What are the functions of machine tool guide rails

Machine tools require very high stroke accuracy and stiffness to ensure that the tool produces high-quality parts. The machine tool uses parallel guide rails. Usually, each guide rail has two bearing seats to ensure that the deflection is reduced.

Function of machine tool guide rail

The function of the machine tool guide rail is to ensure the accuracy and support of the workpiece or tool path. It can be said that the guide rail determines the basic accuracy of the machine tool and automation equipment. The main function of machine tool guide rail is to adapt to the axial movement of machine tool slider, worktable and spindle.

The main function of machine tool guide rail is to adapt to the axial movement of machine tool slider, worktable and spindle. The guide rail also provides geometric alignment of the axes. The surface must support static and dynamic loads with as little friction as possible, but at the same time, the influence of movable joints on the machine tool must be suppressed.

Machine tool guideway is a linear motion method mainly used to optimize the movement of materials, parts and components of workpiece. Through machining and precision design, these efficient track systems can achieve a smooth cycle. The advantages of machine tool guide rail are small friction, compact structure and easy installation.

What are the common guide rails for machine tools

Metal cutting machine tools require high precision. The guide rail is an important part of the feed transmission system of CNC machine tools. It also determines the rigidity and accuracy of the machine tool. The guideways commonly used in machine tools are hydrostatic guideway, sliding guideway and rolling guideway. The differences between these three guideways are relatively large.

Hydrostatic guideway can be divided into hydrostatic guideway and steam hydrostatic guideway. The disadvantage of the hydrostatic guide rail is that its structure is disordered, so the oil management system must be set, and the oil cleanliness is required to be high. Because the liquid has the function of vibration absorption, the guide rail has good vibration resistance; Large bearing capacity and good rigidity; The friction heating and temperature rise of the guide rail are low, but the structure of the hydrostatic guide rail is complex, and the cost of a set of hydraulic system is higher than that of other guide rails; It is difficult to keep the oil film thickness constant. Hydrostatic guideway is common in large or heavy CNC milling machines.

Function of machine tool guide rail

Sliding guide rail has a wide range of applications, because it has the advantages of simple structure, strong bending rigidity and high vibration resistance. Most of them use metal to plastic forms. Plastic coated sliding guide rail has good friction, wear resistance, low speed, smooth movement and good manufacturability.

The rolling guide is to place steel balls, rollers, needles and other rolling elements in the middle of the guide surface, so that the sliding contradiction in the middle of the guide surface becomes the rolling contradiction. The rolling guide rail has the advantages of small friction resistance, convenient movement, small damage, good precision maintenance and long service life.
