If it is not possible to ensure accurate contact between the spherical measuring needle and the surface being measured (for example, in applications such as measuring metal sheets, stamped parts, or thin workpieces), a cylindrical measuring needle can be used. The silver steel measuring needle has undergone heat treatment and grinding processing, and its accuracy can meet extremely high tolerance requirements.
