The Cutting fluid Defender LIGHT / Coolant-lubricant fluid Defender LIGHT message appeared first on Novohim.

Defender Pro is a premium semi-synthetic water-miscible metalworking fluid for mechanical metalworking operations. The product is supplied as a concentrate and, after mixing with water, forms a working solution for turning, milling, drilling, grinding, boring, honing, bandsaw cutting, and other metalworking operations.
The main feature of Defender Pro is its high content of functional components and high oil content. It is not a “light” synthetic fluid and not a standard entry-level emulsol. It is a higher-grade semi-synthetic metalworking fluid intended for cases where the following are required:

• enhanced lubricating properties;
• better tool protection;
• clean machining and good surface finish;
• stable operation on modern equipment;
• suitability for more heavily loaded conditions than standard universal products.

What Defender Pro is

Defender Pro is a semi-synthetic metalworking-fluid concentrate with a high content of functional components. To understand the product logic, it is important that it contains a very large share of an active functional system, including mineral oil, fatty-acid soaps, and other functional components that form its lubricating, cooling, cleaning, anticorrosion, and operating properties.
That is why Defender Pro occupies a different position from low-cost basic emulsols or light synthetic products. It is a metalworking fluid for more demanding tasks where a balance of lubricating properties, stability, machining cleanliness, and tool life is required.

What class Defender Pro belongs to

Within the economy — standard — premium classification, Defender Pro belongs specifically to the premium class.
This means it is not focused on the lowest concentrate price, but on more demanding working conditions where the following matter:

• enhanced lubricating properties;
• working-solution stability;
• low foaming;
• use on modern machine tools;
• surface quality;
• machining cleanliness;
• long working-solution life when the system is properly maintained.

What Defender Pro is used for

Defender Pro is used for:

• cooling the tool and workpiece in the cutting zone;
• reducing friction between the tool and the metal;
• reducing cutting-tool wear;
• improving machined surface quality;
• stabilizing the cutting process;
• providing corrosion protection for equipment and parts;
• operation in machine systems with low, medium, and part of high-speed machining conditions.

Where Defender Pro is most appropriate

Defender Pro is most appropriate where the following are required:

• a semi-synthetic metalworking fluid with high oil content;
• enhanced lubricating properties;
• machining of stainless steel, high-alloy steels, cast iron, aluminum, and its alloys;
• use on CNC machines, automatic and semi-automatic equipment;
• stable operation under heavier conditions than standard universal emulsols;
• low foaming;
• long working-solution life without constant corrective additions.

The product is appropriate for use in:

• machine building;
• production of stainless-steel parts;
• production of agricultural machinery components;
• metalworking shops;
• modern CNC equipment;
• general-purpose machinery where not just basic but enhanced lubricating properties are required.

Suitable materials

Defender Pro is suitable for machining:

• carbon steels;
• alloy steels;
• high-alloy steels;
• stainless steels;
• cast iron;
• aluminum and its alloys.

The phrase “for all grades of steel, including super-hard grades” should not be used as an absolute claim. A more correct phrasing is: the product is suitable for a wide range of steels, including high-alloy and difficult-to-machine grades, but actual performance always depends on machining conditions, tooling, the specific operation, and the correctly selected concentration.

What machining conditions Defender Pro is intended for

Defender Pro is designed for a wider range of operating conditions than classic oil-containing standard-grade emulsols. It can be used:

• on low-speed machines;
• in medium-duty conditions;
• in part of high-speed machining conditions where a combination of cooling, lubricating properties, and solution stability is required.

This does not mean the product is equally suitable for any extreme machining condition without limitations. But in the premium semi-synthetic metalworking-fluid segment, Defender Pro has a strong position exactly where standard emulsols are already weak and light synthetics may fail to provide the required lubricating effect.

Main properties and advantages of Defender Pro

Main product properties:

1. semi-synthetic water-miscible metalworking-fluid concentrate;
2. high oil content;
3. high content of functional components;
4. enhanced lubricating properties;
5. low foaming;
6. suitability for more difficult operations and more heavily loaded conditions;
7. good machined surface quality;
8. clean part surfaces after machining;
9. stable working-solution life under proper operation;
10. corrosion protection;
11. suitability for modern equipment, including CNC machines.

One point should be emphasized separately: Defender Pro is not just a universal fluid, but a product with a strong focus on lubricating performance. This is what makes it effective for stainless steels, high-alloy steels, cast iron, and other materials where ordinary products may work less effectively.

What high oil content and high functional-component content provide

The high oil content and strong functional system in Defender Pro provide several practical effects:

• better boundary lubrication;
• lower tool wear;
• better surface quality;
• more stable performance in difficult operations;
• better suitability for steels and stainless materials;
• a higher working level compared with basic semi-synthetic or low-cost emulsion products.

This does not mean the product automatically outperforms any imported equivalent. A more accurate statement is: within its class, Defender Pro is designed for a high working level and can successfully compete with expensive products where lubricating performance, machining quality, and long solution life are important.

Practical operating experience with Defender Pro

In stainless-steel machining

In production trials, Defender Pro showed:
• high machining quality;
• good lubricating properties;
• stable working-solution performance;
• long service life in the system when concentration was controlled and operating practice was correct.

In production of agricultural machinery parts

Under production conditions, Defender Pro showed:
• reduced tool wear;
• high cleanliness of the machined surface;
• stable operation without pronounced foaming problems;
• long working-solution life without constant addition of corrective components.

On a bandsaw machine

During production trials on a bandsaw machine, Defender Pro showed a significant increase in saw-blade life compared with the product used previously. Under specific conditions, blade life was up to 2.5 times longer.
This result is explained by the combination of lubricating properties, working-solution stability, and the correctly selected concentration. The actual effect depends on:
• material;
• cutting conditions;
• blade type;
• machine condition;
• blade tension;
• operating conditions;
• correct working-solution management.
For that reason, this result should be treated as a practical production case, not as a universally guaranteed result for all conditions.

Recommended working-solution concentrations

• Turning: 3%
• Drilling: 4%
• Deep drilling: 5%
• Broaching: 3%
• Gear cutting: 5%
• Rolling and thread cutting: 5%
• Milling: 4%
• Boring: 3%
• Honing: 3%
• Bandsaw cutting: the working concentration should be selected according to actual cutting conditions, material, and machine operating mode.

Recommended concentrations may be adjusted depending on:

• material;
• machining conditions;
• tool type;
• system condition;
• supply method;
• water quality;
• actual operating load.

How to use Defender Pro correctly

To obtain a stable result, the following is recommended:

1. Fill the system with clean water.
2. Add the concentrate to the water.
3. Prepare a working solution of the required concentration.
4. Mix until homogeneous.
5. Supply the working solution to the cutting zone through the coolant system.
6. Check concentration with a refractometer during operation.

Before preparing the working solution, the concentrate must be thoroughly mixed until homogeneous.

Important note on water

The old text says that Defender Pro is easily prepared with ordinary tap water without additional treatment. That wording should not be left as an absolute claim.
A more accurate version is:
Defender Pro can work normally with ordinary tap water in many production environments, but actual water quality still affects working-solution stability, foaming, corrosion protection, and metalworking-fluid service life.
That means:
• it is not as water-sensitive as classic oil-containing emulsols;
• but it is still wrong to claim that water quality does not matter at all.

Storage

Defender Pro concentrate should be stored:

• in tightly closed containers;
• indoors;
• at temperatures from +5 °C and above;
• without freezing;
• without prolonged exposure to direct sunlight.

If you have a real upper storage limit of +40 °C, it is better to keep that as a separate technical parameter in the product card or technical data sheet.

Economics of use

At working concentrations of 3–5%, the cost of the ready working solution is many times lower than the cost of the concentrate. This is one reason why Defender Pro may be economically justified even when the concentrate itself is more expensive than simpler products.
The product should be evaluated not only by the price of the canister or drum, but by:
• solution life;
• tool wear;
• surface quality;
• consumption;
• system stability.

When Defender Pro may not be the best choice

Defender Pro should not be presented as the only correct product for all tasks.
In other cases, the following may be more appropriate:
• synthetic metalworking fluids, if the main criteria are system cleanliness, lower oiliness, and higher operating stability;
• specialized products for non-ferrous metals, if the main task is copper, brass, or bronze;
• narrowly specialized formulations, if the application involves extremely heavy conditions requiring special EP lubrication.
The strength of Defender Pro is not in a slogan like “for everything,” but in the fact that it is a premium semi-synthetic metalworking fluid with high oil content for serious metalworking.

Conclusion

Defender Pro is a premium semi-synthetic water-miscible metalworking fluid with a high content of functional components and a high oil content. The product is intended for modern metalworking where enhanced lubricating properties, good surface quality, low foaming, stable solution life, and suitability for more heavily loaded conditions than standard emulsols are required.
The product is most appropriate for machining steels, including stainless and high-alloy grades, cast iron, aluminum, and its alloys, as well as for operation on modern equipment, including part of CNC machines. When used correctly, Defender Pro provides not only cutting-zone performance, but also normal overall system stability.

The product is supplied as a concentrate and, after proper mixing with water, forms a working emulsion used for cooling the cutting zone, reducing friction, protecting equipment against corrosion, and stabilizing the machining process.
TUV-95 belongs to the category of traditional emulsols that retain practical value where enhanced lubricating properties, good machining cleanliness, good surface finish, and predictable operation on general-purpose equipment are required. It is not a synthetic or semi-synthetic metalworking fluid, so its main strength is lubrication, not maximum system cleanliness or minimum dependence on water quality.
TUV-95 is most appropriate for standard production tasks where a plant needs a proven oil-containing emulsol with reasonable operating economics, effective performance on steels, cast iron, and a range of hard metals, and predictable behavior in use.

Purpose

TUV-95 Emulsol is used for:

• cooling the tool and the workpiece in the cutting zone;
• reducing friction between the tool and the metal;
• reducing cutting-tool wear;
• improving the quality of the machined surface;
• facilitating chip removal;
• protecting equipment and parts against corrosion;
• stabilizing the cutting process.

Where it is used

TUV-95 is used:

• in machine building;
• in metalworking shops;
• in repair production;
• in serial and small-batch production;
• on general-purpose turning, milling, and drilling machines;
• on some CNC machines operating at low and medium cutting speeds;
• in centralized metalworking-fluid supply systems, provided that the system is properly maintained.

Main properties

Main properties of TUV-95:

1. classic oil-containing water-miscible metalworking fluid;
2. enhanced lubricating properties;
3. good machining cleanliness;
4. ability to achieve good surface finish when the concentration is selected correctly;
5. stable emulsion when prepared correctly;
6. corrosion protection for equipment and parts;
7. predictable performance under serial-production conditions;
8. low working-solution cost.

The strength of TUV-95 lies in the combination of lubricating properties, machining cleanliness, surface quality, and economical use of the working emulsion.

Materials for which it is used

The coolant is used for machining:

• structural steels;
• carbon steels;
• alloy steels;
• cast iron;
• stainless steels;
• aluminium alloys and certain non-ferrous metals, following production trials.

For steels and cast iron, this is a more typical field of application. For aluminum alloys and some non-ferrous metals, practical verification under actual production conditions is advisable.

For which machining conditions is Emulsol TUV-95 intended?

TUV-95 coolant is most effective at low and medium cutting speeds, when lubrication properties and tool protection are important.

Under such conditions, a classic oil-containing emulsion often performs better than some synthetic products when the main requirement is not maximum system cleanliness, but practical lubrication and a predictable result in standard machining.

For high-speed machining (HSM), modern machining centres and operations involving high heat generation, it is recommended to use semi-synthetic or synthetic coolants. For example, the semi-synthetic coolant Defender Pro or the synthetic coolant Defender Ultra.

Recommended concentrations of the working emulsion

The recommended values may need to be adjusted depending on the material, cutting parameters and production conditions.

Important note on water

As an oil-containing emulsol, TUV-95 is more sensitive to water quality than synthetic metalworking fluids. This is one of the key characteristics of the product.
For hard or problematic water, the following may be required:

• preliminary treatment;
• softening;
• mineralization control;
• adjustment of the emulsion-preparation procedure according to the actual water quality.

Unsuitable water may lead to emulsion instability, separation, deterioration of corrosion protection, and reduced service life of the working solution.

Operating features

For stable operation of TUV-95, it is necessary to:

• use metalworking-fluid systems with proper removal of chips, sludge, and abrasive particles;
• regularly remove mechanical contamination from tanks and circulation systems;
• control the concentration of the working emulsion;
• correct the concentration in time;
• maintain system cleanliness, especially in warm periods;
• avoid prolonged operation in a contaminated system
• store the concentrate in tightly closed containers at temperatures not below +5 °C.

Accumulated contamination accelerates biological activity, worsens emulsion condition, and shortens service life.

Important note before preparing the emulsion

Before preparing the working emulsion, the TUV-95 concentrate must be thoroughly mixed until homogeneous.
Simply rolling a 200-liter drum on its side does not ensure proper mixing of the concentrate. In that situation, the drum itself often rotates, while the liquid inside, due to inertia, mixes insufficiently.
For practical mixing under production conditions, a clean metal pipe or another suitable clean rod may be inserted through the drum opening. The concentrate should then be mixed with several circular movements in one direction and then in the opposite direction. This is far more effective than simply rolling the drum.

How to prepare the emulsion correctly

To obtain a stable working emulsion, it is necessary to:

1. Thoroughly mix the concentrate until homogeneous before preparation.
2. Not treat simple rolling of the drum as a sufficient mixing method.
3. If necessary, mix the concentrate through the drum opening with a clean metal pipe or another suitable clean tool.
4. Use prepared water or water suitable in quality.
5. Follow the recommended concentration.
6. Check concentration with a refractometer during operation.

IMPORTANT: when diluting, the concentrate must be poured into water. Water must not be poured into the concentrate.

Economics of use

One of the practical advantages of TUV-95 is the low cost of the working solution. With the correct concentration and normal system maintenance, the product allows a working emulsion with a clear and predictable cost structure, which is important for serial and small-batch production.
This is one of the reasons why TUV-95 remains attractive for enterprises that need not just a newer-sounding product, but a working emulsion with predictable operating cost
