it is hard to ensure the require shape and dimension precision of workpiece in the predicting process of sintered nd-fe-b magnet, so it should be shape machined after sintering.
由于在制模和烧结过程中无法保证工件所要求的形状和尺寸精度,烧结后必须进行成型加工,磨削和电火花线切割加工是目前常用的加工方法。
asindustry and economy developing, the shape and dimension precision of sheetmetal part must need higher demand.
随着工业和经济的发展,板材成形件的形状和尺寸精度的要求日益提高。
with the die structure, some conventional stamping processes can be improved and the shape and dimension precision of some formed parts can be better guaranteed.
介绍了一种便于刃磨的曲面沖切模,利用该模具结构可以改进某些传统的沖压工艺过程,并更好的保证某些成形零件的形状和尺寸精。
