Numerical control lathe spindle device structure
CNC lathe spindle ladder is a hollow shaft. Spindle hole for by long rods and unloaded at the top through the steel bar, also can be used by the organization of pneumatic, electric and hydraulic clamping device. Spindle front cone hole for the metric 90 mm, for device before the top cover and top. Sometimes can also be equipment spindle, the friction of the direct drive spindle using cone cooperation and workpiece rolling. Spindle backend cone hole hole for process. Numerical control lathe spindle equipment on the three bearing. Three of the top bearing roller bearing, front is 3182124 k of c-class precision type double row cylindrical roller bearings, used to bear radial force. This kind of bearing has good rigidity, high precision, small scale and large carrying to strength: after bearing to choose a pair of 7020 acta/P5DBB types of centripetal thrust bearing. Spindle bearing for numerical control lathe spindle has great influence on the working accuracy and stiffness, the numerical control lathe spindle bearing manufacturer (should be no gap Or a small amount of interference) Under the conditions of work, directly affect the machining accuracy of machine tool, so the spindle bearing gap must be regularly adjusted. Numerical control lathe to custom about front bearing gap adjustment method is as follows: first, loosen lock screw on the front end adjusting nut, then tighten the adjusting nut, at this time of the 3182124 k type inner ring is relative to the main shaft cone to the right, as a result of the bearing inner ring is very thin, and also like spindle cone hole, has 112 taper, thus, the inner ring radial elastic expansion in axial moving at the same time, to adjust bearing radial clearance or preload, adjust the secure, tighten lock screw to adjusting nut. The spindle radial runout and glaze to jitter tolerance are 0 0 imrrj. Numerical control lathe spindle radial runout of roundness and concentricity of the machined surface effects; The axial runout effect the precision of processing face flatness and pitch. In general, when the main shaft to beat more than promised, just right before the adjustment bearing, the gap can make main shaft runout quantifiers within the whole to the promised value; If the radial runout is still can not meet the requirements, should be adjusted after the bearings. Manufacturer of CNC lathe spindle bearing before and after the smooth, smooth oil pump is composed of oil supply, smooth oil through the oil hole on the bearing of smooth, and take away the heat generated by the bearing work. In order to prevent jiao oil, at the abutment before and after chose oil groove seal, namely in the front on the surface of the nut and bearing sleeve after has a circular groove of the section, the sawtooth CNC lathe spindle rotates, due to the effect of centrifugal force, the oil is along the inclined plane ( In the direction) Be left to the flange of oil tank, oil through the oil return orifice flow to the bottom, and then flow back to the oil pool in the left leg.

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.
