BB60 Portable Line Boring Machine is a compact, versatile and powerful line boring machine in the first
class of the world. Easy to set up, designed to get tough jobs done relatively easy. Easily configured for
difficult machining applications.
• Bearing mount assembly can be designed according to customers' needs. Adjustable mechanism ensure
the coaxality of the boring bar, machine-body and bearing mount assembly.
• Durable all closed aluminum alloy machine-body, gear oil is used to lubricate and cooling the gears.
• Advanced worm gear reducer, high efficiency and high torque output, cutting ability 8mm in the radius.
• The slotless structure avoids the bending deformation of the boring bar due to the machining stress.
• Feed stroke can be easily changed.
• Easy to operate with the remote controller. The electric control box is separated from the machine-body,
avoiding the loosening of electric lines caused by the vibration during the machining process.

 Aluminum alloy shell machinebody, weight only 13Kg.
• The boring bar through the machine-body to ensure the coaxiality of the machine-body and the boring
bar. The machine-body can be installed at any position of the boring bar. This feature allows BB50 can
be setup in a tight space.
• The patented feed mechanism is a reliable and durable structure with almost no fault. Variable speed
feed mechanism can acheive forward feed, reverse feed, and manual feed function
• Powerful AC 2.2Kw drive motor, variable speed control by a frequency converter. General motor, stable,
easy maintenance. The connection between the motor and the Machine-body is convenient to
disassemble, and the suitable motor can be replaced according to the local conditions. 380V
three-phase power.
