I believe that many friends all know, CNC high-speed machine rail performance is good or bad, will directly affect the machine's machining accuracy, load capacity and performance, so CNC high-speed machine rails than ordinary machine tool rail requirements are higher; but the rail as a feed system Of the important links, different types of machine tools, the requirements of the guide rail is also different, then the user how to choose? What are the commonly used rails? The following by the World technical staff to tell you:
CNC high speed machine
In the choice of CNC high-speed rails, to meet these basic requirements: high-speed feed does not occur when the vibration, low-speed feed does not appear crawling phenomenon, high sensitivity, good wear resistance, continuous long-term heavy load, Maintain good and so on. We can according to their own needs for the above requirements to select the machine tool guide. Common guide rails in the form of sliding rails, rolling rails and hydrostatic rails.
The same time as the above-
(1) sliding rail: sliding guide with a simple structure, easy manufacturing, good stiffness, strong seismic, etc., in the general application of the most widely used machine, often made of cast iron or steel rails.
The same time as the above-
(2) rolling guide: rolling guide rail is installed between the rail surface rolling body, the rolling body can ball, roller and needle, and the contact between the guide for the point of contact or line contact, so the friction coefficient of the guide Small; wear small, good precision retention, long life and other advantages.
The same time as the above-
(3) hydraulic rail: CNC high-speed machine used on the hydraulic rail is mainly hydrostatic guide. Static pressure rails are usually in the two relatively moving guide surface between the pressure oil, so that moving parts float. The oil pressure can be adjusted automatically with the change of the external load to ensure that the rail surface is always in the friction state of the pure liquid. Therefore, the friction coefficient of the static pressure guide rail is the smallest and the power consumption is small.
The same time as the above-
The above is to share with you today, compared with ordinary machine tools, CNC high-speed machine with a numerical control system (program control system), through the preparation process to achieve automated processing, it is widely used in precision hardware, consumer electronics Such as processing industry.
