What is Double Column Ram-Type CNC Milling Machine?

A double column ram-type CNC milling machine, also known as a double column machining center, is a type of milling machine that incorporates a double column structure for increased rigidity and stability during machining operations. It is a highly versatile and powerful machine used for precision milling, drilling, and cutting of large and heavy workpieces.

Here are the key features and characteristics of a double column ram-type CNC milling machine:

  1. Double Column Structure: The machine’s construction consists of two large, parallel columns on either side of the work area. These columns provide enhanced stability and support to the machine’s crossbeam and spindle assembly, ensuring minimal deflection during heavy cutting operations.
  2. Ram-Type Design: The machine features a movable ram or crossbeam that spans between the two columns. The ram can move vertically along the columns and is equipped with a milling head or spindle assembly.
  3. CNC Control: The machine is equipped with a computer numerical control (CNC) system that allows for precise control of the machine’s movements and machining operations. CNC programming enables automation, repeatability, and complex machining capabilities.
  4. Large Work Area: Double column ram-type machines are designed to handle large workpieces, both in terms of size and weight. The wide spacing between the columns allows for the machining of oversized parts with high accuracy.
  5. High Precision and Rigidity: The double column structure provides excellent rigidity and stability, ensuring minimal vibration and deflection during cutting. This results in enhanced machining precision and surface finish.
  6. Versatile Machining Capabilities: The machine can perform a wide range of machining operations, including milling, drilling, tapping, boring, and contouring. It can accommodate various cutting tools and attachments to meet different machining requirements.
  7. Heavy-Duty Cutting: With its robust structure and powerful spindle, a double column ram-type machine is capable of handling heavy-duty cutting operations on tough materials such as steel, aluminum, and cast iron.
  8. Automation and Efficiency: These machines can often be equipped with automatic tool changers, pallet changers, and other automation features, enabling continuous operation and increased productivity.

Double column ram-type CNC milling machines are commonly used in industries such as aerospace, automotive, mold and die, energy, and heavy machinery manufacturing. They are preferred for machining large components that demand high precision, structural integrity, and productivity.
