Built for continuous No.4 satin finish production on stainless steel coil, this line takes the coil from uncoiler to recoiler in one pass. Polishing proceeds in defined stages — cut, refine, finish — so No.4 satin is arrived at rather than forced. The result is the familiar brushed satin surface — No.4 — with grain running consistently along the panel.
It handles work up to 2620mm long. The working envelope also covers roller dimensions at 300mm, so the surface stays within tolerance across the batch.
How It Works
This polishing machine is configured for No.4 satin finish on stainless steel coil. Each polishing station is independently loaded, which lets the operator tune the cut and reach No.4 satin on the first pass.
It takes stock from 0.3-4mm in thickness.
In the configuration supplied: working width 900,1250,1500mm, , customized available; system Wet roller grinding; no. of working unit 2-3 grinding heads; roller dimensions 300mm.
Machine Features
- Roll change is done from the operator side, keeping routine maintenance short.
- Each abrasive station is separately driven and loaded, allowing the cut to be balanced across the width.
- CNC control holds head position and pressure to the set value, which is what makes the finish repeatable shift to shift.
- Oil-type grinding carries the swarf away and keeps the abrasive cool, giving a cleaner surface on long runs.
Where It Is Used
- exporters shipping processed coil
- commercial kitchen equipment and countertops
- appliance panels and housings
- shopfitting and display units
Packing & Delivery
Standard export packing, container shipment, 30 days from deposit. Commissioning and operator training can be arranged after delivery.
FAQ
How is the No.4 satin kept consistent from batch to batch?
Every station holds its own set pressure and speed, and those values are stored as a recipe. Once a grade and gauge are dialled in for No.4 satin, the next run of the same specification is called up rather than set again by hand.
What grades of stainless steel can this polishing machine handle?
The austenitic and ferritic grades used for surface-critical stainless steel coil work run through it — 304, 316, 430, 439 and 445 among others. The abrasive sequence is matched to the grade, so mixed batches can be run without changing hardware.
