Crankshaft Grinding Wheels

A type of innovation with the grinding wheels, the crankshaft grinding wheels finds its usage in the different automotive, truck, diesel, aircraft, and small engine manufacturing industry and also in the various engine rebuilding firms that are used to regrind the pins and the bearings. Machines that involve the usage of crankshaft grinding wheels are generally run at a very high speed of 2700m/min; however, some production machines can run at higher speeds as well. The thickness of the crankshaft wheels depends on it’s the type of machine in which it has to be used.

In case of multi-wheel machines, you can use the entire grind all the main bearings at one time only, however the diameter and the thickness tolerances for the set of wheels. This ensures that the wheels are packed with quality and are trued, marked and packed in sets depending on their usage. The amazing and quality crankshaft grinding wheels from the Hindustan Abrasives can be used to hold the corner radii tight and so provides amazing surface finishes of pins, bearing sets and then the side walls of the crankshaft with the plunge grinding.

The basics about the crankshaft grinding wheels

In order to understand the working of the crankshaft grinding wheel, it is important to understand its functionality. The typical crankshaft grinding is a cylindrical grinding of a crank pin or bearing by any form of plunge method. The normal speed of its operation is from 33 to 45 MPS. Quality crankshaft grinding wheel grinds freely, and it generates minimum heat and also maintains its form and size for a sufficient amount of time. Many of the crankshaft manufacturers and regrinding industry use the top-notch crankshaft grinding wheels constructed by Hindustan Abrasives.

The thickness of crankshaft grinding wheel makes the entire difference in the availability limits and the quality of the wheels. There are various processes followed in regards to the construction of the crankshaft grinding wheels and its applications as well. These include:

  • The dressing and the truing of the grinding wheels: This is mainly done in order to restore the original cutting geometry and to make a final product which is flatter and round. The grinding wheels get their flatness and roundness from the dressing and truing of the grinding wheels. This is generally done in many cases by the diamond dressers as well.
  • The Abrasives and the grinding wheel material. The different types of grinding machines are generally used for the different grinding wheel. For grinding wheels that consist o aluminum oxide, cubic boron nitride or diamond. These types of grinding wheels are generally used for producing the high precision grinding or for very hard parts of the machine. The grinding wheels can be used for a lifetime and provide high accuracy in their products and materials.
  • The mesh size of the grinding wheel also makes a good consideration. The abrasive material determines the grain size of the end product. The mesh size of the abrasive material is a measure of the roughness of the grinding wheel which determines the removal rate and the surface roughness of the workpiece of the grinding.

What are the different parts of the crankshaft grinding wheels?

The different types of crankshaft grinding wheel depend on the purpose used. The crankshaft grinding wheels are used according to the quality and the other specifications as well. Hindustan Abrasives manufactures the best crankshaft grinding wheels which are customized for different types of industrial usages. The wheels are also subjected to stringent checks in order to maintain high-quality standards. The components of a crankshaft grinding wheels are:

  • Control side or the drive end: It is used to support the vibration or the damper of the pulley.
  • Counterweights: The weight of the pistons and all the other things are compensated with the help of the crank webs.
  • Main bearing journal: This depends on the version of the crankshaft grinding wheel. The wheels are actually mounted on the main bearing journal in the engine block.
  • conrod journal: The crank radius is defined with ad the distance from the center of the conrod journal to the center of the main bearing journal. The crank radius is also known as the stroke. The displacement or the movement of the crankshaft grinding wheel is dependent on the stroke, diameter and the number of components that are being ground with it.
  • Flywheel side or force transfer: This is used to support the flywheel side.
  • Oil bores: This is used to supply oil to the machinery in order to maintain the efficiency and the working stature of the crankshaft grinding wheels.
The proper dressing of the crankshaft grinding wheel

If you want to use your crankshaft grinding wheel for a lot of time and also indulge in satisfactory work, then you have to properly dress your crankshaft grinding wheel. Also, the wheel has to be dressed every time it is placed on the machines, even when it has not been removed from the wheel center. In order to dress your wheel manually, first, mount the wheel dresser on the grinder table. Then bring the rotating grinding wheel up close to the diamond and then start with the coolant flow. Remember never to dress the crankshaft grinding wheel without the coolant as the frictional heat buildup can cause the diamond to come loose or separate from its mount. Also, improper or lack of lubrication along with cooling can result in abrading of the diamond and will not produce desirable and quality results. There are three types of manual dressing procedures followed. This includes face dressing, radius dressing, and side dressing.
