Tungsten Coating A Flute Corrugating Roller Process Flow :
➊Special alloy steel forge piecial for corrugated roller.
❷4M CNC intermediate frequency quenching machines.
❸The hardness of surface materials is over HRC60 that keeps the flute in a good
state.
❹Computer design to optimize flute Siemens system CNC corrugated roller
grinding machines for grinding flute.
❺SURFACE COATING: (1)tungsten carbined coating: we adopted Oerlikon Metec
HVOF coating machine from Switzerland. (2)Chrome coating: Adopted special
chrome plating technics, and we can get harder and more wearable chrome
coating.
❺Precession polishing technology.
❼Complete product inspection and strict guarantee system.
Tungsten Coating A Flute Corrugating Roller Packaging & Shipping
1.Packing : Use non-fumigation wooden box, it's convenient to customs clearance.Could save customers more time.
2.Delivery Time:Shipped in 60days after payment
Inspection of corrugated roller before installation
(1) clean and check the corrugated surface appearance of corrugated roller (including the quality of surface plating).
(2) clean and check all fastening parts of connection (including internal and external threads).
(3) check the outer diameter and middle height of corrugated roll (the whole roll surface is divided into more than five measuring points from both ends to the middle).The middle and high detection points are odd, and the middle and high data should be symmetrical on both sides.Measure with the outside diameter micrometer of corresponding specification (outside diameter micrometer can be bought commonly by electromechanical company).
(4) check the corrugated roll height.Needle type depth dial meter measurement (needle type depth dial meter is not currently bought in China, must be imported.Or may use the ordinary depth dial gauge to change the system).
(5) clean and check the outer diameter and appearance of each shaft gear of corrugated roller, and measure the outer diameter with the micrometer of corresponding specifications.
