Important Machine Parts

TGK 10 Deep Hole CNC Skiving & Rollin ( (4)

1. Machine Bed
This deep hole boring machine uses a double rectangular planar rail structure. The bed of this machine tool is made of resin sand and cast with high-quality cast iron HT300. It is a boring machine with good appearance and strength, which makes the machine tool have good wear resistance and precision retention. Make the final product get precise geometric dimensions.

2. Boring Rod Drive Box
The boring bar box is an integral casting structure and is installed on the feed pallet. The spindle is driven by a 45KW AC servo motor, and spindle rotation is driven by the synchronous belt driven by speed change mechanism. The speed range is 3-1000r/min, 4 gears, hydraulic automatic shifting stepless speed regulation. The choice of rotational 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 selected from imported brands such as N SK in Japan. The main function of the boring bar box is to drive the tool to rotate.

3. Oil Feeder System
This boring machine uses oil injection and oil return. Make the machine tool continuously provide cutting fluid to the workpiece during the machining process, thus making the machining process smoother and protecting the workpiece. The oil return device makes the cutting oil form a state of circulating flow in the machine tool, so that the cutting fluid in the processing part will carry waste chips into the recovery box.

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. The iron chips are sent to the chip storage car by the chain plate chip conveyor, the coolant flows back to the oil tank, and then the coolant is supplied to the oil receiver through the cooling pump station, and the oil is supplied by 3 sets of vane pumps to meet the different needs of the workpiece hole size.
When machining the inner hole of the workpiece, the main shaft of the boring bar box drives the tool to rotate, and the iron chips are carried forward by the coolant and discharged through the inner hole of the oil return device. The automatic chip removal machine sends the iron chips to the chip storage car, and the coolant is collected and recovered Reuse.

9. Machine Operation
The machine tool operation control panel is installed on the pressing seat and fixed on the pressing seat carriage, which is convenient for machine tool operation. The panel is made of matt brushed stainless steel, the shape is overall coordinated, beautiful and durable.
The machine software is designed in Siemens and applied for many years. We keep advanced as global level.

10.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.

10.CNC Control System
The machine tool is equipped with SIMENS CNC system with RS232/USB interface, which can be programmed outside the machine. Equipped with a program input and output interface, which can be transferred to the computer. Configure the main control panel and operation button station, Chinese operation interface and operation switches, buttons, etc. Make the machine tool have manual feeding and self-diagnosis functions. Status display, current position display, program display, parameter setting display, alarm display, multi-language display conversion and other functions. Parameter setting is simple, intuitive, convenient and reliable. A PLC tool protection function module is added to effectively avoid the phenomenon of "knife holding".
