Kraft Engineering, Rotorua - case study

"So you’re not having to overwork, you’re not overworking your grinder to get it to do its job, the disc is taking care of it. And it comes up with a smooth finish, because it’s a lot easier for them."

We look close up with Neville from Kraft Engineering on why Bora9 fibre discs are perfect for Transport Engineering, and why long life sanding discs will give you a better finish.


Application: Heavy Transport Engineering
Product: 125-180mm Bora9 Fibre Disc

Before the Bora9 what have you been using?

We were originally using the Aloxide fibre discs. I’ve tried orange ones and blue ones that are on the market, but you can feel the difference in quality in the Bora9.

What are you using the Bora9 fibre disc on?

Transport Engineering and forestry. The majority is cleaning up excess welds and tidy up prior to painting. Bolsters, chassis rails, all areas where a grinder is not suitable as it leaves marks and dents.

How did you come to using the Bora9 discs?

Our boss had been to truck shows overseas where he had initially seen them, and it was just coincidence that we were both standing there when your Account Manager came through. Boss said that he’d seen the discs before and knew how good they were, and had been thinking about getting some, so we started the ball rolling from there.

What have you noticed about the discs?

We have certainly found with these Boar9 we’re not getting that glazing, I’d suggest we’re probably getting 4 times, possibly maybe even a little bit more, than what I have on previous ones.

Bora9 have that better bite, the actual bite out of it is a lot quicker. So you’re not having to overwork, you’re not overworking your grinder to get it to do its job, the disc is taking care of it.

We’ve got 30 odd guys here that are using these on a regular basis and when they came back to me with the feedback that they had and I’ve gone over and seen the quality of what it’s doing. It just absolutely blew me away.

Over time have you noticed anything more?

They used to get that bluey-purpley look to the metal as it’s heating up. Now with the Bora9 we’re getting that nice clean finish.

Our young fellas are working with these prior to the paint shop. The painter normally at this stage will do a bit of sanding up himself, but he’s’ finding he doesn’t have to do as much as he normally would.

So the guys are getting a better finish?

Most definitely, they’re putting it on and letting it do its job, and it comes up with a smooth finish, because it’s a lot easier for them.



Why do Bora9 fibre discs preform the way they do?

NEW GENERATION CERAMIC GRAIN
Special Designed for cool cutting and long life caused by the sharp crystal shaped grain.

SPECIALISED TOP COATING
New purple coating sanding discs reduces clogging, friction, and heat build up, maintaining the sharpness of the grain. The evenly applied top coating follows the shape of the grain, exposing the whole of the grain, rather than half of the grain being submerged like other standard top coats.
