Question 2: Who knows what is an open guide rail 30 points Non-force closed guide rail, rely on self-weight, etc. to maintain contact, can only withstand a certain direction and size of the load.
The force closed guide is called closed guide, can carry loads in all directions.
See the following example:
Question 3: What is the guide rail for? The role of the guide is very large, but also divided into a variety of categories, each category role and use are not the same, but can correctly tell you that most of the automated electronic equipment now need linear guide.
Question 4: What brand of rail is good? Mainly depends on what you use in the place, Lun cost-effective, you can use on the silver, silver Thai, csk. Requirements for precision, you can consider thk--Anon Mall
Question 5: What is the guide rail of CNC machine tools? What are the classifications? CNC machine tool guide is to bear the weight of the table, ram and other moving parts and guide its movement of the components, like railroad tracks to support the weight of the train and guide the direction of progress.
The form of guideway is sliding, rolling, hydraulic guideway.
Problem six: linear guide is what material to do the installation size is the same go is a national standard. Materials are 55 steel. Only the same manufacturer's slider and guide can be interchanged. If it is an ordinary level of precision, who is cheap to buy who the quality can be used.
Question 7: mechanical guide rail is to play a guiding role? Then why are some called guide rail vice? Vice what does it mean? 1 is guided and positioning with
2 guide rail vice is the two components of the movement relationship
2 institutions in the various components of the relative motion between the must be determined, therefore, the connection of the components should be both direct contact between the two components, but also produce a certain amount of relative motion, this direct contact with the activities of the connection is called the movement vice. My understanding is that the vice is two relative motion to build the relationship between the composition, such as rotating vice, and high vice low vice, you look at the principle of mechanics, there is a description of the more simple
I hope to be able to help you
Problem eight: please ask who knows what guide is a displacement guide, and what is the difference between linear guide displacement guide is the adjustment of the relative position of the components between the adjusted fixed, in processing Does not produce relative motion. Has been the guide material and precision requirements are not high
Question 9: What is the guide error The accuracy of the linear guide can be divided into several aspects: walking parallelism, the height of the pairs of mutual differences and the width of the pairs of mutual differences.
Walking parallelism refers to the guide rail bolted to the reference surface, so that the slider in the guide rail running on the full length of the slider, the slider and the guide rail reference surface of the parallelism between the error.
The height of the pairs of mutual difference refers to the combination of the height of each slider in the same plane size of the maximum value and the minimum value of the difference.
The width of the pairs of mutual difference is mounted on a single guide each slider and the guide rail reference surface between the maximum and minimum value of the width of the difference between the dimensions.
Linear guide precision data is distinguished from the value of several indicators: there is a height of H size tolerance error, the height of H pairs of mutual difference, the width of the size of W tolerance error, the width of W pairs of mutual difference; slider on the surface of the lower surface of the slide rail walking parallelism, the slider side of the surface of the slide rail side surface of the walking parallelism, the length of the guide rail in terms of linear accuracy.
We often say that the accuracy of the linear guide usually refers to the walking parallelism, accuracy level is divided into (to guide 1000mm long for example)
Ordinary level (no label / C) 25μm
Advanced (H) 12μm
Precision level (P) 9μm
Ultra-precision (SP) 6μm
Ultra-super-precision (UP) 3μm. Grade (UP) 3μm
