The service life of the linear guide rail depends on the manufacturing quality, structure, material and heat treatment of the guide rail.
1. Support plate: The type support plate has a simple structure, and the workpiece is in contact. It is easy to manufacture, but it is not easy to remove the chips from the hole, so it is suitable for positioning on the side and top surface. Because the profile has a chute, it is easy to remove the chips, and it is easy to ensure that the working surface is clean, so it is suitable for bottom surface positioning.
2. Support nail: Generally, a support nail only restricts one degree of freedom. A blank plane can only be positioned with three ball-head supporting nails to ensure that the contact point is determined, and three or more flat-head supporting nails can be used for positioning to make the positioning stable. If the workpiece is positioned on the machined plane. However, it is necessary to ensure that the positioning working surfaces of these flat-head supporting nails are in the same plane, otherwise, the supporting nails will not be all and the positioning will be unstable.
3. Adjustable support: the selection method of the linear guide rail at the support point and the determination of the rail width in consideration of parameters can more accurately ensure the parallelism of the silver guide rail during use and increase its wear resistance!
