• Groove Spacing Options: 20×20 / 25×25 / 30×30 / 40×40 mm
• Digital Thickness Adjustment Motor: 0 – 1440 RPM, 0.75 KW
• Feed Speed：1 – 12 m/min
• Application:Deep Grooving Machine is designed specifically for deep groove cutting on balsa wood and structural foam cores (PET, PVC, PU)

Deep Grooving Machine is designed specifically for deep groove cutting on balsa wood and structural foam cores (PET, PVC, PU) – the kind of grooves you need for shear web integration, weight reduction, or resin flow channels in thick composite panels. It runs on a 22KW variable‑frequency main spindle (0–2500 RPM) with a 30KW total power input. The machine handles panels up to 1300 mm wide and 80 mm thick. Groove spacing can be set to 20×20, 25×25, 30×30, or 40×40 mm, and feed speed is adjustable from 1 to 12 m/min. A digital thickness adjustment motor (0.75KW) ensures precise groove depth control, and all parameters are set via a touch screen HMI.

• Deep groove capability – Built for slot depths that go well beyond surface scoring. The 22KW spindle and rigid frame let you cut several millimeters deep without chatter or burning.

• Variable frequency spindle – 0–2500 RPM speed range. Adjust to match material density: slower for dense balsa, faster for soft foam.

• Multiple groove spacing options – Four preset patterns (20×20, 25×25, 30×30, 40×40 mm). Covers most wind blade core designs and structural panel requirements.

• Digital thickness adjustment motor – 0–1440 RPM, 0.75KW. You set the target groove depth on the touch screen, and the motor automatically positions the cutting head. No manual cranks.

• Touch screen HMI – All parameters (depth, spacing, feed speed, spindle RPM) are changed digitally. Save recipes for different products.

• Wide panel width, good thickness capacity – Max workpiece 1300 mm wide × 80 mm thick. Fits standard balsa blocks and foam core slabs.

1. Wind turbine blade core deep slotting
   Shear webs need to sit inside grooves cut into the core material. This machine cuts those slots accurately and consistently across long panels.

2. Structural foam lightweighting
   For PET and PVC foam cores used in marine, rail, or automotive panels – deep grooves remove mass while keeping stiffness. The digital depth control ensures you don’t cut all the way through.

3. Balsa wood end‑grain core preparation
   Deep grooves can accommodate reinforcement inserts or act as resin channels in thick balsa blocks. The machine’s clean cut prevents edge crushing.

4. Composite sandwich panel hinge and fold lines
   When you need to bend a sandwich panel (e.g., for boat hulls or curved truck fairings), deep grooves on the inner side allow the panel to flex without cracking.
