精确制造 meaning in Chinese

o precision fabrication

Compared with the existing rp methods using high energy density beams , the hpdm method solved the key problems of insufficient dimensional precision and surface quality caused by the step effect and no - supporting , and puts forward a new way to directly manufacture the difficult - to - machining materials parts with short - routine , low - cost and high quality
该技术解决了现有高能束熔积成形技术因无支撑和台阶效应造成的尺寸精度和表面质量不高的瓶颈问题，是难加工材料零件短流程、低成本、高质量无模精确制造的新的有效加工方法。
