New CNC Milling Centre HURCO

[tomac]

Hope with this new machine the parts get more precise. Had to take out the 915 twice and chop out lots of material to get the reverse gear working.

Hi Tomac,

Danke für die nette Art! Solche Kunden mag ich doch besonders. Am besten zukünftig die Teile selbst machen und nicht durch Dritte verbauen lassen. Für Kritik bin ich immer offen, aber sie sollte von jemandem kommen der wenigstens selbst schraubt und nicht schrauben läßt.

So hab ich das aber schon eingeschätzt!

OK!
This was interesting!
Are there quality problems with Martin's parts?
With the new milling machine I expect nothing less than aircraft precision on the parts.

Martin can you explain for others what issues there has been on parts that you make for us? and how you deal with warranty claims?
But since this is custom parts there is no warranty? right?

You are one of the most serious fabricators i now with very nice parts and quality. "Is this a scratch in your paint?"

Hi,

that´s exactly that what Tomac wanted. I don´t want to justify for anything. I know and lots of customers allover the world know that my quality is at least good (most say superb).

If the goods were bad, why are they still in his car? Look on the picture in the thread about 915-trannies. There you can see, that my rear traverse is still in his car. He complained about that this part was bent by the weight of a type 4 engine. I asked him to send me pics of this and told him that this part already withstood some much heavier Subaru Turbos with 300 PS and that it is nearly impossible. No pictures and no part sent back. He used a 915 gearbox where the inside shiftrod for the reverse gear is not the standard. Did not know that such a shiftrod is existing at all. That was my mistake. So he could not move in the reverse gear. That´s something that you test before you install a gearbox into a car (the gearbox was not from me, otherwise I would have remarked and corrected it before installing into the car). Then he (or the one that does the jobs for him) milled out a section to make it work. He did not measure correctly and had to do this twice then. I feel sorry (in general) that he had the problem with this special shiftrod, but it was not my fault that his mechanic then made wrong measurements and had to mill twice.
I´m not leaning back saying "I´m the only one who offers such parts" and am always interested in receiving feedback on my parts, but it is a very evil and bad way to write in such a forum that my parts have problem with precision.

I keep it open to anybody to do the conversion on his own and not to buy my parts.
It´s always ok to be critical, but this complaint is only based on the wish to give me and my company a bad name.

That´s my opinion and that´s all I will say about this.

The thread was originally started to give you an info about my new milling centre.

@Martin: Good answer! There are always customers that just HAS to make your day bad... even if the parts are ok.

Good luck with your milling machine.
Can you make smaller batches of parts? If i bring the drawings?
What format of drawings do you yse.
I yse Inventor 10,1

@TurboHaraune2:

yes Inventor fits perfectly, but can also work with Unigraphics (friend) and Catia V5 (brother). Bought my own CAD/CAM from OneCNC, and so I can work with all usual data-formats (iges, step, sat, dxf,.....). From a 3D-model to a milled product it is no long distance with such a CAD/CAM. Reason is my 4-valve-DOHC-project also.

But please send me an email if there are more details, or call me.

I'm still waiting for a reply to my email I have send. If the manufaturer of these parts does not anwser this is the only way to make customers aware that they have to be carefull when installing these parts. They don't just fit. It does not matter if a thirth party did the initial installation. Period. The parts are still good and make life a lot easier.

@tomac:

here´s the answer I mailed you on the same day you sent your complaint:

Hallo Herr Jenter,

ich vermute dass Ihr Auto als einziges mit Typ4 solche Probleme bereitet. Keiner meiner Typ4-Kunden hatte bisher solche Probleme, Ebenso laufen unsere Subaru-Turbo-Umbauten alle super mit der Traverse, obwohl der Subaru-Motor ca. 25-30 % schwerer ist als ein Typ 4. Von Leistung und Drehmoment ganz zu schweigen. Konstruktiv bedingt kann sich die Traverse eigentlich nur sehr schwer verbiegen. Bitte schicken Sie mir Bilder davon.

Zum Thema Rückwärtsgang kann ich nur sagen, dass es eine bestimmte Innenschaltstange bei dem 915 gibt, bei der es zu diesem Problem kommt. Wenn schon nachgefräst wurde - was grundsätzlich in diesem Fall eine gute Sache war - hätte das genaue Maß vorher ermittelt werden müssen. Dann hätte es nachher gepasst. Soviel zur Nacharbeit (-:.

Soll "soviel zur Passgenauigkeit" etwas bestimmtes sagen, oder ist das hier nur so eine Floskel?


That´s the way how I care for customer complaints. If you did not open the mail or anything else, then it´s not my fault. I can prove that this mail was sent on the 11th of September, 6.14 pm.

So, please don´t say I didn´t care. I never received any pics from you to prove the problem with the rear mount. I feel sorry for the problem with the nosecone in general, but I´m not to blame for installing a gearbox without checking if all gears can be moved in. If this was done a second or a third time, after milling out the nosecone (what was my problem) you or your mechanic are to blame for doing a mistake a second or a third time.
