Name Detail
Maximum Part Size 78.74in. x 59.05in. x 39.37in.
2000mm x 1500mm x 1000mm
Distance Dimensions For features of size (Length, width, height, diameter) and location (position, concentricity, symmetry) +/- 0.005”.
Precision Tolerances ±0.1~2mm depend on part size
Minimum Feature Size 0.020” (0.50 mm). This may vary depending on part geometry and chosen material.
Threads and Tapped Holes We can accommodate any standard thread size. We can also machine custom threads; these will require a manual quote review.
Edge Condition Sharp edges will be broken and deburred by default. Critical edges that must be left sharp should be noted and specified on a print.

Finish Description
Anodizing Corrosion-resistant ceramic additions are added to the surface of machined parts, which can be dyed in different colors, most commonly clear, black, red and gold.
Sandblasting Sandblasting is the process of adding a uniform matte or satin surface finish to machined parts, removing tool marks, primarily for visual purposes
Powder Coating This is a process in which powder coatings are sprayed onto parts and then baked in an oven to create a strong, abrasion- and corrosion-resistant surface, and is available in a wide range of colors.
Electroplating A process that utilizes an electric current to reduce dissolved metal cations so that they form a thin metallic layer on the motor. Helps to place corrosion and improve wear resistance, electrical conductivity, reflectivity and aesthetics
Polishing
Brushing Brush coating can be used for a variety of purposes on plastic parts, such as cleaning, edge blending and deburring. It is the best way to protect the surface from damage and scratches.

How CNC Milling Works

The components of a CNC mill include: end mill & tool holder, tool changer, tool carousel, spindle, 2-axis milling head, air/coolant supply tubes, fixture, work piece, tool setter, x- and y-axis table.

We have multiple tool sets based on efficient cutters for a particular plastic or metal material. The machine then rapidly mills parts out of the block in a subtractive manufacturing process that uses 3- or 5-axis milling.

Machined plastic parts are left as-milled, which typically means they show visible tool marks. Some metal parts allow more finishing choices. When the run is complete and your required surface finish is applied, parts are boxed and shipped shortly thereafter.

FAQs of CNC Milling

What are the limitations of CNC milling?

The general limitations of CNC milling are prototypes size, axis movement, and drill bit size. The size and shape limitations will vary by the machine used.

Simple parts may only take hours to produce. However, complex parts requiring 5-axis CNC machining may take weeks. It may take hours to produce. But it requires 5-axis CNC machining may take weeks.

CNC milling machine alternative is laser cutting. The production variant with laser cutters allows you the highest precision with low maintenance costs.
