1. Structural composition:

The bed adopts a welded structure and is annealed after welding. Ensuring sufficient rigidity and accuracy stability. Its characteristics are: the bed body is improved by adopting a floor boring and milling machine style. There are two heavy-duty linear rolling guide pairs and precision screw pairs with ultra-high load-bearing capacity installed on the bed, which are used to drive the horizontal movement of the slide tableAC servo motor drive ensures high positioning accuracy and repeatability of the machine tool. There are adjustable bolts distributed on the bottom surface of the bed, which can easily adjust the level of the bed.

The milling head adopts1TX32The characteristics of the milling head include high overall rigidity, reliable performance, wide speed range, good rigidity, low noise, high efficiency, and easy operation. The spindle speed is125-630rpm， Install the cutterhead with a diameter of φ125-200mm。

The sliding table system is made of welded steel structure, which is subjected to artificial aging heat treatment and stress relief annealing treatment to eliminate stress. Both dynamic and static rigidity are excellent. Its guide rail adopts heavy-duty linear rolling guide rail and has good lubrication conditions. The movement of the slide table is achieved by a servo motor driving a precision screw to rotate through a reducer to achieve feed motion. Servo drive can achieve fast forward, work in, and rewind movements of the slide table, as well as precise positioning function of the slide table. There are columns installed on the slide table, which drive it to complete reciprocating cutting motion.

The column adopts a welded structure and undergoes annealing treatment after welding. Ensuring sufficient rigidity and accuracy stability. Its characteristics are: the column is improved by imitating the style of a floor boring and milling machine. The guide rail adopts heavy-duty linear rolling guide rail. This type of mechanism ensures the implementation ofWhen milling at a height of 1.2m, the machine tool has no vibration phenomenon, ensuring the accuracy and efficiency of milling.

Vertical counterweight mechanism, a mechanical counterweight mechanism is installed on the vertical lifting mechanism of the milling unit, mainly used to balance the self weight of the milling unit, use the milling unit to move smoothly in the vertical direction, and ensure the service life of the vertical screw.

The hydraulic workpiece clamping fixture consists of two independent clamping mechanisms. It can automatically clamp the workpiece horizontally and vertically to ensure its stability during processing. The horizontal and vertical clamping mechanisms can be adjusted to meet the clamping needs of workpieces of different sizes. The clamping method is hydraulic automatic clamping. (Vertically clamp one set, horizontally clamp two sets)

2. Feed structure:

The feed of the bed slide table adopts a screw nut pair transmission, and the horizontal column is achieved through servo drive（Move along the X-axis.

The vertical feed of the milling unit adopts a screw nut pair transmission, and the milling unit is driven vertically by servo drive（Y-axis movement.

3. Protective mechanism:

The bed guide rail protective device adopts a flexible and rigid steel dust-proof cover with good load-bearing capacity. The column guide rail protection device adopts a telescopic nested nylon dustproof protective cover, which has good sealing, good heat dissipation, and long service life. There are peepholes on the fixed protective cover to observe the lubrication and cleanliness of the guide rail, and to add oil to the bed and body guide rail; The peephole is equipped with a cover plate, which should be closed after use.

4. Lubrication mechanism:

The machine tool lubrication adopts centralized automatic lubrication,Equipped with an automatic lubrication device, it can automatically lubricate various moving pairs such as guide rails and lead screws.
