British people are automating production with VOLLMER technology 2024-05-31

The city of Doncaster is located in the English county of South Yorkshire in the heart of Great Britain, and is home to the tool manufacturer Unilap. The company was founded in 1974 by Darrell Hughes as "South Yorkshire Saw & Tool Co" (Systco). Back then, it was just a small company for sharpening saw blades and selling accessories. Today, his son Carl Hughes runs the company, which was renamed Systco-Unilap in 1992, and now employs 22 people and manufactures more than 5000 product lines for the British market. As an expert in woodworking and metalworking, Unilap develops customised tools for the automotive industry, the aerospace industry and industries that process composite materials.

Unilap has been relying on VOLLMER for more than 40 years

Unilap's portfolio includes both carbide-tipped circular saws and rotary tools made of carbide and ultra-hard cutting materials such as PCD (polycrystalline diamond). The company is achieving an annual growth of 25 per cent with its routers, profile tools, drills and circular saws. To strengthen this development in existing as well as new markets, Unilap has expanded its production capacities with VOLLMER technology. In 2022, the English tool manufacturer commissioned three more VOLLMER machines in addition to the eight it already has. "We have relied on VOLLMER for more than 40 years and love the brand for its quality, innovative strength and reliability. That's why we are proud that we now have eleven VOLLMER machines in operation," says Carl Hughes. "The new VGrind 260 in particular represents a new approach for us – to take automation in the production of rotary tools to a new level."

VGrind 260 has initiated a paradigm shift

The VGrind 260 tool grinding machine delivered in October 2022 has initiated a paradigm shift at Unilap. Previously, carbide tools were produced semi-automatically on two machines, with an employee having to continuously change the tools. With the automated VGrind 260 and the HC 4 chain magazine, Unilap can now produce its rotary tools around the clock in an unmanned operation. In addition, the VGrind 260 with proven VOLLMER kinematics and double spindle enables high-precision multi level machining, which has significantly increased the quality and service lives of Unilap tools.

"In the past, we had to painstakingly plan tool machining and assign it to the respective machines in order to minimise the changing of grinding wheels and collet chucks as well as reprogramming," says Bob Young, General Manager at Unilap. "Now, we can load the chain magazine with tools of different diameters and the VGrind simply keeps going – this has enabled us to reduce the machining time per tool by more than 80 per cent."

Unilap is expanding its capacities with the CHX 840 and QXD 250

With the VOLLMER CHX 840 grinding machine for carbide-tipped circular saws, which arrived in Doncaster in April 2022, Unilap has expanded its capacities in the automated production of carbide-tipped circular saws. Thanks to the HS loading system, unmanned operation is possible, which relieves the strain on existing VOLLMER machines when it comes to production and maintenance. The QXD 250 erosion machine complements the previous VOLLMER QXD 200, which the tool manufacturer has now been using for ten years for the machining of PCD tools. Equipped with the HC 5 tool storage, the QXD 250 can hold a total of 28 tools weighing up to 25 kilograms, and feed them to the erosion machine in 24/7 shifts.

"The QXD 250 with the innovative Vpulse EDM erosion generator increases our cutting speeds by up to 40 per cent and, at the same time, ensures a significantly improved surface quality of around 0.1 μRa," says Bob Young. "Thanks to the intuitive ExLevel PRO software, we can also program our tools 50 per cent faster than before. Overall, the time saving is between 70 and 80 per cent if we include the efficiencies in programming, set-up and touching."

The British grinding market remains attractive for VOLLMER

Unilap's most recent investments in sharpening machines made by VOLLMER also show that the British market will remain attractive for the Swabian machine manufacturer even after Brexit. VOLLMER has been represented in Great Britain with its own subsidiary since 1980. VOLLMER UK is based in Nottingham, a city located around 80 kilometres south of Doncaster in the triangle formed by the economic hubs of Manchester, Sheffield and Birmingham.

"Exports are the foundation of our company's success, which is why VOLLMER is represented in 15 countries around the world with their own subsidiaries – we generate around 80 per cent of our turnover abroad," says Andreas Böhm, CEO of the VOLLMER Group. “The English tool manufacturer Unilap is a prime example of how customers around the world have remained loyal to us for decades, even when economic hurdles such as Brexit pose new challenges for partnerships.”
