CNC Coolants
Water Miscible
Water-miscible coolants are the most widely used metalworking fluid in CNC machining environments. When mixed correctly with water, they provide excellent cooling, lubrication and corrosion protection — extending tool life, improving surface finish and keeping your machines running efficiently.
At Technical Fluid Solutions, we supply a range of premium water-miscible coolants formulated for the demands of aerospace, medical and motorsport machining — where tolerances are tight and fluid quality is non-negotiable.
Benefits:Excellent cooling properties for high-speed CNC operations. Reduced tool wear and extended tool life. Improved surface finish on critical components. Formulated for use with aluminium, titanium, steel and exotic alloys. Low foaming — suitable for high-pressure through-tool applications. HSE-compliant formulations that are safer for your workforce.
Industries served:Aerospace machining, medical device manufacture, motorsport engineering, defence subcontracting and general CNC machining.
Neat Cutting Oils
Neat Cutting Oils for Precision Machining
Neat cutting oils (straight oils) are used where water-based coolants can't cope — deep-hole drilling, threading, tapping, broaching and honing, and machining difficult alloys like titanium and nickel-based superalloys. With no water content, there's no dilution to manage and no bacterial contamination risk, which is one of the most common findings behind HSE coolant complaints.
At Technical Fluid Solutions, we supply neat cutting oils formulated for the demanding tolerances used across aerospace, medical and motorsport machining.
Key benefits: Superior lubricity for heavy-duty and difficult-to-machine operations. No bacterial growth or rancidity — no routine dip slide testing required. Excellent surface finish on deep holes and threads. Suited to titanium, nickel alloys and other exotic materials.
Industries served: Aerospace machining, medical device manufacture, motorsport engineering, defence subcontracting and general CNC machining.
Hydraulic Oils
Industrial Hydraulic Oils — Reliable Performance Under Pressure
Hydraulic oils keep the clamping, tool-change and work-holding systems on your CNC machines running smoothly and reliably. The right viscosity and additive package protects pumps and seals, prevents overheating, and keeps pressure consistent under load.
At Technical Fluid Solutions we supply UK-manufactured hydraulic oils suited to the machine tool brands used across aerospace, medical and motorsport machining.
Key benefits: Consistent viscosity across operating temperatures. Protects pumps, valves and seals from wear. Reduces the risk of unplanned downtime. Compatible with major CNC machine tool hydraulic systems.
Industries served: Aerospace machining, medical device manufacture, motorsport engineering, defence subcontracting and general CNC machining.
Slideway Oils
Slideway Oils for CNC Machine Tools
Slideway oils — also known as way oils or machine tool lubricants — are specifically formulated to lubricate the guideways, ball screws and slideways of CNC machine tools. Using the correct slideway oil is essential for precision, smooth axis movement and protecting your machine investment.
Technical Fluid Solutions supplies premium slideway oils compatible with all major CNC machine tool manufacturers including Mazak, DMG Mori, Haas, Doosan and Fanuc-controlled machines.
Key benefits:Protects guideways and ball screws from wear. Ensures smooth, precise axis movement. Prevents stick-slip on machine slideways. Compatible with all major CNC machine tool brands. Extends the working life of your machine tools.
Industries served:Aerospace machining, medical device manufacture, motorsport engineering, defence subcontracting and general CNC machining.
Anti-Corrosion Products
Anti-Corrosion & Rust Prevention Products
Machined components — particularly in aerospace and medical manufacturing — require protection between operations and during storage or transit. A single rust spot on a precision-machined part can mean rejection, rework and reputational damage.
Technical Fluid Solutions supplies a range of anti-corrosion products including water-based rust preventatives, solvent-based inhibitors and long-term storage compounds — suitable for ferrous and non-ferrous metals.
Key benefits:Protects machined components between operations. Prevents rust during storage and transit. Suitable for ferrous and non-ferrous metals. Available in water-based and solvent-based formulations. Ideal for aerospace, medical and defence components where surface quality is critical.
Industries served:Aerospace machining, medical device manufacture, motorsport engineering, defence subcontracting and general CNC machining.
CNC Machine Tool Cleaning
Professional CNC Machine Tool Cleaning & Coolant Installation
If you've had an HSE visit or an Improvement Notice about your machine tool coolant, a professional clean and coolant changeover gets you back to compliant fast. We remove bacterial contamination and tramp oil from your sump and coolant lines, then refill with correctly mixed, fresh coolant — with dip slide test results and documentation you can show an inspector.
Key benefits: Removes bacterial biofilm that standard flushing misses. HSE-ready documentation and dip slide testing. Reduces dermatitis and respiratory risk for operators. Extends coolant and machine life.
Industries served: Aerospace machining, medical device manufacture, motorsport engineering, defence subcontracting and general CNC machining.
HSE Compliance & Dip Slide Testing
HSE Coolant Compliance & Dip Slide Testing
Regular dip slide testing is what HSE guidance expects from any workshop using water-miscible metalworking fluids — and it's usually the first thing an inspector asks to see. We set up and run an ongoing testing schedule for your coolant, so bacterial contamination is caught early and you've got a documented record ready before an inspection, not scrambled together after one.
At Technical Fluid Solutions, we build fluid management programmes around your machines, testing frequency and record-keeping — matched to the standards aerospace, medical and motorsport manufacturers are held to.
Key benefits: Scheduled dip slide testing and bacterial contamination monitoring. Documented fluid management records ready for an HSE inspector. Early warning before contamination forces a full machine clean. Reduces dermatitis and respiratory risk for your workforce.
Industries served: Aerospace machining, medical device manufacture, motorsport engineering, defence subcontracting and general CNC machining.
Filtration, Mixers & Fluid Distribution Systems
Coolant Filtration, Mixers & Fluid Distribution Systems
Contaminated coolant, worn filters and poorly maintained mixing units are a common root cause of the bacterial growth and fluid failures that trigger HSE concerns. We supply and service the filtration, automatic mixing and central fluid distribution systems that keep coolant clean and correctly concentrated at every machine, not just at the sump.
At Technical Fluid Solutions, we specify, install and maintain filtration and distribution systems suited to aerospace, medical and motorsport machining environments, where fluid quality can't be left to chance.
Key benefits: Removes swarf and tramp oil before it degrades your coolant. Automatic mixing keeps concentration consistent across every machine. Central distribution reduces manual handling and waste. Fewer contamination-related HSE findings.
Industries served: Aerospace machining, medical device manufacture, motorsport engineering, defence subcontracting and general CNC machining.
About Us
Why Engineering Companies Trust Technical Fluid Solutions
At Technical Fluid Solutions, we understand that the right fluid isn't just a consumable — it's a critical part of your production process. Poorly managed coolants and lubricants cost you money through increased tool wear, unplanned downtime, HSE compliance failures and scrapped components.
We work directly with engineering companies operating in some of the most demanding sectors in the world — aerospace, medical device manufacturing, motorsport and defence — providing the industrial fluids, onsite services and fluid management systems they need to run cleaner, longer and more profitably.
