Marshall Industrial Technologies has been serving clients for seven decades and understands the changing needs of the industrial community. In our 30,000-square-foot machine shop, we’re equipped with machinery and technical skills to meet those needs, and our team of machinists and fabricators operate 24 hours a day, seven days a week to provide efficient service. We manufacture replacement and spare parts, often more quickly than the original manufacturer can have them delivered to you.

We’re proud to offer a wide range of machine shop fabrication services and deliver high-quality custom solutions.

Machining vs. Welding & Fabrication

It’s important to note the difference between machining, welding, and fabrication. The production processes themselves are distinct, and they start with differently shaped materials and finish with different levels of precision. With machining, pieces are taken away from the starting material; with fabrication and welding, pieces are added to the material.

All types of metals are used in both processes. For ceramics and most plastics, machining is the best option, while fabrication is effective for non-ceramic composite materials. Additional materials like glass or plastic may be added later to the finished product via a different process.


Material is removed from a solid round bar, tube, or plate via a variety of processes, including milling, drilling, and turning. Machining offers greater precision than fabrication—CNC machined parts can have tolerances as small as +/- 0.0002. Our machining services include:

  • Turning: up to 60 inches in diameter on our 24′ engine lathe or up to 6 feet in diameter on vertical turret lathe
  • Line Boring: up to 10 tons on our vertical turret lathe
  • Surface & Blanchard Grinding: up to 48 inches in diameter
  • Broaching: up to 2 inches wide by 10 feet in diameter
  • Milling
  • Drilling


With metal fabrication, techniques such as bending, punching, cutting, and welding are used to build parts from plate and formed, or expanded materials. CNC precision fabrication allows for tolerances as small as +/- 0.005. Depending upon the application, that may be enough, which is why fabrication is a popular cost-effective choice for certain products on small, medium, and large production runs.


With extreme heat and/or the use of other metals or gases, two pieces of metal are joined together. There are a variety of welding processes, including stick welding (SMAW), MIG welding (GMAW), Flux Cored arc welding (FCAW), tungsten inert gas or Tig welding (GTAW) and Orbital Fusion welding.
