Exploring the Different Types of Grinding Machines

Not to be confused with a milling machine, a grinding machine is a heavy-duty machine that's used to remove material from the surface of a workpiece. While milling machines feature a rotating cutting tool that's placed against a stationary workpiece, a grinding machine features a rotating grinding wheel, which is also placed against a stationary workpiece. There are several different types of grinding machines, however, each of which works in a different way.

 

Bench Grinding Machine

Bench grinding machines are characterized by their bench-like shape. They usually feature two different grinding wheels: one for the removal of material and another for finishing processes. They are called "bench grinding machines" because their grinding wheels are secured to the top of a workbench. As a result, bench grinding machines are easy and convenient for manufacturing workers to use.

 

 

Belt Grinding Machine

Belt grinding machines are characterized by the use of a belt sander. Like other grinding machines, they are designed to remove material from workpieces, thereby making workpieces smaller and with a smoother and more desirable surface. With belt grinding, the belt is coated in an abrasive material, after which it's run against the surface of a workpiece until the desired results are achieved. Belt grinding is most commonly performed on metal workpieces, though it supports workpieces made of other materials as well.

 

Surface Grinding Machine

A third type of grinding machine is a surface grinding machine. Surface grinding machines are unique because they feature an adjustable head. The head on a surface grinding machine can be lowered down to the workpiece. Once lowered, the head can then rotate back and forth under the machine's grinding wheel.

While belt grinding machines are typically used for finishing processes, surface grinding machines are most commonly used for material removal. When compared to other grinding machines, surface grinding machines are able to remove significant amounts of material, making them desirable for such applications.

 

Gear Grinding Machine

 

 

Gear grinding machines are designed specifically for the removal of material from shafts. Using grinding wheels, they can grind the center of a shaft with extreme precision.

 

Die Grinding Machine

A smaller and more basic type of grinding machine is a die grinding machine. Unlike the other machines listed here, die grinding machines are handheld. They are connected to an air compressor, which works to power the machine's grinding wheel. If an air compressor isn't used, the die grinding machine will likely receive power from an electric motor.

Why Spiral Bevel Gears Are So Widely Used in High Load Applications?

Bevel gears play a key part in power transmission roles, being used in helicopters, power generation machines and more; essentially, instances when power musty be transferred across two non-parallel axes. A spiral bevel gear is one which has helical teeth. Like the helical gear, using a spiral bevel gear brings the benefit of less vibration and noise. Spiral bevel gears are used often in vehicle transmissions as drive from the driveshaft must be turned 90 degrees to drive the wheels.

 

Despite the more complicated manufacturing processes that are required to make spiral bevel gears and that two interfacing spiral gears are usually replaced as a set, spiral bevel gears are the gear of choice in high load situations.

 

Another type of spiral bevel gear is the hypoid gear. It is distinct from the spiral bevel gear in that the axis of the gear does not intersect with the axis of the meshing gear. Hypoid gears amplify the benefits of the spiral bevel gear. Since multiple teeth mesh together at the same time, they are able to handle larger loads, while retaining the other useful characteristics of spiral bevel gears.

 

 

Some benefits of using spiral bevel gears:

 

ㆍReduced heat - Spiral bevel gears produce less heat than bevel gears in similar conditions. It makes their use desirable in situations where heat build-up can adversely affect operation of nearby components or safety.

 

ㆍHigh torque - Spiral bevel gears have a relatively larger tooth area, and one which is in mesh. As such they are perfect for high torque and high speed application. It is also one of the reasons why they are used in large trucks.

 

ㆍOffset - With no offset, the teeth of spiral bevel gears slide little between each other. This increases the effectiveness and efficiency of the gear and reduces heat generation.

 

ㆍSmoothness - Abrupt power delivery has the potential to both damage machinery as well as compromise safety; which is why spiral bevel gears with their smooth engagement are preferred when gear engagement should not upset drive.
