Metal processing methods are various, of which metal cutting is the most common and widely used in metal processing. According to the workpiece shape, accuracy and surface quality of the different requirements, metal cutting can be divided into car, milling, drilling, planing, boring, reaming, broaching, gear cutting, thread processing and grinding. Cutting fluid is an important supporting material for metal cutting. It can be divided into cooling water soluble metal cutting fluid and lubricating oil based metal cutting fluid. Compared with neat cutting fluid, water-soluble cutting fluid has some unique advantages, such as better cooling effect, low cost of operation, less environmental pollution, can be used to place a potential fire hazard, so it has wide application. Here are some water soluble cutting fluid deployment and maintenance notes, for your reference:
First, cleaning and disinfection
In order to prolong the service life of the cutting fluid, adding new liquid before, please give equipment for cleaning and disinfection disinfection system comprehensively, can choose the system of special disinfectant disinfectant, according to certain requirements will be diluted in the internal circulation system for several hours to achieve the purpose of sterilization.
Two. Dispensing cutting fluid
1. Use a clean container to add the amount of water you want to deploy. (condition allowed, use auto mixer as much as possible)
2, the cutting fluid slowly into the water and stir evenly.
3, with refractometer measuring the new tune of cutting concentration, the initial concentration is recommended in 5%-10%.
4, cutting fluid pH value as far as possible to maintain between 8.0-9.6, if there is change, should find out the reason and solve.
Three, concentration adjustment
When the cutting fluid concentration changes, we need to add new liquid to adjust, and then adjust a certain concentration of cutting fluid and then add the machine.
Four. Maintenance of cutting fluid
1, the correct maintenance of the cutting fluid to ensure long life and good cutting function.
2, every day with refractometer to detect the concentration of cutting fluid, and timely adjustment, the correct concentration can ensure the stability of the cutting fluid.
3, prevent miscellaneous oil, sundries, especially food or cloth mixed into the liquid supply system.
4, timing skim oil, oil slick is a hotbed of anaerobic bacteria, if not removed in time, cutting fluid will soon stink.
5, if the machine downtime is too long, should add fungicides to prevent bacterial growth or regular cutting fluid circulation to destroy the anaerobic bacteria living environment.
