Connecting Rod Boring Machine, BR650, AZ

The BR650 is a connecting-rod boring and grinding machine featuring planetary grinding adjustable during the operation. It is engineered to combine boring and grinding in one setup, built on a rigid cast-iron base. The boring spindle speed is variable via an electronic variator with digital readouts. The con-rod holding square offers variable longitudinal speed with a reversal limit switch, plus crosswise movement for easy centering. A micrometric grinding-wheel eccentricity device refines finish quality. A coolant system with electric pump is included.

Advantages & Features:

• Adjustable planetary grinding during the process.
• Variable boring spindle speed with electronic variator and digital indications.
• Rod-holding square with variable longitudinal speed and reversal limit switch.
