What Is CNC Machining And How It Works
Everything begins with what it is. CNC machining is one of the most commonly used manufacturing methods in modern industries. It uses computer software to control different machining tools (cutting tool, driller, router, etc.) and processes the parts into designed shapes. The key feature of the CNC machining process is automation. It speeds up the production and creates great accuracy.
Nearly all materials we use to make parts can be processed by CNC machining. Consequently, this manufacturing process has been applied in almost every industry related to our daily lives – automotive, construction, aerospace, medical, military, etc. Not to exaggerate, but part of our industry is built on it. Mostly, CNC machines are divided into 5 types based on the tools it uses – CNC milling machine, CNC lathes, CNC laser machine, CNC plasma cutting machine and EDM. The characteristics and structures of a part shall decide which machine to use.
Back to topic, the cost of CNC machining cannot be just determined as high or low. It’s affected by multiple factors. Before we delve into those factors, let’s consider how the cost of CNC looks like compared to other manufacturing processes.
4 Inspection Methods for CNC Machining Parts and Items
1. In the small batch production, the part’s dimensional accuracy is generally inspected with an outside micrometer;
2. In mass production, smooth limit gauges are often used for inspection, and long workpieces with high precision can be inspected with a comparator.
3. The surface roughness of parts can be inspected by roughness template; when the requirements are higher, it can be inspected by optical microscope or profiler.
4. The roundness error of CNC lathe machining part can be determined by the half of the largest difference of the inner diameter, which is in the same section of the workpiece and measured by a micrometer, or can be measured by a dial indicator with the help of a V-shaped iron. If conditions permit, it can be checked with a roundness instrument. The cylindricity error is usually determined by measuring the difference between the maximum and minimum values in the same axial section with a micrometer. The mutual position accuracy inspection of the main shaft generally takes the center hole at both ends of the shaft or the center hole plugged by the process cone as the positioning reference, and the dial gauge is used to measure the top of the two supporting journals.

FAQ
Q: Can I get samples for testing?
A: We can offer free samples, but for big and high-value products, samples will be charged.
Q: Do you accept retail orders? What is the MOQ required?
A: Yes, we accept retail orders. MOQ is negotiable, free to contact us for discussion.
Q:What shall we do if we do not have drawings?
A: Please send your sample to our factory, then we can do the reverse engineering or provideyou better solutions. Please send us pictures or drafts with dimensions (Length, Height, Width), CAD or 3D file will be made for you if placed order.
Q: How much is the freight?
A: We will decide according to your mode of shipping and quantity, it needs you to provide us with a specific mode of transportation(by sea or air), which port or airport to arrive at.
Q: What will you do if we receive poor quality parts?
A: Please kindly send us the pictures, our engineers will find the solutions and remake them for you asap.
