Portable digging machine boring

Tianjin, Taiyuan casting machinery factory www.tjtangkongji.com, engineering machinery manufacturing and maintenance of large enterprises, with professional R & D institutions, advanced testing equipment and production processing equipment. Key products include construction machinery, maintenance equipment and domestic imports of various styles of construction machinery cylinder maintenance and spare parts. Excavators boring machine. Versatile: different configurations can be boring straight hole and tapered bore, equipped with numerical control system, can process any shape bore. A variety of installation: can be equipped with ten to Flexible: forward and reverse boring and feed, the feed rate is adjustable, can be converted automatically or manually feed. Wide scope: choose different lengths of screw, boring bar and cutting head. Support word, the word support, floor support or center support, self-aligning bearing and mounting bracket to ensure that equipment for quick installation. Two drive forms: can be equipped with electric or hydraulic drive portable boring machine use: large equipment for boring through holes. Compact: all components optimized design, compact dimensions. Powerful: the power head with constant torque boring machine is also frequently used internal boring machinery components, precision instruments can also give high-precision bore machining. Such positioning means better tools, including: no less than three of the same positioning column, set First, the technical parameters: 1, motor power: 1.5KW, high-speed 147 r / min, low speed 47 rev / min. 2, Boring range: diameter 60 mm-200 mm. 3, the boring bar length: 1.5m. 4, the boring bar diameter: 50mm. 5, Material: 45 #. Processing, 6, processing: the tune of hardened hard chrome plated surface. 7, cutting feed rate: 0.14㎜ / rev. 8, maximum cutting capacity: unilateral 1.5mm. 9, the working stroke: 270㎜. Top core bit holder and positioning, these positioning means cooperate with each other before they can play securely fastened. Spud is the positioning of the sleeve and the support with the bearing components, and in the positioning of the sleeve must have several through holes, number of holes of not less than three, the holes are in line with the positioning column with every through holes have to be positioned perpendicular to the center position of the sleeve. Nail shape for the positioning of the core, which is working with the end into a cone shape, and the other end is fixed to, at this end are generally equipped with a top hat, the working end of the core to be positioned tightly against the internal positioning of the column.
