Japan THK linear guide rail slider SHW17CAM belongs to a wide track rail, the combined height is 17, and the symmetrical mounting hole of the slider is 53*26. THK linear guides are easy to assemble and interchangeable. THK linear guides are interchangeable. The slider or slide rail or even the CPC linear guide set can be replaced separately, and the machine can regain high-precision guidance.
Japan THK linear guide SHW17CAM rust solution revealed
Experienced CNC lathes and machining center operators must have met: the use of anti-rust cutting fluids in daily production, it is reasonable to say that the anti-rust effect is very good, and the anti-rust cycle between the processed products can reach the expected The effect is that the production equipment CNC lathes, the working table of the machining center and the guide rail often show rust marks.
The anti-rust performance of the processed workpiece is still acceptable. This can basically exclude the viewpoint that the cutting fluid has poor anti-rust performance, and can also exclude the rail corrosion caused directly by the cutting fluid.
This is due to the rail oil applied to the THK linear guide SHW17CAM door. The guide rail oil is usually composed of base oil mineral oil and some sulfur and phosphorus antiwear agents. During the circulation process, the cutting fluid contacts with the guide rail oil to produce a part of the oil-water mixture, that is, oil sludge.
The oil is lighter than water, and the oil absorbs most of the alkali and anti-rust components in the cutting fluid. The effect of water makes the THK linear guide SHW17CAM very susceptible to oxidation and corrosion.
This is not the main reason for the corrosion of the guide rail. The main reason is that the anti-wear agents such as sulfur and phosphorus in the guide rail oil are hydrolyzed by the main component of the cutting fluid, and the sulfur and phosphorus components are severely corrosive to the steel parts. This is the main cause of rail corrosion.
The way to solve the rust of the guide rail is either to change the water-based cutting fluid to oily cutting oil, emulsified oil or to replace the cutting fluid with a cleaning effect that is not particularly good, or to select the rail oil that uses molybdenum as the anti-wear material.
The above is about the solution of THK linear guide SHW17CAM rust, I hope it will be helpful to everyone!
