Product Details
GM90 is a fully synthetic grinding fluid compatible with tungsten carbide hard alloys. It is produced with German * * * technology and process. Its * * * formula has excellent functions of cleaning, lubrication, cooling and rust prevention, and can prevent cobalt filtering and foam generation. Its anti impurity oil and stable antibacterial ability further extend the service life of the grinding fluid.
GM90 can be used in conjunction with German WENDT grinding machines, WALTER five axis grinding machines, HERKULES grinding machines, Swiss Schneeberger machining centers, and Italian POMINI grinding machines. It can also be used for rough grinding, semi precision grinding, precision grinding, and spark free grinding of tungsten carbide roller ring * * grinding machines manufactured by Suzhou Electric Machining Machine Tool Research Institute and Shanghai Grinding Machine Research Institute.
GM90 can eliminate the deformation resistance of the roller ring during high linear speed, high feed grinding with copper based diamond grinding wheels, and deep cutting of R-hole grooves, avoid overheating damage to the surface of the roller ring caused by high thermal strength and low thermal conductivity, and extend the service life of the roller ring. Its better protection for grinding machines and copper based diamond grinding wheels is reflected in the machining accuracy of ******, reducing the wear of diamond grinding wheels and the grinding of * * * and * * *.
GM90 is also suitable for efficient grinding of other types of hard alloys.

Introduction to the use of GM90 grinding fluid
High speed wire rods (stainless steel, cold heading steel, and other special steels) use tungsten carbide roller rings, diamond grinding wheels, and grinding fluid. The cost of the grinding fluid is negligible, but the effect it plays is astonishing. The correct selection and use of grinding fluid can invisibly reduce losses by millions of yuan. In recent years, there have been follow-up visits to over 200 steel mills using GM-90 grinding fluid. In these visits, many steel mill leaders have clearly pointed out that "improving the grinding efficiency of roller ring grinding machines and reducing diamond wheel wear are inevitably related to the grinding fluid
As far as we know, the guarantee rate of roller ring processing for each grinder isthirtyten thousand-10010000 tons of wire rods vary, with differences of * * *. For example, usingGM-90A certain steel enterprise with relatively normal grinding fluid,twoTable grinderoneCorrection machines, capable of ensuringtwo hundredRoll ring processing for 10000 tons of wire rod.

In contrast, invisibility has increasedtwo point nine twoelement/Tons of steel, according toone hundredWith a production capacity of 10000 tons, the grinding wheel has increasedtwo hundred and ninety-twoTen thousand.
The smoothness of the roller ring is directly related to the quality of the rolled product and the amount of steel passing through the roller ring. In our follow-up visit, we found that some steel mills, due to their lack of understanding of the technological content and importance of grinding fluid, do not mix it proportionally when using it or do not replace it on time. Some units use cheap grinding fluid to save * * *. Little did they know that improper use of grinding fluid can reduce the cutting ability of the grinding wheel, resulting in a significant decrease in grinding efficiency. For example: 1. The normal automatic feed amount of the roller grinder is 5 threads, but due to a mismatch in the grinding fluid, the actual grinding effect is only 1 thread. The remaining 4 threads will generate strong rigidity and push onto the grinding wheel spindle, causing an increase in grinding load. During grinding, the grinding wheel will bounce violently, producing noise, and the grinding wheel loss will increase several times. 2. Long term severe lateral vibration of the grinding machine spindle bearing can cause severe wear and distortion of machine tool accuracy. 3. After the grinding wheel jumps, there are ripples on the surface of the roller ring, resulting in poor smoothness. The quality of the rolled product and the amount of steel passing through the roller ring have significantly decreased. Many enterprises will not notice that the roller ring in grinding is caused by the decrease in smoothness due to improper use of grinding fluid. We found during a follow-up visit that some steel mills have the same rolling equipment and production specifications, but there is a significant difference in the amount of steel passing through the roller ring.

Calculation method for grinding fluid:
1The relationship between concentration and ratio. Some users mistakenly believe that the higher the concentration, the better. Generally, ordinary grinding fluid is represented by "concentration". For example, a concentration of 15% refers to the need for 15 kilograms of stock solution to prepare 100 kilograms of working solution. The "ratio" refers to the dilution ratio.
2Calculation method: * * * price per kilogram of working fluid diluted with grinding fluid= × Concentration.
For example, an imported grinding fluid costs 45 yuan per kilogram, with a usage concentration of 15% and a price of 6.75 yuan per kilogram. GM90 grinding fluid, 135 yuan per kilogram, with a concentration of 2%, priced at 2.7 yuan per kilogram.
