SO-32 / 46 / 68 Slide Way Oil: Specialized Lubrication Solution for CNC and Grinding Machines
In precision mechanical processing, even a small vibration on the guide rail can damage the surface finish or cause dimensional deviations in parts. SO Series Slide Way Oil (SO-32, SO-46, SO-68) from the brand TP Oil is formulated to meet the most stringent requirements of modern CNC and grinding machines.
1. Optimized for high-speed grinding and CNC machines
Unlike the common SR series, the SO-32 / 46 / 68 line features extremely fast separation from coolant (cutting fluid). This prevents emulsification of the lubricant, keeping the oil film on the slide way pure, thereby protecting the guide rail surface from chemical corrosion and ensuring extremely stable machine table movement.
2. Outstanding advantages of TP SO slide way oil
The product is preferred by mold and precision part workshops due to:
-
Perfect anti-stick-slip capability: Ensures smooth machine table movement even at extremely low speeds, completely eliminating localized jerking.
-
Excellent compatibility with cutting fluid: Oil easily separates from coolant, extending the life of both the lubricant and the water-miscible cutting fluid.
-
Metal surface protection: Contains a powerful anti-wear and anti-rust additive system, maintaining the gloss and flatness of guide rails for a long time.
-
Good adhesion: Creates a durable oil film on vertical surfaces without dripping, significantly saving oil consumption.
-
Chemical stability: Does not produce unpleasant odors and does not degrade sealing materials (seals/gaskets) in the CNC lubrication system.
