Haimer A63.140.3/16Z.00 Shrink-fit Adapter HSK63A

Product Description

The HAIMER A63.140.3/16Z.00 is a shrink-fit tool holder adapter designed for precision CNC machining applications. It features an HSK63A taper shank interface and accepts tooling with a 0.1875 inch hole diameter. The adapter provides a projection of 3.1496 inches and an overall length of 4.1575 inches, making it suitable for applications requiring extended reach. With a balanced speed rating of 25,000 RPM, this adapter is built for high-speed machining environments. It is installed by CNC machinists and toolroom technicians in milling, boring, and similar metal-removal operations.

This shrink-fit adapter is used in CNC machining centers equipped with HSK63A spindle interfaces. The Basic Series designation indicates a standard-geometry adapter suited to general-purpose high-speed milling and drilling setups. A clamping depth of 0.4724 inches and a nose diameter of 0.3937 inches support secure tool engagement in production environments. It is appropriate for both job-shop and production floor use where consistent tool runout and balance are critical to surface finish and tool life.

Key Features

• HSK63A taper shank for direct spindle interface on compatible machining centers
• 0.1875 inch (3/16 inch) hole diameter for shrink-fit tool retention
• Balanced to 25,000 RPM for high-speed machining applications
• 3.1496 inch projection provides extended reach capability
• 0.4724 inch clamping depth secures tooling firmly within the bore
• No through-coolant, suitable for dry or external coolant delivery setups

Compatibility

Designed for use with HSK63A spindle interfaces on CNC machining centers requiring shrink-fit tool retention with a 0.1875 inch bore diameter.

Installation Notes

Installation and tool changes require a shrink-fit heating and cooling station to thermally expand and contract the bore for tool insertion and removal - do not attempt to press tools in or out mechanically. Power down or lock out the spindle drive before performing any tooling changes. Verify adapter balance rating against the machine spindle specification before operating at elevated RPM. Follow the machine tool manufacturer guidelines and applicable shop safety procedures for high-speed toolholding.
