Almi AL150U Abrasive Tube Notching Machine 415v
The AL150U offers advanced functionality and precise control with its lever and hand wheel operation. Designed for grinding materials from Ø20 to Ø76.1, it features an adjustable cross support and a rotatable clamp, enabling accurate grinding of all tube profiles at angles ranging from 30° to 90°.
This machine accommodates square, rectangular, and round pipes with different wall thicknesses and is compatible with all standard material types. Its efficient ALMI belt adjustment system allows for easy belt tensioning and quick roller changes using the supplied hex wrench, ensuring minimal downtime during operation.
The inclusion of a deburring table ensures that pipes can be deburred smoothly and efficiently after grinding, making the AL150U a reliable, multifunctional tool for demanding workshop environments. We also offer a range of abrasive belts to suit.

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 applications suit the Almi AL150U abrasive tube notcher?
The AL150U is intended for abrasive-belt notching of round and hollow-section tube for welded joints. Its wider belt and larger listed tube diameter range suit fabrication jobs beyond the AL100U models.
What tube diameter range does the AL150U handle?
Selmach’s technical specification table lists an outside-diameter range of 20–114.3mm for the AL150U. Confirm the exact roller size and intended profile with Selmach before ordering, as the page’s introductory text gives a smaller range.
What grinding angles are available on the AL150U?
The AL150U technical specification lists grinding angles from 20 to 90 degrees. The angle is set using the adjustable support and rotatable clamp, and should be checked against the joint design.
What size abrasive belt does the AL150U use?
The AL150U uses a 150 x 2000mm abrasive belt, compared with the 100 x 2000mm belts specified for the AL100U models. Select the abrasive grade to suit the material and surface finish.
How is the AL150U operated?
Selmach lists both lever and handwheel operation for the AL150U. The machine also has an adjustable cross support and a rotatable clamp for positioning the workpiece.
What motor power and supply does the AL150U require?
The AL150U is listed with a 4.0kW motor and sold by Selmach as a 415V machine. Check the machine nameplate and electrical installation before commissioning.
Can the AL150U be used for deburring as well as tube notching?
Yes. Selmach lists a deburring table on the AL150U, allowing the operator to clean prepared tube ends after grinding. Use suitable extraction and abrasive handling procedures.
What maintenance and service support does the AL150U need?
Follow ALMI instructions for checking belt tension and tracking, rollers, clamping, guards and extraction. Selmach can advise on replacement belts and rollers and confirm whether a Service Plan is available for the specific machine.
