The use of coolant for water well drill bits

Drill coolant plays a vital role in the drilling process by reducing the cutting temperature, lubricating the tool and workpiece, flushing away chips, improving machining accuracy and efficiency, and extending tool life. It is vital to use the coolant correctly. The following are detailed instructions on how to use drill coolant:

1. Type of coolant:

Water-based coolant (emulsion): It is the most commonly used type of coolant, made by mixing water and oil in a certain proportion. It has good cooling and lubricating properties, and is suitable for the processing of most metal materials.
Oil-based coolant (cutting oil): the main component is mineral oil or synthetic oil, with excellent lubricating properties and anti-rust properties, suitable for difficult-to-machine materials or high-precision machining.
Synthetic coolant: made of chemical compounds, with excellent cooling performance, lubricating performance and anti-rust performance, suitable for the processing of various materials, especially for high-speed cutting and precision machining.
Micro Quantity Lubrication (MQL): A very small amount of lubricant is sprayed into the cutting area in the form of mist, which has the advantages of environmental protection and economy, and is suitable for some specific machining occasions. 2.

2. Coolant supply method:

External cooling: The coolant is sprayed to the outside of the drill bit and the workpiece, which is the most commonly used cooling method.
Internal cooling: Coolant is delivered to the cutting area through channels inside the drill, especially for deep hole drilling.
Immersion: The workpiece is immersed in the coolant, which is suitable for some special machining occasions. 3.

3. Precautions for using coolant:

Choose the right coolant: Select the right coolant according to the workpiece material, machining requirements and tool type.
Ensure the flow rate and pressure of the coolant: sufficient flow rate and pressure can effectively cool the tool and workpiece, and flush away chips.
Adjust the position and angle of the nozzle: so that the coolant is accurately sprayed into the cutting area to achieve the best cooling effect. 4.

4. Use of coolant under different machining conditions:

Ordinary drilling: External cooling is generally used.
Deep hole drilling: internal cooling is recommended.
High-speed cutting: It is recommended to use synthetic coolant or micro-lubrication to effectively reduce the cutting temperature.

Processing of difficult-to-machine materials: it is recommended to use oil-based or synthetic coolant, and select the appropriate additives according to the specific material.
