How Many Types of Guideway Oil Are There?
2 Answers
The viscosity of guideway oil is primarily selected based on the load conditions. Generally, heavier loads require higher viscosity, while lighter loads require lower viscosity. Here are the specific details: 1. Types of guideway oil: There are 4 types of guideway oil, namely 32, 46, 68, 100, and 220. 2. Main functions: The viscosity of guideway oil is chosen according to sliding speed and average pressure. The viscosity of guideway oil is equivalent to the two types of guideway oils L-G68 and L-G150 (equivalent to the old grades 40 and 90) and the two guideway-hydraulic oils L-HG32 and L-HC68 (equivalent to the old grades 20 and 40) recommended in the international standard GB7632: Selection of Lubricants for Machine Tools. 3. Application scope: It can be used to lubricate screws, linear guideways, spindle boxes, translation screws, cylindrical and conical gears, and light-load worm gear transmission devices.
There are indeed countless models of guideway oil. From my experience in maintaining machine tools, brands like Mobil and Shell each have their own series. Mobil offers viscosity grades such as VG22, VG32, and VG46, with the VG series alone ranging from 22 to 220, covering dozens of variants. Additionally, there are different types like rust-proof, anti-wear, or high-temperature-specific oils, with each brand likely offering over 50 models. Selection should consider the guideway material and operating environment—for example, a high-temperature workshop might require VG68 high-temperature oil. Oil compatibility is also crucial; cleaning the guideways before changing oil can extend their lifespan. Don’t just focus on the numbers; the key is to follow the equipment manual, as improper selection can lead to rust or accelerated wear. Regular oil level checks also help prevent issues.
