Keyways and splines are generally manufactured through broaching, slotting, milling, EDM or wire cutting. Each method has its own restrictions, particularly in the length they can achieve. Misalignment, deflection, vibration and size limitations are common problems faced by engineering workshops using conventional methods to cut keyways or splines in long parts. However, one Queensland-based company is providing a solution, promising a fast and reliable turnaround, cost effective production, tight tolerances and a high quality finish in difficult parts, with keyways up to 700mm long. Elmass (Australia) discovered this niche market 18 years ago and has been manufacturing precision keyways and splines for a wide range of industries across Queensland and Australia using its patented broaching tools and machines.

As with many other success stories, C&S Engineering and Toolmaking began in a shed in a backyard. Trading since 2003, Craig and Steven Darvill’s business got started after Steven got tired of commuting from The Oaks to Greenacre, and joined his dad – who repaired trucks – in the family workshop, with Steven’s brother Craig subsequently joining in his off-hours. The brothers invested in an old manual machine, and word got out that if a job needed doing, then Craig and Steven could get it done. Neighbours were early customers, then they told their friends, then those friends told their friends and so on. “Once we got our first CNC machine, it was only a month and Craig had to give up his full-time job,” says Steven. “Very daunting, of course, because we’d never taken a wage out of the company at that stage. And I think a month or two after that, once they knew someone was there all the time, we just got flooded. We purchased two more CNC…
