The VAS line of machines are fed from coil. The machines pull the wire from coil, straighten and cut to length.
After cutting, the parts accumulate in a magazine, from where they will be transferred to the next operation. The VAS line can perform a variety of operations, that include cold forming operations such as thread rolling, and material removing operations, such as drilling, pointing, etc...
The parts are automatically transferred inside the VAS machine from one station to the other, and the outcome is a finished part, that does not require any additional operations.
The following operations can be performed on the VAS machine in any sequence:
Samples of parts that can be made on the machine:
The main advantage of the VAS line is the capacity to perform any number and any combination of operations in one machine.
Each operation is done in a separate station, so a few operations take place at any given time, but in separate locations, to keep the high production rate.
The separation of operations make the machine very easy to operate and reduces the risk of one operation to affect the other one.
The flow of parts is done internally, with no external conveyors.
The finished parts eject from one side of the machine, at a rate of minimum 40-50 PPM (for chamfer cut parts) to 200 PPM, for rolled parts.
