| Yasunaga, Pioneer in the Wire Saw market |
| We have accomplished the enhancement of wire saw's characteristic advantages
in the processing speed, accuracy and efficiency, making the best use of the world-proven
high technologies we have studied. Under the concept of "Upgrading of Productivity"
and "Ecologically Friendly Wire Saw", we head for further developments. |
| What is Wire Saw?...... |
| A wire (a piano wire of φ0.08 to 0.16mm) is wound around several hundred
times along the groove of guide roller. Free abrasive grains (a mixture of grains
and cutting oils) are applied to the wire while it keeps running. The abrasive
grains rolled on the wire work to enable cutting of a processing object into several
hundred slices at one time. It is mostly used to cut electronic materials. |
 |
The free abrasive grains roll to impart fine destruction to the
processing object and wear themselves losing their corners at the same time as
making the wire slim. So, the free grains are fed all the time with a cycle from
a tank. As for the wire, it is replaced with a new one little by little. You can
say that wire saws have far more cutting edges than the diamond blades (with diamond
grains adhered electrically on the external or internal circumference of a thin
disk) competing with wire saws, and it follows that wire saws are superior in
cutting hard materials difficult for processing. In addition, cutting cost can
be figured out clearly depending on the diameter of wire and abrasive grain. |

| Features |
| Productivity |
| ・ |
Improved material yield with fine wire |
| ・ |
Wire reciprocation with high wire speed and
cycle makes cutting speed and cutting precision
improved. |
| |
|
| Operability and Maintenance |
| ・ |
Automatic wire winding at the roller area
can be accomplished by using a piece of tape. |
| ・ |
Easy removal of used wire by utilizing a
split-type of wire take-up reel. |
| ・ |
Simple design by which each drive is run
by a servomotor. |
| ･ |
Front cover opens to 180 degree ease of maintenance. |
・
|
Easy three rollers exchange. |
  
|
Reliability and Durability
|
| ・ |
Linear guides insure the precision straightness
of the lift table movement. |
| ・ |
Three rollers are supported on both ends
by a roller holder in order to maintain the
wire saw's slicing precision and rigidity. |
| ・ |
Rigidity analysis using 3D CAD promotes lighter
machine weight without sacrificing rigidity. |

Lineup for U-Series, SW-Series,
and Sulrry Recycler |
|
| A 6-inch high speed processing machine
using fine wires to process slices or dicing of crystals as well as precision
angle processing represented by quartz AT cutting. |
 |
| Power up succeeding machine of U-400 which was suitable for processing
slices to Si, GaAs, GaP, InP, LT, LN and LBO as well as blocks of crystalline
and a best seller!! |
 |
| The high efficiency machine that is suitable for high-precision processing
of crystal (AT),GaAs, LT/LN, etc. Reduced the cost guide roller consumable
to only one-thirds compared with past model. |
 |
| Achieved constant & stable processing of silicon for solar application
with the φ0.12mm wire. Contribution to cost reduction both by an improved
yield and by high-precision processing. |
 |
| A machine for dicing suitable for processing crystal and ceramic, etc.
It supports a wider cutting width up to 15mm. |
 |
| Slurry Recycler reducing both consumable cost and environmental waste by
effectively reclaiming used slurry. Excellent reclaim rateof usable abrasive
grains from used slurry, which enable to reduce running coat substantially. |
