该产品选用碳化钨材料(超硬合金)精密加工而成。硬度高达HRA90以上,抗弯度高达2300N/mm以上。公司采用专用设备进行精密磨削加工和表面处理,使内孔粗糙度达到Ra0.1,两端R处粗糙度高达Ra0.025。两端出入线口曲率半径科学设计,保证过线顺畅自然,与红宝石线嘴相比,因采用整体材料加工,线嘴孔内无台阶,改善了易弯堵塞的现象。
优点:具有极高的钢性和硬度,耐冲击。
This product is made by the precision machining with the tungsten carbide materials (superhard alloy). The hardness reached over HRA90 degree while the anti-bending degree reached over 2300N/mm. We do the precision grindingsurface treatment to achieve Ra0.1 of the bore roughnessthe Ra0.025 of the R place of both ends. There is a scientific curvature radius design in the both entrance. This design can ensure a smooth transit of the thread. Due to the overall materials processing,no elevation in the bore, the phenomenon of easy-bendingplugging has been improved comparing with the ruby nozzle.
Advantages: high hardness, rigidimpact resistance.
