CNC machining uses cutting tools to eliminate superfluous raw material from workpieces in order to generate a precise final product out of materials like plastic, metal, and composites. Multi-axis machining options now include 3-axis, 5-axis, and even 9-axis machining, giving product teams a wide range of choices. What distinguishes one category from the others? In this post, we’ll compare and contrast the two common forms of CNC machining, highlight their important similarities and differences, and explain when it would be more advantageous to utilize one over the other.
A tool used in 5-axis machines can travel in five directions: X, Y, Z, as well as A and B, around which it rotates. The need to ᴍᴀɴually move the workpiece between operations is eliminated when using a 5 axis CNC machine, which enables operators to approach from all directions in a single operation. The ideal ᴍᴇᴛʜod for producing complex and accurate parts for the aerospace, oil & gas, and medical industries is time-efficient 5-axis CNC machining. A few various kinds of 5-axis machines, such as mill-turning CNC centers, continuous 5-axis CNC machines, and indexed 5-axis CNC machines, need to be understood by product teams.
Similar to 3-axis CNC milling, indexed 5-axis CNC machining only moves the cutting tool along three axes and does not maintain consistent contact with the workpiece. The cutting table and tool head, however, can automatically swivel in two directions in between operations. With the aid of indexed 5-axis machining, housings, jigs, and fixtures may be easily created. It falls between continuous 5-axis CNC machining and 3-axis CNC milling in terms of speed, precision, and ability to handle complex geometries. Continuous 5-axis CNC machining speeds up production and enables the construction of complicated geometries with organic surfaces by allowing simultaneous rotation and movement of the workpiece and cutting tool. Although continuous 5-axis CNC machining has the highest cost per product, it enhances dimensional stability, speed, and surface polish.
Turning lathe With the exception of having CNC milling machinery, CNC centers are nearly ɪᴅᴇɴᴛɪᴄᴀʟ to CNC turning machines. Cutting tools attach to a spindle that can revolve or remain stationary and remove material from the workpiece as it is being worked. Integrating CNC lathe and milling equipment enables mill-turning. Due to their high levels of accuracy and geometric versatility, CNC centers are suitable for making parts with asymmetric rotational symmetries, such as camshafts or centrifugal compressors.
These 5-axis CNC milling machines not only offer larger yields and faster machining speeds, but also greater precision when cutting deeper pieces and hardened materials. Due to the sophisticated equipment required and the deᴍᴀɴd for sᴋɪʟʟed labor, 5 axis machining is more expensive.
