JCRAPID CNC milling scene

CNC Milling

During CNC milling, the workpiece is held stationary directly on the machine bed or in vise, material is removed from the workpiece using specialized cutting tools that rotate at a very high speed. WIth our 3-axis, 4-axis & 5-axis CNC machines, you can get milled parts with tight tolerance up to 0.01mm (±0.0004 in.)

CNC Turning

CNC turning can produce parts with a cylindrical profile at a much higher rate and a lower cost per unit than CNC milling. During CNC turning the workpiece is held on the spindle while rotating at high speed, a Cutting tool traces the outer an inner perimeter forming the geometry.

Standard Tolerances for CNC Machining in JCRAPID

Precision is key in many industries. If you have a product that must fit with or in another part to create a finished part, then machined tight tolerances are imperative. CNC machined product adheres to the measurements needed for processes after order completion.Sure thing is we can provide more tighter tolerance as well, if you have special requirements, please contact us.

Materials for Custom CNC Machining Parts

Materials used for custom CNC machining will vary by application. The precision of our process is certainly able to handle many types of materials. The cost of certain types of material, such as plastic is less expensive to purchase. Depending on the use of the product a stronger material, such as metal, may need to be used. Thus, we machine a wide array of materials.

Trusted CNC Machining Services

Count on us to provide you with CNC machining services to facilitate your project seamlessly. Our qualified professionals can assist you with turning services, machining services, and more. Our CNC turning services and CNC milling services are second to none.

Wide Range of Surface Finishes for You

Choose multiple surface finishes for your machined parts. Add finishes to protect your custom CNC parts from harsher environments.

As-MachinedWe can hold machined surface roughness tolerance from 3.2 – 16 mm. This does not provide a protective barrier to environmental effects such as rusting.
AnodizedThere are varying types of anodized. This is a colored finished and the chosen will define the type.
Powder CoatThis is more resistant to chipping than regular paint. The color is retained and the powder coat has much thicker layers than wet paints.
PassivationThis finish uses nitric or citric acid and removes free iron from the surface. It protects the surface with a chemical for functions as a rust preventative.
Titanium AnodizeThis surface finish changes the oxide layer in a titanium surface using an electric current. If it is not treated after machining, it will create titanium dust when rubbed together.
ElectropolishingThis provides a brighter finish for the machined surface. It is used to polish or deburr metal parts.
ElectroplatingElectroplating is the process of applying a thin layer on the surface of the part. Electroplating can improve the corrosion resistance, wear resistance and appearance of the parts. There are different types of plating, including nickel plating, chrome plating and gold plating.
Heat treatingHeat treating can improve CNC parts hardness, strength, and toughness and other mechanical properties. Common heat treatments including AnnealingTempering, Hardening, high frequency heating, stress relieving and so on.

Milled parts can be machined up to 2000 x 1500 x 200 mm (78.7 x 59.0 x 7.8 in.)  For 3+2 axis and 5-axis milling, the maximum part size is 350 x 350 x 300 mm (13.8 x 13.8 x 11.8 in.). The maximum diameter for CNC turning is 431 mm (17 in.),  length is 990 mm (39 in). The minimum part dimensions recommended are around 0.39 x 0.39 x 0.39 in. (10 x 10 x 10 mm). The minimum for feature dimensions is 0.5 mm. We are limited to a 1000 mm (39 in.) maximum size for parts on our platform. You can place the request through your account manager if you need higher dimensions.

We perform full rang of CNC machining services, which including CNC milling, 5-axis CNC milling, turning and Swiss screw machining.

If your parts are low-volume production quantities and you need fast lead times, for example Volume: 50-2,000+ parts, then you are in the right place.Contact us to get your cnc rapid prototyping projects started today.
