Features
A New Standard Machine for Large Molds and Parts Machining
1. Ideal for Surface Grinding of Large Molds such as Motor Core Dies.
Outstanding flatness is achieved over large areas by combining NAGASE's original A non-contact and polyhedral constraint hydrostatic guideway and newly developed high-efficiency, high-thrust linear motors. Capable of machining large and deep length molds by the generous passage width allows.
Suitable for Surface Grinding of Large Molds
Suitable for machining deep length molds.
2. Lightweight and High Rigidity Mechanical Structure
In addition to an ideal machine structure that properly transmits load and machining reaction force to key points in a concentrated manner, the light weight of the moving unit ensures extremely small changes in the distance between the workpiece and grinding wheel and in the travel line during table motion, resulting in high straightness.(Patent design pending)
Unrivaled High Rigidity Mechanical Structure
Achieves lightweight and high rigidity by structural optimization.
3. Compact Installation Space
A thorough commitment to saving space with the installation area is reduced by 50% and the machine height by 30% compared to a conventional column-type grinding machine of the same size.The smallest installation space in the industry compared to the same machining area.Compact size enables transportation without disassembling the main unit.(Patent design pending)
Smallest Machine Installation Space in Its Class
Achieves the industry's smallest installation space for the same processing area.
4.
Supports Crowning Process (OP) and
On-Machine Measurement (OP)
Crowning process (OP) by synchronizing longitudinal and vertical axis is also freely available. Free-form surfaces with extremely small inflection points can be created. The 3D touch probe (OP) enables high-precision on-machine measurement. On-machine 3D measurement (smart 3D probing) is also possible.(OP)
5. Outstanding Usability
Equipped with an interactive CNC control system with a wide variety of functions.It also supports a variety of functions such as combination form grinding (OP) and multi-parts grinding (OP).
6. Swivel Grinding Wheel Spindle (OP) Can Be Mounted
Capable of machining end surfaces and slanted parts of large-size workpieces without changing the setting position.Can be set at any angle in the range of ±45°.
Options
On-Machine Measurement Unit
On-machine measurement is possible by taking advantage of ultra-precise machine motion characteristics and extreme repeatability and positioning.
Swivel Grinding Wheel Spindle
Any angle can be set within the range of ±45°.
Crowning
Achieves overwhelming precision and quality. Creates free-form shapes with minimal inflection points.
Ultra Flat Surface and Shape Forming System "SMART SURF UP"
Machine operation is controlled by corrected values without changing the direct coordinate display. Simple shaping of the workpiece shape and tilt correction are possible.
Straightening Processing and Shape Forming System
"SMART UNDULATION UP"
Automatic straightening processing on a magnetic chuck without using a special jig.
Ultra Right Angle Measurement and Right Angle Processing System
"SMART ANGLE UP"
Easy measurement of right-angle surface and processing of arbitrary right-angle surface are possible without using special jigs.
Balancevector "NB-3012"
It displays the vibration of the grinding wheel rotation, making ultra-precision grinding easier.
Ultimately Efficient Coolant System
「爆削BAKUSAKUⓇ」
Innovative grinding process that blows away conventional wisdom.
