Cheltenham-based Delapena Group — a world leader in grinding and honing (www.delapena.co.uk) — this month celebrates its 10th anniversary under the ownership of David Arthur. Reporting a seven-figure order book, it continues to grow and has set its sights on doubling its turnover by 2020.

Mr Arthur saved the business from financial disaster a decade ago and has invested heavily in it since then. It is now a successful group — specialising in surface finishing in the bore or on the shaft — with a portfolio of electronically controlled honing and grinding machines plus the tooling, fixtures, abrasives and oils to support their operation.
