Aluminium T-Slot Machine Bed 20 x 40 mm – Grooved Tooling Plate, NZ Made

An aluminium T-slot machine bed profile, 20 × 40 mm, designed and extruded by us here in New Zealand. It's purpose-made as an adaptable bed for CNC routers, engravers, 3D printers, jigs and general work holding — whatever you need to clamp, locate and build on.

Compatible with both our hardware series

One face is designed to take our standard 40 series spring nuts, nut plates, T-bolts and work clamps. The other face and the sides take our 20 series hardware — so you can fasten and clamp from every surface.

Typical uses

• CNC router, engraver and laser machine beds
• 3D printer frames and beds
• Fixture plates and tooling plates
• Work holding, clamping and jigs

Mill finish (raw)

Supplied in a mill finish rather than anodised. Being raw, you can mill the top surface perfectly flat once it's mounted on a router bed — and it keeps the cost down. This profile has occasional perpendicular lines, blemishes and scuff marks; these are random and are part of how we keep the price low.

Cut to your length

Choose a stock length above, or select Custom Cut Length and enter the length and quantity you need.

• Lengths 100–3000 mm: cut to +/- 0.5 mm
• Other lengths: cut to +/- 1 mm
• Every piece of a given length is cut identically, clean and square

(For custom cut lengths, the correct total — a cutting charge plus the extrusion cost — only shows once you reach checkout, not in the cart.)

Cutting it yourself

Aluminium extrusion cuts cleanly with a standard drop saw or mitre saw. Use a sharp, fine-tooth blade and a little light oil, CRC or kerosene for a clean cut.
