WHAT ARE THE MAIN CNC MILLING MACHINE PARTS AND COMPONENTS?
The main parts of CNC milling machine include shaft, worktable, spindle, frame, NC controller and other accessories, while accessories include coolant, lubrication system, power tie rod, housing and fourth axis. Next we will introduce it in detail.
The rack is located on the ground or foundation of the CNC milling machine. It acts both a support and a damper for machine vibration. The frame material may be granite-filled welded structure. Almost no steel is generally used as a milling frame, because it has some spring properties and very little damping capacity. There is another innovative idea, which is to use epoxy resin with different sizes of stone in welded steel containers. The epoxy granite mixture is a good damper, and the strength increases when it is confined to steel vessels. Install foundation bolts on the frame so that they are rigidly connected to the ground.
The CNC milling machine is connected to the frame to provide movement in each direction. Since the machine is controlled by a computer, it is programmed. It can also be done manually. A normal CNC is called a 3-axis CNC. And can move in three directions. The components which are connected to the CNC shaft include motors, various modes, worktables, limit switches and lead screws. Typically, shafts move in the XY and Z directions, but sometimes an optional 4th axis is required, and it is kept in the attachment list. Five axis milling is also visible, but not very common. The motor can offer motion for the table in a way that provides smooth sliding motion. Swallowtail and straight line are often used in shaft assembly. The lead screw provides linear motion when extracting the rotating motion of the motor.
