CNC machining center is an automatic machine tool controlled by a program, which is currently widely used. Its performance and applicability are much higher than other CNC machine tools. Due to its high technical content and the many accessories involved, its price is also relatively expensive. As a user, when choosing a CNC machining center, when you don't know the price of the CNC machining center, you need to understand different · CNC machining center manufacturers. By asking different CNC machining center manufacturers, then roughly understand the price of the required CNC machining center, and then compare its after-sales service, at this time, the same quality ratio price, the same price ratio service. Budget for a price range that you can afford according to your processing needs.
First, the main configuration involved:
As we all know, the CNC machining center is composed of a number of core components and related connectors. If there is a problem in any link, the CNC machining center will not work. Therefore, the core components are the key and the main factor that determines the price:
1. Spindle: The spindle is a core component of the machine tool, which determines the accuracy of the machining surface of the workpiece, so the quality of the spindle is very critical. At present, the spindle brand produced in China is not commonly used in CNC machining centers, and the quality of domestic high-speed spindle units has not yet reached the requirements of machining accuracy. At present, the spindle unit of Taiwan brand is widely used, and different brands and market share are the main factors determining its price.
As a professional CNC machining center manufacturer, you can reasonably configure it according to the customer's requirements, and the specific details should be discussed in detail with the CNC machining center manufacturer before purchasing.
2. Ball screw: It is the most commonly used transmission element in precision machinery, and its main function is to convert rotary motion into linear motion, or torque into axial reversible force, and has the characteristics of high precision, reversibility and high efficiency. Its manufacturing technology content is relatively high, including material selection and assembly accuracy.
The ball screw determines the transmission accuracy of the equipment, and its material, accuracy, preload, cutting resistance, lubrication, load and other factors may cause the ball screw to wear out quickly, resulting in clearance or other irreparable problems.
The ball screws commonly used in CNC machining centers can be divided into P2/C2, P3/C3, P4/C4 (the smaller the number, the higher the accuracy), and a small number of CNC machining center manufacturers choose P5/C5, which is divided into rolling grade and grinding grade according to the process, and the accuracy of the latter is higher than that of the former.
