Sales of XYZ Machine Tools’ range of machine tools, particularly its ProtoTRAK controlled mills and lathes, are showing strong growth across Europe, with sales now representing 13% of company turnover. From the turn of the year sales have steadily increased thanks to renewed manufacturing confidence, particularly in the Czech Republic, Slovakia, the Netherlands and Belgium. Overall sales in 2021 to date are already 33% higher than the previous year, and are predicted to double by the year-end.

September saw 10 machines despatched to customers in Belgium, Czech Republic, Germany, Sweden and Spain. While travel to visit these customers has been restricted, the export team at XYZ has remained active. In addition, a Norwegian dealer has just come on board, further extending the distribution network for XYZ machines.

With a new development in the hexagonal chuck series from Hainbuch, the German clamping device manufacturer says it is taking precision to a new level. The new Toplus Premium Chuck introduces a host of additional advantages.

Hainbuch’s portfolio of chucks has always been very precise and, once chucks alignment is complete, runout is near to zero for repeat clamping. If the various chuck heads are then changed, runout is usually between 3 to 7 μm without alignment.

With the new Toplus Premium Chuck, Hainbuch guarantees a runout of ≤5 μm without alignment, regardless of which clamping head is used. Until now, this was only possible with an expensive hydraulic expansion or a diaphragm chuck. These systems have limitations entailed by their design. In many cases, runout of ≤10 μm is perfectly sufficient. However, components or machining processes that demand a runout of ≤5 μm are increasingly commonplace within the industry. By utilising the new Toplus Premium Chuck with the associated premium clamping heads and, by clamping against the workpiece stop, this level of accuracy is always achieved. As a result, manufacturers no longer have to lose time making alignments for small batch sizes.

To reduce set-up times, improve machine utilisation and reduce costs, a robot is often used to load the workpieces in the machine. This strategy can become a problem if the clamping stroke is too small. With the Toplus Premium Chuck combined with a clamping head, the stroke is increased to make loading easier, even if the robot works somewhat imprecisely. In addition, the Toplus Premium Chuck is very robust and not as sensitive as some other clamping devices. Any slight contact with the workpiece during loading has no effect on the chuck and the process remains stable. The chuck is also sealed against contamination and vibration.

Now available in the UK from Industrial Tooling Corporation (ITC) is the Mega synchro tapping chuck from Big Kaiser. This new tapping chuck has a special function built-in to compensate for synchronisation errors that may occur during rigid tapping.

The new product line incorporates more than 60 body types and 193 tap holders. This diverse portfolio enables the end user to select the perfect combination between the fixture and the tap holder, providing the ideal cantilever length for any machine and processing scenario.

Big Kaiser’s Mega synchro tapping chuck compensates for synchronisation errors with any type of tap as the system minimises thrust load to both the tap and workpiece, thus improving thread quality and extending tap life. The chuck has a proprietary feature that intercepts the tap-to-spindle distance when using a tapping cycle to reduce cutting forces. This feature is complemented by a body and tap holder that are fixed with a drive key in the rotation direction – as well as the square of the tap – to guarantee stability and process security. Process security is further improved by a coolant system that delivers coolant through the tool as well as around the periphery of the tool simultaneously.

ITC’s Andy Boyles says: “There are many companies now producing a ‘synchro’ type tapping head, but the Big Kaiser Mega has a unique difference. Due to its design, it’s possible to interchange the tap holders to different sizes, and it is available in several different lengths. Furthermore, the system permits through-coolant Synchro tapping in very deep holes with a very stable set up.”
