RH Series Rust‑Proof Emulsified Oils – Product Overview
RH Series – High‑Performance Rust‑Proof Emulsified Oils
Product Series Type
Emulsified oils (water‑miscible, oil‑based concentrates)
Main Functions
Rust prevention, emulsification, lubrication, cooling, cleaning
Application Range
Turning, grinding, milling, drilling, broaching, and general machining of ferrous metals, copper alloys, and alloy steels
Series Description
The RH Series is a range of premium rust‑proof emulsified oils formulated with deeply refined mineral base oils and carefully selected functional additives. These products form stable emulsions with water, delivering excellent rust protection, cooling, and cleaning performance for a variety of machining operations. With two distinct grades, the series covers both general‑purpose ferrous and copper alloy machining, as well as more demanding alloy steel applications requiring enhanced extreme‑pressure lubrication.
Recommended Applications
The RH Series is suitable for CNC lathes, grinding machines, milling machines, drilling machines, and broaching equipment. It is widely used in automotive parts, general engineering, and precision machining workshops. The recommended working concentration is 2–10%, which can be adjusted based on the specific operation and material requirements.

Core Advantages of RH Series
Superior Rust Prevention
Provides reliable in‑process corrosion protection for ferrous metals, copper alloys, and alloy steels, helping maintain workpiece quality between processing stages.
Stable Emulsion & Good Lubricity
Forms a consistent, stable emulsion that ensures effective lubrication and cooling across a wide range of machining operations, from light grinding to heavy broaching.
Flexible Concentration Range
With a recommended concentration of 2–10%, the RH Series can be easily adapted to different processes – lower for grinding, higher for heavy cutting and broaching.
Application Purpose
The RH Series is engineered to improve machining efficiency and part quality through effective rust protection, cooling, and lubricity. These emulsified oils are particularly suited to workshops that process a mix of ferrous metals and copper alloys, where in‑process rust prevention is critical.
Typical applications include automotive parts, general machinery, bearing components, and copper alloy fittings. For higher‑strength alloy steel parts or heavy‑duty broaching, RH3210 is the recommended choice.
Machining Application Reference
Turning
Provides effective cooling and rust protection for continuous turning operations on steel, cast iron, and copper alloys.
Milling
Good lubricity and chip flushing help reduce friction and improve surface finish in milling applications.
Grinding
Excellent cooling and cleaning properties prevent wheel loading and ensure a fine surface finish on ferrous and non‑ferrous components.
Broaching
RH3210 is specifically recommended for broaching alloy steels, where its extreme‑pressure additives reduce tool wear and improve surface quality.
Why Choose RH Series?
Designed for workshops that require reliable rust protection, stable emulsions, and versatile machining performance across ferrous and copper‑based materials.
Effective In‑Process Rust Protection
Protects workpieces between machining stages, reducing rework and scrappage due to surface corrosion.
Versatile Material Compatibility
Choose RH3110 for general ferrous and copper alloys, or RH3210 for tougher alloy steel applications – all with one reliable emulsion system.
Adjustable Concentration for Flexibility
The 2–10% concentration range allows fine‑tuning for grinding (lower) through to heavy broaching (higher) without changing product families.
Technical Selection Support
Our team can help you select the correct grade and dilution ratio based on your materials, equipment, and productivity goals.
Product Selection Support
To help you choose between RH3110 and RH3210, please provide details such as workpiece material (ferrous, copper alloy, alloy steel), machining process (grinding, turning, broaching, etc.), machine type, current fluid in use, and any issues like rust, poor surface finish, or tool wear.
Technical Data Sheets (TDS), Safety Data Sheets (SDS), packaging information, and samples are available upon request. Customised concentration recommendations can also be provided.
Frequently Asked Questions
Common questions about RH Series selection, application, and performance.
Which RH grade should I choose for my operation?
Choose RH3110 for general turning, milling, and grinding of ferrous metals and copper alloys. Choose RH3210 if you are machining alloy steels, performing heavy broaching, or need enhanced extreme‑pressure lubrication.
Can RH Series be used on copper alloys without staining?
Yes. RH3110 is specifically formulated to protect copper alloys without causing discolouration. RH3210 can also be used on copper alloys, but compatibility testing is recommended for sensitive applications.
What concentration should I use for grinding vs. broaching?
For grinding, start at the lower end (2–4%). For turning and milling, use 4–8%. For heavy broaching and demanding cutting, use 8–10%. Always adjust based on water hardness and actual performance.
Are technical documents and samples available?
Yes. We provide TDS, SDS, packaging information, and sample support. Contact our sales or technical team for assistance.
