Metal Machining

CNC Machining Metal

We offer a full range of CNC (Computer Numerical Control) metal machining services. Our metal milling services can be used to create part prototypes or small batch runs.

CNC machining is a manufacturing process that involves using high speed, computer-controlled, precision machines to remove plastic or metal from a blank, a block of metal or plastic, to create a part. The process is subtractive, meaning the machine removes material from the blank to reveal the final part. Since the machine is computer controlled, the process is highly repeatable, resulting in the same identical part each and every time.
How CNC Metal Machining Works
A CNC machine is given a specific set of code. The code tells the machine where and how to cut material from the blank. The CNC machine code contains a list of instructions on how to create the part. The instructions are part of a Computer Aided Design (CAD) file that contains the code needed to create the part. The code will first tell the machine where to place the tooltip, then how fast the tooltip should spin, and finally to what coordinates the tooltip should move. CNC machines use coordinates on a set axis. We use multi-axis CNC machines, allowing parts to be cut on the X-, Y-, and Z-axes. CNC machines cut parts with extreme precision. Since the machine is computer controlled, each successive part will be exactly the same as the first, making replication fast and easy.

Benefits of CNC Machining
CNC Prototyping
Our CNC metal milling services can be used to create prototype parts to ensure fit, form, and function before heading into full-scale production. Part prototyping allows manufacturers to test new parts and make necessary changes before moving on to mass production. CNC metal machining is quick, relatively inexpensive, and allows customers the opportunity to get their hands on a part without the expense or time required to make a full production run. Changes are cheap and easy to make – just make the design changes to the model and our CNC milling shop will have the revised part ready for testing.
Small Production Run
Our  CNC milling services are ideal for small production runs. All that is required is a CAD file – no costly moulds, no extended production times. Parts are cut out directly on the CNC machine and will be ready to use immediately. Our CNC milling shop can have a small production run done and out the door within a few days.
Form, Fit, and Function
Our CNC metal machining provides manufacturers the opportunity to test a part for form, fit, and function before committing to a final design and entering into mass production.

The Form
CNC metal machining is a precise process and provides exact repeatability. The computer-controlled machine tools all move precisely and simultaneously on their axes to create complex, three-dimensional shapes that would be almost impossible or incredibly time consuming with manual machining. These qualities make CNC metal machining a good manufacturing process for jobs that require a high level of precision or repetition.

The Fit
CNC metal machining is ideal for manufacturers that require tight tolerances. Our CNC milling shops hold tolerances to within +/- 0.002 in. (0.05 mm) for metal parts. Customers can specify tighter tolerances on critical areas of the part.

The Function
The material being used is just as important as the design. CNC metal machining from We allows manufacturers to test prototype pieces as they would the final production parts. We specialize in custom aluminum machining as well as machining a long list of other metals. Parts made with CNC metal machining are immediately ready for use and can be subjected to any required testing conditions.

Types of CNC Machines
CNC machines are purpose-designed and built to do a specific job. The varying CNC machine designs allow Our CNC milling shop to meet the demands of any customer. We have several CNC machines, each with its own functionality to machine different types of parts in different ways.
CNC Mills
CNC mills are the most common type of CNC machine. This machine starts with a block of metal called a blank. The CNC machine removes material until only the desired part is left. The cutting tool can be directed across a three-axis system. The X-, Y-, and Z-axes are used to cut height, width, and depth from the part. The CNC machine follows the coordinates from the CAD file in order to produce the finished part.

CNC Lathes
CNC lathes can also be used for CNC metal machining. When CNC metal machining is done on a lathe, it is referred to as turning. The CNC lathe operates along the same lines as the CNC mill. While the CNC mill holds the block in one place, the CNC lathe spins the blank at a high RPM. The computer then uses a cutting tool to remove material from the spinning blank. CNC lathes are ideal for creating cylindrical pieces. Lathed parts will have uniform cuts on all sides. While a CNC mill can cut across thee axes, the CNC lathe uses a two-axis system, only removing material from the X- and Y-axis.
CNC Plasma Cutters
CNC plasma cutters are another way to create custom CNC milled pieces. The plasma cutter operates along the same concept as any other CNC machines. Like a CNC milling machine, the plasma cutter uses a plasma torch to remove pieces from a metal blank.  However, the CNC plasma cutter is designed to cuts parts out of a large, flat metal piece instead of a metal block. The blank is laid flat and the plasma cutter removes the desired material. The CNC plasma cutter tool operates on a two-axis system, along the X- and Y-axis. This is similar to a CNC lathe but the metal blank is held stationary and does not spin.

CNC Metal Machining Review
Our CNC metal machining offers customers a precise and repeatable way to manufacturer prototype parts or small production runs. Before committing to CNC metal machining, there are several variables to consider. The hardness of metal will affect the length of time required to machine the part. Harder metals, like carbon steel, require a slower cutting speed. A slower cutting speed will take more time to remove material from the blank. Custom aluminum machining can be done nearly four times as fast because aluminum is a softer material. The type of metal can also greatly affect the final cost. Be sure to consider the type of metal and its cost when doing preliminary price estimations.CNC metal machining is an ideal manufacturing process for small runs of metal parts, especially when dealing with prototypes or low volumes.

We offer several secondary processes for CNC machined components. After the metal part is machined, it can be sent for anodizing, plating, or powder coating.We specialize in custom aluminum machining but can easily work with a variety of metals to satisfy customer needs.
