Product Description
The 3‑Axis CNC Balsa Cutting Machine is a straightforward, reliable CNC router built specifically for cutting and grooving balsa wood. Unlike its 5‑axis counterpart, this machine moves only in X, Y, and Z directions – perfect for flat sheets, straight or contoured cuts, and repetitive grooving tasks. It comes with three spindle motors, a touchscreen control panel, and a heavy‑duty frame. If your work doesn’t require tilting the tool or cutting undercuts, this machine gives you all the precision you need at a lower cost.

Features of Double Side Shallow Grooving Machine
Simple 3‑axis linear motion – Moves left/right, forward/back, and up/down. Ideal for 2D and 2.5D cutting tasks like profiling, pocketing, and straight‑line grooving.
Cost‑effective design – Uses three 3.7 kW spindles instead of five larger ones, saving both initial investment and energy consumption (15 kW total vs. 40 kW on 5‑axis).
Same large work envelope – Handles balsa sheets up to 1200 mm wide and 76 mm thick, just like the bigger model. Great for batch processing multiple small parts.
Adjustable groove spacing – Switch between 1‑inch and 2‑inch pitch instantly. Works perfectly for wing rib slots or structural core grooves.
Digital thickness control – A dedicated 1.5 kW motor lets you dial in cutting depth from the touchscreen – no manual fiddling.

Application Areas
Model aircraft wing rib production – Cuts dozens of identical balsa ribs with precise grooves for spar insertion. Fast, repeatable, and waste‑free.
Straight‑line grooving for core materials – Creates parallel grooves in balsa panels so they can be bent around curves (e.g., for wind turbine blade shells or boat decking).
Hobbyist & school workshops – A perfect entry‑level CNC for RC plane builders, STEM labs, and maker spaces. Runs on standard 380V power and doesn’t need complex fixturing.
Batch balsa sectioning – Sections large balsa boards into smaller blanks for further processing (e.g., blocks for carving or sanding).
Packaging inserts – Cuts custom foam or softwood shapes for protective packaging – clean edges with no dust.
