4, the transformation of the lubrication part of the old-fashioned traditional lathes in addition to the spindle box, rails, screw pairs, polished rods and other oil guns with regular oil lubrication and grease lubrication, which is very unfavorable for the accuracy of the guide rails, screw rods, etc. The stability and flexibility of the machine movement under driving are also poor.
Figure 3 Lubrication of the machine tool
In the modification of these machine tools, the lubrication part should be modified accordingly. The method of concentrated oil concentration and timed oil lubrication can be divided into manual lubrication and automatic lubrication. After the screw pair is arranged, the oil circuit can be selected as needed.
Screw-supported bearings are generally lubricated with grease, and can be lubricated with thin oil if special needs and oil supply are sufficient.
5. After the transformation of the machine tool protection machine, the whole protection is divided into three types: partial protection, semi-protection and full protection.
Local protection only takes protective measures against the screw pair, motor, and wiring. Semi-protection is to increase the protection of cutting on the basis of local protection, that is, to increase the chip removal device. The full protection means that the whole machine tool is closed on the basis of local protection. This kind of protection is the most difficult to handle, and many factors are considered, such as installation position, waterproof, and beautiful appearance. In practice, the two are the most common and the easiest to operate.
Fourth, the CNC transformation parameters FBI <br> <br> machine installation, the system required after setting, when the FBI needed to complete a variety of mechanical and electrical operation test, test function, running empty, load test, test Whether the machine meets the requirements after the numerical control transformation.
1. Check before the air run The appearance check of the machine before power-on (check the assembly quality of each part of the machine so that they can work normally after power-on).
(1) The important fixed joint surface should be tightly fitted. It should not be inserted when it is inspected with a 0.03 feeler gauge. The end of the sliding guide surface should be inspected with a depth of less than 20 mm with a 0.03 feeler gauge. The important fixed joint surface is the joint surface of the headboard and the bed, the joint surface of the turret base and the slide, the joint surface of the tailstock and the tailstock floor, and the combination of the bed and the bed (stitched bed) Surface, the joint surface of the steel guide rail and the base member.
(2) Carefully check whether each box and each moving part is refueling as required. The oil level in the box shall not be lower than the oil marking line. Is there enough coolant in the cooling box, whether the oil in the hydraulic station or automatic intermittent lubrication device reaches the oil level specified by the oil level indicator, whether the switches and components in the electrical control box are normal, and whether the integrated circuit boards are inserted In place, the centralized lubrication device is activated to energize the lubrication parts and the lubricating oil line.
2, various action tests (1) manual operation test, such as the lathe relies on manual movement of the tool holder along the positive and negative directions of X, Z and one-way feed movement. Mainly to test the accuracy of manual operation, this function is mostly used when machining the tool.
(2) Jog test In the jog state, the tool holder is moved slowly and then moved quickly, and the magnification conversion is performed.
(3) Spindle shift test The spindle shift test can be carried out according to the shift command specified in the manual.
