How to Choose the Right Grinder/Notcher for Your Metalworking Needs

Posted by Scotchman Industries on Thursday, April 20, 2023

  Grinder/Notchers available from Scotchman Industries

If you are looking for a versatile and efficient machine that can perform both grinding and notching tasks on various sizes and shapes of metal tubes and pipes, you might want to consider a grinder/notcher. A grinder/notcher is a machine that can grind the surface of a metal tube or pipe to smooth out any rough edges or burrs, and also create notches or grooves along the tube or pipe to prepare it for welding. A grinder/notcher can help you save time and money by eliminating the need for separate grinding and notching machines, and by producing gap-free fits that are ready for welding.

But how do you choose the right grinder/notcher for your metalworking needs? There are many factors to consider, such as the grinding capacity, the speed, the ease of setup and operation, the safety features, and the price. In this blog post, we will introduce you to four models of grinder/notchers from Scotchman Industries, a leading manufacturer of metal fabrication equipment since 1967. We will compare their features and benefits, and help you decide which one is best suited for your specific applications.

Scotchman’s Grinder/Notchers: Four Models to Choose From

Scotchman’s grinder/notchers are constructed with a heavy-duty base and frame and are available in four models with different grinding capacities and speeds. Each model operates smoothly with minimal vibrations and produces gap-free fits ready for welding. Scotchman’s grinder/notchers are designed for easy setup with one vise that can hold all sizes of tube and pipe that is graduated in degrees and is equipped with a mandrel with centerline adjustments. Tool-free belt and mandrel changes make transitions quick and easy. Each model comes with two belts and two pipe mandrels. Optional mandrel sizes are available in a variety of sizes to ensure a gap-free fit.

The four models of Scotchman’s grinder/notchers are:

AL100U-01: This model has a grinding capacity range from 1/2” up to 3” O.D. It is equipped with a hand lever feed handle and a manual vise that can be adjusted right or left. It is ideal for light-duty grinding and notching tasks.

AL100U-02: This model has the same grinding capacity range and belt speed as the AL100U-01, but it is equipped with two handwheels instead of a hand lever feed handle. The two handwheels allow for more precise control over the grinding depth and angle. It is suitable for medium-duty grinding and notching tasks.

AL150: This model has a larger grinding capacity range from 1/2” up to 4” O.D.. It is equipped with a two-axis precision crossfeed table with both handwheels and a hand lever feed handle. The crossfeed table allows for more versatility and accuracy in grinding different shapes and profiles of tubes and pipes. It is ideal for heavy-duty grinding and notching tasks.

AL150-HS: This model has the same grinding capacity range and crossfeed table as the AL150, but it has a higher belt speed. It also has an additional high-speed parts grinder in the back. It is perfect for stainless steel and aluminum grinding and notching tasks, as well as high-volume production.


How to Decide Which Model is Right for You

To decide which model of Scotchman’s grinder/notcher is right for you, you need to consider your specific metalworking needs, such as:

• The size and shape of the tubes or pipes you need to grind or notch
• The material type and thickness of the tubes or pipes
• The frequency and volume of your grinding or notching tasks
• The level of precision and quality you require
• Your budget.

As a general rule of thumb, you should choose a model that has a larger grinding capacity range than the size of your tubes or pipes, so that you have some room for adjustment. You should also choose a model that has a higher belt speed than the hardness of your material type, so that you can achieve faster and smoother results. You should also consider the ease of setup and operation, the safety features, and the warranty of each model.
