Sir,

I have made myself precision CNC VMC 190mmx190mmx90mm with accuracy 10mico m. Machine set right to perfection and is working fine. For completing any job ,need to change tools like end mills , ball mills etc. For this I need to buy Z hight sensor ( touch tool sensor). Sensor hight should be not more tha n 25.4 mm (as restricted due to machine dimensions) and LxB should be around 2"x2" to 4"x4" or so. Could be dialed one, digital one or microswitch type so that NC/NO could be activated on CNC for automated caliberation. I need to buy suitable one or can suggest how to make the same our self.

Shall be grateful for your vaued suggestion.

Regards
