JSWAY | Leading CNC Lathe Manufacturer Since 2007
Numerical control lathe guide rail which basic requirements demand satisfaction?
CNC lathe guide according to the motion track can be divided into linear motion guide rail and circular motion guide rail; According to the job nature mainly can be divided into motion guide rail, feed motion guide rail and a guide rail; According to the contact area of the nature of the conflict can be divided into sliding guide rail and the rolling guideway. CNC lathe guide in nc machining of 'play' a very important role, so what are the basic requirements for the following? 1. Higher precision guidance accuracy refers to the movement of the lathe parts moves along the rail lines and between it and the base of mutual bearing accuracy. No matter when no load or cutting the workpiece, guide should have satisfactory guidance precision, this is a basic requirement of guide rail. Primary reason affected the accuracy of guide rail, besides making precision and guide way structure, installation quality, guide rail and the rigidity and thermal deformation of bearing, on hydrostatic guideway and oil film stiffness, etc. 2. Wear-resisting performance is better guide rail wear is in the process of long-term use guide rail insist must guide the ability of precision. Numerical control lathe for guide not wear in the operation process, so, should strive to reduce wear and can active compensation or facilitate adjustment after the wear and tear. Numerical control lathe often choose conflict coefficient of rolling guideway and hydrostatic guideway, to decrease guide rail wear. 3. Be satisfied with the stiffness of rail stress deformation will affect the components between the guidance precision and relative orientation, therefore, demand guide should have satisfactory degree. To reduce or balance the effect of external force, often for the CNC lathe more guide the dimensions or lick for guide stiffness way to progress. 4. Low speed running smoothness to guide the small resistance, conflict movement is simple, no creeping phenomenon during low speed movement. 5. Structure in brief, to better guide the production and repair in usability, when applied to facilitate adjustment and maintenance.

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.
