Example of super-precision forming surface grinding

Nagase super-precision forming surface grinder is seeking to achieve the world’s highest level of flatness, parallelism, squareness and surface roughness.
Let us introduce some examples of mirror grinding, surface fabrication, straight machining and form fabrication (*) of various die parts, precision jigs and gauges. Some of them are made with a precision saddle-type grinder and a general-purpose grinder.
(*) For examples of forming and form fabrication of small parts, refer to related sections.


Mirror finishing Surface fabrication Straight grinding Profiling

Example of super-precision high reciprocating form grinding

Let us introduce examples of contouring, wheel form grinding, microgroove grinding of punches, nests and other small die parts, and turbine blade machining, using high reciprocating forming grinder that achieves submicron profile accuracy and nano-order surface roughness. (*)


(*) Some examples of machining use a super-precision and accuracy general-purpose surface forming grinder.


Contouring Wheel form grinding Microgrooving Serration

Example of super-precision grinding of inconel

High reciprocating grinding achieves high accuracy and efficiency in machining of hard-to-grind materials such as inconel.
Let us introduce examples of wheel form grinding using a single head and double heads.
