Application Guide:External Corner Finishing of Tubular Stainless Steel   

Application:

The removal of Tig welds and finishing of stainless steel tubular hand rails

Finish Required:

A ‘240 grit’ satin finish.  This is the most common satin finish typically seen on high quality commercial property and in the retail environment.

Specific Criteria:

Any flat spots on the tube would be unacceptable as they would be easily noticed in the finished work.

General Guidelines

Successful finishing of stainless steel depends on working at the right speed.  This will prevent ‘work hardening’ the metal and allow better control which in turn will reduce damage and the need for re-working.  

Recommended Tooling:

1. Finipower variable speed grinder

                             or

1. FinitEasy variable speed machine.

Speed:

Product:

Grade:

Disc Size:

3,000 to 5,000rpm

RCD combination disc

Medium

115 x 22 or 125 x 22mm

Method:

Work with the RCD disc on the weld with the machine orientated along the length of the tube (see pic.).  As the weld disappears work the disc from side to side to ensure a good blend is achieved.

Tips:

Low pressure and low speed will improve the life of the disc and control of the operation.

Once a finish has been achieved working at a very light pressure vary the speed to achieve a perfect blend with the existing tube finish.

              Faster = Finer finish

              Slower = Coarser finish
