BTA is drilling the problem can not be ignored. In fact, most drilling encountered problem is poor chip removal (especially when machining low carbon steel workpiece), and regardless of the use of tungsten carbide drills were unable to avoid this problem. External processing plant are often used way of auxiliary coolant injection chip, but this method is processed only in the depth of the hole is less than the diameter of the cutting parameters and reducing conditions effective. In addition, the diameter of the drill bit must be selected to match the proper coolant type, flow and pressure.
