Scraping and rolling machine is a new type of high efficiency machine tool which can replace the deep hole drilling and boring machine. It is suitable for processing cylindrical deep hole workpieces, various mechanical hydraulic cylinders, cylindrical through-hole blind holes and step holes. Deep hole honing machine deep hole drilling machines are general, special and refitted by ordinary lathe. In order to facilitate cooling and chip removal, the layout of deep hole drilling machines is horizontal, and the main parameter of deep hole drilling machine is the maximum drilling depth. The machine tool is mainly used for boring and rolling processing. The machine tool adopts the boring process of the workpiece not moving and the boring cutter rotating. The front row chips are used in boring. The boring method can be either push boring or pull boring. There are oil feeding at the end of boring bar and chip removal at the head of the bed. Rolling can be divided into front rolling and back stretching rolling. The application of SRB high speed scraping boring rolling head from Germany or South Korea can efficiently process oil cylinder. The traditional process of boring and grinding oil cylinder is changed, and the production efficiency is 5-6 times of that of traditional technology. The application of this machine tool will bring an epoch-making revolution in oil cylinder production. The cutting and rolling speed of oil cylinder produced by cold drawn pipe can reach 1 m / min, and that of oil cylinder produced by hot-rolled pipe can reach 0. 3 M / min, one molding.
The lathe bed is made of high-quality cast iron and has strong rigidity. The spindle is driven by 60kW AC servo motor with wide speed range and large torque. The feed system is driven by 11kw AC servo motor and driven by ∮ 80 ball screw. It can meet the needs of various deep hole processing technologies. The head frame is tight, and the workpiece is jacked with hydraulic device. The electric system can be controlled centrally from abroad, TFT color touch screen LCD, windows operating platform is safe and reliable. The machine tool is equipped with automatic chip removal machine, comb magnetic separator, bag pressure filter (function: filtering impurities, etc.), iron chips are automatically collected into the scrap box, and the coolant is precisely filtered. It is suitable for mass production or small batch single piece production in production. Guide system of scraping and rolling tool. Before drilling into the workpiece, the deep hole drill relies on the tool guide to ensure the accurate position of the cutter head, and the guide sleeve is close to the end face of the workpiece. Quartz glass honing this series of deep hole boring machines can select the following working forms according to the conditions of the workpiece: 1. Workpiece rotation, tool rotation and reciprocating feed motion; 2. Workpiece rotation and tool non rotation, only reciprocating feed motion; 3. Workpiece does not rotate, tool rotation and reciprocating feed
