Peripheral grinding machine – WSL series

WSL: SHAFT AND SERRATED GRINDING

The WSL series grinding station is used as a module in various machines to achieve shaft or serrated grinding.

1. Achieve any cutting edge angle by interpolating the Y and Z axes
2. Heavy welded construction
3. Special 15 kW motor with precision-bearing shaft and mounting flange for 450 mm Ø grinding wheels (usable up to 250 mm Ø)
4. Sanding width max. 100 mm
5. Direct drive of the grinding wheel
6. Programmable, constant peripheral speed with decreasing pulley diameter 30-45 m/s
7. Dressing/profiling of the grinding wheel with diamond-coated profile roller 140 mm Ø, drive 0.75 kW; dressing intervals can be pre-programmed with automatic compensation of wheel wear
8. Dressing with single grain diamond
9. Sanding station each equipped with a vertical slide and a horizontal slide:
   Y-axis = horizontal slide for moving against the workpiece/profile roller
   Z-axis = vertical slide for sanding movement
10. Movement of the CNC axes via AC servo motor with preloaded ball screws

WSL2/3: KNIVES WITH SMOOTH CUTTING EDGE, SCALLOPED GRINDING OR SERRATED EDGE

CNC grinding machine with up to seven axes for processing knives up to 1,800 mm in length and for serrating circular knives up to 250 mm in diameter (optional).

• WSL series grinding station
• Grinding of knives with straight or serrated cutting edges at a programmable angle
• Dressing of grinding wheels for frequently used tooth profiles with dressing device for holding diamond-coated dressing rolls
• Optionally with two-axis CNC dresser for user-friendly programming of tooth shapes via menu
• This enables fast grinding of almost any tooth profile on long knives, even for small quantities or prototypes (especially pointed or serrated teeth)
• Gear cutting on circular knives possible due to additional rotary axis (C-axis)
• Additional B-axis (± 25°) for creating an undercut (WSL3)
