A big deep hole boring machine with a boring diameter of 1000mm and a maximum boring depth of 16000mm produced by our company was delivered to the Russian customer last month. The picture shows our technicians at the customer's installation site. This machine is used for machining pipe mould and other big pipes, not only boring, but also trepanning, so the machine adopts hydrostatic pressure guide way.
There are two process forms during processing for this machine:
a. workpiece rotates, cutting tool reverse rotating and feed;
b. the workpiece rotates and the cutting tool does not rotate but only feeds.
Drilling or boring diameter less than Φ 210, the BTA internal mental chip removal process of oil pressure head supplying cutting fluid, discharging chips and cutting fluid in the inner hole of drilling/boring rod is adopted.
During boring and rolling, the boring rod is provided with cutting fluid to discharge cutting fluid and metal chips forward (at the head of the machine).
During trepanning bigger holes, the process of external chip removal is adopted, the trepanning rod does not rotate and the workpiece rotates. During trepanning smaller holes, adopting the internal chip removal process, both the trepanning rod and workpiece can be rotated. The machine tool is suitable for processing large hydraulic cylinders, high-pressure boiler tubes, pipe molds, wind turbine shafts, ship transmission shafts and nuclear power tubes.
According to the characteristics of trepanning process, the machine tool is designed to be equipped with relevant parts, special cutter rods, cutters and special trepanning parts, so that the machine tool is more suitable for deep hole trepanning process.
Another bigger deep hole boring machine which its maximum drilling diameter Φ 210mm, maximum trepanning diameter Φ 500mm and maximum boring diameter Φ2000mm workpiece with length 16m has also just been installed in the domestic customer’s factory, please find its photos in the follow, in recent years, In recent years, our company has developed some large heavy-duty deep hole drilling and boring machines, and the maximum boring diameter has reached 3000mm.
