SADDLE TYPE HIGH PRECISION SURFACE AND PROFILE GRINDING MACHINE
Mirror surface grinding, with a high-grit grinding wheel, is possible by utilizing the 0.1μm-infeed characteristics of the vertical axis.
Groove pitch machining is possible and the surface up to the bottom can be mirror-finished.
Complicated shapes, including a groove, can be efficiently machined by contour grinding.
Ultra-precise plunge cutting is possible for extreme micro-grooves.
Grooving, contouring and form fabrication required for forming die parts.
The grinding wheel shape is maintained constant by automatic dressing to achieve high precision machining in both shape and surface roughness (contouring and form fabrication by controlled by Zero-series control software). The hydrostatic spindle can be optionally mounted.
Reduced machining time and improved efficiency machining
* Some models are not applicable.
The main body column has a large width on the front/rear sides and ribs are arranged properly for enhanced rigidity. The vertical axis is equipped with a rigid direct acting rolling guide to accommodate not only an ordinary grinding wheel but also a high-grit CBN and a diamond grinding wheel, achieving an accurate 0.1μm-infeed. A fully closed system by scale-feedback can be mounted optionally on the vertical axis and cross axis for accurate pitch grinding.
The scraping surface, finished by skilled workman spending time and effort, and unique sliding surface design achieve unprecedented straightness accuracy with restricting a change in travelling line during longitudinal-table movement and no change in posture caused by the load. The saddle incorporates a NAGASE original, ultra-wide and ultra-low friction V&V structure, which achieves the most appropriate motion characteristics for accurate shape fabrication.
In addition to the standard type (max. longitudinal feed speed: 25m/min), the SGE-520 Zero3 for high speed feed (max. 40m/min) is also available for more efficient machining. The unique parts configuration enables smooth reverse rotation of the longitudinal table. This reduces damage to the grinding surface and grinding wheel due to reverse shock and leads to high-quality and high-accuracy machining results.
A control system most suited to customer’s purpose can be mounted.
Zero control:
Interactive control software to allow simple setting for ordinary surface grinding and forming grinding through advanced grinding condition setting.
By combining with optional functions, compound shape grinding and multi parts grinding are also possible. Using the CAD/CAM system "CAP-4" also makes it easy to handle complicated grinding wheel shapes and contouring shapes.
Neo control:
Simple touch-panel type control specialized for surface and groove grinding.
It also simplifies teaching operation. Conditions can be changed during grinding and usability of a general-purpose machine is taken over to achieve accurate machining.
Neo control:
Surface grinding, deep-grooving, pitch grinding (optional), plural grinding (optional), plunge traverse (optional)
Zero control:
Surface grinding, deep-grooving, pitch grinding, plural grinding, grinding wheel forming, contouring (optional), compound shape grinding, etc.
Accurate grinding is easily achieved through the display of vibration caused by wheel rotation.
Vibration of the grinding wheel spindle is minimized to realize high rotation accuracy.
The submicron rotation accuracy and rigid structure enable efficient and accurate machining.
Creation of machining programs and data transfer are easily done.
