    Company Introduction

    CPL-Coil to Coil Polishing Line

    Product Introduction

    Coil to Coil Grinding Machine (Wet Type) uses Grinding Oil or Emulsion as a Media to achieve a fine and shiny grinding effect on cold rolled stainless steel coils and it can also remove the defects on Stainless Steel Surface. The Machine is designed to get Finishing No.3 (Coarse Finishing, Abrasive Grain From G60 to G150 ) or No.4 (Fine Finishing, Most Popular, abrasive grain from G180 Or above) and HL Finishing (Hairline Finishing, Characterized by Smooth and long line ).
    Coil to Coil Grinding Machine (Wet Type) is also suitable for the surface treatment of the CRM plates after pickling in Mill; it removes the minor defects and improves the quality of defected products to Qualified Material.
    Coil to Coil Grinding Machine (Wet Type) can process Stainless Steel coil in high quantity and with consistent grain, It is widely used in high-end market such as Decoration, Elevator, Home Appliance Etc.

    Standard Coil to Coil Type Grinding Machine (Wet Type) is mainly composed of a De-Coiling and Re-Coiling System, a 2 Heads Bottom Grinder, a 4 Heads Top Grinder and a 4 Head HL Grinder.
    Bottom Sander is used to remove the inner stress of the Coil, to ensure coil will not get deformed after cutting.
    4 Heads Top Grinder is to ensure the consistent grains from coil head to coil tail and to ensure the flexibility in grinding coils of different width.
    HL Grinder can meet the high-end requirement from customer with Clear and consistent Grains.
    Grinding Heads quantity can be up to customer's requirement (I.E. It can also be 1 Bottom Grinder, + 2 Top Grinders Etc.), or one SB Grinder can be added in the end.

    Heavy-duty built, Coil to Coil Grinding Machine (Wet Type) is featured by:

    --- Perfectly built Recycling System, No environment Pollution -The Recycling System
    combines Rough Mesh Filtration with Fine Paper Filtration, thus Grinding liquid can
    be recycled finely and re-used.
    ---Automatic belt tracking and hydraulic/pneumatic belt tensioning ensure Optimum
    Consistency and minimized operational costs.
    --- Pre-programmable execution settings for part thickness, abrasive belt head Depth
    and brush head depth
    --- Automatic Thickness Adjustment, with Digital Read-Out
    --- Strong Machine Frame, Vibration is well absorbed
    --- Large Contact Roller with Perfect Static as well as Dynamic Balance, High Spinning
    And Long life of Abrasive belts is ensured
    --- Higher Efficiency, with Low Power Consumption-30% Power can be Saved than other
    --- Fast Change of Abrasive Belts
    --- Best Cost Performance

    Cleaning and Drying System:

    --- Integral Design, Main Parts are all made With Stainless Steel, Life Span can be more
    than 20 Years Plus.
    --- Recycling Water Tank, Special Design, 30% Water can be saved
    --- Auto Heating and Temperature-Keeping System, 70% Power can be saved.
    --- High Power Blower to ensure no water mark after Drying.
    --- Direct Lamination after Drying, Film Tension and Braking System, Auto Film cutting
    with high efficiency. Film Bubble Free.

    Line Transmission and De-Coiler and Re-Coiler tension Control System
    --- Transmission Servo Motor: AC Control, 30% Power Saving
    --- De-Coiler and Re-Coiler can open from either Bottom or Top, It works for Coil from
    any mill in the world.
    --- Re-Coiler Tension Unit is our Special Design, Stability has been improved greatly.

    CPL is applied mainly for the removal of small defects in cold rolling SS coil in wet, obtain the decorative finishing, i.e. No.3, No.4, HL, SB & Duplo. The coolant could be emulsion or mineral oil. Coolant filtration and recycling system is essential to the complete line. ZS CPL is designed for cold rolling coil to coil processing up from 100 to 1600 mm width and a thickness between 0.4 to 3.0 mm. WUXI ZS also provide CPL dry. Cork belt will be applied to obtain the finishing similar to Scotch-Brite finishing (SB), feeding speed of dry CPL could be 50m/min or more.


    Typical Applications of NO.4 & HL include: Elevator, Escalator, interior cladding, building facades, Home Appliance, Etc.

    Further treatment is always done upon No.4 and HL surface: PVD Color, Etched Pattern, Anti-Finger Print Processing, To name a few, are the most common one.
