if you have any questions regarding your coolants or if you would like to discuss an onsite visit please give one of our team a call on 01924 869615.
Over the last 10 years, tooling technologies have become much more advanced, along with machinery. We push our tools harder than ever and expect the best performance, surface finish and the tightest tolerances. Often, coolant is overlooked in machining processes, but can actually play a key part in driving tool life, surface finish and sump life.
When selecting your coolant there are 3 main points to consider:
What machine are you operating - Are you on a manual machine/saw or a CNC machine?
What materials are you machining - Are you machining materials that are easily stained, or are you machining materials like Stainless Steel or Heat Resistant Super Alloys?
What is your geographical location - Are you in a soft water or hard water area?
Find out below what ranges of coolant are available and which materials/applications these are used for:
Milky white Water-soluble Coolant
Milky white water-soluble coolants work best in arduous conditions often found in manual machining, manual drills and saws. Milky white water-soluble coolants are often the most cost-effective options because of the low manufacturing costs, long life of the coolant, dilution rates and quality. These are a good all-rounder and will allow you to machine most materials with ease.
Our Cutsol M is the perfect option for manual machining, maintenance, and hobbyist machining. Dilution range are between a 3% and 10% reading on a refractometer.
Cutsol M is a traditional general purpose, high oil content, low odour, water soluble metal working fluid which forms a stable milky white emulsion when mixed with water. This is manufactured using highly refined paffinic mineral oils.
Cutsol M also incorporates additives, providing improved corrosion protection and bacterial resistance. To provide the highest degree of operator health and safety performance, it is free from Nitrite, Phenol, and Chlorinated additives. Dilution range is between 3% & 10% depending on application. Please consult our technical team to find out more.
Cutsol M is suitable for use on a wide range of applications such as Turning, Milling, Drilling, Sawing and griding of both ferrous and non-ferrous metals.
Semi synthetic coolants are the most popular option for anyone seeking the best tool life, improved surface finish and maximum sump life. In the semi synthetic range, you will find more options to suit the materials you machine or your geographical location.
Semi synthetic high-performance coolants offer improved performance, exceptional surface finish and sump life of up to 12 months if maintained properly.
These coolants feature special additives to keep the growth of bacteria to a minimum and eliminate bad odours which are often found in poorly maintained coolants. Dilution rates are usually between 4% and 12% depending on materials and product range. Below I have listed our main semi synthetic coolants.
High Performance Semi Synthetic Soluble Metalworking Fluid
Cutsol Ultra V7 is a high performance, heavy duty semi synthetic water mix metalworking fluid primarily suited to arduous machining and grinding operations and is designed to promote outstanding surface finish, improved tool life and exceptional machine cleanliness.
The product is low foaming, highly resistant to bacterial contamination and is suitable for use in soft to moderately hard make-up waters. Dilution range between 4% & 12% depending on application. Please consult our technical team to find out more.
Cutsol Ultra V7 is recommended for milling, turning, deep hole drilling, threading, reaming, tapping and grinding on difficult materials such as aluminium (including Aerospace 7000 Series), steel alloys, titanium alloys, Inconel, stainless steel and copper alloys.
Cutsol Ultra K2 is a multipurpose semi synthetic water-soluble metal working fluid designed to offer excellent performance in light machining and grinding applications.
It forms an extremely robust micro emulsion in both soft and hard water, providing excellent resistance against bacterial infections whilst reducing bad odours and improving the working environment. Dilution range between 4% & 8% depending on the application. Please consult our technical team to find out more.
Cutsol Ultra K2 offers excellent multi-material performance and is suitable for applications on materials including Steels, Stainless, Cast iron and Non-ferrous metals such as Aluminium and Brass.
Ultra Low Foam High Performance Semi Synthetic Soluble Metalworking Fluid
Cutsol Ultra LF is a high performance semi synthetic water mix metalworking fluid that produces a semi-translucent micro emulsion when mixed with water. It incorporates a unique combination of chlorine free extreme pressure additives providing outstanding machining performance and exhibits outstanding low foaming properties in very soft make-up water and high-pressure coolant systems.
The boron free formulation ensures excellent machine cleanliness and significantly reduces built up sticky residues on hard surfaces.
Dilution range between 4% & 10% depending on application. Please consult our technical team to find out more.
Cutsol Ultra LF offers high performance machining characteristics on a wide variety of tough ferrous and non-ferrous materials including Titanium, Aluminium (inc. 2000 & 7000 series) Nickel Alloys and Copper Alloys. Typical applications include heavy duty turning, milling, drilling, grinding, reaming and deep hole drilling where increased tool life and outstanding surface finish are desirable.
Hard Water Stable High Performance Semi Synthetic Soluble Metalworking Fluid
Cutsol Ultra HW is a high oil content semi synthetic metalworking fluid designed for use in moderate to difficult machining applications. It incorporates highly sophisticated chlorine free additive chemistry providing exceptional lubricity with improved surface finish and tool life. Cutsol Ultra HW provides outstanding bacterial resistance and a long, trouble-free sump life.
The product excels in moderate to hard water and offers rapid defoam performance at high pressures through tool coolant systems. Dilution range is between 5% & 10% depending on application. Please consult our technical team to find out more.
Cutsol Ultra HW is particularly suited to applications where maximum lubricity and non-staining performance is required, including the machining of 2000, 6000 and 7000 series Aluminium along with yellow metals. The product is also well suited to the machining of Titanium, Inconel, Nimonics and other exotic materials along with traditional ferrous and non-ferrous alloys.
It is paramount to ensure your coolant is diluted to the correct working range. This is for the safety of the operator and to ensure you get the best out of your coolants.
A refractometer is a portable handheld instrument used to measure the concentration levels of your coolant. You would take a sample from the machine by using a pipette and placing onto the lens/sample area. Once the daylight plate is closed you will look through the eye piece to see a scale.
By reading the line on the scale it will tell you what percentage your coolant is diluted to. If your coolant is too strong, please add water to dilute back to the correct level and if your coolant is too weak you will need to add more metal working fluid.
