Case Studies​

Customer creativity​

SituationThis case study shows that a customer may choose to design and build his/her own custom made fixture to be mounted on an air chuck. In this case, a customer has purchased a PML-PAL turning chuck, a precision air chuck, 125mm, NBC type with three jaws, along with air feed tube, and three top jaws.​

milling a tiny workpiece​

SituationThis is a small workpiece 7.5mm long by 7mm diameter. In the production plan, it was directed to machine it in two operations, meaning two clamps, set-up twice. The first one is for milling the front section and the second is for the back section.​

Custom Fixture stationary

SituationAn automotive customer contacted PML-PAL Engineering revealing that he currently manufactures certain part running three milling operations on three machines making one part at the time. Total operating time for each work-piece was around 12 minutes including manual load/unload and manual set up on each machine. The customer asked to help to streamline his production.​

Double diaphragm chuck​

SituationEuropean CNC grinding machine manufacturer was using two diaphragm chucks for two different operations. The customer used one diaphragm chuck (DC) for grinding the first operation inner diameter (ID), outer diameter (OD), and face. Then he used another diaphragm to grind the three dimensionas on the other workpiece side. The total grinding time was 55 seconds. The customer approached PML-PAL engineering to provide a more efficient solution.​

Long clamping solution​

SituationAn automotive parts manufacturer approached PML-PAL engineering with an unusual work piece shape (see photo below). Due to its unique geometry, it was impossible to clamp it one time to complete the machining job. The customer held it in a conventional way on the outer diameter for the first operation, then on the inner diameter for second one, using two machines. Total machining time was two minutes.​
