How to Reverse Engineer Spur Gears

How to Reverse Engineer Spur Gears A question we get quite often is whether Grob can reverse engineer spur gears for a customer.  Many times a customer may not know the exact parameters of the gear they need, but they do have a sample part in front of them. So, to help the customers try and…

What is Cold Forging and How Does It Work?

What is Cold Forging and How Does It Work? Not to be confused with machining or casting, cold forging is an efficient and economical metal-forming process for the production of high volumes of parts that need added strength. Using our own revolutionary method of cold forging (Grob Rolling), Grob, Inc. manufactures: Spline shafts Timing belt…

Everything You Need to Know About Carbon Steels & Steel Alloys

Steel is the most commonly used metal in the world, finding use in components, products, and structures across a wide range of industries. This popularity is largely due to the material’s inherent strength, hardness, and durability. However, when considering steel as a material for a manufacturing project, it is important to note that steel is…

Cold Formed Timing Belt Pulleys Overview

Timing belt pulley drive systems use teeth and grooves like a chain and sprocket to lock the drive and driven pulley together. These systems keep alignment by maintaining the engagement of precise teeth and pockets between the belt and pulley. The belt allows for a smooth and quiet power transmission while the teeth and pockets…

Do I Need a Band Saw?

In any manufacturing application, it is essential to have the right tools. This means finding quality products from a reliable supplier. Do you need dependable and affordable band saws for your next metalworking or woodworking project? If so, Grob’s got you covered.

Types of Splines Used in Shaft Manufacturing

Splines are grooves or teeth on a shaft that match up with grooves or teeth on another component to transmit torque. Splines are generally used when both linear and rotational motion is desired. There are various types of splines used for numerous industrial applications.

Splined Shafts vs. Keyed Shafts: What’s the Difference?

Click to Expand Most commonly used to transfer power and torque from one part of a mechanical system to another, shafts are long, cylindrical components that serve an assortment of applications, depending on the mechanical system’s needs. Shafts can be comprised of varying materials and fabricated in different lengths and diameters to fit the needs…

Hot Rolled Steel vs. Cold Rolled Steel

Rolling is a metal forming process that employs the use of a series of rollers to alter the shape, improve the uniformity, and/or enhance the mechanical properties of materials. Rolled steel can be categorized into two types—hot rolled steel and cold rolled steel—which demonstrate distinct characteristics that make them suitable for different applications. When choosing…

Involute Splines: Types, Design Considerations, Materials, and Applications

Splines are driven shafts that work by interlocking the grooves of one piece with the teeth of a mating bushing. They are used to facilitate the transmission of rotary motion between two shafts and maintain the alignment of two mated components. Depending on the design requirements and configuration of the system, industry professionals employ a…

Cold Forming 101: Understanding the Process

The Cold Forming Process Cold forming – often known as cold roll forming – is a forging technique used to shape metal materials at near room temperature. Forming metal at cooler temperatures retains or enhances the tensile strength of the material while still allowing high levels of intricate manipulation. Cold forming is a high-speed process that…
