VFD’s for short – are becoming more and more popular within the shot blasting industry. With advancements in technology, these useful tools are easily controllable and add a tremendous amount of flexibility and efficiency to shot blast machines.
If you’re not familiar with shot blast machine VFD’s and their functionality, here is a brief, simple explanation: VFD’s are connected to the blast wheels of shot blast machines and allow machine operators to control the RPMs of the blast wheels. This, in turn, allows them to control the velocity of the shot blast media being thrown from the blast wheels.
Many companies must clean or profile different gauges of metal. Thinner gauged steel or aluminum will likely warp or become damaged if the shot blast intensity is too high. It is also critical in peening applications to be able to control and monitor all shot blasting activities to ensure that strict peening specs are met. Another benefit of having VFD’s is to have the ability to turn down the shot blast media velocity. This allows for cleaning or profiling smaller, lighter parts, which may otherwise blow around the inside of the machine cabinet.
are controlled through the shot blast machines PLC and HMI. Depending on which brand or model of VFD you purchase, many of them are very versatile. You can automate your VFD’s through the PLC to accomplish such things as:
