When PCB drilling and milling, what is the temperature variation range of granite elements?

Granite elements have become increasingly popular in the design and construction of PCB drilling and milling machines. This is due to their ability to withstand the high temperatures generated during the machining process without losing their structural integrity. The use of granite elements in PCB drilling and milling machines enhances the accuracy, precision and speed of the process resulting in high quality end products.

The temperature variation range of granite elements used in PCB drilling and milling machines is dependent on several factors. These factors include the type of granite used, the thickness of the granite element, the drilling or milling speed, and the depth and size of the hole being machined.

Typically, granite has a low coefficient of thermal expansion, which means that it will resist deformation and damage caused by high temperatures. In addition, granite has a high thermal capacity, which allows it to absorb heat and maintain a consistent temperature. This makes it an ideal material for use in PCB drilling and milling machines, where high temperatures are generated during the machining process.

Most granite elements used in PCB drilling and milling machines have a temperature variation range of between 20℃ to 80℃. However, this range can vary depending on the type of granite used. For instance, black granite, which has a higher thermal capacity, can withstand higher temperatures compared to lighter shades of granite.

In addition to temperature variation range, the thickness of the granite element is also an important factor to consider. Thicker granite elements are better able to absorb heat and maintain a steady temperature during the machining process. This ensures that the accuracy and precision of the PCB drilling and milling machine is maintained even after prolonged use.

The drilling or milling speed is also a critical factor to consider when using granite elements in PCB drilling and milling machines. High drilling or milling speeds generate more heat, which can cause damage to the granite element. Therefore, it is important to regulate the speed of the machine to ensure that the temperature variation range of the granite element is maintained.

In conclusion, the use of granite elements has revolutionized the PCB drilling and milling process. They are durable and able to withstand high temperatures without suffering damage. The temperature variation range of granite elements used in PCB drilling and milling machines is between 20℃ to 80℃, depending on the thickness and type of granite used. With this information, engineers and technicians can choose the right granite element for their PCB drilling and milling machines to optimize performance and achieve high-quality end products。
