Machining examples
■ Fully automatic mirror surface grinder
Automatic dressing and grinding is possible up to a maximum size of “600x400mm”.
Plunge cutting of groove shape is fully automatic.
■ Surface grinding workpieces
Workpieces with the size of “500 x 250mm” aimed at die plates
Efficient surface grinding of middle-size through large-size plates is possible.
Features
1. Machine design suited for high-accuracy machining
“A machine for highly efficient and accurate machining”- Based on this concept, the SGE series includes the choice of hydrostatic spindle (optional) and accuracy rolling spindle (when surface quality and long life is the priority, the hydrostatic spindle is recommended). By attaching the Balance Vector (or Doctor) NB-3012 (optional) for automatically measuring and correcting the rotating wheel balance, the vibration during wheel rotation is suppressed to improve accuracy and quality.
2. Machine designed to accommodate high-number grinding wheel and rigid column to utilize minimum resolution of 0.1μm
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 high-number CBN and diamond grinding wheel, achieving an accurate infeed. A fully closed system by scale-feedback can be mounted optionally mounted on the vertical axis and cross axis for accurate pitch grinding.
3. Excellent straightness and shock-free reverse rotation to achieve high-accuracy and high-quality machining
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 original parts configuration enables smooth reverse rotation of the longitudinal table.
The saddle incorporates a Nagase original, ultra wide and ultra low friction V&V structure.
4. Automatic grinding with usability of a general-purpose machine
The vertical axis and cross axis are NC-controlled. After setting a workpiece, simply set the grinding conditions and press the AUTO button. Not only rough grinding and fine grinding, but also dressing interval setting is fully automatic. In m irror surface grinding, machining conditions most suited to the materials and tools used can be set by NC, thus realizing labor saving and enhanced efficiency in machining.
5. Control system that dramatically improves operating efficiency
A control system most suited to customer’s needs is available.
Zero control:
Interactive control software to allow simple setting, not only for surface grinding and forming grinding, but also for advanced grinding condition setting.
By combining with optional functions, compound shape grinding and multi parts grinding are also possible.
E2 control:
Software to execute automatic dressing and automatic machining for surface grinding and deep 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.
■ Carefully scraped surface
■ Manual pulse generator handle and switches all assembled on the saddle front surface
User-friendly design for manual grinding operation with the usability of general-purpose machine
■ Left operation panel incorporating interactive software Zero series and right operation panel incorporating E2 control software to monitor input values easily
The dressing amount, infeed amount and other conditions can be checked to execute stable and accurate machining.
Options
■ New Balance Vector NB-3012
Accurate grinding is easily done through the display of vibration caused by wheel rotation.
■ Ultra-low vibration motor
Vibration of the grinding wheel spindle is minimized to realize high rotation accuracy.
■ nvac products: Diamond/CBN wheels and general wheels
Nagase offers diamond/CBN wheels, WA/GC grinding wheels, dressers, flanges and filters according to customer’s grinding conditions.
