Description
All HSK tooling manufacturers have been challenged by the extremely tight tolerances the HSK standard demands. To achieve such a high degree of precision, manufacturers must use special inspection technology with extremely fine resolution. Gages and instruments have to be recalibrated to measure in the 0.000010" range. Additionally, the HSK manufacturer must use special high-resolution sensors and processing devices and locate its final grinding operation in a temperature-stable environment.
We provide all HSK tooling standards, which describe HSK Shanks and HSK Spindle Receivers. They are: DIN 69063, DIN 69893, ISO 12164-1 and ISO 12164-2. Totally over 20 HSK tooling standards were published so far.
Originating in Germany in the later 1980s, the HSK family of standard toolholders was developed to meet the needs of ever increasing spindle speeds. Steep-taper tooling, using CAT V-Flange, SK and BT toolholders, had begun to show its limitations at spindle speeds in excess of 8,000 rpm. Already widely accepted in Europe, HSK is still relatively new in the United States. American automotive and aerospace manufacturers have been the early adopters of the technology.
