Boring Blank Adapter

Boring Blank Adaptor is exclusively designed to manufacture the special tools and special applications. The blank adaptor is manufactured with specifications regarding HSK 63-80-250 DIN 69893 Form A. Unlike other adaptors, the cone and flange part of the boring blank are hardened and grinded. Thus making the overall tooling operation more efficient and productive. Boring Blank Adaptors are used in special applications where the tooling and machining of the workpiece are difficult to carry out the boring works. All holders of Boring Blank Adaptors are made of Tool steel material.

Specific, low warpage hardened materials are specially used in the manufacturing of these adaptors. Surface Hardened HRC 58~60 is the tool material that is used as the core material of the blank adaptor. Boring Blank Adaptor HSK 63-80-250 DIN 69893 delivers great machining performance on the hardening depth of 0.8mm~0.9mm. These adaptors develop a taper angle tolerance < AT 3 according to DIN 2080. Boring blank adaptors are suitable for tooling the workpiece of surface roughness Ra < 0.4 ┬Ám and the tensile strength in the core of minimum 800 N/mm2 after DIN. All functional surfaces are fine machined.
