JSWAY | Leading CNC Lathe Manufacturer Since 2007
CNC lathe hydraulic power system of variable speed conditions
CNC lathe hydraulic power station behind the part can be used as a module in the machine tool. When need a tailstock's top bulk processing, can be mounted to the hydraulic tailstock top system, make it become the another operational module, sharing the same hydraulic power system. In machining, when the program to the demand for variable speed operation conditions, numerical control system first announced the stop signal, then the program announced the signal starting fuel supply pump, hydraulic system at the same time, electromagnetic valve, according to the control signal and the variable cylinder oil, make the piston rod out or back, forward gear shifting fork, after putting in place when the gear shift, micro switch, CAM and response signal to the numerical control system, the end of the variable speed, program continues to run down to perform machining. Spindle speed change device module on the spindle box, by the stent, oil cylinder and oil tube, micro switch, etc. Bracket width dimension the same as the spindle box at the top of the scale, the spindle speed change device module in the spindle box above the original used to cover plate with four screw holes, and add to play positioning pin hole positioning for the module. Central stents have clapboard, variable speed oil cylinder fixed on the plate, and is located to manipulation of the sliding gear shaft, and guide shaft coaxial; Oil cylinder piston rod is located within the guide shaft, and gear shift fork through the pin shaft coupling; Shifting fork set on the guide shaft, but under the drive of the piston rod move back and forth along the guide shaft; Guide shaft is hollow and open a guide groove, so that the piston rod and the shifting fork, guide shaft by a pin shaft fixed on the bracket; Two gear shift fork are downward vertical structure, respectively in the corresponding sliding gear shifting the slots. With speed oil cylinder oil supply, the piston rod through a pin shaft drives the sliding fork move sliding gear, make the gears meshing gear, gear are obtained by the convex block on the fork of micro switch cover, announced the gear in place signal, for the change over.

Loyalty programs provide an opportunity to learn the preferences of customers and design communication strategies that will resonate with cnc service.
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.
