Understanding CNC Machines
Types of CNC machines
We use a variety of CNC machines in our Shengen factory, each with a specific purpose. CNC mills cut and shape metal and other solid materials. Similarly, lathes cut cylinders by rotating the workpiece against a cutting tool. We also have plasma cutters and routers to cut metals with precision.
Components of CNC Machine
A CNC machine comprises several vital components. The controller is at the heart of a CNC machine. It interprets design files and commands them. A spindle is also part of the machine, and it spins and holds the cutting tool. Operators place the workpiece on the bed and move the tool along different axes to shape the material. The design of each part ensures seamless operation and optimal performance.
What is CNC Machines? A Technical Overview
Our engineers create a digital drawing. First, the design is translated into a CNC computer program. The program is executed after setting up the machine and selecting the tools and materials. The cutting tool follows a set path, removing the material to create the desired shape. Precision and accuracy are paramount; we ensure each part meets strict quality standards.
Materials used in CNC Machining
Commonly used materials
Shengen works with a variety of materials that are suitable for different industries. Metals such as aluminum, steel, and brass are famous for their versatility and strength. Materials such as ABS, polycarbonate, and PEEK are often chosen for their lightweight and corrosion resistance. Our expertise allows us to choose the best material for every project.
The Right Material for the Job: Durability, Strength, and Cost
The choice of the suitable material is crucial. Strength and durability are important factors, particularly for parts subjected to extreme conditions or stress. The cost-effectiveness of the product is another crucial factor. Our team balances all these factors to offer the best value to our clients. Aluminum is favored for its excellent weight-to-strength ratio. Plastics are chosen for applications that require less strength because of their cost-effectiveness.
Material Challenges and Limitations
Each material has its limits. Due to their hardness, metals can be difficult to machine, which affects tool wear and production times. Plastics are easier to work with but may need more strength for specific applications. We also consider factors such as heat resistance, chemical exposure, and environmental impact. We can navigate these challenges with ease, thanks to our extensive experience.
CNC Machining Processes
