Linsheng Electromechanical Co , Ltd., Technical Points Of Deep Hole Drill
Gun drill is an effective deep hole machining tool with a wide range of processing, from deep processing of glass fiber, Teflon and other plastics to high strength alloys such as P20 and Inconel. In deep hole machining where tolerances and surface roughness are critical, the gun drill ensures dimensional accuracy, positional accuracy and straightness of the hole.
Linsheng Electrical Co , Ltd. said: In order to achieve satisfactory results when machining guns deep holes, you must be proficient in the performance of the gun drilling system (including tools, machine tools, fixtures, accessories, workpieces, control units, coolants and operating procedures). ). The skill level of the operator is also important. According to the structure of the workpiece and the hardness of the workpiece material and the working conditions and quality requirements of the deep hole machining machine, the appropriate cutting speed, feed rate, tool geometry, carbide grade and coolant parameters can be selected to obtain excellent processing performance. .
Straight groove gun drills are used the most in production. According to the diameter of the gun drill and through the inner cooling holes of the transmission part, the shank and the cutter head, the gun drill can be made into two types, integral and welded. The coolant is ejected from the small holes in the flank. The gun drill can have one or two circular cooling holes, or a single waist hole
Linsheng Electrical Co , Ltd. added: The standard gun drill can process holes with a hole diameter of 1.5mm to 76.2mm, and the drilling depth can reach 100 times of the diameter. The specially ordered gun drill can machine deep holes with a hole diameter of 152.4mm and a depth of 5080mm. Although the feed per revolution of the gun drill is lower, the feed per minute is larger than the twist drill (the feed per minute is equal to the feed per revolution multiplied by the tool or workpiece speed).
