Important Machine Parts
1. Machine Bed
The bed adopts double rectangular flat guide rail structure, and the guide rail width is 500mm. The bed body is the basic component of the machine tool, and its rigidity directly affects the working performance and working accuracy of the whole machine tool.
2. Boring Rod Drive Box
The boring bar box is an integral casting structure and is installed on the feed tray. The choice of rotating speed can be determined according to factors such as workpiece material, hardness, cutting tool and chip breaking condition. According to different speeds, it can be set through the programming of the numerical control system, and the spindle bearings are imported from Japan such as NSK. The main function of the boring bar box is to drive the tool to rotate
3. Oil Feeder & Oil Collector System
The oil receiver is located in the middle of the machine tool. The main functions of the oil receiving part are: 1. Input coolant to the workpiece. 2. The front end of the oiler is equipped with a tool guide sleeve on the top plate of the workpiece, which can realize the guide of the entrance during scraper processing. The oil return device is located at the left end of the machine tool, which can move and be fixed along the axial direction of the bed. The main functions of the oil return device are: The lower part of the oil return body is connected with the T-shaped screw rod in the middle of the bed, and the axial movement realizes the pre-positioning of the workpiece during the processing; it is equipped with a servo motor jacking device (because the jacking adopts the most advanced servo The motor jacking replaces the hydraulic jacking method, so that the adjustment of the jacking force truly realizes digital control. The wall thickness and diameter of the workpiece are different, and different jacking forces are selected to prevent nozzle deformation to the greatest extent.)
4. Machine Feed System
Taiwan Shangyin high-precision ball screw pair is installed in the middle and rear half of the groove of the machine tool body, and there is a feed box at the end, driven by a 5.5KW AC servo motor, to realize the feeding of the tool by the feed pallet (boring bar box). The feed speed can be adjusted steplessly, and the tool can be retracted quickly. The front half of the groove of the machine bed body is equipped with a T-shaped screw and a feed box, which are used for feeding the oil return device, adjusting the workpiece position and clamping. The entire feeding system has the advantages of high precision, good rigidity, smooth movement, and good precision retention.
5. Boring Bar Support System
The supporting sleeve of the boring bar is fixed on the bracket body with screws, and is replaced together with the boring bar, which is convenient and quick to replace different boring bars. It mainly plays the role of supporting the boring bar, controlling the moving direction of the boring bar, and absorbing the vibration of the boring bar. Internal support sleeve with swivel function
6. Workpiece Fixture Support System
Equipped with two sets of V-shaped block brackets to support the workpiece. The screw and nut lifting can be adjusted arbitrarily according to different workpiece diameters. It mainly plays the role of workpiece load-bearing and adjustment, and the position of the boring hole.
7. Hydraulic System
The machine tool is equipped with a special hydraulic system, which is used to control the expansion and contraction of the hydraulic tool and the hydraulic automatic shifting of the boring bar box to complete the control system of the rolling action. The rated pressure is 7Mpa. The main components are imported oil research series products.
8. Coolant Filter System
Cooling chip removal and filtration system: mainly located at the rear of the machine tool, after filtering by chain plate automatic chip removal machine (coarse filter)→first-level oil filter→second-level oil filter and third-level filtration after sedimentation and filtration.
9.Electric System
It consists of main control box, operation box, terminal box and cables. The main electrical components are Schneider brand. For electric control box (air conditioning cooling). The main wiring part adopts aviation plug structure. The cables adopt the national standard, and the weak current cables adopt the shielded cables. The wiring is arranged in strict accordance with the strong and weak electrical isolation.
