Valve seats boring machine with high availability meets the requirements of boring, reaming and cutting machining for high accuracy valve guides and valve seats. Light boring head of patent-based design is equipped with triple air flotation device, self-centering system and combined motor shaft. Designed specially for repairing small-sized engine and compound-cylinder engine used on motorcycle and automobile. Meet the requirements of high precision machining for valve guides with a small diameter of 3mm.

@With distinctive characteristics of this new type machines that can save 30% cutting force during machining process. Ensure the angle accuracy of compound angle tool within a range of ± 0.5.
@Machining capacity: 16mm/0.63" - 50mm/1.97".
@Modernized design of standard machine body to agree with the improved rigidity. Dynamic and static features are optimized by computer to provide the most advanced machining process.
@Improved lighting system.
@Pneumatic clamping of table bars.
@Fully integrated spindle motor: Infinitely variable spindle speed, 100 to 1200 RPM, with sensorless Vector Flux Control in open loop (extremely broad torque ratings from lowest RPM. ).
@Lightweight workhead: Built-in spindle motor and triple air-float automatic centering system. Minimal workhead inertia and maximal floatation for unmatched centering sensitivity.
@High-quality three color saturation painting.
