Semi-Synthetic Soluble Cutting Fluid for Metalworking
A reliable semi-synthetic soluble cutting fluid needs to provide stable cooling, lubrication, corrosion protection, and consistent machining performance. The DEPA.800, DEPA.810, and DEPA.820 series are designed for different metalworking requirements, covering general machining, titanium and high-alloy materials, as well as chlorine-free applications.
All three products can support common machining processes such as grinding, turning, milling, boring, drilling, reaming, and tapping. However, each grade has a different performance focus.
DEPA.800 – General-Purpose High-Performance Cutting Fluid
DEPA.800 is a fully efficient semi-synthetic soluble cutting fluid designed for broad metalworking applications.
It provides good lubricity, VHP performance, resistance to deterioration, and protection for non-ferrous metals. In addition, the stable chemical system helps maintain reliable performance even in hard-water areas.
The product is suitable for:
- Ferrous metals
- Non-ferrous metals
- Ceramics
- Glass
Typical machining processes include:
- Grinding
- Turning
- Milling
- Boring
- Drilling
- Reaming
- Tapping
The working fluid appears milky white and semi-transparent, while the pH value of a 5% aqueous solution is approximately 9.0.
DEPA.800 is also suitable for machining aluminum-alloy automotive engine components such as cylinder blocks and cylinder heads.
DEPA.810 – For Titanium and High-Alloy Materials
DEPA.810 is specifically designed for cutting lubrication and cooling of titanium and titanium-alloy materials.
The product offers good lubricity, VHP performance, and antimicrobial properties. Therefore, it is suitable for machining environments where both lubrication and fluid stability are important.
Typical compatible materials include:
- Ferrous metals
- Stainless steel
- Die-cast aluminum
- Other non-ferrous metals
The product supports grinding, turning, milling, boring, drilling, reaming, and tapping.
Its working fluid is milky white and semi-transparent, with a 5% solution pH of approximately 8.8.
For manufacturers processing titanium or demanding alloy materials, DEPA.810 provides a more targeted option than a general-purpose fluid.
DEPA.820 – Chlorine-Free Semi-Synthetic Cutting Fluid
DEPA.820 is a chlorine-free semi-synthetic soluble cutting fluid designed with biological stability in mind.
Its formulation helps control deterioration of the working fluid even under relatively low-pH conditions.
In addition, DEPA.820 provides strong corrosion inhibition for:
- Die-cast aluminum
- Copper alloys
Other compatible materials include ferrous metals, stainless steel, copper, and other non-ferrous metals.
Like the other two products, it supports:
- Grinding
- Turning
- Milling
- Boring
- Drilling
- Reaming
- Tapping
The working fluid is milky white and semi-transparent, and the pH of a 5% aqueous solution is approximately 8.8.
How to Choose Between DEPA.800, 810 and 820
| Product | Main Positioning | 5% pH | Key Application Focus |
|---|---|---|---|
| DEPA.800 | General-purpose machining | 9.0 | Broad material compatibility and hard-water stability |
| DEPA.810 | Titanium and high-alloy machining | 8.8 | Lubrication, cooling and antimicrobial performance |
| DEPA.820 | Chlorine-free machining fluid | 8.8 | Biological stability and corrosion protection |
In simple terms, choose DEPA.800 when you need a versatile fluid for different materials and machining processes.
Choose DEPA.810 when titanium, high-alloy materials, or more demanding lubrication requirements are involved.
Choose DEPA.820 when a chlorine-free system and strong corrosion protection for die-cast aluminum or copper alloys are priorities.
Why Choose the DEPA Semi-Synthetic Cutting Fluid Series?
The DEPA series provides different options while maintaining a common focus on stable metalworking performance.
Key advantages include:
- Good lubrication
- Effective cooling
- Corrosion protection
- Broad machining compatibility
- Support for ferrous and non-ferrous materials
- Options for titanium and alloy machining
- Chlorine-free product option
For manufacturers looking for a reliable semi-synthetic soluble cutting fluid, DEPA.800, DEPA.810, and DEPA.820 offer flexible solutions for different machining conditions.
To select the most suitable grade, consider your workpiece material, machining method, water quality, processing load, and corrosion-protection requirements.
