Understanding The Basics Of Gear Shaping

Understanding The Basics Of Gear Shaping

Gears are a tried and tested way of facilitating torque transfer among mechanical components. Why is torque transfer so important for the functioning of machinery? The answer is straightforward. Torque transfer is the process of converting energy into movement. 

Gears should be manufactured the correct way for them to do the job well. The quality of the metal or alloy used for its manufacturing and the method chosen by the gear manufacturer, each factor affects the performance of gears. 

While broaching, hobbing, and milling are all gear manufacturing methods, in this blog, we will discuss gear shaping, one of the most common methods used by gear manufacturers. 

A brief introduction to gear shaping.


Gear manufacturing using the shaping technique is a largely automated process. Thanks to the advanced CNC machining technology, modern gear manufacturers offer top-notch gears and splines to clients with a shorter turnaround time. Shaping is a simple process where cutting tools are used to form different shapes on a metal blank. A blank is a plain metal disc without any teeth. A blank is converted into gears with the help of CNC machines.

Modern CNC machines manufactured by top brands like Gleason and Mitsubishi are sophisticated, easy to use, and durable. Gear manufacturers shape internal and external gears using CNC machines in a relatively shorter time. Making blind holes and counterbores is virtually impossible using other methods like broaching or milling. Shaping makes it possible for gear manufacturers to make small and detailed cuts with zero errors.

The reciprocating cutting tool in CNC machines shapes the gear blank. Each tooth is cut on the metal blank with precision. You can rely on True Gear & Spline Ltd. for gears of all types. We use Gleason Pfauter PSA 500, Mitsubishi ST40, and Mitsubishi SC40 to offer precise gear shopping services to our clients. 

We manufacture helical gears, ground gears, spur gears, and splined shafts among many other types at the best rates. Call us today to learn about everything we can do for you.
