic grinding unit, the cutting simply continues during grinding – no downtime necessary.

Incorrectly ground band knives increase the scrap rate

The prerequisite for optimal cutting results is a perfectly ground cutting tool. But not every operator is sufficiently experienced to be able to choose the grinding settings required to get an optimal result.

Incorrect grinding can damage the band knife, negatively affect the cutting result and cause production losses.

Therefore, our “automatic grinding unit” includes an intelligent control unit that monitors itself and performs optimal grinding cycles for the Bäumer band knife.


Integrated software enables individual settings

Our control offers you a choice of three preset grinding modes. These can easily be selected and modified via the control touch panel.

1. Strong grinding:

After a change of blade or when cutting rubber or cork rubber rebond foams.

2. Normal grinding:

When cutting harder materials such as PU rebond foams with high volume weights and PE materials.

3. Polishing:

When cutting PU foams with light cutting pressure and high quality requirements for the cut surface (e.g. for the automotive industry).

The cleaning of the cup wheel grinding disks is fully automated with two pneumatically operated cylinders and truing diamonds. This way, we ensure a constant chamfer and consistent sharpness of the band knife.

In addition, there are the special functions “cup wheel grinding disk change” and “diamond screw change”. For these, each motor moves to a fixed and preset exchange position so that the machine operator can exchange the wear parts quickly and easily.

Obtaining the highest accuracy for your cut product matters to us.

Simple operation

The operation is very simple. The different modes can be accessed via a small panel directly on the grinding unit.
