How we process your CNC machining parts order?

01

Preparing for project

Our preparation work often starts from your purchase order, firstly we will review the purchase order detailed request. Drawing revision is the most important in verifying the process, ensuring the material, dimension tolerances and surface treatment and other technical specifications are the latest before moving to further steps.

02

Preparation from our engineer and programmer team

Our Engineers will make a flow machining card, and our programmer use 3D software in order to produce a computer model of customer drawings and design. This can help to reveal any potential issues that weren’t evident from the product design itself. We could fastly communicate with our customers and deal with any problems maybe exist.

03

Pre-Machining Preparations

For a successful custom CNC machining, the critical things necessary to be prepared are the raw materials, Incoming inspection, CNC program, cutting tools, part holding fixtures, and measuring tools. These preliminary procedures will ensure a smooth machining process.

04

Production

From a fundamental standpoint, the three primary operations in machining are turning, drilling, and milling. Secondary operations can be added to achieve the required shape, precision, mechanical properties, or surface finish. We will machine step by step according to the process flow chat, which could ensure the machining process in the correct way.

05

Surface finishing

The surface finishing process is the final step in CNC machining., the surface treatment is a possible way to obtain sufficient resistance against environmental attack oxidation. It could meet your request for smooth finishes or additional corrosion and wear resistance.

06

Quality Inspection

Quality control makes great sense for accuracy and precision. The common metrics checked in machined parts are usually dimensional accuracy, surface finish, and structural integrity.

07

Protection before shipment

Packing products as well comply with the packaging standard to avoid the goods being damaged during transportation.

08

Ready for shipping

You could choose your safe and convenient delivery ways by (express DHL, UPS Fedex, OCS) or sea transportation

You may ask us anything about CNC machining

Parts can be turned and milled from ferrous or non-ferrous materials to suit customer requirements. The customer’s choice of material depends on the characteristics of the end product, the machining operations required, and the technical suitability of the material for the part to be produced.

We use the following raw materials to produce parts. Please contact us if the material needed for your part is not listed.

Aluminum Alloy, Copper Alloy, Carbon Steel, Stainless Steel, Tool steel, Titanium, and Engineering Plastics.

We can accept most of the 3D file formats like SolidWorks IGES(.igs) / STEP (.stp). We can also use 2D drawing (.pdf) or AutoCAD (.dwg) for quotes against the parts with simple structures. All the other file formats are not listed above but can be read in AutoCAD/SolidWorks/which will be also fine for us.
We can generally quote you back within 24 hours in most cases. Depending on the complexity of the project, we ensure to send you a competitive quote no exceed 48 hours.
Only the uncompleted parts and available changes can be accepted during the productions.
Our standard shipping term is Ex Works (EXW). The customer is responsible for shipping costs and imported tax.

More money it’s going to cost more if there are greater set-up needs, lengthier cycle times, and additional fixturing or specialized tools.

There are times when a tight fit tolerance is mandatory. However, when carefully considering end-use you can determine between critical and non-critical tolerances, avoid unnecessary tight tolerances, and reduce your cost of quality.
