Re: [Emc-users] A puzzler

If the scale is off that far you may want to exchange it for a correctly functioning scale. A certified scale is supposed to be a master gage. When two master gages do not agree there is a problem. On Tue, Aug 6, 2013 at 11:53 AM, andy pugh wrote: > On 6 August 2013 17:37, Stuart Stevenson wr

I am in discussion with a chap who is retrofiting a Hardinge HXL. It has linear scales, interpolator boxes set to 256x and is running a 5i25/7i77 combo. The repeatability is good. Actually is is better than good, it returns to the exact same digit on a 0.1um (0.04") length probe every time. ht

Re: [Emc-users] A question for the Unimat owners.

Gregg; The Emco Compact 5 head used to have a table like this for doing as you say. (take head off of lathe and put it on an x/y table) The colour looks like it's from Proxxon; (Proxon??) The issue with these Emco/Unimat heads is the lack of Z depth setting, etc. On Fri, May 31, 2013 at 5:14 A
