Using the right cutting fluid can protect machinery even when operating at high speeds.
Available from brands like Petro-Canada and Castrol, cutting fluids act as a coolant and lubricant during metal machining. They effectively reduce heat and friction, preventing damage to the workpiece and reducing tool wear.
Here we look at some advantages of choosing the correct cutting fluid.
Lower costs
The lubrication and cooling cutting fluids supply is critical to reducing operating costs. Selecting the right type of fluid can ensure equipment works at top performance, reducing energy use and cost.
The right fluid choice also fights corrosion, heat damage and excessive wear. This results in fewer tool and machine part replacements and reduces mechanical downtime while repairs are carried out. Additionally, fewer workpieces require discarding due to damage.
Prevents rust and contamination
Cutting fluids can protect wrought and cast iron, but also iron alloys like cabin steel and stainless steel against rust. Iron-related machine parts subjected to high temperatures, oxygen and moisture are at risk of iron oxide, also known as rust, but the correct cutting fluid will have an appropriate pH level (over nine) that helps fight corrosive forces in ferrous metal.
Bronze, brass, aluminium and other non-ferrous metals require a lower pH level (four to nine). The right fluid will also stop bacteria forming in machinery in areas where used cutting fluid accumulates.
Clears metal chips and other debris
The remains of machining work are referred to as metal chips. This unwanted debris must be flushed away, and the essential chip-removal process must keep in step with chip formation or mechanical breakdown occur.
Too many metal cuttings and tramp oil (used oil mixed with used coolant) is problematic. The debris accumulates and contaminates the new cutting fluid. The right cutting fluid will effectively flush chips and unwanted used fluids to the sump for extraction.
Reduces metal on metal contact
Finally, the correct cutting fluid decreases metal-on-metal contact, minimising friction. It will form a robust layer of fluid between the machine tool and workpiece, thereby mitigating damage.
Commonly used soluble cutting fluids create a cushion that guarantees smoother surfaces for high-quality workpieces and reduces premature wearing on the tool.
To sum up, selecting the right cutting fluid can have major user benefits – so care and consideration is essential when ordering a suitable product.
