Granite precision inspection platform with stable constant temperature accuracy
Granite Precision Inspection Platform —— Introduction to the Core of Constant Temperature and Precision Stability
Granite precision inspection platform with stable constant temperature accuracy
Cast iron platforms offer superior static load-bearing and heavy-duty crushing capacity, but high-precision inspection and metrology demand temperature stability, low deformation, zero stress, vibration damping, rust resistance, and long-term accuracy maintenance. Granite completely crushes cast iron in the core requirements of precision measurement, and the application scenarios of the two are entirely separate. I. First,…
