The CURTA Collectors and Registry Page. I live in Bonn in Germany and here come my details and my story how. I am a happy owner of some Curtas.

The Winterthur technologies group is one of Europes three leading manufacturers of bonded abrasives. Winterthur grinding wheels specialise in the CNC and gear grinding market. Manufactured in Switzerland to very high standards using only the finest raw materials, which are always subjected to rigerous quality controls.Winterthur wheels remove material faster at exacting tolerances, but without causing metallurgical damage.

The results are not only in grinding cycle times, but more importantly, lower grinding costs per part. Winterthur's 53A & 54A are the wheel of choice on Studer CNC machines, wheather your grinding titanium, chrome or stainless steel.

I run a kellenberger 1500 U at a die shop. I was originally a lathe guy but took on this position when the head grinder retired. I was taught under the method of if its not working, change things until they do. I was never taught to even balance a wheel or proper dressing etiquette and had to learn alot on my own. I don't want to sound green, but I still am. My standard tolerances are +/.

0002 on diameter but I routinely grind locating pins to +/. We recently purchased a Jones and shipman suprema 650. Its a quirky machine and does okay. The problem is that I have no clue where to start on feeds and speeds as what works manually doesn't translate. Right now I grind by 'feel' and with the cnc I can only feed rate override mid cycle. Most of my parts are hardened 4140, 4150, S-7, D-2, or O-1.

Now I am getting into taper grinding and while my parts are coming out good, my cycle times are far to long for us to be profitable. Is there a definitive guide to OD ID grinding that's more advanced with possibly some cnc thrown in? And tips for taper grinding?
