HSK TOOLS Tooling system for turning on multi-task machines

Highly accurate and rigid HSK-T type tooling system for use on multi-task machines.
HSK-T System (ICTM standard)
HSK-T is a new HSK system designed for turning on multi-task machines that are compatible with HSK-A type (ISO standard: ISO12164-1:2001). It was jointly developed by a consortium of Japanese manufacturers and is now used worldwide as the ICTM standard. The new HSK system was published as an ISO standard under the denomination of HSK-T type in 2008. (ISO12164-3:2008)
HSK TOOLS
Highly accurate cutting edge positioning
The HSK-T type has a closer tolerance between the spindle key and tool holder keyway than the HSK-A type. This results in higher cutting edge positional accuracies. For milling, the conventional HSK-A type tools can be still used.

Compatible with both multi-task machines and machining centers

Straight type tools suitable for use on multi-task machines
Avoid workpiece interference with improved tool accessibility.
IMAGE By tilting the machines B spindle (main axis of the tool) at 45 deg. interference between the spindle, holder, workpiece and chuck can be avoided.
Improve centerline height by positioning the cutting edge at the center of the spindle.
IMAGE Increased stability and accuracy can be achieved because the cutting edge centerline height is not affected by the gap between the spindle and the key.

New single-action double clamp series
The double clamp mechanism offers high rigidity, accuracy, reliability that ensures secure insert clamping. Therefore making it suitable for turning of difficult to machine materials such as stainless and heat resistant alloys.
