YH3MK9380?技术特点：Technical characteristics:
1.一次装夹可将气门盘外圆与锥面、圆弧、盘端面及倒角等型面磨削成型。
2.CBN砂轮高速磨削气门型面，加工效率高，尺寸*性好。
3.机床采用五轴数控、两轴联动，可实现数控插补法磨削和插补法修整砂轮。
4.通过数控插补法修整陶瓷CBN砂轮，工件磨削面轮廓控制灵活、准确。砂轮寿命很高。
5.头架和砂轮架采用高精度静动*承，具有高刚性、高精度和长寿命。
6.采用西门子数控系统和MARPOSS内置式动平衡系统，具有防碰撞和消空程功能，安全性、可靠性高。可实现全自动循环磨削气门。
1. A fixture can grind for forming the valve outer circle and cone, arc, disc face and chamfer type surface.
2.High speed CBN wheel grind valves surface with high processing efficiency and good size consistency.
3. Using five - axis CNC and two axes linkage, can realize the NC interpolation method and interpolation method of grinding wheel dressing.
4. By NC interpolation dressing ceramic CBN grinding wheel, the work piece’s grinding surface profile control is flexible, accurate, and the grinding wheel life is long.
5. The head rack and grinding wheel rack adopts hydrostatic bearing with high precision, high rigidity, and long life.
6 . Adopts Siemens system and built-in MARPOSS dynamic balance system, with anti-collision and elimination process function, high safety, high reliability. This can realize full automatic circular grinding valves.
