Car milling compound nc machine tool guide bearing is introduced
what car milling compound nc machine tools is the upper guide bearing? Is detailed to introduce below:

1, the role of the guide bearing:
car milling compound nc machine tool guide rail bearing set limits generator spindle is the purpose of the work, make its can only within the scope specified in the guide rail bearing clearance under radial load on the generator shaft.

2, the working principle of the guide bearing:
the working principle of thin oil lubrication bearing block type unit mainly in the high speed rotates, the use of lubricating oil into the combination of bearing and shaft neck surface to lubrication bearing, after oil cooler cooling, lubrication of hot oil into the combination of bearing and shaft neck surface again. With the operation of the unit, automatic cooling lubricants by reciprocating cycle. The spindle rotates, between the journal and bushing surface form stable oil wedge, bear radial load, and transferring them to guide on the bearing seat, and then transferred to the rack.
3, the structure of the guide bearing:
CNC lathe guide bearing is a kind of thin oil lubrication bearing, mainly composed of bearing cover, oil box, cooler, return pipe screw, bearing, bearing, load, thermometer, etc. B two units of standing guide sleeve is divided into eight guide bush, according to the circumference uniformly distributed on the generator shaft guide shaft neck.

4, bearing temperature increases in the cost and unit vibration analysis: by running the observation and analysis of maintenance, thought to cause the bearing temperature rise and the main reason for the vibration has two;
( 1) The increase of the bearing clearance is far greater than the design requirements of clearance, leads to the formation of a lubricating oil into the bearing bushing surface is not easy to oil wedge, cause poor lubrication, cause temperature rise of guide bearing, the vibration increases.
( 2) Shaft contact point on the surface of the ceramic tile is lesser, contact is not enough, do not conform to the requirements of the equipment specification.

5, the temperature rise of the guide bearing solutions
according to the manufacturer's design requirements, continuous running when the car milling compound CNC machine tools, high temperature of the cooling water is not more than 25 ° c, temperature and oil temperature of high temperature ceramic tile should not exceed 65 ° c. Wattage and the change of oil temperature is not only related to the temperature of the cooling water, and the cycle of lubricating oil and the clearance between the journal and the spindle axis. Numerical control lathe without the permission of the guide bearing clearance is 0. 2 to 0. 3 mm( Two-way clearance) , bearing lower into lubricating oil. When the main shaft clockwise operation, lubricating oil is easy to enter the guide bearing of the bearing surface and produce oil wedge. Lubrication of ceramic tile surface, even through the spindle big swinging point, although matching small gap, but due to the short distance, good lubrication condition, less friction heat, cooling effect is good, generally does not lead to bearing temperature rise phenomenon, also won't lead to ceramic tile burning.

On May 24, 2026, the production base of JSWAY CNC COMPANY welcomed teachers and students from Banfu No. 1 Middle School, Zhongshan City. This event combined campus education, family support, and the social responsibility of enterprises in Banfu. As a benchmark enterprise in the field of intelligent manufacturing in Zhongshan, JSWAY CNC COMPANY opens a door for students to enter the gateway of modern industrial civilisation.
The modern industrial system of the Banfu Industrial Park is being built at an accelerated pace, providing a continuous stream of momentum for the upgrading of intelligent manufacturing in the Greater Bay Area. As a “machine tool” enterprise — a true mother machine of industry — JSWAY CNC COMPANY resonates with the same frequency as the new industrial city of Banfu. By coming to JSWAY, the students, parents and teachers of Banfu No. 1 Middle School can experience the authentic face of high-end manufacturing.
In the workshop of JSWAY CNC COMPANY, Swiss‑type lathes ready for delivery undergo rigorous pre‑shipment inspections. Every machine must pass three levels of inspection – self‑inspection, cross‑inspection, and specialized inspection – followed by online laser inspection and finished‑product running‑in testing, before it can be loaded onto trucks bound for customers. The laser interferometer scans the guideways, the Renishaw ballbar checks roundness, and the coordinate measuring machine (CMM) touches every reference surface – only when all data show “green light” is the machine allowed to be shipped.
In the field of machine tool manufacturing, a well‑known saying goes: “Only a precise mother machine can produce precise machine tools.” As the “industrial mother machine,” a machine tool’s own manufacturing accuracy determines the precision of the parts it can produce. Over nearly two decades, JSWAY CNC COMPANY has forged a path toward quality based on the principle of “building top‑level machine tools with top‑level mother machines.”
