Metal Parts CNC Machining Service

CNC Machining, short for Computer Numerical Control machining, is a widely adopted

manufacturing process utilizing automated, high-speed cutting tools to shape metal or plastic

stock into desired designs.

The standard CNC machine types encompass 3-axis, 4-axis, and 5-axis milling machines,

lathes, and routers.

The method of cutting CNC parts can vary, with options such as keeping the workpiece

stationary while the tool moves, holding the tool in place while the workpiece rotates and

moves, or simultaneous movement of both the cutting tool and workpiece.

Experienced machinists operate CNC machines by creating tool paths based on the final part's

geometry, which is derived from a CAD (Computer-Aided Design) model.

CNC machines exhibit exceptional precision and repeatability, capable of cutting nearly any

metal alloy and rigid plastic.

This versatility makes custom machined parts suitable for various industries, including aerospace,

medical, robotics, electronics, and industrial applications.

Product Details

The CNC machining process predominantly employs metals as its primary materials.

These metals encompass alloy steel, carbon steel, cast iron, stainless steel, aluminum, copper,

magnesium, and zinc.

Nonetheless, this versatile process can also be applied to machine plastic components and work

with an array of other materials, including ceramics, composites, thermoplastics, and thermosets.

Post-processing and surface finishes for CNC machining

CNC-machined parts as they emerge from the machine often exhibit visible tool marks,

a feature that may not align with your specific part requirements.

Fortunately, there exists a multitude of post-processing techniques aimed at enhancing the

surface appearance and elevating attributes such as wear resistance, corrosion resistance,

and chemical resistance.

Methods like anodizing, bead blasting, and powder coating present viable options for refining

the final presentation of your custom parts, allowing you to achieve the desired surface

quality and performance characteristics.

Specialist Industries

Parts produced by this type of machining are commonly found in the automotive, aerospace,

medical, marine, and hydraulic industries.

Such as headers, housings, shafts, shells, knobs, rotors, terminals, fittings, pistons, valve stems,

and similar products.

FAQ's

1. What tolerances can achieve?

Tolerances are not universally fixed and vary depending on the specific processes and materials

involved. The final tolerances for your part are influenced by several factors, including:

1. Part Size
2. Design Complexity
3. Number, Type, and Size of Features
4. Material(s) Used
5. Surface Finish Requirements
6. Chosen Manufacturing Process

Upon order confirmation, we conduct a Design for Manufacturing review of your design.

This review helps identify areas that may require adjustments to enhance manufacturability.

It's beneficial if you can specify which areas in your design have critical tolerances that must be

met and which can be adjusted slightly if necessary to optimize production time and cost.

Below are some general tolerance guidelines:

General tolerances for CNC machining in metal and plastic
Tolerances for plastic injection molding
Reference charts for CNC machining materials and plastic injection molding materials
General tolerance for metal 3D printing is +/- 0.5mm
A shrinkage rate of +/- 0.15% is typical for vacuum casting

To ensure precise adherence to your manufacturing and technical specifications, all requirements

should be clearly detailed in the 2D drawings.

2. How quickly can I get my parts?

We can produce high-quality parts in as little as two weeks if you furnish us with comprehensive

2D and 3D CAD models.

However, for more intricate parts with additional requirements or special features, the lead time

may be longer. Feel free to request a quote to obtain precise lead times tailored to your project.

In terms of shipping, the majority of our shipments are dispatched via air freight.

The transit time from China to Europe or North America typically takes a few days.
