Coolant is very important to the process of deep hole drilling high-pressure cooling system. Today's advanced deep hole drilling high-pressure cooling system coolant is roughly the same as the way to control the machine spindle or shaft. Careful management of cooling water pressure, filters, temperature and flow is key to optimizing the deep hole drilling process

Coolant pairHigh pressure cooling system for deep hole drillingThe process is crucial, and the coolant of today's advanced deep hole drilling high-pressure cooling system is roughly the same as the way to control the machine spindle or shaft. Careful management of cooling water pressure, filters, temperature and flow is key to optimizing the deep hole drilling process. For this purpose, a programmable flow-based variable speed control function needs to be integrated into the deep hole drill. Make the system have the necessary adjustment capabilities to ensure that the pressure of the coolant system does not exceed the pressure required for effective debris and accurate drilling.

The advanced cooling water transport system for many years is the main shaft straight-through cooling water system, except for the saliva type. Then, the emergence of high-pressure cooling water systems that work at pressures above about 1,000 Pa is particularly effective in the field of cooling water technology, especially most regular processing operations, and the efficiency of chip removal is higher. Drill bit applications (mainly applications using twist drills) are the main driving force for the development of high-pressure cooling water systems. Especially for deep hole drilling applications, the aspect ratio is usually above 1033601.

　　High pressure cooling system for deep hole drillingThe original data equipment manufacturer (such as UNISIG) designed the method of designing the system (such as the system) and the internal control center machine tool structure through the coolant to ensure integration and performance consistency.

However, as the pressure of the cooling water increases, proper filtration and temperature control are required. When considering systems above 1,000psi, in order to prevent pump failure, 20-50 levels of filtration are required. In most cases, high-pressure cooling water systems require coolers to adjust the temperature of the coolant. Most companies stop using these systems, but even in demanding drilling applications, filtration and cooling water alone cannot solve one of the important variables in the use of high-pressure cooling water-flow.

It is usually not known how much coolant their system will transport or need to transport. For example, a typical overflow cooling water system provides a flow rate of about 10gpm to about 40gpm depending on the system. However, as the diameter of the hole becomes larger or deeper, a larger volume is required to dislodge the dandruff during the drilling operation. For example, if a larger gun or BTA tool is used, a 10-12 inch (25.4-30.5cm) diameter orifice would require a coolant flow rate in the range of 50 gallons per minute to 75-350 gallons per minute. Deep diameter holes may only require 2gpm, but the pressure level is much higher. For example, a hole with a diameter of 0.040 inches (1.016mm) may require a coolant pressure of up to 3,000Pa.

In addition, through the feedback of the cooling water pressure and flow rate to the process management itself, the tool can be analyzed to detect system damage. For example, a sudden drop in coolant pressure in an enterprise application research application may result in tool damage. At that moment, you can choose to stop the process and replace the tool. This is particularly useful when drilling holes of smaller diameter. In this case, it is difficult to detect small changes in force due to light drilling loads. But by monitoring the cooling water through the network, the operator can determine the working environment status of the tool and whether the student is removing dandruff. By further optimizing parameters such as transport and speed, the debris in this data situation can be better controlled.
