CNC Machining: Processes, Materials, and Applications
What is CNC Machining?
CNC (Computer Numeric Control) machining utilizes computer-controlled machines to precisely cut, shape, and finish materials. This subtractive process starts with a solid block of material and removes layers to reveal the final design. CNC machining ensures high accuracy, repeatability, and efficient production, making it ideal for both prototyping and mass production.
Types of CNC Machining
1. CNC Milling
CNC milling involves feeding material into a rotating cutter at different angles. This process is perfect for creating complex shapes and detailed designs. Modern CNC mills use advanced computer controls to achieve exceptional precision and speed.
2. CNC Lathe Machining
CNC lathe machining uses a lathe to rotate the material while a cutting tool shapes it. This process is ideal for producing cylindrical parts, such as shafts and bushings, with precise external grooves and internal holes.
3. CNC Turning
CNC turning uses a lathe to rotate the material while a cutting tool shapes it. This process is ideal for producing cylindrical parts, such as shafts and bushings, with precise external grooves and internal holes.
