In order for the blade to cut the object completely, even a small chip is not allowed on the cutting edge. Moreover, it is important for the cutting edge to have the required roughness and 5㎛ of straightness. Running machining centers (MCT), making micro-holes, grinding, plating, and other technical know-how on the precision work must be performed to produce this vertical blade.
Name : Vertical blade, U-Blade, NS Blade.
Material : Tungsten Carbide.
Applications : For cutting ceramic and electrodes sheet when MLCC manufactured.
Chips are not allowed on this roll blade. It is important for the roll blade to have required roughness of 10㎛, both internal and external concentricity, and 3㎛ of parallelism on the cutting edge.
Name : Wheel Cutter
Material : Tungsten Carbide
Applications : For cutting ceramic and electrodes sheet when MLCC manufactured.
With existing steel mold, the capacity of maintaining the quality of a very small scale is limited. However, our product using carbide and ceramic can make precise shape. The carbide and ceramic products that are produced by our mold and jig have a good wear resistance. Also, our mold and jig can build precise parts in a short period of time and avoid unnecessary loss of time.
Name : Mold & JIG
The laser defers from the drilling work by making the holes after heat treatment. For this reason, the positions of the holes are made equally whereas the drilling work affects the creating equal hole position. The external size of this vacuum plate requires perpendicularity, parallelism, and tolerance below 5㎛. It also requires 0.2S ~ 0.4S of roughness on the surface. Running machining centers (MCT), making micro-holes, grinding, plating, and other technical know-how on the precision work must be carried out to produce the vacuum plate. In order to produce a large volume of MLCC, vacuum plates are becoming larger accordingly. Moreover, as products are becoming smaller, vacuum plate holes are becoming smaller accordingly
Name : Peeling plate
Material : SUS420J2, SKD11
Applications : For moving 0.8 microns of green ceramic sheet by vacuuming in MLCC stacking machine.
For cutting and making micro holes for the plates whose thickness is less than 6mm, tubes and other various products that require 3D technology work.
-The laser cutting interval is minimum of 20㎛.
-Less than 10㎛ of high dimensional accuracy.
-Laser light source : fiber (300W).
For materials : PCD, PCBN, Ceramic, Tungsten Steel, Sapphire, molybdenum, etc.
The laser can cut up to 2mm in depth and make the surface roughness up to Ra=0.3㎛.
-The laser cutting interval is minimum of 20㎛.
-Less than 10㎛ of high dimensional accuracy.
-Laser light source : fiber (300W)
For materials : Mirror, Ceramic, Printing plates, Coins and medal, Press Stamp, miniature mold, Injection casting mold for toys.
We provide the customers who are in the electrical and electronic industry with various types of ceramic parts that are resistant to wear and chemical.
The ceramic’s surface roughness can be customized to the customer’s request.
Ceramic Inspec : Alumina (Al2O3), Zirconia (ZrO2), Silicon Nitride (Si3N4), Silicon Carbide (SiC), Other Materials.
Standardized cutting tools are not effective to achieve these goals.
Efficient production is achieved when the cutting tool’s quality is improved.
With our special cutting tools, your company can improve your production process and, therefore, create high value products
Diamond tools are effective when cutting those auto parts that are made of aluminum alloy.
Since our special diamond tools have a good wear resistance,
these can help your company increase productivity by saving your production time
