The 3.8×1.8m footprint machine joins the existing Excalibur sawn timber incising machine from Tweddle/Lonza, which was launched in April.
Tweddle said incising of machined timber rounds was more difficult than square timber posts.
The patent-pending design includes controlled rotation through the machine, a built-in laser scanner to identify the diameter of timbers and automatic adjustment of the positioning setting.
Hydraulic cylinders are used instead of a pneumatic system to adjust the pressure of the steel blades.
Feed speeds being quoted are up to 40m per minute, while timber lengths of up to 2.4m and diameters from 65-225mm can be processed, with options for either full post incising or part incising.
Derek Tweddle, of Tweddle Engineering, said significant orders had been received for Excalibur machines from Hales Sawmills and James Davies.
"We are confident that Sidewinder will deliver exactly the same results," he said.
Several different timber incising technologies have recently been developed to service demand for better timber treatment performance following a string of reports of premature fence posts failures across the UK.
