Life Expectancy of a new PH10M and a refurbished one
新的和修复后的 PH10 M 的平均寿命?

What is it? I replaced my PH10M with a RBE 3 years ago. Now I need to replace it again. What gives?
什么？ 我 3 年前从 RBE 更换我的 PH10 M 。 现在我需要再次更换它。 什么原因？

couple factors influence the life expectancy of a PH9/10 probe head.
$ {, T2 E+ f* c3 C& l/ h
Crashes, probe indexing frequency and the power being supplied to the controller. I have seen some PH9's last a good 10 years+ and others go 3 years because they get abused. Are you sure it's the probe head that is buggered and not the internal head cable in your machine?

Yes, it's the head. I took the head off the column, checked all my connections. What was happening, at 90,0, while measuring as point in the -Y direction, the head would unseat. At first I thought it was the TP200 or module. I put in another TP200 and module, and it unseated again at 90,0. This machine has been running roughly 18 hours a day measuring the same part. It has not seen a crash ever (to the best of my knowledge).

是的，是测头。 我从立柱上拆掉了测头，检查我所有的连接。 故障状态是:在 90,0角度时, 在－Y方向测量点的时候，测头不能抬起。 起先，我认为故障的是TP200 或模块。我换上另外的TP200 和模块，在 90,0角度时,它同样不能就位. 这部机器一天大概18小时测量相同的零件。 它还不有发生一次的猛烈撞击。（据我说知）

仅仅是今天早晨换了一个测头从RBE.它现在正常工作。

& B0 k, B# P3 A* \3 xI'm looking into the Renishaw SP25. I understand this has good qualities when it comes to scanning. I do a fair amount of scanning. However, I'm not sure about the calibration cycle, and time. I'm referring to the time required to qualify a styli change, and new A-B angles.

You might refer to this. It is pretty time consuming. Maybe 10-20 times longer that a traditional trigger probe?? Just a guess on that.

你可能会涉及这。时间是相当长。可能一个传统的接触测头的10-20倍长？只是在那上的一个猜测。

: N( U+ z5 P* \Yes the calibration of the SP25M is time consuming, about 4 mins per probe due to the fact it repeats the routine twice to determine the scanning probe factors. I am very impressed with the probes accuracy on my Mitutoyo Crysta.

# d' N G4 i" f2 |) L4 ` NI am using SP25M with Mcosmos, the accuracy is very good but the time difference is as previously suggested - 15/20 seconds per probe position touch trigger, 4:30 - 5 mins per position scanning factors.
|( v6 Z0 N, GThe scanning times can be changed but the setting used depends on the accuracy req'd

However,I do not find the calibration time a problem as I use the scheduler in the software to run the program lights out during sunday.

does probe ball dia affects the measurent?because i have a probe with 2 mm dia and its giving 3 microns error but as i use the 6 mm ball dia probe , the error goes to 10 microns (its stem length is also bigger than the previous probe).

1 b9 {- U( t& a1 dIf you're trying to check a 3D cone as a 2D dia at a certain Z level then, yes probe diameter will affect accuracy.
If you're look at roundness of a known round item, say a ring gage, then the size of the tip doesn't matter except that larger diameters tend to not be as round as smaller diameters but this is generally a relatively small difference.
The biggest thing that affects accuracy/repeatability/tri-lobing is the length of the stylus. It's much more complicated but generally speaking, if a 1" long stylus results in .0003 of tri-lobing, a 2" long stylus will be around .0006. The same basic concept applies to articulating probe heads. The longer the distance from the fulcrum to the prope tip, the more variance you will have when indexing the probe head. There are many other factors involved but the probe
