Deep hole cutter for processing power plant tube sheet
Power plant tube sheets (steam turbines, boiler tube sheets) are generally made of high-strength low-alloy steel (such as 20MaMo, etc.), the diameter of the tube sheet is large (φ1600～φ2500mm), and its processing characteristics are many holes (2000 per tube plate). Porous), small (φ15 to φ20 mm), deep (200 to 300 mm), the roughness of the hole is Rα 3.2 to 6.4, and the tolerance level of the hole is IT7 to IT8. When the parts are assembled, the copper pipe of several meters long can be smoothly passed through the two ends of the tube plate. Therefore, the pitch tolerance of the hole on the tube plate is required to be ±0.5mm, and the straightness of the hole is required to be 0.15/300mm. The degree is not more than 0.05mm. For the processing of such parts, industrial developed countries generally use BTA in horizontal CNC drilling machines.
