Deburring

Finish

WEBER NLC sanding technologies 

For surface finishing and deburring, we use rubber-coated grinding rollers. The grinding pressure is generated by lowering the roller compared to the set workpiece thickness. Their use ensures uniform removal of burrs, resulting in a smooth surface. The contact roller is particularly effective for rough grinding, as it effortlessly removes thick, melted laser splatter. The contact roller is precisely controlled and usually positioned slightly below the zero line, allowing for flexible adjustment of the grinding pressure and meeting the requirements of various workpieces. To ensure quick and precise positioning, the unit is equipped with electric adjustment and can be accurately positioned and readjusted during operation. The contact roller unit is equally prepared for the use of Scotch-Brite belts. Grinding rollers are available in various diameters and rubber hardnesses and can be adapted to all parts to be ground.

Technical Specifications:
+ Rubber-coated 40-90 Shore
+ Drive depending on the series up to 110kW
+ Electric roller adjustment and positioning

Features:
+ Use of different belts possible
+ Removes thick, molten laser spatters
+ Effective for rough grinding
+ Surface grinding
 

For uniform all-around edge rounding on all inner and outer edges, multiple rotating heads are arranged side by side. The intermeshing of the brushes, with two brushes per head, ensures consistent processing results across the entire width. Due to the compact design, the brush head can be easily combined with other WEBER grinding technologies. The multirotation brush is ideal for processing coated materials, such as foil-coated sheets or galvanized sheets, where the coating must not be worn off or damaged.

Technical Specifications:
+ Drive 2,6kW per unit 
+ Speed frequency-controlled 30-150U/min 
+ Cutting speed frequency-controlled 5-20m/sec 
+ Electrical height adjustment and positioning

Features:
+ Grinding-brushing station with multiple horizontal rotating units 
+ Each with 2 vertical rotating brushes 
+ Flap brushes are quick-changeable 
+ Side extension for easy tool change

 

 

As an alternative to the compact design of the “P2“, WEBER also offers a double-row arrangement, where each tool carrier holds six brushes. This unit is equipped with an electric adjustment system, allowing for quick and precise positioning. It can be activated, deactivated, and precisely positioned and readjusted during operation via a program.

Technical Specifications
+ Drive per unit up to 2,2kW 
+ Disc station with electric height adjustment and positioning

Features
+ Number of units adjusted to the working width, each with 6 tools 
+ Tools with quick-change system + Side extension for easy tool change

The WEBER brush unit enables the use of special abrasives that aren’t available as abrasive belts. The brushes treat the surface and, in part, the edges. The oscillating brush system is adjustable and is used primarily for longitudinal sanding. The brush rollers improve surface quality, alter surface roughness depth, or modify the surface structure.

Technical Data:
+Drive power up to 37 kW
+ Cutting speed 5–18 m/s
+ Display accuracy 0.1

Features:
+ Adjustable oscillation

Wet sanding technology

Many years of experience and sophisticated technology make WEBER wet grinding the first choice. The proven technology ensures first-class results. WEBER always pays particular attention to the economic efficiency and environmental friendliness of the systems. The cleaning systems required for the grinding liquid are extremely economical and are characterized by simple operation, cleaning and maintenance.

 

 

For difficult parts

The sophisticated WEBER wet sanding technology is convincing when sanding special materials, where there is a risk of excessive material heating, as well as with very oily sheets. Special surface quality requirements can also be met with wet grinding. WEBER wet sanding uses specially developed sanding techniques. The planetary head system, brush systems and sanding rollers ensure perfect surface quality during wet sanding.
