Metalworking Fluids and Oils: Efficiency, Tool Life, and Process Reliability
Fluids and oils used in metalworking processes are not merely auxiliary products used for cooling or lubrication. Selecting the correct metalworking fluid has a direct impact on tool life, surface quality, dimensional accuracy, production speed, energy consumption, and overall process cost.
GataMerk supports businesses' production continuity and process reliability by offering metalworking fluids, pure cutting oils, and after-sales technical support solutions for different production processes and material types.
What are Metalworking Fluids?
Metalworking fluids are specially formulated fluids used in manufacturing operations such as machining, grinding, drilling, milling, turning, threading, broaching, deep hole drilling, and similar processes.
Main tasks:
To reduce friction between the cutting tool and the workpiece.
Removing heat from the process area.
To reduce tool wear and sticking.
To help remove chips from the processing area.
To provide better surface quality.
To protect workpieces and machine components against corrosion.
Increasing the stability of the production process.
Choosing the right product is critical, especially in high-speed CNC operations, with precise tolerances and difficult-to-machine alloys.
Basic Types of Metalworking Fluids
Water-Mixable Metalworking Fluids
Metalworking fluids, when mixed with water, are widely preferred, especially in high-speed machining operations, due to their high cooling capacity.
Emulsion-type fluids: These are products containing mineral oil that offer high lubrication capabilities.
Semi-synthetic fluids: Provide a balanced performance between cooling and lubrication properties.
Fully synthetic fluids: Formulations that contain little or no mineral oil. They are preferred in applications where cleanliness, high cooling capability, and long fluid life are important.
In modern formulations, low foaming tendency, high biostability, operator comfort, and long tank life are becoming increasingly important.
Pure Cutting Oils
Pure cutting oils are metalworking oils that are used directly without being mixed with water.
Especially;
Threading
Broaching
Deep hole drilling
Heavy turning
Heavy milling
Honing
Grinding
Processing of hard steel, stainless steel, and titanium.
It is used in operations with high lubrication requirements, such as those mentioned above.
High-quality pure cutting oils, thanks to their appropriate viscosity and high-pressure additives, help control tool wear by forming a durable oil film between the cutting tool and the workpiece.
How to Choose the Right Metalworking Fluid?
Metalworking fluid selection should not be based solely on product price. The most appropriate solution should be determined by evaluating the entire process.
Key factors to consider when choosing a product:
Type of metal being processed
Type of operation
Cutting speed and feed rate values
Tool materials used
Machine and filtration system
Water quality and water hardness
Desired surface quality
Corrosion protection
Foam control
Operator compatibility
Tank life and fluid management
Aluminum, carbon steel, stainless steel, titanium, and high-alloy materials have different lubrication and cooling requirements. Therefore, selecting the right product requires technical evaluation and field experience.
Why is concentration control important?
In water-miscible metalworking fluids, the correct concentration is one of the key parameters for system performance.
Low concentration;
It can increase the risk of corrosion.
It can reduce lubrication performance.
It can accelerate microbiological spoilage.
It can reduce tool life.
Extremely high concentrations, however;
It can increase product consumption.
It can cause foaming problems.
It can create residue on the workpiece.
It can negatively affect operator comfort.
Therefore, regular concentration measurements with a refractometer and the correct application of the refractometer factor for the product being used are necessary.
pH and Liquid Quality Monitoring
Maintaining the performance of metalworking fluids requires monitoring not only of concentration but also of pH and overall fluid condition.
As part of periodic inspections;
Concentration
pH value
Scent and appearance
Tramp fat level
Bacterial and fungal formation
Foam tendency
Corrosion condition
Filtration performance
They should be evaluated regularly.
Proper fluid management can extend tank lifespan and prevent unplanned fluid changes.
The Importance of Technical Service in Metalworking Fluids
In metalworking fluids, true performance isn't achieved simply by purchasing the right product. It requires correct on-site application, regular monitoring, and control of process parameters.
GataMerk technical support services include:
Selecting the appropriate product for the application.
Initial filling and system preparation.
Concentration control
pH monitoring
Fluid condition analysis
Tank cleaning and system hygiene.
Laboratory analyses
Problem solving and process optimization
Periodic field visits
Technical training and fluid management
We provide technical support to production processes with services such as these.
Longer Tool Life and Lower Total Cost
The true cost of metalworking fluids is not just determined by the price per liter.
Factors affecting the total process cost include:
Team consumption
Production speed
Scrap rate
Surface quality
Machine shutdowns
Tank change frequency
Cleaning costs
Fluid intake
It is located there.
By selecting the right products and managing fluids effectively, it is possible to reduce the total production cost per unit part, increase process reliability, and improve production continuity.
