Trapezoidal screw materials:

 

1.General precision (referring to grade 7~9) Trapezoidal screws, for light loads, are usually made of non-alloy medium carbon structural steel (such as 45, 50 steel), normalized, quenched and tempered, or cold-rolled free-cutting steel (such as Y45MnV) Directly machined. For those with wear resistance requirements, quenched and tempered non-alloy structural steel (such as 45, steel) can be used, and it can be used directly after ammonia carburizing treatment. Screws used for measurement and with little stress can be made of quenched and tempered non-alloy structural steel (such as 45, 40Cr steel), which can be used after induction heating and surface quenching.

 

2.Precision (referring to level 6 and above) Trapezoidal screws are usually made of non-alloy (carbon) or low-alloy tool steel (such as T10A, T12A or 9Mn2V, CrWMn steel) for light loads, and are quenched and tempered or spheroidized annealed. Screws that work frequently are often made of low-alloy tool steel (such as 9Mn2V, CrWMn steel) and integrally quenched. They can also be made of high-grade nitriding special steel (such as 38CrMoA1A, 35CrMo steel) and undergo infiltration treatment to withstand high temperatures. temperature situation. Small-sized screws that require wear resistance can be made of carburized low-alloy steel (such as steel), and can be used after carburizing + quenching and low-temperature tempering. For screws that work at high temperatures, they can be made of precipitation-hardened stainless steel (such as OCr17Ni4Cu4Nb) and used after solid solution + aging treatment.

 

 

As an important moving component, linear guides are an indispensable component for many machines. So many customers need to install them by themselves after purchasing linear guides. What should they pay attention to when there are no technical personnel present? Let’s talk briefly today. You can consult our technical staff for specific operations.

The first thing to note is not to remove the slider from the guide rail at will. Normally, we ship the slider and the guide rail together, which means that the slider is of good quality, because there are balls inside the slider. If you take it out without paying attention, it may cause the balls to slip. If the ball is lost, the slider cannot be used. Generally, our manufacturer will be equipped with a slider push-off device to assist in removing the slider and reduce the occurrence of ball falling off.

 

In addition, disassembling the slider during assembly may cause dust and dust in the environment to fall in. After reinstalling, the motion may be stuck and the accuracy may be reduced, which is not worth the gain.

 

So before the formal installation, we must first carefully clean the installation location, remove burrs, dust and other dirt on the work surface, and keep the work surface smooth and tidy. In addition, it is necessary to apply anti-rust oil to the linear guide rail to prevent rust from affecting the normal function and performance of the product in future use.

Linear guide rails are usually fixed with bolts. Each model has a recommended bolt model. Customers are also asked to use the recommended sizes.

 

When fixing the bolts, be sure to tighten them and keep the track and the workbench close to each other without shaking. After tightening them all, drive the hole cover into the assembly bolt to keep it on the same level as the top surface of the linear guide rail.

 

There are some technical requirements for the assembly and installation of linear guides. We recommend that our customers find relevant technicians or consult the manufacturer for technical support during organization and installation.
