Techni-Grind has installed its sixth Walter high specification CNC tool and cutter grinder to increase capacity levels – a Helitronic Vision 400L with integrated robot handling and wheel changer..

The Vision 400L joins the company’s existing portfolio of Walter tool grinders and tool measuring machines that have been progressively installed. Now, with the new machine meaning that two of the company’s Visions are equipped with robot loader and pallet-held tools, these automation devices “are key to our often non-stop 24-hour running which, of course, contributes greatly to the production efficiencies we attain”, says Managing Director David Higham.


The ISO 9002-accredited company is an approved Tier One supplier to BAE Systems, whose site at nearby Salmesbury is visited daily by Techni-Grind to ensure a planned programme of regrinds is maintained. The company also services sites at Brough and Barrow-in-Furness as part of BAE’s Supplier Excellence Programme.

In 2014 BAE recognised Techni-Grind’s outstanding contribution to this cost-saving initiative by including the company in a team that achieved a silver award in BAE Systems’ global 2014 Chairman’s Award for Innovation competition.  The award is made annually to BAE Systems’ employees and partners throughout the world who have shown ‘outstanding behaviour, innovation or determination’ to improve efficiency and drive down costs.

This success is in no small way attributable to the Walter tool manufacturing technologies, says David Higham, who adds that the cost reductions for BAE are being made on the regrinding of a range of rotary tools:  “We are continually and consistently processing batches of tooling – HSS and carbide end mills and slot drills included – to very high and guaranteed standards for BAE Systems,” he says.  “The ongoing process is made even more challenging due to the highly technical nature of the tools, typically incorporating features like cam relief clearances, unequal index of flutes and constantly varying core diameters. The machining of these complex geometries is overcome by the expert programming technology of our Walter tool grinders.  We fully utilise the machines’ Tool Studio software, in particular in conjunction with the Helicheck Basic tool measuring machine which we use to pre-measure each tool before regrinding to ensure we produce perfectly blended radii without any reductions on shank diameter.”

“We are known for our quality service, competitive prices and on-time delivery,” David Higham concludes. “The industry is forever changing but through continual improvement via, for example, capital investment, we aim to be the number one choice for our customers, both now and in the future.”
