Numerical control lathe smooth system alarm problem analysis

in general, smooth handling related to other control system of numerical control lathe is relatively short, but in practice work something shaped like a brief but contains the truth. Analyzes the case of the CNC lathe smooth problem below after summarize and repair can benefit a lot from it. Choose FANUC numerical control system of numerical control lathe, its smooth system, four points by the hydraulic oil tank, oil pump motor oil machine, detection of liquid level and pressure respectively performed by float switches and pressure switches. Smooth after the system pressure reaches the normal operation of 4 MPa, smooth system over 4 smooth circulation, namely by the four road guide rail end points lubrication and progressive, spindle, screw and so on four parts of a smooth, its detection method is by the pressure switch on and off four times, PLC after the action logic signal is detected, the smooth completion, or you think initialization is smooth, and then lead to the police. Progressive type smooth smooth system first by the oil pump, progressive assignments distributor and cohesion to the distributor, the distributor to the oil pump of all kinds of pipe parts. Its structure is made up of smooth pump out smooth oil/grease through progressive homework distributor with progressive methods supply the smooth parts. Progressive type oil distributor is a smooth oil metering, and homework assignments according to sequence must be smooth components together. Can will quantitative smooth oil ( Fat) According to the rules of the order from the oil outlet progressive outlet and to smooth points one by one, can not only apply to the end pressure oil in 1 ~ 6 MPa smooth smooth, and can apply to the end pressure in 1 ~ 5 MPa smooth fat is smooth. Structurally divided into two types: the type, type, on the basis of practice can choose different structure and different combinations, can complete cycle or approximate continuous and smooth. Nc lathe system smooth movement theory: progressive type concentrated smooth system in constitute the system of progressive operations on action method has a characteristic of distributor, distributor progressive assignment is distributor within the plunger in the smooth pumping agent under the pressure of the progressive movement, distributing the smooth agent for oil parts. During the smooth agent sent to the distributor by pump pressure, piston action repeatedly, give oil smooth agent distributed to each site, along with the oil pump and a moment of the number of supply and oil to oil parts, smooth start-stop moment control of pump are set in the machine PLC programming. Just enter the progressive to maintain smooth operation of distributor agent must stress, distributor can continuous operation. Just any one in the center piece of live his death cannot move, other center piece of the piston will all be blocked, the distributor will cease to work, just in the center piece of setting induction piston movement near the switch, can alarm in time when piston is blocked.

JSWAY can also foster research that is more useful and influential in society at large.
