TECHNOLOGICAL COMPARISON

Thread Connection vs. Pokolm DuoPlug® Connection

Where the difference is:

Pokolm Thread Connection – our high-performance standard	Our Patented DuoPlug® System – the perfect enhancement
Pokolm Thread Connection	Pokolm-DuoPlug®= Shrink and Screw
Possible materials for arbors or adaptors: steel, dense antivibration material, or solid carbide	Possible material for adaptors: solid carbide
This standard thread connection is produced with the best tolerances possible using the latest technology. We maximize the efficiency of our Pokolm thread connections by optimizing our design of arbors, adaptors, and milling cutter bodies.	Our Pokolm DuoPlug® system offers optimum rigidity and extremely high precision and concentricity. As a supplement to conventional thread connections, the retention and supporting forces between cutting tool and adaptor act along the entire surface of the shrink fit and a large part of the shrink thread. For more information, please see the assembling and dismantling instructions for our DuoPlug® system in the ”Operation Data” chapter. The fact is:  DuoPlug® perfects the thread connection by means of greatly increased retention forces, resulting in the highest possible precision for extremely slim dimensions.
Performance no undercut, thus avoiding a rated break-point extremely precise fit zone and extremely precise end face better tensile strength and heat resistance because of the special materials and extra-hard coating for hundreds of tool changes optimized chamfers on arbors and adaptors	Performance maximum precision and concentricity optimum stability absolutely backflash-free class of fits between adaptor and body because of shrink connection extremely precise and consistent connection greatly increased retention forces compared to conventional thread connection better tensile strength and heat resistance because of the special materials and     extra-hard coating
Your Advantages ideal application area increased process reliability applicable for all roughing and finishing operations better fatigue strength and red hardness lower tool costs because of longer tool life great increase in stability because of larger end faces	Your Advantages longer tool life  absolutely minimal vibrations with long overhangs renders top precision in finishing operations increased availability of tool system and increased process reliability improved performance in roughing operations better fatigue strength and red hardness
Ideal Applications low-cost standard equipment for milling operations in shallow and medium-deep cavities especially for deep machining applications   without 90° walls	Ideal Applications for maximum precision in finishing operations roughing and finishing applications with long overhangs ideal for applications on 90° walls because of extremely slim arbor/adaptor system
