JSWAY | Leading CNC Lathe Manufacturer & Supplier Since 2007
Numerical control lathe spindle system fault diagnosis
common categories of nc machine tools to end more modern factory, medium and small batch of parts processing. Common nc machine tools are neway CNC lathe, milling machine and machining center, etc. To habits in nc machine tools of high automation, high plasticity, and the processing characteristics of high accuracy and rate of CNC lathe spindle system USES its unique methods and structure. The mechanical structure of the CNC lathe spindle: 1. Spindle ladder for a hollow shaft. 2. End of choosing short conic flange structure in collaboration with the chuck body; 3. After the spindle end first for equipment rotary oil cylinder; 4. Hollow spindle used by rotary oil cylinder piston rod; 5. Transmission methods are gear transmission, synchronous belt and belt mixed with gear transmission. Numerical control lathe electrical structure: 1. Drive for bridging nc equipment and spindle motor; 2. Completion of photoelectric pulse encoder, spindle speed real-time inspection, which constitute the main electrical control system; 3. Completion of rotary cylinder hydraulic control circuit, chuck jaw clamping and loosening. Nc lathe spindle system fault features: the main shaft system problems also can be divided into mechanical faults and electrical fault. Some mechanical structure as mentioned above, it is well known that a brief in the part of the problem is who often do the rotary motion, linear motion components, so find something wrong with parts should first preliminary from these parts. Vertical CNC processing base, for example, appeared to hold the cutting tool, should first check if broach rod stroke changes, due to broach rod during tool change again and again, often do linear motion. Some including spindle spindle system of electrical motor, drive, CNC equipment, spindle speed inspection equipment, parking equipment. Brief faulty is spindle motor, the spindle speed inspection equipment, must stop. Fault diagnosis method: generally speaking, a mechanical problems compared to short notice, and electrical fault diagnosis difficulty will be larger. Nc rotary working table commonly so judging mechanical some first whether there is something wrong with, then discriminant electric is some existing problems. First find out the machine tool spindle assembly from the mechanical structure, inspection of these components is normal or not. From experience, CNC machine tool spindle with large some of them are mechanical action failure cause. So, follow after the first mechanical electrical diagnosis method, generally can reach the role of get twice the result with half the effort.
Nowadays, it is very common for us to utilise in multi axis cnc machine. And the quality of is decisive to production efficiency.
If you already use cnc service elsewhere or want the ability to offer restricted chat access to certain individuals, cnc service mill axis offers you the most flexibility.
Zhongshan JSTOMI CNC Machine Tool Co., Ltd. has extented its range of manufacturing scale, which satisfys customers' needs.
We utilize our expertise to develop services that add value at each phase of thecnc service development cycle. We evaluate and implement new strategies in response to changing customer profiles and market conditions.
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.”
