Gewefa UK will be majoring on an innovative new high security toolholding concept at MACH 2016

Gewefa UK will be majoring on an innovative new high security toolholding concept at MACH 2016 while using the opportunity to present the latest products from its five specialist partners.

 

The new Gewefa ‘Venturi’ toolholder concept is a universal tool clamping solution that incorporates safety and adjustment features from three of its proven designs plus a unique thro coolant capability.

 

It has been designed primarily for aerospace applications where arduous, precision machining using challenging materials is becoming increasingly commonplace.  By combining the established features of a hydraulic toolholder with ultra-safe Gewefa Securlok clamping, the side accessed precision Radax adjuster and now the coolant feature, Gewefa believes it has created a truly unique combination.

 

Well established features of hydraulic tool clamping include vibration damping and 100% tool shank gripping concentricity.  The proven mechanical fail safe Securlok whistle notch (DIN 1835 Form E) cutter grip design complements the hydraulic features with the side clamping mechanism making it ideal for general and heavy duty milling operations in titanium, composites and ISO S rated materials. 

 

The Radax features permit high precision pre-setting – even on the machine – using an externally accessible worm gear mechanism which is now complemented by the new Venturi cooling.  This offers coolant from two sources - one directed along the tool shank with a second flow via angled jets incorporated into the front of the tool clamping bore.

 

Another ‘first’ at MACH will be the Gewefa single point boring bar toolholder – the ‘HydroPin’. This Gewefa invented toolholder utilises the proven tool grip features of a hydraulic chuck with the added advantage of guaranteeing fixed orientation when positioning the bar.

 

By eliminating the previously accepted method of securing boring bars by fitting an adaptor reduction sleeve into a VDI mechanical boring bar holder the opportunities for inaccuracy and bar deflection during boring operations are now greatly reduced.

 

Gewefa has five specialist partners in the UK and each will be featuring their latest products.

 

Pibomulti will introducing a new economical and energy efficient spindle speeder specifically for quick change, high volume tapping operations offering a halving of cycle times while producing a 90% saving in power consumption.

 

Also from Pibomulti, its micro engineered right angle drilling head is ideal for drilling in difficult-to-access areas (such as edge walls) that are typically found in aerospace, automotive and hydraulic component manufacturing. The unit can operate at up to 12,000rpm in even the most confined spaces and accommodate tools up to 6mm in diameter.

 

EWS, the highly respected manufacturer of driven and static toolholders for CNC lathes has upgraded its quick change Varia modular toolholding system into Varia-VX, offering increased performance for turning and milling processes.

 

Precise, fast and powerful, Varia-VX allows a maximum concentricity through the new three point locking system and triangular drive spigot which has a positive effect regarding high spindle torque. This characteristic is of particular importance where small tool dimensions are being used and also permits use at torques up to 200 Nm.

 

Building on the initial success of its Power Check pull force gauge, OTT-Jakob now offers a mark III version of the unit that provides readings remotely via a handset, enabling the automated checking of the spindle pull-back force.  

 

Preventative maintenance can be carried out quickly and efficiently with the Power Check unit being housed within a nominated pocket in the machines’ tool carousel in readiness for the next spindle pull back reading. 

 

Featured from clamping technology expert Simon Nann GmbH will be a modular quick change MZ manual clamping unit that converts the base unit from a conventional clamping head to a dead length collet system, a draw-back collet or for expanding mandrels.

 

MZ offers versatility being suited to double sided machining or machining of long parts (with a tailstock support).  A simple key movement through 180 degrees converts the base unit from clamped to unclamped.

 

Finally heat shrink clamping specialist Rineck will be introducing a new upgraded induction heating device for undertaking clamping and unclamping of tools in heat shrink toolholders.

 

The vertical ‘elevator’ design permits a compact benchtop installation and the unit features automatic tool cooling for safety and consistency.
Both carbide tools (Ø3 - Ø32) and HSS (Ø6 - Ø32) can be shrunk in the new 10Kw machine with all parameters, shrink times and performance data stored on the machine in its internal database.
