Tips for VMC850 CNC Milling Machine Selection:
The choice of CNC milling machine mainly depends on the length of the workpiece, size, and processing mode, for precision processing, small and medium-sized batches and often periodically repeated production, the use of a CNC milling machine is very appropriate, if large parts, large mold precision processing, should choose gantry processing center. The milling machine with a high degree of automation replaces the common milling machine, reducing the labor of laborers, and the trend that raises productivity is inevitable. Our CNC milling machine has quality stability, Control quality from the source, and complete specifications, welcome to inquire.

The common guideway of the VMC850 CNC machining center?
The common guide rails of the CNC machining center include hard guideway and linear guideway. Therefore, our CNC machining center is divided into hard guide way machining center, a linear guideway machining center and two linear and one hard machining center. Customers can choose the appropriate type according to their own requirements. Generally, if the CNC machining center is used to make products, it will buy liner guideway. If it is processing molds, it will buy hard guideway. The accuracy of the linear guideway is higher than that of hard guideway, but the hard rails are stronger and more durable.
If the customer processes the mold with the CNC machining center, the hard rail shall be selected when the mold finish and precision requirements are not high, and the liner guideway with high finish and precision requirements shall be selected. The hard guideway is suitable for heavy cutting, and the linear guideway is suitable for high-speed light cutting.
Two Kinds of VMC850 CNC Milling Machine
According to the type of guideway.
Hard rail refers to the casting part in which the guide rail and the bed are integrated, and then the guide rail is processed on the basis of the casting. That is, the shape of the guide rail is cast on the bed, and then processed after quenching and grinding. There are also some guide rails that are not necessarily integrated with the bed and the guide rail. For example, the steel inlaid guide rail is nailed to the bed after processing.
The linear rail usually refers to the rolling guide rail, which is used in the linear module often used in the machine tool industry. We usually call this kind of component “linear guide rail”.
The linear guide rail itself is divided into sliding rail and sliding block. There are inner circulating balls or rollers in the slider, and the length of the slide rail can be customized. It is a modular component and a standardized series of separate products produced by special manufacturers. It can be installed on the machine tool and can be removed and replaced after wear.
Most machine tools in many finishing fields use high-precision wire rails as machine tool guide rails, which also greatly ensures the machining accuracy of machine tools. In fact, there is nothing good or bad about hard rail and wire rail. We can only say whether they are suitable or not. Let’s introduce the advantages, disadvantages and application fields of offline rail and hard rail.
Characteristics and application of hard rail
The hard guide rail belongs to dry friction, the sliding contact surface of the guide rail is large, the friction resistance during operation is large, and the moving speed is affected, which is slower than that of the linear guide rail. Because of its own structure, there will be gaps to affect the machining error of NC machining center. At the same time, it is easy to crawl. During the daily use of hard rail, attention must be paid to the daily maintenance. Once the track lubrication is insufficient, it will cause the track burning or excessive wear, which will have a great impact on the accuracy of NC machining center. Hard guide rail is especially suitable for heavy cutting because of its wide bearing range, good rigidity and strong seismic capacity. Hard rail machining centers are often used for large molds, high hardness workpieces and workpieces with general accuracy requirements.
Characteristics and application of track
The CNC machining center using linear guide rail can be very fast. After special treatment, there is no gap between the linear guide rails, so the accuracy is relatively high. In the same case, theoretically, the service life of linear guide rail is longer than that of hard guide rail. However, due to the limitation of its own structure, the weight of linear guide rail is much smaller than that of hard guide rail. However, with the development of science and technology, the load-bearing range of linear tamping plate is also gradually improving. Therefore, the linear guide rail is more suitable for CNC machining centers with high precision and high speed. It is especially suitable for the machining of small precision molds.
Which of the hard rail CNC machining center and linear rail machining center has a longer service life?
The service life of hard rail and linear rail of NC machining center is closely related to the actual use of customers. Generally, the service life of CNC machining center is about 7-10 years. If well maintained, it can greatly prolong the service life of CNC machining center. CNC machining center can carry out a precision maintenance every year, which is conducive to prolonging the service life of the machine.
What is two lines and one hard CNC machining center?
Two lines and one hard CNC machining center means that the XY axis guide rail of the machining center uses linear guide rail, while the Z axis guide rail uses hard rail; The XY of the two-line one hard CNC machining center uses the wire rail, which has the advantages of the wire rail, while the z-axis uses the hard rail, which also has the advantages of the hard rail. Therefore, the advantages of the existing wire rail of the two-line one hard CNC machining center also have the advantages of the hard rail, which can be described as killing two birds with one stone. However, since the two-line one hard CNC machining center has the advantages of the wire rail and the hard rail, it also has the disadvantages of the wire rail and the hard rail.
What is the difference between two-line one hard CNC machining center and three axis rail CNC machining center?
Three linear guide rail machining center refers to that the XYZ axis of the CNC machining center uses linear guide rail; In fact, the two CNC machining centers are not very different in essence, but there are still some differences in machining requirements. The biggest characteristics of the track are high speed, poor load capacity, high precision, low price, and the track can be disassembled and replaced; The biggest characteristic of hard rail is strong load capacity. The processing technology requirements of hard rail are extremely strict and the price is expensive. If the hard rail is integrated with the fuselage, the hard rail cannot be replaced; XYZ three-axis uses wire rail, which has the advantages of high speed, high precision, small friction coefficient, fast response, detachable replacement, etc. The disadvantage is that the load capacity is not strong and heavy workpieces cannot be processed. linear guide rail machining centers are generally small machining centers, while two linear one hard CNC machining centers have both advantages and disadvantages of hard rail and wire rail. Customers can choose their own machining center according to their own needs.
How to adjust the clearance on the guide rail of VMC 850 CNC machining center?
If the CNC machining center uses a linear guide rail, the clearance can be adjusted by changing the slider, If a hard rail is used, the gap can be adjusted by sticking plastic and inlaying strips.
