Project flow MediaRepair of the X and Y axis slideway coatings of a Type BMC 40/50 milling machine at the company Cosma Engineering Europe AG, in Oberwaltersdorf (Austria). Project Customer benefits The customer was extremely satisfied with the results. The complete overhaul of a milling machine for the company: Herz Armaturen GmbH, Vienna. Project flow Customer benefits For the company Bosch, WMS Noebauer successfully implemented their desire to increase the productivity of their Helitronic Power Production machine. This machine was specifically upgraded to fulfil its primary application for grinding special step drills. This was also a particularly interesting project for WMS Noebauer. Project flow
The newly installed recirculating roller guidance systems increased the dynamic load rating of the machine from 62.3 kN to 67.4 kN and the static load rating from 96.6 kN to 175 kN. The permissible static moments were also increased from Ma / MA 1.38 kNm to 1.80 kNm and Mc from 1.53 kNm to 2.81 kNm. This resulted in the machine behaving in a much stiffer manner than before the conversion.
Customer benefits The modifications and additional enhancements performed by WMS Noebauer resulted in reducing the grinding time for a step drill from 8 min 20 sec to 3 min 50 sec. This represents a grinding time reduction of some 57%, while simultaneously increasing the grinding quality. The life of the tools has also increased significantly. Although we are used to producing efficiency improvements for our customers, such a significant increase in efficiency is not necessarily an everyday experience and positively surprised not only the company Bosch. Overhaul of two production machines for the company Böhler-Uddeholm Precision Strip. 1. Boehler-Uddeholm Precision Strip “MH600E2” production machine: the overhaul of this machine was performed on-site at the company Boehler. The axis guideways of a MH600E2 Precision Strip machine were completely re-aligned and hand-scraped to re-establish the original machine geometry condition. In addition, the spindle bearings of the milling spindle were renewed, and other important bearings and drive belts were also replaced. The tool changer was put back into operation and adjusted accordingly. 2. Boehler-Uddeholm Precision Strip “MH500W” production machine: the overhaul of this machine involved the grinding and hand-scraping all axis V-guideways and associated rear gripping guides (Hintergriffleisten). Concerning the milling spindle drive; the drive motor was overhauled, the Variator-drive was renewed and all bearings in the headstock replaced. The spindle bearings of the vertical milling head were exchanged and all bellows and slideway wipers were replaced.
Eines unsere Projekte war es eine Walter Helitronic 45 in Pune - Indien zu reparieren.
Mit Tatkräftiger Unterstützung der ganzen Belegschaft konnten wir aber auch in solchen Situationen eine perfekte Reparatur gewährleisten. Da es für uns nie in den Sinn kam Führungsschienen zu tauschen ohne eine Überprüfung der Lage / Parallelität der Führungen zu testen war es die einzige Option den Turm nur mit Menschenkraft aus der Maschine auszubauen. Nach dem tausch aller Führungen und der Montage aller Kugelgewindetriebe wurden alle Elektrischen Kabel, Pneumatikleitungen sowie die gesamte |
