机夹不重磨浅孔钻是近几年新发展起来的先进孔加工刀具。本文根据最近的国外资料,较全面地描述了这种刀具的主要结构特征和使用条件,可供刀具设计制造部门及工艺师们参考。一、不重磨浅孔钻的使用范围和优点人们只要对孔加工领域的情况稍加分析即可发现,对于直径φ在16mm以上的孔,绝大多数都属于浅孔加工范围,即孔深l≤2.5D。因而不重磨浅孔钻具有宽广的使用范围。一般说来直径在16～60mm以内是它的常规加工领域。在这个加工范围内,可用它在实心坯料上直接钻孔,不需要予制孔或中心孔,而
Machine folder is not reworked shallow hole drilling is the newly developed advanced hole processing tool in recent years. Based on the recent foreign materials, this paper describes the main structural features and conditions of use of this tool in a comprehensive way, which can be used for reference by tool design and manufacturing departments and craftsmen. First, do not rebuild the use of shallow hole drilling range and advantages People as long as the situation in the field of drilling a little analysis can be found for the diameter of φ 16mm above the hole, the vast majority belong to the shallow hole processing range, namely the hole depth l≤2.5D. Thus do not rebuild a shallow hole drill has a wide range of use. In general, the diameter of 16 ~ 60mm or less is its conventional processing. In this range of processing, it can be used in the solid billet direct drilling, without pre-made holes or holes, and
