Numerical control lathe oscillation problem
numerical control lathe in machining process, has the fibrillation lines formed workpiece appearance, rework rate, high rejection rate, accompanied by a knife phenomenon. Oscillation is not only seriously deteriorated processing appearance quality, and it can shorten the lathe and the cutting tool life. So we it is necessary to take some measures to reduce or eliminate oscillation lathe attack. The following is said to cause oscillation problem of numerical control lathe. Products in the process of machining, guangdong produce CNC lathe manufacturer of CNC lathe onset of oscillation is very messy, the causes of oscillation are various, through analysis, first has the following several aspects: ( 1) The shape of the workpiece and disorderly and the clamping part choose inappropriate: workpiece contour structure rules, there is no good datum, not convenient clamping, the workpiece clamp is not tight, loose during the course of processing, simple corresponding oscillation with the change of the cutting force and attack. ( 2) Uneven workpiece internal organization: casting blank parts local defects such as porosity, sand holes, loose, coarse grains or containing impurities. Casting soft hard uneven cutting, tool uneven force, cutting force is not stable, easy to stir the CNC lathe attacks, sometimes forming a knife, the machining quality of workpiece is difficult to control. ( 3) Cutting tool selection is not reasonable: blade data is not appropriate, poor rigidity, is one of primary cause of oscillation. If choose the wrong tool, sometimes can make the tool wear increase or cause chip tumor, hair artifacts appearance or play knife cause oscillation and affect the quality of the product. When turning the low frequency oscillation, usually in the oscillation system of workpiece and tool holder system ( But the vast majority of cases the workpiece system oscillation is larger, plays a dominant position) , from them from time to time, and sometimes approach, attacks in the opposite direction from the intrusive flat action and reaction.

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.
