Reamer/Coupling System maximizes repeatability/flexibility.
May 15, 2009 -
Enabling flexible high-speed reaming, RHM modular reaming system includes KST coupling system providing simultaneous taper-face contact, resulting in less than 3 microns runout. Reamer heads, available in sizes from 0.7874-1.6535 in. dia, are offered in straight-flute style for blind holes or helical flute style for reaming thru-holes. Thru-the-tool coolant is standard. Ground and lapped lead angles maximize tool life. Radial or axial clamping systems are available.
Kennametal RHM(TM) Modular Reamers/KST(TM) Coupling Systems Provide Excellent Repeatability and Flexibility
(LATROBE, PA) - The new RHM modular reaming system from Kennametal brings enhanced flexibility to high-speed reaming. Using high-precision, interchangeable reamer heads with respective steel bodies, the RHM modular reaming system reduces tool setup time and machine downtime.
The heart of the system is the KST (Kennametal Short Taper) coupling system. Similar to the KMTM system, the KST system provides simultaneous taper-face contact, resulting in less than three microns runout and a very rigid union. Two drive flats on the reamer shank and in the tool body foster symmetrical torque transmission for higher speeds and feeds.
Two clamping options are available. The radial clamping system makes for fast head changes inside the machine and provides quick and easy clamping. The axial clamping system is economical, provides low actuating torque due to a differentially pitched clamping screw, and consists of fewer parts. Both systems require minimal training to implement.
Reamer heads are available in either straight-flute style for blind holes or helical flute style for reaming thru-holes and can be applied to both clamping versions. Thru-the-tool coolant is standard for both styles. Very unequal flute spacing reduces harmonics, providing a straighter hole and consistent diameters. Ground and lapped lead angles facilitate longer tool life and higher surface and hole quality. The reamers come tipped in either carbide or cermet, utilizing the best grades and coatings developed by Kennametal experts.
Reamer heads are available in stock sizes ranging from 20 to 42 mm (0.7874 to 1.6535 inch) diameter and as custom solution tailored to customers diameter and tolerance requirements. Tool bodies come in straight shank style, HSK style, and SIF steerable adaptors style available as 3 and 5 times the diameter length versions each covering a diameter range of reamer heads.
"The new RHM Series Modular Reaming System will result in machined holes with more accurate diameters, better surface finishes, and better overall quality achieved in less time," according to Thilo Mueller, Kennametal cutting tools product manager.
