Delapena ‘goes large’ at MACH

April 2016 –

Master of the honing market, Delapena displayed the breadth of its product and service expansion at MACH2016, with demonstrations of its new high volume honing machines, precision grinding machines and abrasives, plus its existing electronically-controlled honing machines and oils.  The Group has grown dramatically since its last appearance at the show, thanks to strategic partnerships, and focused its display this year for the automotive market.

Delapena is now the largest honing machine manufacturer in the UK and the group has extended its provision thanks to strategic partnerships with US manufacturer, Engis and the CUMI corporation adding grinding machines, abrasives and higher volume capability to its existing honing range.  This, it says, justifies its claim to offer complete surface finishing in the bore or on the shaft.

The company’s legacy strength in honing was still very much on show at MACH, with an Engis’ SPM single pass machine in operation, suitable for high accuracies on high volume production runs (circa one million components).  At the other end of the production spectrum, Delapena also demonstrated the ProductionHone Mini, which caters for honing medium volumes of parts.  The high accuracy PrecisionHone was displayed on the stand, with a specific focus on engine turbo finishing.  From its wide range of honing tooling, a representative selection was on show, including a cylinder honing tool, fitted with diamond super abrasives, used for honing automotive cylinder bores.

Precision Grinding was demonstrated, with a Precigrind Rotary Grinder from CUMI, suitable for automotive, aerospace, medical and general engineering applications.   Precision rotary truers and dressing tools were shown as part of this grinding machine display, alongside a range of conventional abrasive grinding wheels and super abrasive tools.   Oils completed the Delapena Group portfolio, with a selection of specialist industrial oils and lubricants being shown.

“Visitors have offered their honing and grinding challenges to us at the show and we have brought together specialist from Delapena, Engis and CUMI to provide specific solutions for their applications,” said managing director, Martin Elliott.  “We have also taken this opportunity to talk with other machine builders at the show to explain how we can complement their products with our machinery and abrasives, which could give their customers the total package.”

Explaining the automotive focus, Martin Elliott commented, “This industry is predicted to grow by 20 per cent over the next four years and Delapena is well aligned to support this with specialist automotive tooling for both honing and grinding.   Five major OEM engine manufacturers visited the stand at MACH to discuss engine honing tooling and grinding products and initial discussions have been very positive.  We will now progress these further, following the show.”

According to Delapena, visitor numbers to its stand were very good, with a high percentage of quality contacts:  “We were delighted with the calibre and potential of the contacts made at the show,” said group chairman, David Arthur.  “We have enjoyed the reaction of visitors, when they see all that Delapena can now deliver and the level of support that we are offering.”
