A machine shop facility contacted me about an issue they were having with metal chips. Their operation used CNC saw machines to cut metal products of various types and sizes to specific lengths. They used belt conveyors that were fitting inside the CNC machines to remove the excess chips to a recycle bin. The cut pieces were then ejected from the CNC machine for the next operation. The issue was when they would cut tubing. For the solid pieces, the conveyors inside the CNC machines would work great to remove the chips. But with hollow stock, the inside of the tube would catch majority of the chips. So, when the part was ejected, chips would accumulate on the outside of the CNC saw machine.
To solve this problem, I recommended a model 151150 Threaded Heavy Duty Line Vac with a model 9034 solenoid. The reason for the Heavy Duty Line Vac is because it is made of a hardened alloy that is resistant to the abrasion of the metal chips. The 1 ½” NPT threaded ends made it easy to attach rigid pipe to both ends. The vacuum end would remove the chips from inside the tube, and the transfer end would send the chips to the recycle bin. Also, with the controls on the CNC machine, the user could send a signal to the solenoid valve to only operate during cutting operations. (An added benefit to save on compressed air.) In his setup, we attached the Heavy Duty Line Vac to the CNC saw machine. It would ride along with the motion of the saw. As the saw was cutting, the Heavy Duty Line Vac vacuumed the chips from inside of the tube. As the saw blade retracted, the Heavy Duty Line Vac would retract as well. This opened the area for the part to be ejected except now there were no chips accumulating outside of the machine.
Keeping work areas clean and recovering debris as it is produced results in a more efficient process and a safer environment.
