CNC machining is a versatile process that can handle different materials, making it suitable for various industries and applications. The most commonly used materials for CNC machining are metals such as brass, stainless steel, copper, titanium, and aluminum because of their durability, strength, and resistance to corrosion.

Plastics like polycarbonate, nylon, and ABS are also frequently used for CNC machining because they are lightweight, long-lasting, and can be molded into different shapes and sizes. Furthermore, some types of ceramics can be employed in CNC machining since they have excellent thermal and electrical insulation characteristics.

Our CNC Machining Process Steps

Analyze the CAD&3D drawings of the processed parts, determine the relevant processing data (coordinate points of the tool path, machining cutting amount, tool size information, etc.), and determine other relevant auxiliary information and related equipment process information, fixture selection, tool type selection, etc. according to the process plan.

Convert CAD model to CNC program: Once the CAD model is ready, convert it to a CNC program. The program contains all the instructions needed to create the part, including cutting paths, tool selection and cutting speed.

Engineers install the necessary cutting tools and fixtures and program the machines to follow CNC programs.

When the program is executed, the CNC system of the machine tool will decode, host and calculate the program, send motion instructions to the machine tool servo mechanism, drive the machine tool moving parts, and automatically complete the processing of the workpiece.

Once a part is machined, it undergoes a quality control inspection to ensure it meets specified tolerances and dimensions. Different spot sizes will be measured according to the customer's design files and tolerance requirements.

Depending on the application and customer's needs, parts may undergo additional finishing processes such as polishing, coating, anodizing, laser engraving, and more.

After finishing the surface treatment, we will do a final inspection and packing before shipment. Our professional workers will make sure the quality is 100% qualified before shipping.

FAQs

1. What is the minimum order quantity for CNC machining customization?

In principle, our MOQ is one piece, but considering that the price of a single piece sample is usually higher, we suggest customers to choose a small quantity order of more than 10 pieces.

2. I asked several factories, why the price is high or low?

Each processing factory has its own way of operation, any irresponsible quotation is a one-time sale, we only emphasize on making the best products, and receive every customer with the fastest speed and the most enthusiastic service.

3. What should I do if the product does not meet the quality requirements?

First of all, let's analyze where the problem lies. If it is our processing error, we will arrange redo or full refund as soon as possible. If the product is scrapped due to an error in the customer's drawing, we will negotiate separately. Please rest assured that any problems can be resolved through communication and negotiation. , until you are satisfied.
