PRECISION SURFACE GRINDING MACHINE
SGW/M SERIES「超精密の匠」による丁寧なきさげ作業により、他にはない高い精度を実現した完全国内生産のロングセラー汎用平面研削盤。700 x 500mmまでのサイズのマシンをご用意。
A Wider Range and Superior Accuracy of Machining Are Reasons Many Users to Choose This Machine
Preliminary machining and finish machining of STAVAX, SKD-II and other die materials, as well as metallic materials such as SS, ceramics, etc., are possible. In addition to manual operation, plunge machining and traverse grinding are also possible by automatic operation.
The rigid machine design ensures heavy-duty grinding with high stock removal.
A standard type for infeed of 2μm - 30μm through the SGM series for minimum infeed of 0.5μm is available.
A large table work area ensures a broad range of 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 right/left-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 slideway.
Stroke adjustment for longitudinal reverse rotations is easily done.
The wide slideway has less load on the unit area so that the oil film on it becomes thin and reduces fluctuation.
The original parts configuration enables smooth reverse rotation of the longitudinal table. This reduces influence on the grinding surface due to reverse shock and demonstrates high-quality machining that conventional general-purpose machines cannot achieve.
The spindle unit employs an super-precision angular contact bearing which supports the radial and axial load securely. It can be used for precision finish machining of hard-to-machine materials and for heavy-duty grinding using high-grit grinding wheel. The Balance Vector (Doctor) NB-3012 for automatically measuring and correcting the balance of the rotating grinding wheel restricts rotational vibration of the grinding wheel and achieves quality machining. In addition, NAGASE’s original hydrostatic bearing and ultra-low vibration motor can be mounted (optional).
The column's front/rear width has been widened to increase rigidity, and a precision guide mechanism is used to achieve highly accurate infeed. With SGM, the minimum infeed amount of the vertical axis can be set to 0.5μm. This micro infeed is also used for precision grinding with a high-grit grinding wheel.
The main body is combined with the oil tank to save space. It is also designed to minimize heat accumulation on the table surface even after machining for a long time. The ribs are arranged appropriately to maintain rigidity of the body.
The display on the operation panel uses a combination of symbol marks and Japanese so even a beginner can operate it easily. Three kinds of automatic cycle grinding including step, traverse and plunge grindings are possible by simple operation procedure.
The workpiece can be set efficiently, not only for manual operation but also for automatic operation.
Accurate grinding is easily achieved through the display of vibration caused by wheel rotation.
High-precision position display improves machining accuracy.
NAGASE will offer diamond/CGN wheels, WA/GC grinding wheels, dressers, flanges and filters according to customer’s grinding needs.
In addition to the above, a variety of options are available. For detailed information, please contact the Nagase sales office.
