TDL Half‑Lap Jointing Machine

Rapid, tear‑free half‑laps for perfect glazing‑bar cassettes.

Why Choose the TDL?

Built for uncompromising joint strength and speed:

  • One‑Pass Half‑Lap Perfection – Three high‑speed spindles cut the V‑notches and the half‑depth cross‑cut in a single cycle, delivering crisp, interlocking joints every time.

  • No Profile Tear‑Out – Workpiece is milled on all three sides while firmly clamped, eliminating grain breakout on fully profiled bars.

  • Self‑Centred Accuracy – Adjustable self‑centring clamp aligns material automatically, so every joint sits dead‑centre without manual adjustment.

  • Foot‑Pedal Efficiency – Pneumatic clamps engage and the cycle starts with one tap, boosting throughput and operator safety.

Ideal for:  Traditional & simulated divided light (TDL/SDL) bars • decorative cabinet grids • timber window grilles

How it works

  1. Load & Align – Operator slides the bar along the flip‑stop into the self‑centring clamp.

  2. Clamp & Start – Foot‑pedal activates two pneumatic hold‑downs and begins the machining sequence.

  3. Dual 45° V‑Notches – Twin 24,000 rpm spindles plunge to cut opposing V‑notches.

  4. Half‑Depth Cross‑Cut – A third spindle traverses across the bar at exactly 50 % depth to complete the lap.

  5. Auto‑Return – Heads retract and table returns to start, ready for the next bar.

From our workshop in West Sussex, we mill and assemble every spindle and run every acceptance test before a machine leaves the door. Each unit ships with the correct voltage, CE paperwork and a plug‑and‑play starter tooling pack—so customers from Melbourne to San Francisco can uncrate and start cutting right away.
