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
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.
With over 10 years’ experience in CNC and general machining services, Firstpart is one of the best rapid prototyping and CNC machining services in China. Here’s why:
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 milling involves the use of a high-speed rotary tool or drill to remove material from a block while the workpiece is held securely in a jig or vice. In CNC milling operations, the mill head may move in 3-5 axes relative to the material, cutting the workpiece in a manner directed by the CAD/G-code while the workpiece remains stationery.
Our CNC milling process is capable of 3-axis (x,y and z), 4-axis and 5-axis (x,y,z, A and B) milling for high speed cutting of engineering-grade materials into product prototypes and precision end-use parts. We also have indexed and continuous 5-axis milling process to achieve even more complex cuts and part design.
The operational capabilities of a CNC milling machine include cutting flat and shallow surfaces, deep cavities, flat-bottom cavities, slots, threads and more into any workpiece. The level of precision and capability varies with the number of axis in the mill. The typical configurations include:
3-axis CNC mills
These are the most common types of CNC mills. They machine parts with the use of the primary X, Y and Z axis.
4-axis CNC mills
These type of CNC milling machines allows for additional rotation of the workpiece on the vertical axis to allow more continuous operation.
Indexed 5-axis CNC milling
5-axis, also known as 3+2 axis CNC machines are milling centres developed to lower the setup time of having multiple orientations. During operations, these mills can rotate the tool head and/or the bed to access the workpiece from another angle.
Continuous 5-axis CNC milling
The continuous 5-axis CNC milling machines are similar to the indexed setups. They allow the movement of all axis (X,Y,Z, A and B) concurrently during machining. It allows for continuous movement that enhances the accuracy and the cut and allows for parts with complex geometries to be manufactured.
Other benefits of CNC milling
CNC mills can perform value-added services with high precision and scalability. This makes them an ideal candidate for low-volume production runs, rapid tooling and rapid prototyping. Their material diversity also makes them a great fit for use across any industry.
Performed on a lathe, CNC turning will produce parts by rotating the workpiece at high speeds around a stationary cutting tool till the desired form is attained. The process involves the securing of a material bar in a chuck while rotating them to a cutting tool to strip the original workpiece of material. The cutting tool will typically move along the X, Y and Z axis relative to the part.
CNC turning is more cost-effective than CNC milling. This is because of their rate of production and suitability for larger parts.
The ideal CNC turning centre will have more than one turret. The turning operation can be completed faster when there is a main spindle and sub spindle. The turning action will entail the main spindle machining the part to a considerable extent before passing it off to the sub spindle to complete the remainder operations.
After the part has been machined, deburring often follows. The part may then be transferred to a mill to add certain features that may not be possible on the lathe.
CNC turning can be performed with a number of techniques. Depending on the type of part, geometry and end-use, First Part can create CNC turned parts with any of the following methods:
Depending on the model, CNC lathes are capable of high-speed turning and milling. These machines are available at First Part to help handle the complexity and freedom required for the entire CNC machining process.
Advanced CNC turning capability that allows speciality CNC lathes machine up to three or four workpieces simultaneously. A key feature is the flexibility around the path and axis to enable synergy in the part movement.
This type of turning technique is ideal for the manufacturing of small, medium size, high-precision components and parts. Swiss equipment and parts are often manufactured to serve the medical/dental industries. They are capable of making multiple parts within the same manufacturing cycle.
CNC turning centres can create round/cylindrical parts accurately, affordably and flexibly. CNC turned parts have excellent repeatability, scalability and diversity in applications. They are suitable for a range of process including threading, knurling, drilling and boring.

Machined parts are left as manufactured. There will be visible tooling marks on the part.
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.
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.
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.
Electroplating (such as Nickel plating) is used to improve the strength and durability of metallic parts.
An electrochemical process used to remove some material from the finished workpiece in order to reduce surface roughness and enhance the surface finish.
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.
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.
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 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.
An array of custom finishes are also available for your part depending on material and purpose of the end-use part.
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.
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.
CNC machining, through milling, turning, kneading, knurling, cutting, sanding and grinding can be used to manufacture high-quality parts with tight tolerances and exceptional degrees of precision, accuracy and functionality.
CNC can be used along with other technologies in making highly detailed and accurate tooling parts for the manufacturing of large-volume parts. CNC may also be used in the creation of injection molding molds, die-casting molds and other master patterns.
