Rolling guide for CNC machining and cnc machining lathes in Dongguan _ What is the rolling guide for cnc machining lathes? In fact, Xiaobian does not understand.
So Xiaobian consulted Dongguan Hardware Products Co. , Ltd 【Huili hardware]
The company is specialized in manufacturing CNC machining, large-scale laser cutting, sheet metal machining and other precision equipment rack parts processing manufacturers.
Xiao Bian learned from the company that the rolling guide rail of cnc machining lathe is to arrange rolling bodies between the guide rail faces so that rolling friction between the guide rail faces. The rolling guide rail has a small friction coefficient (Generally at 0. 003 or so)
, Dynamic and static friction coefficient difference is small, and is almost not affected by motion changes.
It has the advantages of high positioning accuracy, high sensitivity and good precision retention.
About Rolling guide rails for cnc machining lathes: rolling island rails for cnc machining lathes there are two types of rolling guide rails commonly used in modern cnc machine tools: linear rolling guide rails and rolling guide blocks.
Let's analyze the difference between the two!
About linear rolling guide rail: linear rolling guide rail, also known as Unit linear rolling guide rail, is a new rolling guide rail in recent years, the structural type is composed of guide rail body, slider, Ball, Holder, end cover, etc.
When we use it, the guide rail is fixed on the unmoving part and the slider is fixed on the moving part.
When the slider moves along the guide rail body, the ball rolls in the circular arc straight groove between the guide rail body and the slider, and continuously circulates from the workload area to the non-workload area through the rolling channel in the end cover, thus, the movement between the guide rail body and the slider is turned into a ball rolling.

The master told me that the linear rolling guide is generally assembled by the manufacturer. Its outstanding advantage is that there is no gap. Compared with the rolling guide, it also has the following characteristics: high manufacturing precision; Second, it can maintain high precision for a long time; Three: pre-load can be added to improve stiffness;
Four: can run at high speed, the running speed can be greater than 10 m/s;
Five: it has self-adjustment ability, and the allowable error of the installation base surface is large.
Finally, let's take a look at the rolling guide block: the rolling guide block, also known as the rolling guide support block, is a rolling guide rail with a rolling body for cyclic motion, which is mostly used for medium load, the structural type is guided by the protective plate, the end cover and the guide piece (Roller)Return, then to the holder to the body.
When in use, the rolling guide blocks are installed on the guide rail surface of the moving parts. At least two pieces are used for each guide rail. The number of guide rail blocks depends on the length of the guide rail and the size of the load, the matching guide rails are mostly inlaid steel quenching guide rails.
When the moving part moves, the roller rolls between the guide rail surface of the supporting part and the body, and at the same time rolls around the body circularly, and the roller does not contact the guide rail surface of the moving part.
Rolling guide blocks are produced by professional manufacturers and have various specifications and types for customers to choose from.
The rolling guide block is characterized by high rigidity, large carrying capacity and easy disassembly. Okay.
