Key Functions of Cutting Oil

01/

Lubrication
Creates a strong lubricating film between the cutting tool and workpiece to reduce friction, lower cutting forces, and minimize tool wear.

02/

Cooling
Helps transfer heat away from the cutting zone, reducing thermal deformation of both tools and workpieces while improving dimensional accuracy.

03/

Chip Removal
Assists in flushing metal chips away from the cutting area, preventing chip recutting and improving machining stability.

04/

Surface Protection
Protects freshly machined metal surfaces from corrosion and oxidation during production and temporary storage.

05/

Tool Life Extension
Extreme-pressure and anti-wear additives reduce adhesive wear, built-up edge formation, and micro-welding, significantly extending cutting tool service life.

06/

Improved Productivity
Stable lubrication enables higher cutting speeds, smoother machining, and reduced machine downtime, contributing to lower overall manufacturing costs.

Applications

Our cutting oils are engineered to deliver peak performance across a wide spectrum of industrial metalworking operations:

CNC Turning & Milling: Provides consistent cooling and lubrication for high-throughput automated production lines.

Deep-Hole Drilling & Boring: Exceptional chip-flushing capability and high-pressure stability to prevent tool breakage inside deep cavities.

Threading & Tapping: Formulated with active EP additives to ensure clean, sharp thread profiles and prevent galling.

Broaching & Gear Shaping: Heavy-duty neat oils designed to withstand extreme mechanical loads, ensuring perfect surface finishes on complex gears.

High-Speed Grinding: Ultra-low foaming synthetic fluids that quickly remove heat, preventing thermal cracking and burns on ground surfaces.

Compatible Metals

Our product line features dedicated formulas optimized for specific metallurgy to eliminate stain risks and optimize tool contact:

Ferrous Metals:

Carbon Steel, Alloy Steel, Tool Steel, Cast Iron, and Heavy-duty Stainless Steel (304/316).

Non-Ferrous Metals:

FAQ

Q: What is the minimum order quantity (MOQ) for bulk cutting oil?

A: Our standard MOQ for stock formulations is 1 pallet (typically 4 drums of 200L or 1 IBC tote). For custom OEM formulations or private labeling, the MOQ generally starts from 3,000 Liters.

Q: Can you provide free samples for factory testing?

A: Yes, we provide complimentary 1L to 5L samples for industrial testing and qualification. Buyers only need to cover the express shipping cost, which is fully refundable upon your first commercial bulk order.

Q: How do I determine the correct dilution ratio for water-soluble cutting oils?

A: For general turning and milling, a 5% to 7% concentration (1:20 to 1:15 ratio with water) is recommended. For severe operations like tapping or deep drilling, increase the concentration to 8% to 12%. For light grinding, 3% to 5% is usually sufficient.

Q: Does your cutting oil contain chlorine or sulfur?

A: We offer both chlorinated/sulfurized oils for heavy-duty extreme pressure applications, as well as chlorine-free and active sulfur-free eco-formulations designed specifically for sensitive aerospace alloys and non-ferrous metals like copper.

Q: How do I prevent my water-soluble cutting fluid from smelling bad?

A: Foul odors are caused by bacteria thriving in anaerobic conditions (usually under a layer of tramp oil when the machine sits idle). Using our bio-stable semi-synthetic fluids, regularly removing tramp oil with a skimmer, and maintaining the correct fluid concentration (above 5%) will prevent odor issues.

Q: Are your cutting oils safe for machining aluminum? Will they cause staining?

A: We have a dedicated line of non-staining cutting fluids formulated specifically for aluminum and copper alloys. They maintain a balanced pH to ensure zero oxidation or staining on sensitive metal surfaces.

Q: What is the typical shelf life of your cutting oils?

A: Sealed in original packaging and stored indoors away from direct sunlight and freezing temperatures, our neat cutting oils have a shelf life of 24 months, and our water-soluble concentrates have a shelf life of 12 to 18 months.

Q: Do you provide GHS-compliant Material Safety Data Sheets (MSDS)?

A: Absolutely. We provide comprehensive, legally compliant MSDS/SDS sheets in English (and other requested languages) detailing chemical composition, safety handling, and transport regulations.

Q: How does hard water affect your water-soluble fluids?

A: Hard water contains high levels of calcium and magnesium, which can cause standard emulsions to split or foam. Our fluids incorporate advanced water hardeners and stabilizers that remain perfectly stable in water hardness up to 400 ppm.

Q: What is the lead time for a 20ft container order?

A: For our standard stock products, the lead time is 7–10 days. For custom OEM orders involving packaging design and custom blending, lead time is typically 15–21 days from deposit approval.
