Almi AL100U-02 Abrasive Tube Notching Machine 415v
The AL100U-02 builds on the AL100U series with enhanced control via both a lever and hand wheels for greater precision. Designed to grind materials from Ø20 to Ø76.1, it features an adjustable cross support and a rotatable clamp, allowing you to achieve accurate grinding angles from 30° to 90° for all tube profiles.
Capable of handling square, rectangular, and round pipes with varying wall thicknesses, the machine works seamlessly with all standard material types. The ALMI belt adjustment system simplifies the process of belt adjustment and replacement, with the grinding belt tensioned and rollers swapped in seconds using the included hex wrench.
Complete with a deburring table, the AL100U-02 ensures pipes can be deburred immediately after grinding, making it a highly practical and multifunctional solution for workshop needs. We also offer a range of abrasive belts to suit.

- Length stop
- Dust Extraction System
The AL100u-01 is operated with a lever. With the AL 100u you can grind material from Ø20 to Ø76.1. The cross support and the slide with rotatable clamp are infinitely adjustable. This allows all tube profiles to be grinded at any desired angle from 30° to 90°. The AL100u-02 is the same specification as the 01, except it adds in additional handwheel operation for finer control.
The Al150u has a wider belt (150mm), and can grind material from Ø20 to Ø114.3, and is operated by either a lever or handwheel operation for greater precision.
Both machines grind square, rectangular and round pipes with different wall thicknesses and is suitable for all common material types. Thanks to the ALMI belt adjustment system, adjusting the grinding belt is now even easier with the supplied hex wrench. The grinding belt can be tensioned quickly and changing grinding rollers can be done in just a few seconds.
Fitted with a deburring table, when a pipe has been ground it can be easily deburred on the deburring table. This makes the machine truly multifunctional.

Frequently Asked Questions
What is the main advantage of the Almi AL100U-02 tube notcher?
The AL100U-02 combines lever and handwheel operation, giving the operator an alternative way to control the grinding feed. It is designed for accurate abrasive-belt notching of tube ends before welding.
What tube diameters can the AL100U-02 accommodate?
Selmach specifies a tube diameter range of 20–76.1mm for the AL100U-02. The selected grinding roller and clamping arrangement must suit the workpiece profile and size.
What is the grinding angle range on the AL100U-02?
The AL100U-02 supports grinding angles from 30 to 90 degrees using its adjustable support and rotatable clamp. Check the finished joint fit-up before running a batch of components.
How does the AL100U-02 differ from the AL150U?
Both offer lever and handwheel operation, but the AL100U-02 is listed for tube diameters up to 76.1mm with a 100mm-wide belt. The AL150U is listed for diameters up to 114.3mm with a 150mm-wide belt.
What belt size and motor power does the AL100U-02 use?
The published AL100U-02 specification lists a 100 x 2000mm belt and 3.0kW motor. Selmach markets this version as a 415V machine.
Can the AL100U-02 prepare rectangular or square hollow sections?
Yes. Selmach states that the machine can grind square, rectangular and round tube profiles with differing wall thicknesses. Check the clamping method and abrasive contact for the chosen section.
Is a deburring table included on the AL100U-02?
Yes. The AL100U-02 includes a deburring table, allowing operators to remove burrs after notching without using a separate dedicated deburring machine for every task.
What routine checks and Selmach support are recommended for the AL100U-02?
Check belt tracking and condition, roller wear, clamp security, guards and dust extraction in line with ALMI instructions. Selmach can advise on consumables, technical support and whether the machine qualifies for a Service Plan.
