    Gewefa UK will be introducing its substantially enlarged ‘Hydro-Pin’ range of single  point boring bar toolholders at the MACH 2020 exhibition while also providing the opportunity for visitors to view and discuss a range of new products available from its partners.

    Apart from its own brand toolholders, Gewefa will be featuring equipment from EWS, OTT-Jakob, Pibomulti, Nann, Rineck and for the first time, products from the Fahrion Precision Centro P Premium range of collet chucks.

    There are now a number of new variants of the hydraulic Hydro-Pin toolholder to accommodate a wide selection of boring bar shanks, many with their own location configurations.  Features common to all include substantially reduced setting times – by as much as 75% – and an up to 50% increase in cutter life due to the more secure, vibration-free grip.

    In all formats, a paramount feature of the design is the need to eliminate run out with a guaranteed centre height at the insert tip being essential for successful high precision machining.  There is also guaranteed repeatability when changing like-for-like bars and a simple, fool proof fitting process.

    Being a hydraulic chuck, Hydro-Pin removes the need for reduction sleeves when securing the bar, guaranteeing anti-vibration damping and reducing the opportunities for inaccuracy and bar deflection during the boring process.  

    The most common location format in proprietary systems features a ground angle on the back end (of the bar) locating against a stop pin at the base of the toolholder.  This ensures precise central positioning and orientation with the bar then locked into the hydraulic chuck.  Gewefa also supplies more bespoke variants such as required for the Coromant Easi-Fix boring bar shank which features a spring plunger mounted in the toolholder body.  

    Gewefa offers the hydraulic chuck for ARNO, System Dieterle, DTS/HOBE/MAS/SUMITOMO/SANDVIK/ SIMTEK and VARGUS screw orientation options along with all other systems. 

    Also on the Gewefa stand will be exhibits from all six of Gewefa’s partners:

    EWS, the driven tool experts, are introducing a new intelligent tool monitoring technique called CyberCon4 which monitors a range of processes within the tool in order to optimise its performance.  

    German machine tool accessory specialist OTT-Jakob will be featuring its new all-in-one rotary union with an innovative monitoring function. The 2KA-ME union combines proven twin channel technology for the hydraulic release and integrated media transfer with state-of-the-art clamping condition sensor technology. Also featured from OTT-Jakob will be the highly acclaimed Power Check spindle monitoring system.

    Swiss speeder and angle head specialist Pibomulti has a further addition to its Rainbow range of angle heads, this being a head able to clamp up to a Ø12mm tool shank via a Gewefa hydraulic clamping system.

    Heat shrink clamping machine expert Rineck will be featuring toolholders and cutters from its range while collet specialist Nann will show two latest developments; a new MSK manually operated collet chuck and a spindle unit range for use with draw-back collets, dead length collets and expanding collets.

    Finally, the newest partner Fahrion will be featuring products from the Fahrion Precision Centro P Premium range of collet chucks, the Ultra Power Chucks, Dynamic Performance Chucks and Mini Precision Chucks.

    The standard Centro P collet chuck system is widely available with features integral to all Fahrion systems including the tried-and-tested Fahrion ‘Protect’ coating on the collets.  However, features of the Premium specialist programme create new application areas and opportunities.
