How to Brush Finish Stainless Steel Mitre Corners

Brush finish mitre corners time saving kit

 

The time-consuming practise of creating a brush finish on mitres and outer box sections is now a thing of the past.

The Cibo ‘Time Saving Kit 01’ provides everything you need to achieve a 320 brushed/fine satin finish on stainless steel corners.

It’s quick, it’s efficient, it’s time saving.

 

Let’s see how it’s done…

 

Process Overview

Attach a backing pad and interface foam to your Finipower machine.

Sand the weld with FX87 discs and refine with 237GR discs.

Use Inoxitape alongside a flap wheel to restore the brushed finish.

Clean up with Inoxiclean spray.

How To Brush Finish Mitres and Outer Box Sections – Step 1: Preparation

Starting with the 125VELVZ flexible backing pad with an M14 Spindle – attach this to your Finipower or other variable speed angle grinder.

Next, grab the 125IT and attach to the backing pad. This is a heat resistant interface foam which reduces grinding pressure and increases control so you can remove the weld without undercutting.

How To Brush Finish Mitres and Outer Box Sections – Step 2: Dressing the welds

Simply attach the FX87GR/100/S133 ceramic sanding disc to the interface foam and sand the welded joint flat. Your angle grinder’s optimum rotation speed for this is between 3,000 and 4,000 rpm.

Grinding lines?  Don’t panic – start with the coarsest Trizact grip disc 237GR/A160/S133 and blend the 100 grit sanding lines until smooth. Then repeat with 237GR/A65/S133 for an enhanced result.  This will leave a 280 grit finish on your workpiece.

Once you are satisfied with this result, allow your workpiece to cool.

Abrasive Tip:  Ensure that the sanding lines of the disc are in the same direction as your final brush finish to ensure a fast brushing process.

How To Brush Finish Mitres and Outer Box Sections – Step 3: Restoring the brushed finish

Take a section of MHIT Inoxitape and remove the adhesive strip.  Attach this to your workpiece from the inner to the outer corner.

The FMCM/80/12050 is the perfect tool for your next step. Polish the surface lengthwise towards the inoxitape, remaining on the side of the tape you are currently working on.

Small scratches can be erased at this point by moving the combi wheel in a circular motion.

Now for the easy part! Repeat the process on the opposite side of the weld.

How To Brush Finish Mitres and Outer Box Sections – Step 4: The Clean-up

And just like that, you’re done! For the best finish use SPIC Inoxiclean Spray and a soft cloth to remove any residue from your workpiece. This will also leave an invisible wax coating which will protect the metal from finger marks.  Although not included in the kit, you can grab a can of this here.
