High Speed Circular Blades PCB Separation V Scoring Machine
Introduction
Separate machine blade is made from tungsten steel material . Round
steel circular blade is made through precision grinding and
polishing finishing . Its characteristics are high hardness and
high wear resistance, sharp and durable. Its useful life is longer
above 5 times than high speed steel blade, It is applied to feeding
type and V groove plate cutting of the PCB printed circuit board.
Features of blade
1. the content of WC%:90.
2. the content of Co%: 10.
3. high hardness of HRA:92.4.
4. the density of g/cm3:14.4.
5. flexural strength MPa:3400.
6. the elastic modulus GPa:490.
Production
There are two steps of production process of the cutters: tungsten
steel machine blade and blade molding finishing
A. The production process of blade blank material
Dosing (according to the applicable requirements to select tungsten
carbide powder and cobalt powder) →fully
mixing→crushing→drying→sieving→ then adding forming agent → drying
again → sieving to get mixed material→ granulation→pressing→forming
→(German imports low-voltage vacuum sintering furnace) low-pressure
sintering → after sintered blank → testing (nondestructive
ultrasonic inspection)→blank size accuracy test.
B. Blade precision processing.
clamping →fine grinding plane → fine grinding inner circle → fine
grinding positioning holes→ external circle grinding→ rough edge→
fine edge→truing the outer circle→surface polishing→ microscope
inspecting edge→ marking→packing clip to fine.
Descriptions
1. before using , test the depth of PCB board V groove and wear
condition of the cutting tool. Accurately adjust the distance
between upper and down cutter, so as to avoid the knife collision
phenomenon.
2.Select reasonable cutting speed when cut board.
3. blade is razor sharp, Please pay attention to safety when you
install it , so as to avoid unnecessary injury.
4. machine blade razor sharp, please install special Caution!, so
as to avoid unnecessary injury.
5. The whole machine blade is made of high quality tungsten
steel which with high hardness and brittle , it is easy to fracture
when meet the external impact, In addition, the tungsten steel
cutting blade is thin, it is more easily broken when meet the
external shock, so no beating during installation.
