Almi AL100u-01 Abrasive Tube Notching Machine 415v
The AL100U-01 is a versatile tube notching machine, operated via a lever for straightforward and efficient use. Capable of grinding materials ranging from Ø20 to Ø76.1, it features an infinitely adjustable cross support and a rotatable clamp, enabling precise grinding of all tube profiles at angles between 30° and 90°.
This machine is designed for square, rectangular, and round tubes with varying wall thicknesses and is suitable for all common material types. The ALMI belt adjustment system makes it simple to adjust the grinding belt using the supplied hex wrench, while quick-release functionality ensures rollers can be changed in seconds for maximum efficiency.
Equipped with a deburring table, the AL100U-01 allows for easy deburring of pipes after grinding, making it an ideal multifunctional tool for a range of applications. 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 is the Almi AL100U-01 abrasive tube notcher designed to do?
The AL100U-01 uses an abrasive belt and shaped grinding rollers to produce tube notches ready for fabrication and welding. It is operated with a lever and also includes a table for deburring prepared tube ends.
What diameter range can the AL100U-01 notch?
Selmach lists an outside-diameter capacity from 20 to 76.1mm. The appropriate grinding roller must match the intended tube size, and the material and wall thickness should be checked before use.
What notch angles can be set on the AL100U-01?
The adjustable cross support and rotatable clamp allow grinding angles from 30 to 90 degrees according to Selmach’s specification. Set and verify the required angle on a test piece before a production run.
How is the AL100U-01 operated compared with the AL100U-02?
The AL100U-01 uses lever operation. The AL100U-02 adds handwheel control as well as a lever, which can be useful where the operator wants a different feed-control method.
What abrasive belt and motor are specified for the AL100U-01?
The AL100U-01 uses a 100 x 2000mm abrasive belt and has a listed 3.0kW motor. The Selmach product page identifies the machine as a 415V model.
Can the AL100U-01 notch stainless steel and box section?
Selmach describes the AL100U-01 as suitable for common materials and for round, square and rectangular tube. Select the appropriate abrasive belt, roller and extraction arrangements for the specific material and finish.
What features help reduce setup time on the AL100U-01?
The machine has a quick-change grinding roller arrangement, adjustable belt tension and a deburring table. These features support changeovers between suitable tube sizes and help complete end preparation at one workstation.
How should the AL100U-01 be maintained and can Selmach service it?
Inspect belt wear and tracking, roller condition, the clamp, guarding and extraction before use. Follow the ALMI maintenance instructions and contact Selmach for parts, technical support and confirmation of any applicable Service Plan.
