Appendix A
(Specification)
Vertical special bed boring head model screening method
【This specification specifies the model screening method for vertical grain mill boring heads. The model screening method for vertical grain mill boring heads (for simplified testing) shall comply with the provisions of this appendix. The model screening method for the boring heads of various purposes may also be different from the provisions of this specification. 42 Model representation method
performance type is composed of wave Pei involved sound Ning letter and tensile teaching letter, and its representation method is as follows: [.T
improvement sequence number
second parameter, mm
personal parameter, mm
characteristic code
category code [production type fine boring head
1\" symbol is not indicated when there is no internal narrowness, and no book frame when there is internal consultation. 2 "" is an A number bzxZ.net
the main number of the front head is expressed by 110 of its flange diameter, A 4 Second production parameter
The first main number of the head is expressed as 1/10 of the nominal diameter of the main shaft end. If the main shaft of the lithium head has a pin hole, it is expressed by the number of chain holes. 45 Characteristic code
When the head has other special features in addition to the general performance, the pinyin of the standard is used to represent the most important individual performance in a model. In a few special cases, two waiting can be represented.

When the product is to be selected, the structure will be greatly improved, and the product must be renewed or retained and identified, the original model can be followed by the Chinese phonetic letters A, B, C... (the letter "" and "heart" are not allowed to use A7 boring head number examples
Bag head number examples:
a) The flange diameter is 250mm, the spindle head diameter is 110mm, and the general use pin head. Its model is LT25×11, b) The flange diameter is 200mm, the spindle head is 4V7:24 universal clock head, its model is TW20×40. ) The flange diameter is 320mm, the spindle head is 4 No. Mushiwei hole, and it is a centrally installed universal head, its model is LIw×32×4,
