1, Bed body
The bed is the basic structure of a vertical milling machine, which bears the weight of the entire machine tool and various forces during the machining process. The bed body is usually made of high-strength cast iron or steel, which has sufficient rigidity and stability to ensure accuracy and stability during the processing. The bed is also equipped with guide rails to support and guide the workbench and other moving parts.
2, Spindle box
The spindle box is one of the core components of a vertical milling machine, mainly used for installing and driving milling cutters for cutting processing. The spindle box is equipped with a spindle motor and a transmission mechanism inside, which drives the spindle to rotate and transmits power to the milling cutter through the transmission mechanism. The spindle box is also equipped with a lubrication and cooling system to ensure the normal operation and heat dissipation of the spindle and transmission mechanism.
3, Workbench
A worktable is a platform used for clamping workpieces on a vertical milling machine, which achieves relative motion between the workpiece and the milling cutter through the movement of the worktable. Workbenches are usually composed of structures such as T-slots or circular holes, which facilitate the positioning and clamping of workpieces. There are guide rails and feed mechanisms installed below the workbench, which achieve precise feed of the workbench through servo motors or hydraulic cylinders and other driving devices.
4, Feed mechanism
The feed mechanism is a device for vertical milling machines to achieve workpiece feed motion, including a transverse feed mechanism and a longitudinal feed mechanism. The feed mechanism is usually composed of servo motors, ball screws, linear guides, and other components. The motion of the servo motor is controlled by a CNC system to drive the rotation of the ball screw, thereby driving the workbench to achieve precise feed motion on the linear guide.
5, Lift table
The lifting table is a device on a vertical milling machine used to adjust the distance between the milling cutter and the workpiece. The lifting platform usually achieves lifting motion through manual or electric means to adapt to the processing needs of workpieces at different heights. The lifting accuracy and stability of the lifting platform have a significant impact on the machining accuracy.
6, Lubrication system
The lubrication system is one of the indispensable auxiliary systems in vertical milling machines, mainly used for lubrication and maintenance of various moving parts of the machine tool. The lubrication system delivers lubricating oil to various parts that require lubrication, such as guide rails, bearings, etc., through an oil pump to reduce friction and wear, improve the service life and machining accuracy of the machine tool.
7, Cooling system
The cooling system is mainly used to reduce the heat generated by the vertical milling machine during the machining process, in order to ensure the normal operation and machining accuracy of the machine tool. The cooling system usually includes components such as a coolant tank, coolant pump, and coolant pipeline. The coolant is transported to the cutting area through the coolant pump, taking away the heat generated during the cutting process, reducing the cutting temperature, and improving the service life and machining quality of the tool.
In addition to the seven main components mentioned above, vertical milling machines may also be equipped with other auxiliary devices, such as chip removal devices, protective covers, etc., to improve processing efficiency and safety.
