19 Types of Grinding Machines and Their Uses

What Is a Grinding Machine?

A grinding machine is a mechanical tool that’s equipped with an abrasive wheel intended to make shallow cuts on metals or other materials. With the right attachments, it’s also capable of polishing or putting other finishing touches on the workpiece. This type of operation is employed to improve the dimensional accuracy or appearance of a previously machined product. Grinding machines are used on workpieces that need highly precise forms, dimensions, or surface qualities. These machines remove relatively little metal — usually between 0.25 and 0.50 mm in depth. To learn more, see our Grinding Machine article.

How To Choose a Grinding Machine?

There are several factors to consider when buying a grinding machine. Firstly, you must decide what types of materials you’ll be processing. Certain grinders and grinding materials are better suited to some materials than others. Secondly, the machine specifications must be considered, including: the size of the grinding wheel, the input power needed to operate the machine, its frequency and colt rating, the type of control for the grinding head, the spindle orientation, its no-load speed, and the choice between a CNC-operated or hand-controlled grinding machine. All of these will inform your choice of grinding machine. 

What Is the Most Popular Type of Grinding Machine?

Surface grinding machines are the most common style. This type works on either a horizontal or vertical axis and is used to produce either angular, flat, or irregular surfaces. It is popular because it is capable of refining and smoothing processes for a wide variety of metal and nonmetal materials and it’s relatively simple to use.

What Type of Grinding Machine Is Best for Beginners?

Typically, the most ideal type of grinding machine for beginners is the bench grinder. This grinding machine is a relatively simple workshop tool that does not require any experience or complicated operations on the part of the user. There are only a few major components and the machines are easy to understand. A bench grinder is an appliance used to sharpen tools and is a good choice for beginners. 

What Is the Cheapest Type of Grinding Machine?

One of the cheapest types of grinding machines is the bore grinding machine. This is used to bore holes into wood, stone, and metal. It has a relatively simplistic design and is intended for private use. As such, it does not require intricate training or programming like some industrial grinding machines. Additionally, these machines are highly durable, so you’re unlikely to need to repair or replace them often. Finally, bore grinding machines consume small amounts of energy compared to most.  

What Is the Most Expensive Type of Grinding Machine?

One of the most expensive types of grinding machines is the jig grinder. These devices have very small grinding heads in order to cut detailed features into their workpieces. However, extreme precision is expensive to create, calibrate, and operate. To achieve it, they are very complex and thus very expensive. 

What Type of Grinding Machine is Good for Cutting Metal?

All types of grinding machines can be used to cut metal, but some types are better suited to certain material types than others. Belt grinding machines, for example, are specifically designed to shave metal from flat surfaces while gear cutting machines grind specific shapes deep into the part. The volume of metal that needs to be cut must be taken into consideration. For example, large-scale production requires a  grinding machine such as the SMSB SGC 3000 that can grind 40 times more metal than many similar grinding machines. The size of the wheel is proportional to the size of the workpiece. However, all grinding machines are capable of cutting metal and can be used to remove material.

Can a Grinding Machine Be Used for Cutting Plastic?

Yes, grinding machines can be used for cutting plastics if outfitted properly. One of the most common reasons is to crush plastic waste into a usable form for recycling. Materials such as pipes, bottles, and plastic sheets are all examples of plastics that can be cut with grinding machines.

What Are the Uses of Grinding Machines?

Grinding machines are primarily used to change the quality and physical appearance of a workpiece by altering its dimensions, shape, and/or surface. It is an operation that improves upon a previously machined product to achieve light cuts or fine finishes, such as sharpening the edges of blades. This method can be used on a variety of materials, such as: metal, wood, plastic, and stone. However, it is primarily performed on steel or iron. 

Are Grinding Machines Dangerous?

Yes, grinding machines can be dangerous when used improperly or without adequate safety precautions. Their abrasive wheels operate at high speeds to cut through dense materials such as ceramic and metal. Contact with the wheel while in use could therefore easily damage human tissue. Additionally, the grinding action throws off tiny fragments of metal that can harm the eyes. Concrete, meanwhile, will release silica dust that can cause lung irritation and pulmonary diseases after long-term exposure. Proper PPE is critical.

Today, virtually every product made would not exist as we know it without the grinding process. Many of the parts used in cars must be ground. Airplane turbine blades must be ground to fine tolerances. Grinding is the only way the tiny silicon wafers used in computers and cell phones can be made. Even the lawnmowers and axes we use in our yards are ground. The world without grinding would be a different world, indeed.

Machines used to grind in manufacturing are called grinders, or grinding machines. Both terms refer to the same device. A grinding machine uses an abrasive product — usually a rotating wheel — to shape and finish a workpiece by removing metal and generating a surface within a given tolerance. A grinding wheel is made with abrasive grains bonded together. Each grain acts as a cutting tool, removing tiny chips from the workpiece.

Grinding has many functions in the world of manufacturing. In fact, grinding is so important to manufacturing that modern manufacturing would not be possible without grinding. There are many functions that grinding performs, including sharpening tools, finish surfaces, producing close tolerances, and machining difficult material.
