kerf unleashes ‘the beast’ at AJS Profiles

When it comes to heavy engineering, few names hold a torch to the prestige of AJS Profiles. The West Midlands manufacturer has the world’s largest reciprocating grinder and the world’s largest Lumsden grinder. So, it comes as no surprise that when this steel profiling business needed a large heavy-duty cutting machine, it turned to long-standing supplier Kerf Developments.

Steve Harris, director at AJS Profiles,says: “It was 2011 when we bought our first Kerf machine, an RUR3500G, which was soon followed by an RUR2500P plasma machine. So, when it came to making a shift to more advanced technology, the service, support and quality provided by Kerf stood out. Over the years, we gradually moved from the old technology, employing Kerf flame and plasma cutting machines with CNC controls that drastically simplified, modernised and improved our cutting capabilities.”

In total, AJS Profiles installednine Kerf machines over 11 years. Notable among them is ‘the beast’, an RUM3000G with an oxy-arc lance capable of cutting through steel up to 1 m thick. The RUM3000G is a gas cutting machine with a reinforced gantry extending beyond 1.5 m high, making it the only machine of its type in the UK. This extended bridge height accommodates the 1m thick steel plate that AJS frequently cuts, while providing thermal protection with its through coolant design that protects the integrity, repeatability and stability of the bridge during heavy-duty cutting.

The company’s latest acquisition, arriving in September 2022, is its fourth RUR3500G cutting machine, which is the sixth gas cutting machine from Kerf at AJS Profiles.

“The latest RUR3500G can cut plate up to 250mm – and for everything beyond we have ‘the beast’,” concludes Harris.
