Tx611c/3 CNC Horizontal Boring and Milling Machine Fanuc GSK

1: TX611C series DRO boring mills

The machine tool adopts a single column, horizontal bed, and side-hanging box layout. The X axis is the longitudinal movement of the table along the upper slide, the Y axis is the spindle box moving up and down along the column, and the Z axis is the slide along the bed Lateral movement. 

1. Bed body The large foundations are cast with high-quality gray cast iron and resin sand process. According to the dynamic analysis, reasonable reinforcement is performed to ensure its good resistance to twisting and bending, as well as good accuracy and stability. The Z-axis is a sliding seat that moves laterally along the bed. A rectangular sliding guide is used, which is equipped with a polytetrafluorohexene guide with a very small friction coefficient, which is wear-resistant, pressure-resistant, and stable. Integral steel-paneled auxiliary rail supports on both sides.



2. Worktable Department The worktable consists of a rotary worktable and a slide. The rotary table is supported on two full-circle balls on the upper slide. The worktable adopts a manual rotary structure, which is positioned by pins at four positions of 0 °, 90 °, 180 °, and 270 °. The positioning is accurate and the accuracy is high. The worktable is locked by manual clamping and manually released. A special retractable handle is used for braking, and a ring is rotated by a pair of fan-shaped gear blocks. Four projections are installed on the ring, and the rotary table can be clamped on the slide by rollers and lever groups. Seat. The rotary center shaft is equipped with tapered roller bearings, and the rotary table is supported on the balls, which can easily rotate the rotary table. The T-slot and center hole of the workbench have strict requirements and can be used as a positioning reference. The X axis is the longitudinal movement of the worktable along the upper slide. The guide rail pair uses two rectangular sliding guide rails, which are equipped with a polytetrafluorohexene guide rail with a very small coefficient of friction. After strict scraping and grinding, the abrasion and pressure resistance, Good stability.



3. Column part The large foundations are cast with high-quality gray cast iron and resin sand process. According to the dynamic analysis, reasonable reinforcement is performed to ensure its good resistance to twisting and bending, and at the same time, it has good accuracy and stability. Y axis is the headbox moving up and down along the column, and the column guide rail is self-cooled and hardened. A set of headstock weight balancing device is installed in the column. The weight ratio between the headstock and the counterweight is 1: 1. The headbox moves up and down smoothly and reliably.


4. Spindle box section Different boring shafts and rotation speeds of the rotary disk are changed by AC servo motors, and the gears are moved by the oil cylinder. The hollow spindle is supported on two sets of precision tapered roller bearings, and the inner bore of the hollow spindle is equipped with three bushings. The inner hole of the bushing is precisely processed and has a certain clearance with the boring shaft. The boring shaft can move axially in the hollow main shaft hole and can rotate with the hollow main shaft. The flat rotary disc is supported on two sets of precision tapered roller bearings, and its bearings are supported by the fixed sleeve fastened to the headstock, and the ram on the flat rotary disc can be moved radially for larger processing. Boring of planes and holes. In order to facilitate the tool clamping, the T-slot is also machined in the flat-slide block. A tool clamping mechanism is installed in the boring shaft. The disc spring tightens the chuck through the pull rod to tighten the tool mounted on the boring shaft. When the knife is loosened, the pressure oil pushes the piston in the oil cylinder installed in the tail cylinder to move it forward, so that the pull rod drives the chuck. Move forward together to open the chuck and relax the tool.



5. Operation section The suspension is fastened by the support base on the top of the column. The lower end of the suspension is equipped with a hanging button station. The machine tool is mainly operated through the button station. The suspension can be rotated in the horizontal direction. An electronic handwheel equipped with a spiral cable is hung on the button station, which can be easily removed and held in the hand for operation. The fuel tank is placed under the tail cylinder, flush with the bed, and the power oil is connected to the oil cylinder through a hose to provide the power for the high and low shift of the spindle and the loosening of the spindle. The high and low shift of the main shaft rotation is realized by turning on the solenoid valve on the fuel tank. When the solenoid valve in one direction is turned on, the high-pressure oil pushes the piston rod and the sliding gear is driven by the piston rod. When the tooth top phenomenon occurs, the gear shaft is electrically controlled until the oil cylinder is in place. The file is complete.




6. Lubrication Department The spindle of the machine tool uses a constant temperature oil tank cooling device to ensure the stability and reliability of the spindle for a long time and high speed operation. The main shaft bearings are lubricated with special high-speed bearing grease. The guide rails and screw shafts of each axis are lubricated with Emu Oil, and the centralized lubrication station is used for timing and quantitative lubrication. The electrical control cabinet of the machine tool is dehumidified with dust-proof devices and air conditioners to ensure the long-term stability of the electrical cabinet.


7. Machine tool protection Machine tool rail protection: Special stainless steel rail protection cover is adopted, which not only protects the rail, but also improves the appearance.
