Recut your engine blocks with honmaksan cylinder borer. It is a machine with a rugged body dampening almost all vibrational effects during machining. It is well designed with its boring spindle perfectly aligned to make any liner as perfect as an OEM product. Its unique features includes (but not limited to) self retraction of spindle head at the end of a stroke with the cutting tool stopping at a preset point without damaging the machined surface. Thanks to the inclusion of the frequency inverter drives to the machine as they enable adjustments of various (spindle, table & head) speeds while maintining high torque and stability.
