Bkgrnd: Currently we have bolts that over time tighten and rust in place. The current procedure is to use a 1" socket head and handle with the appropriate extensions to break the bolts loose. The handles on these bow considerably and the ratcheting heads frequently fail. The current situation...
I have a manufacturing process that takes place behind steel safety doors. It is similar to a stamping press. I want to measure the movement of the equipment behind the doors while in process. I have been reviewing ideas and because the equipment may be damaged behind the doors I want to...
I have a machine tool with a column of about a foot in diameter. It requires an upper and lower tapered roller bearing and race. The pivot only rotates in and out 180 degrees in about 15 seconds and 3 times an hour. Load is less than 2 tons. Now the question-existing bearings are 20yrs old and...
I am looking to find a piece of inexpensive software that employees can use to track downtime. Today they fill out a papersheet and the data must be entered by hand. This is arduous as we have 3 shift with 15-20 employees and the task is now consuming a bunch of resources-The data I want to...

I do not know of a source but there are locknuts made that do not use a nylon or secondary mechanical device. These are made by dimpling 3 of the outer edges and are used extensively in the lawn mower and yard implement manufactured. They have a dimple on three of the side, which I surmise is to...
Maxbreizh,
Sorry not much help here with cost. We had Cimplicity running so it was just a matter of paying local Fanuc whizz to get a screen made and then hooking it up to our server as the machine tool had the front end loaded when purchased. Look at this site it is a screen capture of our...
