Panel Dividing & CuttingModel: TD-420

TD-420 CNC Panel Saw | 4200 mm Beam Saw

Name: TD-420 CNC Panel Saw | 4200 mm Beam Saw
Brand: Tuodiao CNC

TD-420 CNC beam saw with a 4200 mm working length and 120 mm cutting thickness for jumbo sheet breakdown. 15 kW main saw with independent 2.2 kW scribing saw, servo-driven carriage and feeding, air-cushioned ball table, ±0.1 mm cutting accuracy, and an interface to order-splitting and nesting software.

Key Features

4200 mm working length and 120 mm stack height: jumbo and oversized sheets cut in one pass, and taller stacks raise output per cycle

15 kW main saw with a separately driven 2.2 kW scribing saw scores the underside before the main blade, so double-faced laminated panels stay chip-free

Servo-driven saw carriage with 0–120 m/min return speed keeps non-cutting travel short on high-mix cutting lists

Clamping beam and main saw raise and lower automatically with the cutting thickness, so switching board stock needs no manual re-setting

Manipulator feeding on a high-precision reducer with ground rack and pinion, holding panel accuracy at ±0.1 mm

Flexible rubber-padded gripping structure clamps panels down to 34 × 45 mm, so small offcuts stay put instead of being rejected

Air-cushioned ball table lets jumbo sheets slide with minimal effort and without scratching the surface

Tuodiao control software on an industrial PC with open data ports: imports cutting lists from order-splitting and nesting software, with optional Tuodiao optimisation software

Overview

The TD-420 has the longest working travel in the Tuodiao CNC beam saw range: a 4200 mm cutting length combined with a 120 mm cutting thickness. It takes jumbo engineered boards that shorter beams cannot position, and cuts taller stacks per cycle when the order mix is dominated by standard formats. Like the rest of the range it positions, clamps and cuts automatically once a cutting task is entered or imported, holding ±0.1 mm panel accuracy.

Structure and Accuracy

The 15 kW main saw and the 2.2 kW scribing saw are driven by separate motors: the scribing saw first cuts a shallow groove into the underside of the panel and the main saw follows, which prevents chipping on the back face of double-sided laminated boards. The clamping beam and the main saw raise and lower automatically according to cutting thickness, so an operator does not re-set the machine between different board stock. The carriage is servo-driven and returns at up to 120 m/min. Feeding uses a manipulator built on a high-precision reducer with ground rack and pinion. The rubber-padded gripping structure can clamp panels as small as 34 × 45 mm, so small offcuts are still held along the cut line, while the air-cushioned ball table keeps jumbo sheets easy to slide and protects the panel surface.

Software and Line Integration

The control system runs on an industrial PC with Tuodiao’s own cutting software and open data ports. It imports the cutting list of a cabinet order from a wide range of order-splitting and nesting programs, optimises board yield and records the result, which digitises the cutting stage; Tuodiao optimisation software can be added. With its 4200 mm travel the TD-420 works as the sawing station of a cutting line, linking with front or rear loading manipulators, a board store and the downstream edge banding and drilling workstations for continuous production in custom and panel furniture manufacturing.
