Box Guideway Machining Centers
Box guideway machining center also call hard rail machining center in China, it refers to a casting part where the guide rail and the bed are integrated, and then the guide rail is processed on the basis of the casting, which is a type of hard guide rail. The shape of the guide rail is cast on the bed, and then processed into a guide rail through quenching and grinding. The hard rail used in the hard rail machining center is generally a rectangular structure, commonly known as a rectangular guide rail or box guide rail. The Box way machining center machining center adopts sliding friction, which leads to a larger contact surface and high rigidity and strength. Therefore, the box guideway machining center is more suitable for heavy-duty cutting and is suitable for heavy-duty mold processing.
Advantages of box guideway Machining Centers:
1. Able to withstand larger loads, suitable for rough machining machines with large cutting amounts and large feed rates.
2. Due to the large contact area of the guide rail, the machine tool operates more smoothly, making it suitable for factories with high requirements for machine tool vibration.
Disadvantages of box guideway machining centers:
1. Shorter service life. Under the same maintenance and usage conditions, the service life of box guideways is generally shorter than linear guide machining center, because box guideways operate with sliding friction, while linear guide operate with rolling friction, resulting in greater wear and tear.
2. The repair cost is too high. The maintenance of box guideway machining center is much more difficult and costly than linear guideway machining center. If there is insufficient scraping allowance, it may involve disassembling all the large parts of the machine tool, performing quenching and mechanical processing again, and even more importantly, recasting the large parts. The wire gauge only needs to replace the corresponding linear guide, which will not greatly affect the use of related large parts.
3. The running speed of machine is low, and box guideways machining center usually cannot withstand too fast running speed due to their movement mode and the excessive friction they bear, which contradicts the current machining concept to a certain extent. Especially many factory workers do not have the corresponding maintenance knowledge for machine tools. Many times, they only know how to use the machine tool, but largely neglect the maintenance of the machine tool. The maintenance of the machine tool track is of utmost importance. Once the lubrication of the track is insufficient, it can cause the track to burn or wear excessively, which is fatal to the accuracy of the machine tool.
