2020 Aluminum Extrusion 1000mm Black (10Pcs/Pack) V-Slot Aluminum Profile European Standard Anodized Linear Rail for 3D Printer,CNC and Laser Engraving Machine

Very strong/stiff good quality.

Very good value

Amazing value for money. It's as described l, a 2020 aluminium profile and extra long. I am using these to make a large box to hold a laser engraving machine. Superfast delivery and exactly what I needed.

I'm giving it 4 stars because it is 0.4mm longer than 800mm. No bending and come well packed.

Does exactly what you want. Rigid and strong.

As the title says, these have not been cut square. Ends are off by just over 1 degree, making these not fit for purpose (unless you wanted a wonky, out-of-square frame!) Unfortunately I’ve already tapped the ends of some, so probably can’t return them now.

Nice enough in most respects, but dimensionally inaccurate. Whilst there are only loose industrial standards for these profiles, we do do expect at least a slot of 6mm in width. These have slots of 6.4mm meaning that so many T-nuts are left hanging on only by the skin of their teeth. Certain sprung nuts will not secure as the depth is greater than required.

Cut square, straight, correct dimensions, unacceptable amount of shavings in the package. Thanks for giving me 20 minutes of banging chips out of them and vacuuming.

Erste Bestellung exakt 300 mm, zweite Bestellung 300 mm und nun bei der dritten Bestellung gut 298 mm und als Zugabe gab es reichlich Sägespäne. Das genaues Schneiden möglich ist haben die ersten beiden Bestellungen ja gezeigt, da war wohl ein Knick in der Linse oder ein Dopplereffekt der die Sicht trübte ( mir als Brillenträger durchaus bekannt ). Da kann man nur sagen Danke für die Schlitze zum durchsehen .
