Lancoon Electronic Edge Center Finder with LED and Beep for Milling CNC Lathe

At first I did not think it was going to work as the light & buzzer did not activate when hand held & touched on a metal object. However before returning the item I fitted it into a collet on my milling machine and it worked straight away.Set up the fixed jaw on my machine vice to within 0.0003" very easily. I am very pleased with my purchase.

I was surprised how accurate it was having used a wobble stick in the past.

Poor quality items being sold by Amazon with equally poor customer service when there is a problem.

Product listed and described is different than received but is doing the same job.

Works a treat, buzzers not the loudest for a factory setting but with the light it's more than enough

Great product, husband very pleased with quality and ease of use

This is a disappointing product. Despite appearing to be well made, it has significant flaws.Firstly, the ball does not return well to the central position. By displacing it, I could get readings fluctuating by .06mm (the accuracy is supposed to be .01mm).It is long- much longer than it needs to be. In my collet, it projects some 110mm. This amplifies any lack of concentricity, and (because it does not rotate) any runout. It also means the Z axis will often need to be adjusted (that 110mm); another source of error. Whilst I can easily achieve .01mm in my mill with a standard edge finder, this gave errors in the 0.1mm range (measuring a gauge block). It is wholly unsuitable for precise work. I am searching for a use case- I may well return it.

Bought this for work as a CNC machinist. Took me a few parts being wrong to realise that the smaller diameter shaft was bent by 0.3mm
