When machining metals like aluminum, copper, or brass, excessive heat generation is a common challenge. This heat can damage the end mill or the workpiece, affecting precision and overall productivity. A cutting fluid system is an effective solution to this problem. In this article, we will explain how the system works and why it is essential for CNC routing.
Wattsan M1 series machines
Wattsan M1 series CNC routers are designed for precision machining of metals such as aluminum, copper, and brass. These machines can be equipped with a cutting fluid system to enhance their efficiency.
The M1 series features a reinforced frame with increased wall thickness of 10 to 12 mm, ensuring stability and vibration resistance during operation. Additionally, the Z-axis height is extended to 300 mm, allowing for the processing of larger workpieces. These enhancements were developed based on feedback from Wattsan dealers and customers, ensuring that the machine meets the practical needs of users.
The cutting fluid system operates through a specialized nozzle that delivers liquid—typically water—into the working area. The liquid then drains into a dedicated runoff system, preventing flooding of the guides and helical rack. The fluid is filtered and pumped back to the nozzle for continuous circulation. This system enables efficient machining of aluminum, including mold production.
Functions of the cutting fluid system
The cutting fluid system serves multiple critical functions:
- Reduces friction: it minimizes friction between the end mill and the workpiece, reducing heat generation.
- Prevents overheating: by keeping the cutting area cool, it protects the tool and material from thermal damage.
- Enhances processing quality: stable temperatures result in cleaner cuts and more precise results.
- Extends tool life: reduced friction and heat help prevent premature wear of the end mill.
- Prevents corrosion: the system helps avoid corrosion on both the tool and the material during machining.
Types of cutting fluid systems
Cutting fluid systems can operate with water or oil-based coolants. Water-based systems offer an excellent balance of affordability, availability, and effectiveness across a variety of materials.
With the Wattsan M1 1313 and its integrated cutting fluid system, you can process materials like aluminum, copper, brass, and even acrylic. While some users opt to build their own DIY systems, a factory-installed solution is more reliable. This is because key design elements, like liquid drainage, are professionally engineered for optimal efficiency.
This machine features a working area of 300 x 300 mm and a Z-axis access height of 300 mm. Custom models can be designed upon request to accommodate specific production needs. Machine’s bed is constructed from welded steel with 10 to 12 mm thick walls and undergoes a heat treatment process to ensure stable spindle operation without vibrations.
All Wattsan CNC routers incorporate components from trusted brands, such as Teyu, S&A, Hiwin, Shimpo, and Siemens. For instance, the M1 1313 model is equipped with Hiwin linear guides known for their precision and durability, ensuring more accurate and reliable performance. The Z-axis also features Hiwin guides, which provide additional stability and precision during operations.
Furthermore, the base for the kinematic system is milled at the factory using a robotic complex, ensuring flawless geometry and accurate, error-free operation.
Tips for using the cutting fluid system
Control of the coolant flow during machining is straightforward using M-codes:
- M08 – activates the fluid as a jet.
- M07 – activates the fluid as a mist.
- M09 – turns off the fluid system.
These codes make it easy to adapt the machine for processing different materials, such as switching from metal to wood.
Conclusion
A cutting fluid system significantly expands the capabilities of your CNC router.
With a reliable machine like the Wattsan M1 1313, you can efficiently process metals like aluminum and brass, ensuring high productivity and consistent quality. Investing in a professionally designed cutting fluid system not only enhances processing performance but also extends the lifespan of your equipment and tools.
