TT 140 tool touch probe for tool measurement
The TT 140 is a triggering 3-D touch probe for tool measurement and
inspection. Your TNC provides three cycles for this touch probe with
which you can measure the tool length and radius automatically either
with the spindle rotating or stopped. The TT 140 features a particularly
rugged design and a high degree of protection, which make it
insensitive to coolants and swarf. The triggering signal is generated by
a wear-resistant and highly reliable optical switch.
HR electronic handwheels
Electronic handwheels facilitate moving the axis slides precisely by
hand. A wide range of traverses per handwheel revolution is available.
Apart from the HR 130 and HR 150 integral handwheels,
HEIDENHAIN also offers the HR 410 and HR 420 portable
handwheels. You will find a detailed description of HR 420 in
Chapter 2 of this manual (see “HR 420 electronic handwheel” on page
74).
