Professional deep hole drilling has been widely used in the mold industry, and it is also a common processing technology. We all know that in the process of using deep hole processing, we need to solve many problems, including how to select different coolant delivery methods. The vertical processing centers we see in our daily life are generally self flowing, low-pressure through shaft and high-pressure through shaft There are three different types of cooling systems.
In the process of deep hole machining, the bit will generate heat due to friction, which will "heat treat" the workpiece around the hole, thus producing work hardening. This heat heats the workpiece. When the coolant reaches the heated material, it is quenched by the coolant. In the following series of retreating process, the drill bit meets the hardened material, so that the drill bit is worn or damaged.
In order to achieve successful deep hole machining, it is particularly important to make the coolant reach the top of the bit. We need to find a way to take away the heat and discharge the chips. The through shaft cooling system provides us with a good solution
