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
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
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.
＊ ＊ ＊ Grinding of inconel
Let us introduce examples of rotary grinding of various machines units and die parts, using a super-precision rotary grinder with unmatched rotation accuracy and suited to various sizes, as well as examples of indexing grinding, using a super-precision gear grinder which also can grind master gears, spline gauges, and serration punches.

Let us introduce examples of machining large and long parts, such as machine tools and semiconductor units, using an super-precision double column type multifunction grinder suited to a maximum of machining dimensions of “10m x 3m” (*).
(*) For the cross length, we have developed a machine for 12m-size workpieces.
Straight grinding of large workpieces Surface grinding of large workpieces Form fabrication of large workpieces Cutting of large workpieces
Let us introduce examples of micro machining (shaper machining, milling, smart beam machining) of dies for various optical parts and optical films and machining lenses made of glass or ceramic materials, using nano machines with high repeatability and absolute motion accuracy through nano-meter NC command values from small through large areas.

Technical centerCheck the machining result and realize
the difference of our super-precision machine can make. Nagase’s latest super-precision grinder, micro processing machine
and large-size machine are available for you to try at any time.
A large number of machines, including a newly developed super-precision grinder, one-nano processing machine and other large-size machines, are on permanent exhibit in the technical center in order to be used for research & development of optimum machining technology and building technology suited to the machining issues presented in and out of the company.
The technical center accepts test machining, when required, for customers who are interested in selecting and introducing new equipment.
Inform us of your required machine model, size, shape and material of workpieces to test, target accuracy, target machining rate, etc. in detail. Test grinding will basically be available at free of charge (*). Please feel free to try a Nagase super-precision machine.
* For special cases that cannot be handled with tools, jigs and measurement units on hand, separate arrangements may be required. For details, contact the Nagase sales division.Inquiries
Consultations are free of charge. For those who are thinking of introducing any equipment, a machining test will basically be available at free of charge.
Provide the sales personnel at one of our local sales office with information about required accuracy, workpiece size and material. We will review your requirements at our technical center and reply to your inquiry.
