About cnc milling machine moving column

Types of CNC Milling Machines Moving Column

The CNC milling machine works in a way that cuts materials with the use of a controller that is computer-based. It is a process commonly used to create and shape parts from materials like aluminum, metal, plastic, wood, etc. This technique is usually used to lay out and/or make pieces for complex builds and projects.

CNC milling machines have different types that can be used for any project with ease. Here are some common types:

  • CNC moving column milling machine: This machine has a column that can be moved in order to facilitate the cutting process of the target object. The column of the machine usually moves in a vertical direction while it has other features that can be used to cut objects in different directions.
  • CNC gantry milling machine: This device has its cutting tool and spindle mounted on a two-legged frame (known as the gantry) that moves along a horizontal beam. It is primarily used for processing large and heavy workpieces. It is usually suitable for high-speed cutting and engravings.
  • CNC vertical milling machine: Unlike the horizontal one that has a horizontal spindle, this device has a vertically oriented spindle that is used to cut objects. The tool used in this device goes downward vertically, thus making it easier to see and cut more detailed areas precisely.
  • CNC horizontal milling machine: In this device, the spindle is oriented in a horizontal direction, allowing the cutting of work materials with the help of an array of circular saws and a horizontal cutting action. It is usually used for high-precision machining of complex parts.
  • CNC Turret Milling Machine: The turret milling machine refers to the procedure in which the spindle can move vertically and horizontally, allowing the device to accomplish a wide range of tasks by just changing the direction of the tool.

Specification and maintenance of a CNC milling machine moving column

CNC moving column milling machine's specifications vary depending on the model. Key specifications include the machine's size, axle's load capacity, work table's bearing capacity, maximum feed rate, and power.

  • Machine's size: The overall dimensions (length, width, and height) of the machine are usually expressed in mm. A standard moving column CNC machine's size is about 3920*1700*2100 mm. Generally, the overall dimension is large owing to the moving column design, which makes it ideal for machining big workpieces.
  • Axle load capacity: The moving column CNC machine's axle configuration and load capacity differ. For instance, some moving column machines have a Y-axis length of 2200 mm, an X-axis of 3200 mm, and a Z-axis of 1200 mm. Moreover, the moving column CNC machine's foundation and support structure influence the axle's load-bearing capacity. So, some CNC moving column machines can support a moving load of 8000 kg, while others can only support 6000 kg.
  • Power: A CNC milling machine's spindle motor has different powers. The moving column machine generally has a spindle motor with a power of 15 KW. A motor with higher power can achieve more efficient machining and greater torque.
  • Maximum feed rate: The maximum feed rate of a moving column CNC machine is indicated in m/min. Generally, it can achieve a maximum feed rate of 18 m/min to 25 m/min. The feed mechanism, control system, motor, and axle assembly of the machine affect its feeding speed.

Milling machines with a moving column design typically require less maintenance than other machines because the machine's part do not wear out quickly due to frequent movement. Nevertheless, manufacturers and moving column machine operators still perform some routine maintenance procedures.

  • Regular inspection: Regular inspection of the column CNC machine helps the technician identify any abnormal parts, signs of wear, and faults so they can fix them immediately. This reduces the risk of a breakdown.
  • Lubrication: During maintenance, the moving column CNC is usually lubricated to reduce friction and wear. Lubricate sliding parts, bearings, racks, and rollers with high-precision lubricant oil.
  • Dust cleaning: Dust and debris accumulate on the moving column CNC machine after some time. Therefore, during routine maintenance, wipe the machine's surface with a clean, soft cloth. Getting rid of dust and debris helps improve engraving precision and protects internal parts of the machine such as the electric components and motor.

  • Machine types:

    The direction of one's application and project needs can be further streamlined by considering the various types of CNC milling machines with a moving column. Pay attention to the configuration and structure of each machine type, as this will impact its suitability for various projects and applications.

  • Controller system:

    It's crucial to ensure that the CNC controller in question has a user-friendly interface. Operators should be able to easily program, monitor, and manage the CNC milling process without experiencing significant downtime. Furthermore, it is also necessary to check if the CNC controller supports remote monitoring and diagnostics capabilities. The ability to remotely monitor the machine's performance and receive diagnostic information is extremely valuable. This feature enables operators to monitor the CNC milling process in real-time, allowing for proactive maintenance and timely response to any issues that may arise. It ultimately helps optimize machine utilization and minimize unplanned interruptions in the production workflow.

  • Integration and automation:
