Schunk Develops Extended Profile Hydraulic Chuck for Moldmaking Industry
The HSK-A long, slim hydraulic chuck
was designed for mold and die making, tool manufacturing and other applications
where the surfaces to be cut may be out of the reach of shorter shank chucks.
Designed for applications such as deep cavities or other "confined" or deeply
contour surfaces, the HSK-A is available to handle tool shanks from 6mm to 20mm,
with gage lengths ranging from 80mm to 200mm.
"The HSK-A is an addition to SCHUNK's extensive line of TENDO Hydraulic Chucks providing precise run-out accuracy, high clamping forces and torque transmission, and the capability to run accurately and safely at extreme cutting speeds. Clamping forces up to 23,000 lbs. or more assure safety at all speeds -over 15,000 RPM with special balancing," a company spokesperson stated.
"TENDO Hydraulic Chucks employ a unique and powerful shank-holding system. An internal piston pressurizes hydraulic fluid into a cavity surrounding a steel sleeve. The high pressure uniformly forces the sleeve around a cutting tool shank. Cutting tools are held with great concentricity. The enormous clamping pressure displaces oil or grease into TENDO grooves in the sleeve. As a result, clamping areas remain almost dry and high torque transmission is guaranteed at all running speeds. The hydraulic system also absorbs vibrations inherent in the cutting or grinding processes. The results are very high T.I.R. accuracy and repeatability < 3 microns (0.000 12"); tool life extended up to four times; greatly improved surface quality of machined parts," explained the spokesperson.
TENDO Hydraulic Chucks offer toolholding solutions for a variety of manufacturing processes. Chuck models are available for: high-speed and fine milling; heavy-duty milling; wood machining; HSC-Parallel-stroke milling; internal grinding; boring and chamfering; precision reaming; precision tool grinding. With TENDO slotted, coolant-proof intermediate sleeves, different shank diameters can be handled with the same chuck for additional application versatility and tooling cost savings. All TENDO Hydraulic Chucks are completely closed systems that operate free of dirt, coolants, lubricants, and chips to assure low maintenance and high operating lifetime.
