Ball Screw
Backgauge system with ball screw and slick rod for high precision.
Main Motor
German famous brand Siemens motor improves the life span of the machine and keeps the machine working in low noise environment.
Hydraulic System
Using USA First valve make it more reliable and easy for maintenance. Low sensitivity to oil pollution and assure of long service life
Electrical System
Schneider electrical components make the machine performing well even the electricity is not stable and customers can easily get the replacement anywhere in the world.
Front Table
Transfer balls on table can reduce surface scratches on the sheet and front support arms with ruler for easy feeding.
Ball Clearance Adjustment
Adjust the cutting blades gap by motor according the cutting thickness of the metal sheet can get better cutting performance.
Blade
Blade with 4 cutting edges to provide a longer life span and reducing down time. 6CrW2Si Blades wit high tensile strength for cutting carbon steel and stainless steel.
Safety fence
Protective guards on each side can protect the user during operation.
Hydraulic Hold-down Pads
The lower end of the press cylinder is made of non-metal material, which has certain elasticity and large friction coefficient. When cutting the sheet, the press pad can be in close contact with the material plate to provide sufficient friction to effectively prevent the plate from being shaken during the shearing process.
STRUCTURE WORK
ETERNITY shearing machine frames undergo annealing at over 600⁰ to relieve stress.
This process is indispensible to ensure no deformation in tens of years heavy work.
ADVANTAGES:
- Very stiff and stable base frame
- Deformation simulation software.
- Stress points analysis
- Usage of high-tech boring machines for extreme precision parts.
