When processing thread on nc lathe knife
when we in thread machining with CNC lathe, chosen as a tool for cutting. In the large pitch screw machining, because of tool wear too fast, would amount to a machining after thread standard change big, low accuracy. Via exploring for many years, we explore a thread on nc lathe machining points of coarse and fine turning tool. In the machining process, after the rough turning blade abrasion to the limit, transfer finish turning blades to rough turning tools, finish turning tool from the beginning a new blade. This can ensure the machining accuracy of thread cutting together, also drop tool cost. The key depends on the method of coarse and fine thread tools for accuracy. 1, the operation method of end face and the cylindrical workpiece cutting a knife ( End flat, cylindrical) And then measure the outside diameter D, in coarse thread cutter. Specific methods are as follows: the rough machining cutter ( T0X00) With hand pulse generator for machining of cylindrical D first. With hand pulse generator in the direction of Z axis is rolled out to work, input values (D X axis of the knife knife) 。 Write down the X axis flash specific data. With hand pulse generator on the flash data recorded by the X axis feed towards negative 1 ~ 2 mm. Same with hand pulse generator in the negative direction of Z axis feed, cutting tool to the workpiece. Input Z0 ( The Z axis of knife) 。 When coarse threading tool of cutter. According to the method of screw thread finishing, operation process and rough turning cutter knife method thoroughly. So you don't disorderly buckle occur in the process of cutting. Even more cutting, the cutting tool are the same disorderly buckle phenomenon will not occur. 2, matters needing attention, 1) The knife on the X axis, the machine flash digital each are not identical. Must be good the practice of the cutting tool data recorded. After exit the X axis, the thread cutting tools X axis feed data must be the same, there can be differences. ( 2) In the process of the knife, close to the workpiece X axis and Z axis, hand pulse generator choice feeding 0. 001 mm range.

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.
