CNC machining is an exciting and dynamic industry that’s constantly evolving. As a mechanical engineer, buyer, or designer, you might have some questions about CNC machining and its applications. In this blog post, we’ll be answering some common questions about CNC machining and introducing you to PROTO MFG, a top CNC machining provider known for high-quality and precision work.

  1. What is CNC machining, and how does it work?
    CNC machining stands for Computer Numerical Control machining. It’s a process where a computer-controlled machine tool extracts material from a workpiece, creating a desired shape or pattern. The computer program sends commands to the machine, telling it how fast to move and how much material to remove. CNC machining is incredibly precise and can produce complex shapes that would be impossible to achieve using conventional machining methods.
  2. How accurate is CNC machining?
    CNC machining is one of the most accurate machining methods available today. The precision is dictated by the tolerances in the CAD model for each part, and the precision of the machine tool. Modern CNC machines can produce parts with tolerances as tight as +/- 0.002″.
  3. What materials can be used for CNC machining?
    CNC machining can be used on a wide variety of materials, including metals like aluminum, brass, steel, and titanium, as well as plastics, composites, and even wood. The material choice depends on the specific requirements of the part, such as strength, weight, and cost.
  4. How does PROTO MFG differentiate itself from other CNC machining providers?
    PROTO MFG is a top-notch CNC machining provider known for its commitment to quality, reliability, and customer service.
