Numerical control lathe smooth system fault analysis of alarm
in general, smooth handling related to other control system of numerical control lathe is relatively simple, but in the practical operation seems simple but contains the truth. Analyzes the case of the CNC lathe smooth problem below through summarizing, repairs and 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 by the float switch and pressure switch is gone. 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 completion of smooth, smooth or you think the initialization failed, and then lead to the police. Progressive type smooth smooth system first by the oil pump, progressive distributor, and connect the pump to the distributor, the distributor to give oil of all kinds of pipe parts. Its structure is made up of smooth pump out smooth oil/grease by progressive homework distributor to the smooth parts scattered supply in progressive way. Progressive type oil distributor is a smooth oil metering, and according to the order must be running operations smooth components. 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. Divided into two major categories of monolithic, chip from the structure, according to the different structure of practice can be selected and different combinations, can end cycle or approximate string is 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 smooth agent sent to the distributor by pump pressure, plunger repetitive movements, give oil smooth agent distributed to each site, along with the oil pump oil and a time to give parts and oil supply times different, smooth start-stop moment control of pump are set in the machine PLC programming. Just enter the progressive smooth agent insist on homework distributor must stress, distributor will be able to have homework. 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 set in the center piece of inductive proximity switch of piston movement, can alarm in time when piston is blocked.

I. Functional role
Slideways are the “track” between the guide rail and the moving parts. They convert the rotary (or linear) thrust of the servo motor into precise linear motion of the machine table, spindle box or turret, while withstanding cutting reaction forces, shocks and vibrations. Once the slideway fails, the positioning accuracy and surface quality of the whole machine will drop directly.
II. Common structure family
Linear ball slideway
Steel balls are in point contact with the raceway, low friction and fast response, suitable for high-speed and light-load Swiss-type lathes or vertical machining centers.
Linear roller slideway
Cylindrical rollers are in line contact with the raceway, high rigidity and large load capacity, the first choice for heavy-cutting equipment such as turn-mill centers and gantry five-face machines.
Dovetail slideway
Triangular interlocking surface, extremely strong lateral force resistance, often used in grinders or ultra-precision machining units that require micro-feed.
Hydrostatic/hydraulic slideway
Oil film supports moving parts, almost zero wear, used for mirror grinding or heavy-duty boring machines, but demanding on the oil supply system.
On September 3, 2025, China solemnly commemorated the victory in the War of Resistance Against Japanese Aggression and the World Anti-Fascist War. Behind the pageantry that displayed national strength and a commitment to peace, countless Chinese manufacturers are injecting their craftsmanship and cooperative spirit into the global economy. JSWAY CNC COMPANY is one of them, answering the call for peace and development in its own way.
For two decades JSWAY has focused on high-configuration, high-precision, high-speed CNC lathes and Swiss-type lathes. Products now reach more than thirty countries and regions, illustrating the principle of “peace through development, excellence through quality.”
True high-end manufacturing is not only technological breakthrough but also stability of quality. JSWAY’s plant houses about forty thousand square metres of floor space, producing Swiss-type lathes, turn-mill centres, gang-tool lathes and turret lathes. Critical components are machined on horizontal machining centres, gantry-type five-face machining centres and precision grinders, ensuring consistent accuracy.
An engineering data centre and joint laboratory use laser interferometers, eddy-current displacement testers, wireless rotary axis calibrators, high-precision digital temperature sensors and real-time machine-error compensation systems to upgrade products continuously.
