Life Expectancy of a new PH10M and a refurbished one

What is it? I replaced my PH10M with a RBE 3 years ago. Now I need to replace it again. What gives?

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）

I'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.

I'd like hear from anyone already using the SP25, on any system.

我正在考察 Renishaw SP25 。 我知道当扫描的时候它有很好的特征。 我要做一定量的扫描。 然而，我不能确认校准周期和时间。 我指的校准周期是探针值变化和使用新的AB角度。

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.

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.

With the latest release of the Renishaw scanning calibration DLL, Renishaw have reduced the scanning probe calibration times by 35% Using a calibration speed of 20mm/sec, it is now possible to calibrate and qualify a tip in 2 minutes.

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).

Some things to consider here.
7 B" G4 u& h8 i$ U2 R" ^Every probe ball ( stylus ) has some slight deviation from the nominal size.
There is also some pre-travel before the touch trigger probe sends the signal to the controller. How much depends on which touch trigger probe you have (

/ ~% W! J# d) x- x8 f0 _If 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
length is by far the largest contributor. That is, assuming that cleanliness is under control.
& {. v+ [3 D5 F* n1 b2 d
如果你尝试在其中特定z值平面内用一个2维测头测量一个3D立体圆锥体.那么探针直径将会影响精度。
如果你是检查已知项目的圆，例如环规，那么与探针的大小是没有关系的.除了一点小的不同,结果中较大的直径不容易像较小的直径一样的圆。
# n& X& [+ c( A) ?对精度/重复度/偏差影响的最大的是探针的长度.这是更多复杂的,但一般来说，如果这 1" 长的探针误差为.0003偏差, 2" 长的探针将会是.0006 左右. 相同道理适用于关节臂测头。 从支点到探针顶端的距离越长，你标定的测头偏差越多。还牵涉许多其他的因素，但是探针长度是显然最大的因素。 如果其他因素可控的话
