Portable boring machines

Portable boring machines Mainly used for on-site processing pipeline bore, concentric hole spacing, hole large equipment and hole end of the processing and repair, suitable for excavators, cranes, cranes and other construction machinery, ships rudder shaft hole , stern shaft hole, pipe flanges, a variety of large frame hinge hole and so on.

Features:
1. Portable boring bar of the rotary device, compact, high power to weight ratio;
2. Boring bar made of high strength steel, the overall quenching, after many times to stress aging, polished chrome plated, high hardness, rigidity, and not deformed;
3. Spindle with worm gear box, small size, transmission ratio, the worm uses a special metal imports, lubricity, wear resistance, long life;
4. Various forms of support fixtures to meet the needs of different work environment, support are: one-arm support, the word support, T-support, cross support, center support, floor support, self-aligning support, etc. ;
5. Bearing support proprietary Anti-Shake technology, high accuracy and rigidity;
6. Car tool holder can end automatically before and after the tool path, feed rate is adjustable and detachable, easy installation and removal;
7. Well-designed bearing end plates can be adjusted in any direction and tilt to compensate for any inaccuracies. ; Aaaaa 8. High precision machining, surface roughness Ra1.6;
9. Axial feed box automatic feed, with a third gear transmission, the rough, finishing out the most suitable feed rate, and with positive and negative, and manual feed conversion block;
