From Fig. 1 and Fig. 2, it can be seen that the high-pressure coolant passes through the hydraulic head base supported by the central bracket and the drill sleeve on it and enters the head of the BTA bit through the holes distributed in the drill sleeve. The chips cut by the cutting edge of the head are forced into the drill pipe and discharged backwards to prevent the leakage of the high-pressure coolant lubricant. The indenter base is closely encapsulated with the workpiece and the rear part. Before entering the workpiece, the BTA bit should enter the drill pipe first so that it can get correct orientation and centering. Drilling sleeve has a high accuracy requirement. Generally speaking, it is required to reach F7 level. When drilling quality is high, it should reach G6 level. BTA bit is very long. In order to prevent vibration and deflection of drill pipe, the machine tool uses a number of special damping supports with vibration reduction function. Deep hole processing can be either tool rotation or workpiece rotation, or both rotate in opposite direction. Linear feeding is accomplished by the cutter, depending on whether the drill pipe rotates or not, the structure of drill sleeve and damping support of hydraulic bit base. It’s different. The coaxiality of each support is required to hold the drill pipe precisely and consistently, and the back end of the drill pipe is clamped by a special clamping device on the machine tool. The diameter below? 56 can be clamped by cylinder, and the larger clamp with slotted jacket. With this method, the hole depth can reach 250 *D. This machine tool can also be equipped with drills, broaching and boring tools and deep hole drills with flat or spherical bottom of the hole can be machined. The machining accuracy of BTA deep hole processing tool hole ofWe can reach IT6-9 level. The deviation of center line after processing is related to the machine tool, tool, process method and related cutting parameters. In the process method, generally only the workpiece rotates best, and the workpiece rotates opposite to the drill bit. Secondly, the bit rotation is poor. Compared with BTA solid deep hole drill, the tool used in hole processing is the worst, reaming drill, and broaching boring tool is the best.<\/p>\n\n\n\n

Botek’s BTA bits and reaming drills are of many types, and the number of blades with smaller diameters is less, so only one can be used. The tip of the blade is staggered from the axis, and the guide bar has two pieces. The number of blades and the number of derivatives should gradually increase with the increase of diameter. The layout of the wrong teeth of the blade can vary from one blade to six blades, and the number of derivatives can also increase from two to six blades. The advantages of using guide are as follows: shortening the overhang length and increasing the rigidity of the blade, keeping short overhang and high rigidity at the cutting head when drilling and enlarging deep holes, which can ensure the stability and high accuracy of deep holes. Rigidity improvement restrains vibration, so it is possible to use sharper cutters. Improve the quality and efficiency of processing, adjust the tool outside the production line, adjust accurately and save time. Figure 2 also shows that the guide bars only support the head of the deep hole drill, while the longer part of the drill pipe is supported by damping. If the length L of the unsupported drill pipe is too long, the drill pipe may flutter due to flexion and centrifugal force.We has the recommended value according to the different diameter of drill pipe, and the number of damper supports should be set according to the recommended value.<\/p>\n\n\n\n
