After my Optimum D 240 X 500 Vario for almost 6 years have been operating without problems, it was more surprising, if not frustrating that I have in recent days with the longitudinal turning constantly produces cones. Since I had already solved the third time the headstock completely and thereby reduce the ever-FU had to reach to the rear screws, bugged me all immensely, because it's also brought the sample turning no improvement. When I opened the garage door, my eyes fell inevitably to my best friend, the thick rubber hammer, which has been so much directed by a single blow. Well, this time, only the front screws are loosened, and shortly afterwards he was already used, a courageous blow to the head stock and the screws only slightly vergespannt. Even when turning on the tension I could see that the rubber hammer method had not failed to achieve, but control is better I thought, and lo and behold, front 29 lathe 4 jaw chuck. 50 mm, 29. 50 mm in the chuck!. It is important to also only here that you know what you are doing and where it strikes, as only randomly turn on the machine could indeed guarantees the opposite achieved! Hopefully, the hammer can now only once a long time to recover because your machine has noticed is that it is hoe, if you do not spurt!.

Hopefully, the hammer can now only once a long time to recover because your machine has noticed is that it is hoe, if you do not spurt!. The result is that eventually turned out better than many times in my adjustment of the machine a few years ago that I would not have thought possible lathe 4 jaw chuck. can I have this morning's no longer held in bed am to 6 ° ° Clock Rise and shine, apply imperative 2 lugs on the gearbox so that it does not move again. If, like me finds that the longitudinal tension produced cones, should be harnessed to sample a large disk into the lathe 4 jaw chuck and turn this plan. With Schraubknaggen how I will make my wedge of C45 steel 10 X 20 mm, can be the whole (pictures will follow when I'm done) without rubber hammer and faster host. In general I think for some time via an optical testing device, such as leaving a pilot laser to verify thus resulting in a lathe 4 jaw chuck or milling head and adjust. Here I have in mind, a laser beam adjusted (pointer) installed in a MK 4 cone and the laser at a 45 ° oblique disk with cross in the 2-3 MK cone hit the tailstock to leave lathe 4 jaw chuck. Such a device could also be used when buying a machine and for examination and this one is a precise alignment later in the actual location does not come around anyway.

With the laser, which is I think not. That would only have a very long way. And assuming for the headstock would be rotated so far that emerges ne Abweicheung of 5 / 10 mm, calculated times back übern theorem, how much the rotation makes the headstock, since then only a few 1/100mm lathe 4 jaw chuck. And all failed because the fact that the laser beam is too thick and you all alone on Ner scale could not even read properly. . Special high-strength cast iron, ribbed and particularly robust against deformation resulting from the locking of the pieces. The outer surfaces of attack and cones are finished grinding. Jaws made of alloy steel Ni lathe 4 jaw chuck. and the importance for accuracy and durability of the platform, are subjected to heat treatment and grinding all surfaces. To realize these conditions have been taken phases and very strict control, honed by experience in this area forty years. Claw independent OMAP platforms, are available for all attacks unified for machine tools. Download our "platform for turning" updated.
