JSWAY | Leading CNC Lathe Manufacturer Since 2007
Three methods of numerical control lathe spindle
the precision of the numerical control lathe spindle parts, rigidity and thermal deformation directly affect the machining quality. Because the numerical control lathe in machining process does not need manual control, the influence is more serious. The current numerical control lathe spindle mainly has three ways. Before the support by the double row short cylindrical roller bearing and 60 ° Angle touch of double row radial thrust ball bearing, bearing after equipped with radial thrust ball bearing in pairs. All stiffness of the spindle can be greatly improved, the structure can be satisfied the requirements of the chip, is widely used in small manufacturer of CNC lathe to make all kinds of CNC lathe. Front bearing using high precision double row angular touch ball bearing, bearing choose single row (after Or double row) Angle to touch the ball bearings. This configuration has a good function of high speed, but its bearing capacity is small, which is suitable for high speed, light load and fine numerical control lathe spindle. Before and after the double row and single row tapered bearings used in bearing. This constraint the recommend suite and precision of the spindle structure, suitable for the precision, low speed, heavy nc lathe spindle. Selects the step motor and MCU general lathe feed system formed by the transformation of the brief numerical control lathe the cost is low, but the degree of automation and function is poorer, turning accuracy is not high. Suitable for low requirements of rotating parts. According to the requirement of turning, the CNC lathe for special planning, and equipped with general CNC system. The numerical control system function strong, high degree of automation, high machining accuracy. Applicable to general inversion parts turning processing. CNC lathe can control together two axes, that is, the X axis and Z axis.
looking for the best deal while getting a quality is usually the number-one objective for most multi axis cnc machine manufacturer.

We believe in keeping the customers happy and providing them with cnc service at a very competent price.
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.
