CNC Machining FAQ
What is CNC Machining?
CNC is short for “Computer Numerical Control.” It describes an automated method of machining. A computer controls all the tools involved in the manufacturing process. It is then programmed with exact specifications to create the desired product. We use both Milling and Lathes. This method is rapidly replacing the manual method in which people control the various tool components. This is because it can create products with a much higher degree of precision and consistency.
What is the difference between CNC Machined Parts & 3D Printed Parts?
What process is better? CNC Parts are better at higher tolerance requirements but most machine shops running CNC equipment are very backlogged with work so can take anywhere from 2 to 6 weeks to produce a single part. 3D printing allows for quick production and is ideal for small to medium production runs.
What are CNC machines and how they work?
CNC machines are devices that cut material to produce a physical part. The process is called Computer Numerical Control and is based on subtractive manufacturing.
What are the advantages of CNC machines?
CNC machining produces little waste, Great accuracy, Fast and efficient production, Safe to operate, Reduced energy consumption, Low production costs normally
CNC Processes & Equipment
Our machine shop uses industrial mills like the HAAS DM-2 and HAAS EC400 Mill to create high quality parts.
CNC Turning Lathe
Our HAAS SL-30 and Trak 1840 Lathes machine precision parts for protoypes or large quantity orders.
Haas DM2 is a fast accurate mill with great abilities to get parts done quickly.
The DM-2 is a compact, high-speed machining center built with proven Haas components and sub-assemblies. It is identical in construction and specifications to the DM-1, with the addition of 8″ of X-axis travel and table length. The machine’s shop-proven 40-taper inline spindle, 18+1 tool changer, high acceleration rates, fast rapids, and impressive short tool-change times make the DM-2 an attractive high-productivity machining center.
CNC Material & Finishing Options
Selecting the correct material is a vital step in the project process. The ideal material option is highly dependent on your particular use case and needs. Because almost every material with adequate hardness can be machined, CNC capabilities have a very large range of material options to decide from. For engineering products, metals and plastics are most relevant. Surface textures can also alter the properties of CNC machined parts. Here is a list of materials & Finishes:
Stainless Steel 303
Stainless Steel 316
Stainless Steel 17-4PH
Alloy Steel 4340
Mild Steel 1045
Mild Steel A36
Tool Steel A2
As machined parts have the tightest tolerances because no extra operations are performed on the surface of the part. But marks following the direction of the cutting tool are still noticeable. The standard surface roughness of as machined parts is 3.2 μm (125 μin) and can be decreased down to 0.4 μm (16 μin) with further operations with finer end mills
Anodizing adds a thin hard, non-conductive ceramic coating on the surface of aluminum parts, increasing their corrosion and wear resistance. Critical areas can be masked to retain their tight tolerances. Anodized parts can be dyed producing a smooth aesthetically pleasing surface.
Powder coating adds a thin layer of tough, wear and corrosion-resistant, protecting polymer paint on the surface of a part. It can be used on parts of any material and is available in many colors.
Bead blasting enhances a uniform matte or satin exterior finish on the machined part, get rid of all tool marks. Bead blasting is mainly used for visual purposes, as the subsequent surface roughness is not guaranteed. Curcial surfaces or features can be masked to avoid any dimensional difference.
Hard coat anodizing
Hard coat anodizing creates a thicker, high- density ceramic coating that gives excellent corrosion and wear resistance. Hard coat anodizing is appropriate for functional applications. The typical coating thickness is 50 μm and, usually, no color is applied. Critical areas can be masked to retain their tight tolerances.
About CNC Machining
Precision Is Key
Precision in 3D printing is key. Even the smallest imperfection in one layer can cause defects in successive ones. A minor error can negatively impact the overall shape and functionality of the product. That’s why we commit to using CNC machining to ensure greater accuracy for your products.
It follows that the 3D printing process relies heavily on programs inspired by CNC machining. The printing process uses them to precisely add material in repeating layers. This creates the desired shape.
The key difference between 3D printing CNC programs and other types of CNC programs is that 3D printing is an additive process. In contrast, most others are subtractive. Subtractive programs might be a water jet cutter program, for example. Most other CNC manufacturing programs grind or cut objects to a specific shape.
There are many benefits to CNC machining. It increases production and product quality. More than that, it reduces the effect of human error. In the end, it can save manufacturers a lot of time and money.
In addition, CNC machines take up a lot less space than traditional machining equipment. At the same time, it requires far fewer people to reach the same outcome. This means you can do more work at a lower cost. The product made via this technology is less likely to have defects. It can save additional money and material.
By using CNC machining, we bring you all these time and cost-saving benefits and more. Plus, this method allows us to be flexible and adaptive to your unique needs. No matter the printing project, we aim to deliver the best.
Almost any automated tool can be configured to CNC machining. This includes laser cutters, lathes, water jet cutters, and even embroidery machines. Our tools can be programmed to cut complex shapes and angles. They can also create delicate designs. As is the case in 3D printing, we can lay material in almost any shape imaginable.
We can also reprogram the CNC code at any time. This can change the tool directions and output. What this means is that we can use one system to create an endless number of unique products. That way if you need to make any changes, we can do so with the simple push of a button.
