CNC machining is one of the most common machining methods. Prototype, small batch production all rely on CNC machining precision, size, cost and other advantages. Understanding CNC plastic processing helps you to further understand whether your project needs CNC plastic processing, and what plastic processing is required. In order to better compare plastic prototypes and small batch plastic parts, we also compared the strongest alternative to CNC plastic processing - 3D printing. Help you get started with CNC plastic processing.
CNC plastic processing technology
CNC machining is a subtractive manufacturing process. CNC plastic machining uses a subtraction process to gradually cut plastic blocks to the desired shape and precision. Depending on the plastic material, design complexity and precision requirements, a 3, 4, 5-axis CNC machine is usually used to process the part. The more axes the machining process allows the more moving tools and cutting surfaces to run, the faster and more accurate the parts will be processed.
Three-axis CNC machines: Produce the most common parts that do not require multiple rotations, usually for drilling, milling grooves, or machining prefabricated edges.
Four-axis CNC machine: allows the tool to enter the other side of the part for cutting, grooving and other cuts.
Five-axis CNC machines: Capable of producing parts with the highest precision and providing multi-sided rotation to access all sides of the part. Through 360-degree cutting, complex details and fine precision can be achieved. Five-axis cutting is widely used in aerospace, medical, automotive and industrial industries.
