锥管螺纹连接具有:不需要任何填料,靠螺纹的变形即可保证所需要的紧密性;端面有余量时,可用轴向位移补偿直径误差的优点。因此,在机车车辆制造业中大量使用着锥管螺纹连接。但是,加工锥管螺纹的螺纹环规是由各量具刃具厂供应的,往往由于规格不全而影响了产品的气密性。我厂在JN105型电火花机床上(该机床原设计用于加工M10～M105圆柱形螺纹环规),用加工锥管环规的螺纹电极成功地加工了各种规格的锥管环规。这种锥管环规经生产使用,性能良好。加工环规的规范为ZG1/8″～ZG3″。JN105型电火花机床的构造、
Conical pipe thread connection has: Does not require any filler, by the deformation of the thread to ensure the required tightness; End with margin, the axial displacement can be used to compensate for the advantages of diameter error. Therefore, taper pipe thread connections are widely used in the rolling stock manufacturing industry. However, the taper pipe thread taper ring gauge by the cutting tool factory supplies, often due to incomplete specifications and affect the product’s airtightness. I plant in the JN105-type EDM machine (the machine was originally designed for processing M10 ~ M105 cylindrical thread ring gauge), with tapered pipe ring thread electrode successfully processed a variety of cone ring. This cone ring ring production by the use of good performance. The machining ring gauge specification is ZG1 / 8 “~ ZG3”. JN105-type EDM machine structure,
