Douglas Machine & Engineering specializes in developing industrial design solutions for demanding industries. We complete every phase of the fabrication process in-house, saving our customers’ time and money. Whether the project involves developing fully integrated units or retrofitting new units into current systems, our team of industrial designers ensures correct placement and functionality. 

As an ISO 9001:2015 and AS9100D-certified company, we deliver reliable solutions that have been properly tested and installed on-site. Whether your project is large or small, Douglas Machine & Engineering can handle it. Our facility is capable of moving fabricated parts up to 20 tons and machining small parts up to 20,000 lbs. Our parts feature average tolerances ranging from +/-.005 to +/-.0005.

What Types of CNC Machining & Fabrication Services Are Available?

Computer Numerical Control (CNC) machining is a type of manufacturing process where preprogrammed computer software directs the movements of machining equipment. Since the process is controlled automatically by a computer, the finished workpieces are extremely accurate and generate significantly reduced waste. CNC machining allows for projects to be completed quickly, accurately, and cost-effectively. 

At Douglas Machine & Engineering, we provide an extensive selection of CNC fabrication services, including:

  • Milling: Milling is the process of drilling and cutting materials using a rotating cylindrical tool. Milling machines come in several types and can move along several axes to cut from a variety of angles. In vertical mills, which are three-axis machines, the spindle is attached to a vertically oriented arm, and the table moves along a Z-axis to meet it. Horizontal mills work similarly, however, with the spindle horizontally oriented. Horizontal mills are ideal for large or heavy workpieces. 
  • Grinding: Grinding machines use a rotating wheel to precisely remove pieces of metal. They are frequently used as a finishing process when creating cylindrical-shaped objects. However, they can be used on many other types of workpieces. Grinding machines come in several types, but they all deliver extreme precision. When using a CNC grinder, a technician will enter precise measurement specifications into a computer, and then the machine will create the final product. 
  • Lathes: These machines rotate a workpiece around a stationary cutting tool to produce precise, symmetrical shapes. Lathes operate on two or three axes and come in several configurations, including horizontal, vertical, Swiss-type, and more. Lathes are highly versatile and can be used to machine many types of workpieces. In certain situations, they can eliminate the need for further processing entirely. 

In addition to these services, Douglas Machine & Engineering also utilizes assembly fixtures to optimize machining processes. Assembly fixtures are supportive devices that increase the production speed and quality of identical parts. They hold components together in a precise alignment to increase the ease and efficiency of production.
