How To Set Up Your Belt Grinder
An often overlooked aspect of grinding when using a belt grinder is what speeds and contact wheels to run. Different materials require different speeds and contact wheels for optimal belt performance and stock removal as well as productivity.
Effect of Belt Speed on Cut-Rate
The higher the belt speed the higher the rate of the cut. This is because as the belt speed increases, more cutting edges are presented to the workpiece. This chart gives a general visual representation of this fact.
Below are some optimal belt speeds that have been found to be ideal for various metals. These speeds may vary a bit depending on the exact grit grade and abrasive grain type, but this should get most operations near the optimal range for high cut rates for improved throughput.
Belt Grinder Speed by Metal Type
Metal: Optimal belt speed (surface feet per minute)
Cast Iron 6,500
Carbon Steel 6,500
Nickel Alloys 6,000
Stainless Steel 7,000
Effect of Contact Wheel Style on Effective Grinding Pressure
The contact wheel should be matched to the grinding operation. Not all grinding applications work well with the same type of contact wheel. Some applications require low pressure while others benefit from high pressure. Conformability might also have to be considered depending on the workpiece. Here are some general guidelines for contact wheel selection that have been proven to be effective for each type of grinding operation.
This chart illustrates how the serrations on a contact wheel affect the pressure that is applied to grinding the workpiece. The configuration of the serrations can optimize belt performance in certain situations. Aggressive serration patterns on the contact wheels are more suited to automated grinding for example.
