10、1998 Jig bushes and accessories Introduction This Japanese Industrial Standard is made based on IS0 4247, Jig bushes and accessories for drilling purposes- Dimensions, first edited in 1977, and IS0 4248, Jig bushes- Definitions and nomenclature, first edited in 1978, without any changing to the tech
11、nical details of the corresponding International Standards for the corresponding clauses (2 Definitions, 3 Names of bushes and accessories and types of bushes, 4 Tolerances, and 5 Shapes and dimensions), and the standard details not provided in the corresponding Interna- tional Standards (Dimension
12、series J Type) are supplemented. 1 Scope This Japanese Industrial Standard specifies press-fit bushes and renewable bushes to be used as guide for drill and reamer, liners to guide them (hereafter referred to as “bushes” as generic term) and their accessories (tenon and locking screw). Remarks : Cor
13、responding International Standards are as follows : IS0 4247: 1977 Jig bushes and accessories for drilling purposes- Dimen- sions IS0 4248: 1978 Jig bushes - Definitions and nomenclature Definitions The definitions of main terms used in this Standard shall be as follows : press-fit bush A bush press
14、ed directly into the appropriate hole in the jig-plate and used for guiding a drill or reamer in cases where it is not anticipated that replacement of the bush will be necessary or where the dimensions between the centers of adjacent hoies are such as to preclude the use of renewable bushes and line
15、rs. These may be classified to their design as headed or headless. renewable bush A renewable bush intended for insertion in a liner and used for guiding a drill or reamer. There are two types of renewable bushes, round type, which has no way to fix, and notch type, which is able to fix. liner A bus
