What is the role of the grooves in the guide column
Located, and there is an inverted Angle, preventing the separation of the positioning column from the module
Storage of lubricating oil and cutting groove action. Because of the relative motion of the guide when the guide is working, because the clearance is small, the oil can be scraped off for a long time. So the design of this groove allows the lubricant to stay on the length of the guide column, not all of it to the end. Because the processing accuracy is different on both sides of the guide. Level 2 orientation precision, for example, sliding guide part of guide pillar and guide bush of requirement is H7 / h6, guide pillar of the fixed part and the mold base with the mounting holes is H7 / s6, relief groove guide pin can be divided into two sections, one section for h6, another for s6, so relief groove is a must have!
We usually call it "tank." You can touch the butter in it! At the time of the mould, touch the butter, lubricate and extend the life of the guide column.
The lubrication oil groove of the guide and guide on the mould is on the guide sleeve, the die is lubricated by the oil gun to the guide and the guide sleeve, and prevents the death from biting.
