Custom Online CNC Machining Services

CNC machining involves the use of CNC tools and machines, which are operated and controlled through CNC machining language, typically G code. This language directs the CNC machine tool to specific Cartesian positional coordinates while managing aspects like tool feed speed, spindle speed, and additional functions such as tool changing and coolant application.

To address your manufacturing requirements, we offer immediate quotes for over 100 types of metals and plastics, allowing you to compare costs across different machining materials efficiently.

  • Aluminium alloy
  • Stainless steel
  • Orichalcum
  • Titanium
  • Plastic

Aluminium alloy

Aluminum is a highly ductile metal, making it easy to machine. The material has a good strength-to-weight ratio and is available in many types for a range of applications.

  • Lead time:<7 days
  • Tolerance: +/-0.01mm

Stainless steel

In many industrial production processes, stainless steel can provide satisfactory corrosion resistance and other excellent characteristics. The performance advantages of stainless steel: high strength, high temperature resistance, corrosion resistance, beautiful surface and so on; It can be applied to many fields.

  • Lead time:<7 days
  • How: = + / - 0.02 mm


The mechanical properties and wear resistance of brass are very good, and can be used to manufacture precision instruments and parts of ships. In general, the amount of precision copper parts such as auto parts, medical parts, electrical parts is more.

  • Lead time:<7 days
  • How: = + / - 0.05 mm


Titanium products have the advantages of light quality, high specific strength, good corrosion resistance, etc., so it is widely used in the automobile, aircraft, medical industry, the use of titanium alloy is mostly engine system software.

  • Lead time:<7 days
  • How: = + / - 0.02 mm


With the rapid development of the plastic industry and the continuous improvement of plastic properties, plastic parts have been more widely used, plastic parts are replacing traditional metal parts in different fields, a reasonable design of plastic parts can often replace a number of traditional metal parts, so as to achieve the purpose of simplifying product structure and saving manufacturing costs.

  • Lead time:<7 days
  • How: = + / - 0.1 mm

What Our Customers Say

The testimonials from our clients carry more weight than our own statements. We invite you to read the feedback from our satisfied customers and see how we've successfully met their needs.


This professional shop is run by two of the most reliable people I have met in the industry. Their quality of work, communication, work ethic, and overall performance warrant more than 5 stars. I was even able to sit down with them and work through my design to ensure manufacturability would not be an issue before making an order with them. I know that that was outside of the scope of work for them, but it goes to show how much they care about their clients. 10/10 would recommend.” -

About the CNC Milling Process

With milling, the stock that the part will be cut from is usually a six-sided bar or sheet of material (though it can be also a cylindrical rodi). This stock is fixtured to the bed of the machine and the features of the part are cut using a rotating tool such as a drill or endmill.
