Chuck open/close cam hydraulic lock
Before improvement (Fig.1）
・Traditionally, the fixed bolts of each cam that were in an inconvenient position were loosened and the timing of each station was found by trial and error. Once the timing was set, each bolt was tightened and fixed into place, which was very labor-intensive.
・For example if there were 5 stations, it was necessary to loosen and then retighten 10 bolts.
After improvement（Fig.2）
・The hydraulic lock system releases and locks with just one button. Work can be significantly improved and time can be saved in adjusting the chuck open/close timing.
