Digital display Valve seat boring machine TX90DRO


Digital display Valve seat boring machine TX90DRO
High precision valve seat and valve guide cutting machine especially designed for multi-valve cylinder heads. Patented workhead with triple air-float patented centering system and built-in spindle motor.



◆Featuring the new generation of valve seat boring.Provides more than a 30% decrease of cutting forces during Machining. Angular accuracy within ±0.5 degree guaranteed on multi-angle cutter.
◆Machining capacity from 0.55″/14 mm to 3.6 “/90 mm.
◆Modern modular machine bed design for improved rigidity. Computer enhanced static and dynamic characteristics provide The latest in machining technology.
◆New improved lighting system.
◆New table bars with pnevmatic locking.
◆Fully integrated spindle motor, Infinitely variable speed 100 to 1200 RPM, with sensorless Vector Flux Control. Forward and reverse
directions. Extremely broad torque ratings from lowest RPM with constant torque spindle rotation. Digital RPM read-out for accurate speed setting.
◆Patented Workhead with triple Air-Float Automatic Centering System and built-in spindle motor. Greatly reduces the number of free-floating parts during the centering sequence.Results in minimal work-head inertia and maximal floatation for unmatched centering sensitivity.
◆High quality smooth, 3 tone paint work.
