Leading Technological Developments
Precision, performance, reliability - these are the strengths that make WaldrichSiegen sanding and texturing machines stand out on the market. Continuous further development, always geared to the changing requirements and challenges of the market, has made us the technology leader.
Roll Grinding Technology
X-Axis With V-Shaped Guideways for Precise Guidance of Moving Components
- • Precision and high stability and accuracy in movement
- Self-centering for greater running accuracy and adjustment of moving parts
- Low wear and increased component service life
Grinding Carriage B Axis
- • The B axis integrated into the grinding carriage guarantees tremendous precision at maximum cutting forces and stock removal rates along the roll geometry.
- Eccentric grinding axis bearing for optimum machining of complex geometries
- • Guarantees consistently high surface quality of various cam shapes from infeed increments as small as 0.0001.
- • Highest accuracy of the infeed increments of 0.0001
Fine Infeed of the U Axis
The stable and low vibration “monoblock” wheel head design with eccentric hollow shaft ensures a high degree of positioning accuracy. The design ensures that the grinding wheel is aligned to the roll with high precision, especially in the X axis (i.e., the horizontal axis), which makes precise machining and uniform wear of the grinding wheel possible.
Two-Point Measuring System
The two-point measuring system from WaldrichSiegen provides the geometric measurement data of the rolls. It measures the roll with great precision with 360 measured values from stock removal and diameter to shape, roundness, and eccentricity per revolution. The measurements are taken both before and during the grinding process.
