Assignment From Dad - Stainless Steel Bushing

25/7/2012

6 Comments

 
Couple of posts I did using the iPhone app from Weebly didn't appear.  Rather frustrating with the problematic app.  This makes Blogger more appealing, despite not having my own domain name.

Anyway, I received an assignment from my father, who is in the business of manufacturing syrups for making drinks among others.  One of his distribution channel is to coffeeshops and food courts where the company also supplies dispensing machines that keep the pre-mixed drinks chilled.  The assignment is to make several pieces of bushing for the dispensers in 304 stainless.

The job was previously done by the machine shop next to his SG office.  Due to the small quantity per order (50 each batch), the machine shop is rather reluctant to continue with the work.

I was presented a sample, done by the machine shop, and the original that came with the machine.  The cut out, according to my dad, is not critical.

You can see how badly worn is the used piece.

Picture
I started off by making a piece in aluminium to make sure that what I'm producing can be used.

Picture
The section measuring 16mm in length was turned down to 8.41mm in diameter.

The insert you see on the tool holder is HSS, bought from AR Warner.

It was then drilled with a 5.5mm drill.

and countersunk with a zero flute countersink from Axminster UK.

Parting off to leave a 1.37mm base.

The left is the piece I did in aluminium.  Dad tested it on and I was told that it fits.

Made a trip to King George's Road to get 1.3 meter worth of 304 stainless steel.  The shop is ran by nice people who cut it up into 4 pieces for me.

When through the same process and produced the first piece.  One down, 49 more to go...

Hello Cheng,

I don't know how to use RSS feed. Never tried anyway.

Posting via the Weebly iPhone app is a pain. One incoming call will put an end to all the work. Can't even save as draft. When you see short posts, it is because of the app, wasting all the effort put in. The first attempt is always the meaty one.

More posts coming up. Stay tuned.

I think I need to sell off the Sherline 5410 mill. It is now standing right next to the other CNC Sherline; no room to use anyone of them.

Let me know if you are keen. We talk price later.

Regards,
Wong
