Inch to metric

[EZ3PUTT]

We have a Hitachi Seiki HT-20SII lathe that we want to convert from inch to metric. I have looked in the parameter list for this machine and parameter #6001 bit 0 is to toggle between inch and metric values. I have changed the bit from a 1(inch) to a 0 (metric) but it appears there must be more involved than just this one step. The control still displays 4 decimal places rather than 3 places shown in the metric examples in the book. I do have a call (got voice mail)into our local rep but I expect it to be a while before I hear from him. I did power down and back up after changing the parameter setting.

What is the control on the machine?

Yasnac LX-3 (Seiki Multi)

we run this control before but only i change in the program i think g20 inch g21 metric this change the values from inchs to metric

I have got the machine into a metric mode. However the display is not in metric. I put an indicator on the machine and gave an MDI command of w-1.0 and see .0394" movement on the indicator. But the position display reads .1000 instead of 1.000

I would expect the display to read 3 decimal places rather than 4 like it is. If it did my .1000 display would read 1.000

Anybody got any suggestions.

I have finally achieved the goal of converting our Hitachi from inch to metric. Why do some things that seem so simple have to be so damn complicated. I have seen many machines that do that conversion with a simple parameter change but the Hitachi is not that simple.

I know it's 13 years old, but I need this solution please

Good luck, I sent many of the these machines to the bone yard when I was in different shops.
