■ Cutting of reinforced glass by smart beam
Hard-to-cut reinforced glass can be cut with a smooth cutting surface.
■ Cutting of LT (lithium tantalite) by smart beam
Cleaving of brittle material with minimized chipping.
■ Cleaving of monocrystal SiC wafers by accurate roller cutter
Stable machining results with no tool wear even after continuous cleaving
■ Cleaving of aluminum nitride by accurate roller cutter
Cleaving with chipping below 10μm
1. Excellent longitudinal straight motion accuracy and cross axis repeatability
Longitudinal axis straight motion and cross axis repeatability with submicron accuracy.
The correct motion line with no deviation ensures machining with minimal cracks, defects, chipping or kerfs.
2. Excellent parallel motion characteristics by low-vibration structure
The stage feed guideway has a unique non-contact structure and the drive also uses a non-contact super-precision linear motor. The structure with minimized vibration and fluctuation can prevent chipping during machining. 。
3. High-speed machining by high-accuracy linear motor
300mm/sec. feed speed is realized without deteriorating high accuracy to reach unconventionally high-speed machining (blade & dicing type provided separately).
4. Ultra-high accuracy machining, using four original kinds of tools
Unitized tools can be mounted on a system suited to the Customer specifications.
● Smart dicing & scribing type (SPS-L)
Originally developed accurate laser unit to demonstrate optimum wavelength, frequency and output beam according to the thickness and accuracy of materials to machine.
(Test cutting is available.)
This machine is characterized by accurate and efficient scribing and dicing (full cut type) of reinforced glass, LT, LN, sapphire, monocrystal SiC and other clear materials, in particular.
● Roller cutter & scribing type
Highly rigid scribing unit for accurate cleaving by roller cutter
Automatic touching of the tool tip and adjustment of pressure within 100 – 850g are possible. Scribing with minimized tool wear is possible during machining of about 100 sheets of 4-inch monocrystal SiC wafers.
● Hybrid scribing type (SPS-LR)
Unique machining method by combining cleaving with the above smart beam and roller cutter (patented)
This technology was born to achieve breakless cleaving of various materials.
● Blade dicing type (SPG)
This type enables machining by dicing blade. Nagase is proud of our excellent track record of dicing of hard crystal and ceramic materials. For details, refer to “Variations”.
5. Simple operation by inputting data on the touch panel
Complicated machining is simply done through touch panel operation.
6. Automatic alignment by accurate image processing (OP)
By mounting a high-accuracy camera, the machining line is read from the workpiece top surface for automatic positioning before starting machining.
7. Full-automation by cassette-to-cassette operation (OP)
By automatic workpiece supply and exchange unit, cassette-to-cassette automatic machining is possible. Combining with the high-rigidity breaking machine NVK-100, automation through breaking is also possible.
■ High-accuracy and high-speed table operation
High-speed machining at 300mm/sec. with submicron straightness
■ Smart beam unit
Unique and accurate laser machining unit to cope with non-linear machining of transparent materials
■ Touch panel operation screen
Various kinds of machining are possible by simple operation on the screen.
■ Automatic alignment
Highly accurate positioning is automatically done.
■ Automatic workpiece supply & exchange unit
■ Compliance with clean room

○ High-accuracy slicing machine SPG series
Dicing machine with unparalleled rigidity
Deep grooving, one-path dicing and full-cut dicing are possible.
Efficient and accurate cutting and grooving of various materials such as optical glass, ceramics and crystal are possible. Machine sizes 150 and 315 are available.
○ General-purpose dicing machine SGM-52 CE2
Reasonable machine for simple slicing operation
○ High-accuracy breaking machine NVK-100
Chipping of scribed workpieces is fully automatic. Alignment in the Y direction and chipping by breaking are possible. By saving more than 50 kinds of breaking conditions, products can be controlled for each type. By combining with the robot, fully automatic machining is possible on the cassette-to-cassette basis.
○ Machining by breaking machine NVK
Highly rigid original machine most suited for breaking of hard brittle materials such as SiC, GaN, sapphire, ceramics and crystal
