CNC Process

CNC milling is a part fabrication technique carried out with the aid of a high-speed automated cutting machine designed to remove unwanted material from a part. CNC mills are available in various sizes, capacity and axial configurations. They can work with a variety of materials like plastic, resins, aluminium and more, but are specially designed for machining harder materials like stainless steel and titanium with high precision and accuracy.

CNC turning operations are designed for making final parts with axial and radial holes, internal diameters, grooves and slots. Our CNC turning centres are capable of high-speed turning of both plastic and metals to create end-parts with complex external geometries, cylindrical features, threads and internal bores.

Tolerance Of CNC Machining in First Part

Our precision CNC machining centres can manufacture small to large part sizes with tight tolerances and high precision. Our general tolerance limits for CNC machined metals and plastics is generally affected by the material type and the part geometry. See below our general tolerance limits for metal and plastic materials:

With our precision CNC machining machines, we may be able to achieve even tighter tolerances on individual parts. This is however subject to additional costs and price-per-part. Check our quality control information.

CNC Machining Finishing In First Part

CNC precision machining parts can be finished in many ways that may cover purely aesthetic finishes or offer some form of protection to the part. Finishes should beautify, enhance sophistication and functionality of any part. At Firstpart, our CNC-manufactured part maybe finished in any of the following options:

· Standard/As manufactured

Machined parts are left as manufactured. There will be visible tooling marks on the part.
 

· Bead blasting

A surface smoothing operation that involves the direction of fine glass beads at a part’s surface under high pressure. Bead blasting creates a smooth, uniform surface finish on the part.

· Sanding

A surface smoothing and polishing method done with the aid of a sandpaper or sand. The size of the pores in the sandpaper determines the type of smoothness achievable.

· Anodizing

An electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of the part. This can be used for decorative, anti-corrosion or surface hardness treatments. Anodizing is most common with aluminium parts.

· Painting

3D printed parts may be masked and spray-painted to any colour with automotive quality paints after sanding and polishing have been carried out to smoothen the surface.

· Chrome-plating

This involves the deposition of a thin chromium layer onto a metal part through an electroplating process. The chromium layer may serve decorative functions, make the part anti-corrosion or improve the surface hardness. 

· Plating

Electroplating (such as Nickel plating) is used to improve the strength and durability of metallic parts.

· Electropolishing

An electrochemical process used to remove some material from the finished workpiece in order to reduce surface roughness and enhance the surface finish.

· Brushing

Brushed machined parts have a satin-like, one-direction finish. It is achieved by using a grit belt or wheel, non-woven abrasive belt or pad to produce a polished finish in a metal part.

· Polishing

Used for creating high-quality surface finish in CNC machined parts. Before polishing, parts should be sanded and smoothed to ensure that final surface looks and fees as intended.

· Texturing

Texturing helps to enhance the ergonomics, cosmetics and weather resistance. It is used to give machined parts improved grip, reduce their slipperiness and mimic certain textures.

· Custom

An array of custom finishes are also available for your part depending on material and purpose of the end-use part.

What is CNC Machining

he term CNC widely refers to the “computer numerical control” technology that is used in the subtractive manufacturing process. CNC machining is a manufacturing technology involving the use of computer-aided controls and machine tools to remove layers/portions of a stock material/workpiece till a desired custom and final part is made from the workpiece.

At First Part, our CNC machining process is widely applied in new product development, rapid tooling, product prototyping and end-product manufacturing. It is suitable for use with an diverse range of plastic CNC machining materials & metal CNC machining materials (ceramic, plastic, wood, metal, composite, foam and glass), and can be used across a wide array of industries.
