SamickSAMICKLinear guide efficiency The shape of the groove of the linear guide rail is varied in order to effectively realize its guide rail system,One is called Gothic when performing the operation(Pointed arch),The shape is an extension of the semicircle,The contact point is the vertex;The other is circular arc,It works the same way。No matter what kind of structure,Have only one purpose,Strive for more rolling ball radius contact with the guide rail(Fixed element)。
As everyone knows,Everything has its expiration date,That is, its service life。That today let Feng Ye share with you isHSKService life of linear guide

The function of linear motion guide is to support and guide moving parts,Reciprocating straight motion in the specified direction。 Installation procedure of linear guide rails: (1)、Before installing the linear guide, we need to remove the raw edge of the mechanical mounting surface、Dirt and surface scars。 notice: The linear slide rails are coated with anti-rust oil before formal installation,Before installation, we need to wash the base level with cleaning oil and then install it,Usually after removing the anti-rust oil,The datum surface rusts easily,Therefore, Feng Ye Xiaobian recommends applying lubricating oil for the spindle with lower viscosity。
The upper limit of the operating temperature of the general linear guide rail is80℃。If the environment used exceeds 80℃,It is recommended to use a special high temperature guide rail,High temperatures can be reached150℃,Transient high temperature200℃。
With the continuous development of modern manufacturing technology,The traditional manufacturing industry has undergone great changes,Numerical control technology、Mechatronics and industrial robots have been more widely used in production。At the same time, the positioning accuracy of the mechanical transmission mechanism、Guiding accuracy and feed speed are constantly improving,The traditional guiding mechanism has undergone great changes。Since the 1973Since the beginning of commercialization,The rolling linear guide pair has its unique characteristics,Gradually replaced the traditional sliding linear guide,It has been widely used in industrial production。Adapted to todays machinery for high precision、High speed、The requirement to save energy and shorten product development cycle,It has been widely used in various heavy-duty combined machining machines、Numerical control machine tool、High precision EDM cutting machine、Grinding machine、Industrial robots and even general industrial machinery。
GMTBasic requirements for linear guides,Have the following6Point requirement: (1)、Steering accuracy Steering accuracy refers to the accuracy of moving parts in a given direction in a straight line,It mainly depends on the geometric accuracy of the linear guide rail itself and the linear guide rail clearance。The geometric accuracy of linear guides generally includes:Straightness in vertical and horizontal planes;Parallelism between the surfaces of two linear guides。The geometric accuracy of the linear guide can be expressed by the error on the total length of the linear guide or the error on the unit length。
What Feng Ye Xiaobian wants to introduce to you today isNBThe characteristics and application field of linear guide rail: NBLinear guide rail is a linear transmission mechanism with high precision and high rigidity,Used to replace some rotating motion。 one、NBLinear guides have the following features:
Electric slides are widely used in various industries,Such as: 1、Entertainment industry:Robotic arms and joints,Dynamic seats and more。 2、Military industry:Simulated aircraft,simulation。
