Coil Spring Peening
In-line coil spring shot peening machines convey coil springs on parallel rotating rollers with pusher fingers that transport them through the blast zone. Multiple blast wheels target the springs, providing different blast angles that peen the coil springs as they spin through the blast cabinet.
Railway Wheel Peening
Railway wheels are shot peened in an in-line machine with two blast wheels targeting the wheel simultaneously from both sides. Wheels roll in and out of the blast cabinet assisted by automated work handling arrangements. A roller arrangement spins individual wheels in the blast stream.
Both shot peening systems are built with elaborate process controls that monitor and control variables such as blast velocity, blast media size and media flow rate. Shot peening machines are designed with sophisticated yet simple to use controls that provide real-time information of the process and effective means of trouble-shooting.
For smaller quantities of wheels, airblast machines can also be used.
