Milling is a popular CNC machining operation that uses rotary cutters to remove material from a workpiece. This operation is ideal for producing complex and 3D parts with high precision. Milling machines can perform different types of milling operations, including face milling, end milling, and slot milling. Milling can be performed on a wide range of materials, including metals, plastics, and composites.
CNC Turning Machining
Turning is another common CNC machining operation that rotates a workpiece while a cutting tool removes material. This operation is ideal for producing cylindrical parts with high precision, such as shafts, bolts, and nuts. Turning machines can perform different types of turning operations, including facing, taper turning, and thread cutting. Turning can be performed on a wide range of materials, including metals, plastics, and woods.
CNC Drilling Machining
Drilling is a CNC machining operation that creates holes in a workpiece using a rotating drill bit. This operation is ideal for producing holes with precise depths, diameters, and spacing. Drilling machines can perform different types of drilling operations, including center drilling, counterboring, and countersinking. Drilling can be performed on a wide range of materials, including metals, plastics, and ceramics.
CNC Laser Cutting Machining
Laser cutting is a CNC machining operation that uses a high-powered laser beam to cut a workpiece into a specific shape. This operation is ideal for producing parts with intricate shapes and designs. Laser cutting machines can perform different types of laser cutting operations, including vector cutting, raster engraving, and 3D laser cutting. Laser cutting can be performed on a wide range of materials, including metals, plastics, and woods.
