Portable Line Boring Machine for Contruction

Machine Performance:Compared with similar products,BB50 portable boring machine has the following obvious 
advantages:
1. New design of the mainbody structure, aluminum alloy shell, weight only 13Kg.
2. The boring bar through the mainbody to ensure the coaxial of the mainbody and the 
boring bar. The mainbody can be installed at any position of the boring bar and can be 
installed in a narrow space.
3. The patented feed mechanism is a reliable and durable structure with almost no fault. 
Stepless speed feed mechanism can acheive forward feed, reverse feed, and manual feed function.
4. Powerful AC 2.2Kw drive motor, stepless speed control by frequency 
converter.General motor, stable, easy maintenance. The connection between the 
motor and the mainbody is convenient to disassemble, and the suitable motor can be 
replaced according to the local conditions. Optional power supply :220V single phase 
or 380V three-phase power.
5. Bearing mount assembly can be designed according to needs. Adjustable mechanism 
ensure the coaxality of boring bar, mainbody and bearing mount assembly.
6. Durable all closed aluminum alloy mainbody, gear oil is used to lubricate and coolingthe gears.
7. Advanced worm gear reducer, high efficiency and high torque output, cutting ability8mm in the radius.
8. The slotless structure avoids the bending deformation of the boring bar due to the 
machining stress.9. Feed stroke can be easily changed.10. Easy to operate with the remote handle handle. The electric control box is separated 
from the mainbody, avoiding the loosening of electric lines caused by the vibration the 
machining proce
