 Application of Vitrified CBN Crankshaft grinding wheels

Vitrified CBN crankshaft grinding wheel has CBN abrasive that has superior heat stability which provides excellent performance in super high grinding to process crankshafts processing. Here are some applications of Vitrified CBN crankshaft grinding wheels in various fields and industries.

• Crankshaft grinding. Specialized in AMC Berco machines.
• For automobiles, tractors, vehicles industry
• Precision Machining and Automotive Engine.
• Has been widely used in the processing of hydraulic tappets, glibs, machine tool parts, bearing, and cutting tools.
• It is also used for high-speed grinding. This is why the bond quality, adhesives, and the materials used for the core are carefully designed for safety.

3. Why Vitrified CBN grinding wheels are necessary

This crankshaft grinding wheel is the most recommended tool for automotive, motorcycle, diesel, and other industries because of its large advantages and benefits.

• This crankshaft grinding wheel has 30-50% hardness and balance performance of the wheels which is higher than the standard type.
• Very durable and wear-resistant with its thickness deviation of not more than 0.2 mm. On the other hand, the parallel tolerance of two ends is not more than 0.1 mm.
• It is designed to hard various hardness levels which can meet specific demands in the application.
• The shoulder region is the surface grinding operation while the grinding of the pin is the cylindrical grinding operation. This is very important for a wheel to perform efficiently.
• Includes the latest advances in abrasive grains and vitrified bond technology.
• It has longer dressing intervals and tool life.
• It has a consistent surface finish and high-profile stability.
• It can reduce thermal and mechanical damage to the workpiece.
• Has good self-sharpening ability and can grind a large number of materials.
• It has a high grinding ratio and needs a sufficient supply of coolant in the grinding process.
• It uses a diamond rotary dresser for dressing large scale of production.

4. Crankshaft Grinding Wheel Tips

Selecting the correct product specification is very important to know if the crankshaft grinding wheel suits your machine and other application.

Grinding Wheel Selection

• Choose the appropriate crankshaft grinding wheel according to your application. If you will use it for cast iron, then note in mind that it won’t be that effective on a high-performance type of crank. One wheel cannot do all work at once. Check the variety of abrasive grains, grit sizes, hardness, structures, and bond modifications.
• For cast-iron crankshaft grinding wheels, choose a 35Rc or less Rockwell hardness that can be used on journals.
• For a more versatile crankshaft grinding wheel, better choose a high-performance wheel. Wheels that are domestic, import, or high-performance crankshafts will be good to use. It could be made up of cast or forged steel and nodular iron. Crankshaft grinding wheels like this can remove more materials, can load less, and create a better shape for a longer period of time.
• For diesel crankshaft grinding wheels, choose a 35Rc or more hardness that can be used for journals. Vitrified CBN crankshaft grinding wheels are very ideal for materials such as diesel, high-performance, industrial, and billet steel crankshafts.

Grinding Techniques

After selecting the right wheel, follow the steps carefully while doing the grinding process

• Inspect damages or cracks in the wheel before mounting it. You may do it by thorough looking or by using “Ring Test”. To know if a vitrified crankshaft grinding wheel is of good quality, there should be no cracks and should give off a clearer ringtone when tapped with a wooden or plastic mallet. Bad quality crankshaft grinding wheels give off a dull sound instead of a clear one.
• Checked the maximum operating speed in RPM against the actual RPM in the spindle which will drive the wheel. Use a tachometer and check the speed of the spindle from time to time to ensure consistency throughout the process.
• Pay attention to the condition of the flanges. The flanges must be flat and have an equal diameter with full contact on the sides of the wheel. Use a new blotter every time you mount the wheel.
• Make sure to balance the grinding wheel every time to achieve the best results. To balance the wheels, install the crankshaft grinding wheel on the center and snug the cap screws. Do not tighten the screws. Mount the wheel on a balancing arbor, then place it on the balancing stand.
• The wheel position should be at 12:00, 3:00, 6:00, and 9:00 for it to be balanced. Regularly check the wheel’s position to maintain its balance.
• Install the crankshaft grinding wheel on the machine. The truing process is also necessary to clean up the grinding faces and sides. After that, remove the wheel and recheck the balance. You may adjust the weight if necessary.

Vitrified CBN Crankshaft Grinding wheels are becoming more and more popular these days with their extensive application and contribution to the modern mechanical industry. Obviously, there are lots of advantages and benefits in its usage with its high efficiency, high precision, low grinding cost, and wear-resistant features.
