Machining Examples of Standard Surface Grinder
1. Surface Machining
Preliminary machining and finish machining of 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 fully automatic operation.
2. Efficient machining
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.
Features of Standard Surface Grinder
1. A Wide Machining Area And Excellent Straightness. These Are The Reasons For Many Users To Select Superior Accuracy.
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.
2. Unique Ultra Shock-Free Reverse Table For Machining With An Unprecedented Level Of Quality
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.
3. High-Rigidity And High-Precision Spindle For Finish Machining Of Hard-To-Machine Materials Through Heavy-Duty Grinding
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-number 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).
4. High-Rigidity Column For Submicron Infeed
The column has a large width on the front/rear sides and a precision guide mechanism is employed to enhance rigidity in 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-number grinding wheel.
