Reducing water content in hydraulic oil – increasing quality

HYDAC - your partner for efficient hydraulic solutions in grinding machine.
In the grinding process, precision is the top priority. First and foremost, this calls for powerful and clean machining fluids and lubricating fluids. In practice, water-based coolants are sometimes used. This can lead to problems in the grinding process if the water-based coolant is able to bypass the seals and mix with the hydraulic fluid used as track lubrication. This can result in corrosion and rust on the machine guides, which leads to a drop in quality in the machined workpieces. The high water content also gives rise to very short oil service lives, meaning that the oil needs to be changed frequently, with high service costs.

For these reasons, machine operators are increasingly pressuring grinding machine manufacturers to come up with an efficient and cost-effective solution for keeping the water content in the hydraulic fluid consistently low.
