Early Life and Education

As a machinist, your day starts by checking in with your supervisor and reviewing production orders and specifications, inspecting tools and equipment and beginning the machining, fabrication and welding processes. After each process has been completed, quality checks should be conducted before commencing another project; you may work overtime as necessary. Many machinists utilize temporary employment agencies as a stepping-stone into permanent positions.

Professional Career

Screw jacks (also referred to as leadscrews or screw actuators) are devices designed to push, pull, tension, lock, pivot, tilt, roll and lift loads that range from several kilograms up to thousands of tonnes. They typically employ electromechanical actuators that use gearbox assemblies (worm or bevel gears) and transmission products such as leadscrews or ball screws for linear motion conversion; typically found in automated machinery due to health and safety considerations that prevent hydraulic actuation from being the solution of choice.
