The Premier Gear story.

Premier Gear and Machining started out in 1988 with a unique idea. The concept was that a company offering cutting-edge precision CNC machining and state-of-the-art gear manufacturing – under one roof – would have a distinct advantage in the contract manufacturing marketplace. Today, more than 30 years and many happy customers later, that simple idea has proven to be an extraordinary success.

Bull Gear Manufacturing.

A Bull Gear is defined simply as the larger of two spur gears that are in engagement in any machine (the smaller gear is usually referred to as a pinion).  So, what makes our Bull Gear manufacturing capabilities special?

It's the applications.  Our Bull Gears are used in some of the most critical mechanical systems in the world, including aircraft and military applications where failure would be catastrophic.  We manufacture Bull Gears using 300M – a 4340 steel with silicon, vanadium, and added carbon and molybdenum.  300M is a vacuum-melted, through-hardening alloy known for its high strength and toughness.  It is also notoriously tough to machine.

The Bull Gears that we produce require a final hardness of 51/56 HRC, and because of this, the manufacturing process is demanding and complex.  We start by rough machining the parts prior to heat treating – except we can't cut the internal spline once the material is hardened, so we have to allow for predetermined thermal distortion, which requires some real manufacturing know-how.  After heat treating, we hard-turn and hard-mill to size, grind the spur gears to size and use EDM for certain features. One of the most challenging aspects of these parts is the flash chrome plating with a .0005” dimensional tolerance, which requires us to hold a .0001” tolerance prior to plating.  The bottom line is: if you don't know exactly what you're doing with these parts, you will end up with scrap.

Bull Gear manufacturing is one example of our specialized capabilities.  We're successful because we control the process.

Quite a few suppliers have tried – and failed – to produce the Bull Gears that we manufacture and ship on a regular basis.  Premier Gear is successful because we know how to control the process with meticulous planning and attention to detail.
