It is now a standard machine for mold making. A machine that achieves the world's highest level of ultra-flatness, ultra-mirror surface, and ultra-shape creation.
The "SGC-630α・SGC-840α" is an ultra-precision forming surface grinding machine that achieves sub-micron shape accuracy and nanometer surface roughness solely through grinding processing. By transferring its motion characteristics, it enables processing at a level unprecedented in the past. This leads to substantial effects such as improved product yield, increased mold lifespan, creation of high-quality shear surfaces, and reduced working time. All guide structures for vertical, horizontal, and spindle axes employ NAGASE's unique multi-surface constrained hydrostatic structure. This design minimizes both friction and gap deflection to nearly zero simultaneously, enabling nanometer-level repeatability. Additionally, the drive actuators for the left-right and front-back movements are equipped with a unique coreless linear motor. This allows for smooth motion and, in combination with hydrostatic guidance, achieves sub-micron positioning accuracy across a range of speeds from high to low. Furthermore, by adding options such as ultra-precision small indexers or high-precision touch probes, high-precision gear grinding and on-machine three-dimensional measurement become possible. *For more details, please feel free to contact us.

Company information
Nagase Integrates Co., Ltd. develops and manufactures various types of ultra-precision grinding machines, fine processing machines, lenses, turbine blades, gear processing machines, ultra-precision measurement systems, and more. We aim to research and develop each of the technological elements based on the "Ten Major Elements of Ultra-Precision Processing" and establish them. The ultra-precision machines from Nagase are created through the integration (combination and accumulation) of these developed technological elements. Through the pursuit of "limitless zero" achieved by crystallizing these technological elements, we create a unique solution for the world. Moreover, we provide not only machines but also "processing solutions." We can offer optimal proposals from the stages of equipment consideration, specification determination, and test processing.
