What are the characteristics of the quality guide post?
Jan 05, 2018

In the mold industry, guide post belongs to a more commonly used components.Usually when to install the component,  it with the help of a guide post to require the mold which is engaged in precise positioning to ensure to guide mold travel.Therefore, the guide post belongs to a commonly used guiding element.

For now, the main materials used in the production of guiding posts are 20Cr, 40Cr, SUJ2, and some are SKD11.So at the time of production, should meet what kind of performance?From the outside, the center has a hole is not obvious, and the roundness also have strict requirements.The reason is to make a hole in its center, mainly to be able to use external grinding machine to grind outside diameter.

Because during the process of making, it normally need to use a cylindrical grinder to grind its outer diameter.The center hole needs to resist by the top to ensure that the guide post could rotate to complete the grinding.For work can meet the demand of the strength and the diameter should be the fixed part of 1.5 to 2 times the diameter of the work area.

In addition, the better quality guide post also needs to have excellent lubrication performance. If necessary, a lubricating oil groove should be set.Also make sure that the roughness of the working surface shall not exceed 0.63 μm.Normally the working face not only needs to be wear-resistant, but also has a certain hardness to meet the work requirements.

Absolutely in use process, even quality guide post also need maintenance.Normally, its anti-rust performance should be better, or it may affect its accuracy.Generally speaking, its anti-rust performance is mainly affected by lubricants, such as the solubility of lubricants, the viscosity and so on will have different degrees of influence.

It is important to note that in the process of lubrication and maintenance of guide post, be sure to ensure the cleanliness of lubricating oil, but also pay attention to lubrication maintenance on a regular basis.In the process of changing lubricating oil and cleaning rust for the guide post, make sure to remove the original grease before applying the new lubricating oil.http://www.xhychromerod.com/
