Turret Location

[pinguS]

Has anyone ever had the problem where the machine turret can be zero returned ok / perfectly, but when changing the tool in reverse it either moves too much or not enough. But forward the turret turns correctly.

I am guessing this is just another parameter that tells the turret how much to turn for each tool location.

I know that when I go to tool 1 or home, it always locks in correctly. This is on a Fanuc-18T controller and some on a Fanuc OT.

I had someone look at it and was told to take it apart and check the dowels, they may be worn, but rather try something simpler first.

I have seen them move 2 spots because the parameter was set wrong for the # of tools on turret but it would do this either direction. never seen it work one way but off the other.

This is going to sound weird, but take a look anyway. Check to see if you have an even balance of tool weight around the Turret. I had this problem with a Dainichi BX45 Slant Bed (Fanuc 10T 1987). If there was too much of an inbalance the turret wouldn't lock in the correct position. The easy fix during a rush job would be to call a blank tool then call another tool to keep the turret rotating in a direction for correct alignment. Other than that I think you will have to take it appart.

How old are the machine? Does it turn the turret with servo or hydralic? In either way there are a "gear" that secure the position mechanical, so your machine must miss the position rather much if the mechanical lock doesent find the right position. I should check the beltdrive if the turret is servo driven.

In Some Cases You Can Swap Solenoids If It's A Hydraulic Driven Tool Changer. It Could Be Two Seperate Solenoids That Drive The Magazine Cw And Ccw. If The Problem Switches In The Other Direction Then Your Solenoids Are Bad. If It's Servo Driven Disconnect The Motor And See If The Magazine Flows Smoothly In Both Directions Without Any Bind, And You Might Be Able To Check The Motor As Well By Moving It Disconnected.

I has the same problem here whith KIA SKT15. The motor of turret is an Beta and has 12 defined positions. Maybe are 2 problems. First if the tools are not balanced and the second, the gear in the top of motor maybe slice. Check these problems. It's not problem from motor, because when he stay in the position, the control cutoff the power, and the movement to clamp the turret is hydraulic. If has any difference, will be these problem.
