2.VACUUM BRAZING USAGE AND PERFORMANCE
(1)Usage
Vacuum brazing machine is not only suitable for Natural Diamond,Synthetic Mono Crystal Diamond, CVD,PCD/CBN,and Ceramic and so on,but also fit for special brazing in other industries.
(2)Performance
The machine us the light radiant heating method which is different with the traditional vacuum heating equipment,and could increa the heating efficiency a lot.It is a compact device,convenient,elegant and operational ea,especially design for ultra-hard tools industry,largely improve the brazing strength and keep braze stability,the operator can simply handle it without any operational experience.
(3)Advantage
High brazing efficiency;Easy operation;high weld strength;
No oxidation defect and clean surface.
(4)Parameters
Dimension:1000(L)×800(H)×600(W)
Power supply:3pha-380V-5wire(50Hz)/12KW
Chamber:quartz glass tubeφ120×L500×T4
Max temperature:950℃
Vacuum rate:1×10-5Torr
Vacuum process:Cleaning;Fixing flux;Drying;Brazing
CHAPTER2HANDLING AND INSTALLATION OF MACHINE TOOLS
Vacuum brazing machine-ZT-ZKHJ120,net weight is700kg-should be handed by forklift,and just allow to handing from the back(forking identifiers on the packing-ca),
超市入口Fixing position,and then connecting the pipeline for mechanical pump.Connect chiller,and then fill with water.
Electromagnetic valve requires compress air,and then adjust the air compress to0.3-0.4MPa.
Switch on the power,and start the machine.Notice:make an experimental to vacuumize,if normal,start the machine.
The tools for handing and dis-asmbly as followings:forklift,cooling water(purified water),air pump (addition2meters ofφ8mm gas pipe),power wire(4square,3pha-5wire).
