JSWAY | Leading CNC Lathe Manufacturer Since 2007
The structure of the ordinary lathe
the first components of ordinary lathe: spindle box, feed box, slip board box, head and tail frame, light poles, screw and lathe bed. Spindle box: also called headstock, its priority is the main motor rotation after a series of variable speed from the organization make main shaft gets the positive and negative two turns to the different rotating speed, spindle box together gives impetus to the movement into the box. The spindle box medium spindle is the key of the lathe parts. Spindle bearing on operation stability directly affect the machining quality of workpiece, when reduced, the spindle rotation accuracy is the use of the machine tool value will fall. Feed box: also called feeding box, feed movement are installed in the feed box shifting organization, to adjust its transmission organization, can get the required feeding or pitch, after light poles or screw would transmit the motion to head for cutting. Screw and light poles: to join feed box and slip board box, and the movement of feed box and the power to slip board box. Plate box vertical linear motion. Screw is specially used for cutting all kinds of screw thread and setting, when the other into the workpiece surface turning, only the light, and there is no screw. Slip board box: lathe feed movement control box, in which the light poles and tool carrier of screw rotation movement into linear motion, after light bar transmission to realize tool slide transverse and longitudinal feed movement of the feed movement and fast moving, and through a lead screw drive tool post for vertical linear motion, so that the thread cutting. Head: the tool rest component is composed of several layers of rest, it is the function of the clamping tool, make the knives for vertical, horizontal or diagonal feed movement. The tailstock: equipment after the top, can also be used as positioning to support equipment drill, reamer hole machining tool for machining. Lathe bed: in each primary parts, equipment and lathe bed body makes them insist on accurate relative position in the job.
The use of multi axis cnc machine cnc service is a great trend in today's world. What you should know is that it has become a very important part of business today.
We are proud to be one of the largest suppliers out there. You will love what we offer for your cnc service solution. Check our website at JSTOMI CNC Machine or call to talk to our customer service department with any questions you may have.
mill axis needs not be tedious anymore with the application of . So getting the right cnc service can drastically promote multi axis cnc machine.
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.
