Frequently Asked Questions (FAQs)

Frequently Asked Questions About CNC for Metal Factories in China

What is CNC Machining and how does it work?

CNC machining is a process that uses computers to control machine tools like lathes, mills, and grinders. This technology allows for precise and automated movements, enabling the creation of intricate parts with high accuracy. Essentially, computer-driven electric signals control motors that make tiny, incremental movements, ensuring the exact precision needed for modern technology.

What are the advantages of CNC machining over manual machining?

CNC machining offers several advantages over manual machining. It provides automated precision and repetitive capabilities that manual machining can’t match. CNC machines can handle complex designs and last-minute changes efficiently, reducing production time and costs. They also ensure consistent quality and higher productivity, making them ideal for multiple applications in a short period.

How precise can CNC machining be?

CNC machining can achieve very high precision. The highest precision can be up to 0.005mm, depending on the machine and the process. This level of precision is crucial for producing parts that meet strict tolerance requirements, making CNC machining ideal for industries that demand high accuracy.

What materials can be used in CNC machining?

CNC machining is versatile and can work with a wide range of materials, including metals like aluminum, stainless steel, titanium, and copper, as well as plastics and composites. This flexibility allows you to choose the best material for your specific application, whether it’s for strength, durability, or other properties.

How long does it take to produce parts using CNC machining?

The production time for CNC machining varies based on the complexity of the parts, the quantity ordered, and whether any tooling is required. Generally, for standard specifications, you can expect delivery times ranging from 7-15 days for simple parts to 60 days for high-end or custom models. Mass production typically takes around 15-25 days after receiving the deposit.
