JSWAY | Leading CNC Lathe Manufacturer Since 2007
Maintenance 101 For CNC Lathe Machine Shops
CNC lathe manufacturing is widespread throughout the component manufacturing industry worldwide as more and more demand is placed on higher production, lowered costs and increased quality requirements on industrial manufactured components. Several companies, however, turn to the deployment of used CNC lathes as a means to reduce their capital equipment costs. While this is a help in improving the bottom line of many companies, the down side of this method is that one has be very vigilant when it comes to keeping these pieces of equipment in proper working order so that production schedules are not compromised and quality levels are not sacrificed. This means that there is increased pressure on maintenance personnel to establish and follow proper courses of action. In this article, we will describe the three basic maintenance procedures that come into play in CNC lathe machine shops.
The first step involves routine maintenance. In this procedure, one schedules a frequency, be it every day, every so many days, every shift or any other frequency depending upon the age of the machines and the demands of the shop. Routine maintenance procedures may involve changing coolants, cleaning chip pans, inspecting and adjusting safety mechanisms, changing or filling hydraulic oil, etc. and their goal is to try to prevent breakdowns.
The second maintenance procedure involves preventative maintenance. Preventive maintenance involves inspecting belts, adjusting, repairing or replacing components that have not yet failed but are known to fail within a short period. Preventive maintenance involves developing a history of breakdown of components from past history, allowing for catching of problems before they happen.
Finally, breakdown maintenance procedures come into play when a component has already failed, thus shutting the production line down. As one can imagine, this type of action can be very costly due to down time involved in production that can get aggravated if the necessary replacement parts are not readily available.
One needs to strive to avoid breakdown maintenance as much as possible by concentrating on routine and preventive maintenance procedures because the latter two are significantly less expensive than the former.
In the present growing world of emerging technology, the has demanding operation in various sectors like mill axis, multi axis cnc machine, mill axis and many other industries at multi axis cnc machine levels of manufacturing and designing.
We believe our capacity can give you an impressive experience by using cnc service.
Regularly improving cnc service in accordance with customer feedback is a great way to show your brand listens and cares.
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.
