Jokisch NBK

Design:

Jokisch NBK is an easy emulsifying, transparent, synthetic, water soluble concentrate. It has been designed almost exclusively for grinding applications. It addresses the concerns of grinding, keeping stones (grinding wheels) clean and free, while containing strong corrosion inhibitors to prevent rust. Jokisch NBK has an extremely stable and long life, which reduces dumping as well as provides a safe working environment. Jokisch NBK keeps machinery clean and does not affect machine paint. NBK is also utilized as a dip/spray-on rust inhibitor.

Safety:

Jokisch NBK contains no hazardous ingredients and is chemically balanced. Jokisch does not use or need hazardous biocides. They are sometimes called perfumes, deodorizers or tea bags to control rancidity or to keep the coolant stable. NBK is chlorine and sulfur-free.

Performance:

Jokisch NBK is manufactured to provide a maximum cooling effect while grinding all materials, especially carbide, graphite, glass lenses, and other optic related materials.

pH:

Jokisch NBK has a pH between 9.0 - 9.5. This prevents rusting of machine, fixtures, and parts. Jokisch NBK can also be used as a corrosion inhibitor at a 2% mix (1:50)

Foam:

NBK has very strong anti-foaming agents. This lends itself well to blanchard and creep-feed grinders which require a strong anti-foaming coolant for maximum performance during high pressure coolant feeds.

Consumption:

Jokisch NBK does not evaporate due to its unique formulation which reduces coolant consumption by 50% or more. Water must be replaced and a refractometer (RHB-32) is recommended for proper coolant maintenance. A 1:35 - 1:50 part water mix ratio is optimum with a "top-off" mix suggested at 1:80.

Disposal:

Jokisch NBK is extremely stable and as such will not need to be disposed of as often. Changing the coolant once a year or using an extremely efficient filtering system is highly recommended. Jokisch NBK is chlorine-free which reduces disposal costs.
