625LHSK-A63 50mm

625 Extended Barrel CNC Spindle Series

50mm

Integration of the popular HSK-A63 tool holder into the 625S spindle housing delivers constant high speed with ultra-low vibration and improves accuracy and rigidity. The powerful 625LHSK-A63 (50mm) is designed for close workpiece operations and machines with very short z-axis travel. The 625LHSK-A63 (50mm) delivers patented constant governed high speed operation under load up to 0.50 hp / 0.37 kW at 30,000, 40,000 or 50,000 rpm. At these high speeds, tool coatings achieve the required temperatures to extend endmill life saving money as well as accelerating production. Air Turbine Spindles® patented constant governed high-speed operation under load cuts faster and cleaner – speeding up cycle times and achieving major savings. Faster cutting with small end mills and drills, finishing or polishing with super accuracy. High-speed cutting improves finish quality and accuracy with a fast light pass of your tool. No Duty Cycle.

We retrofit any CNC machine to mill at a constant high speed 24/7 – so any CNC can be a high-speed machine. This includes, but isn’t limited to DMG MORI, Haas, Fanuc Robodrill, Doosan, Hermle, Hurco, GROB, Brother Okuma, Makino and Mazak. Easy installation using selectable air feed inlets – choose side inlet NPT / Stop Block or center through shank/tool holder air feed. HSK, CAT, BT, and DIN Toolholder options are available.

Automatically Tool Change on your CNC

Block and Collar on the Automatic Tool Changer Assembly

Automatically load Air Turbine Spindles® in CNC machines with our patented wrap-around Toolchanger Mounting Assembly (TMA). This option allows CNC tool-changers to automatically load/unload our family of high-speed precision spindles using a proprietary collar system and mounting block or ring around the CNC spindle integrated to the right side of the CNC spindle in minutes.

For machines that have an air blast line or coolant channel that can be used to supply sufficient CFM / L/s airflow volume;  Air Turbine Spindles can tool change without the Toolchanger Mounting Assembly. All HSK spindles can be used with center air feed if air supply line has sufficient ID.

Mounting blocks or rings compatible with Haas, Hurco, Doosan, Robodrill, Hardinge, DMG, Brother, Okuma, and all other CNC’s are available. We are accustomed to developing custom solutions for any CNC. A Universal Block can be provided for drilling your CNC screw positions. Installation Kits are available. The TMA block remains on the CNC spindle for normal tool changes, even if not using the Air Turbine Spindles™ as it will not interfere when using the main spindle.

 

TMA Assembly Includes

  1.  Mounting block or ring assembly
  2. Spindle manifold collar with adjustable height connector to block
