Our interventions are guaranteed, measurable results and our customers satisfied.
Gear reprofiling
- Cutting tolerance less than 0.15 mm (furnace) and 0.1 mm (grinder) – tolerance close to that of a new crown
- Life extension from 8 to over 10 years (depending on rate of wear)
- Significant reduction in the level of vibration (from 50 to 80% reduction)
- Strict compliance with the involute of the gear circle
- Minimum contact area 70% tooth width (light run-in to achieve 90%)
- 3000 control points on average before and after reprofiling
On-site machining of tires / rollers
- L/R diameter difference less than 0.3 mm
- Flatness tolerance less than 0.07 m
- Haze and out-of-round correction
- Elimination of ovalizations on rollers
Mill journal machining
- Diameter tolerances less than 0.2 mm
- Flatness less than 0.05
- Circularity less than 0.1 mm
- Maximum possible roughness 0.8 microns
Welding
- 12 month warranty on intervention
- Compliance with a strict and supervised recharging protocol
Our results
Our results are measurable and measured
In the field of gears, customers compare the quality and performance of a reprofiling service to a replacement thanks to the vibration level. In the case of a new ring gear: usual maximum vibration 5 mm/s.
The latest Novexa sites show an extremely low vibration level:
- HOLCIM prachovice. Vibration before 37mm/s. After 4 mm/s, March 2013.
- Omya Orgon. Vibration before 15mm/s. After 2mm/s, March 2015.
- Heidelberg Fieni. Vibration before 35 mm/s. After 5 mm/s, April 2013.
- Cement Tasek (Malaysia). Kiln speed before 2.9 rpm. After 4.2 rpm. Gain of 900 tons of clinker per day. August 2015
Interventions minimizing downtime
NOVEXA assure le réusinage d’une couronne en moyenne en 3 jours (temps d’usinage pouvant être compris entre 2 et 5 jours selon la déformation et nombre de postes journaliers).
Our very short intervention times are of course a major source of savings since they avoid production losses linked to machine stoppages.
Machining acceptance is planned after each reprofiling intervention on site. A report of the end of the work is signed by our two companies.
Our customers are satisfied
A satisfaction questionnaire is communicated to customers
The questions are structured around :
- Technical satisfaction (planning, implementation, deadline)
- Résultats en phase avec les objectifs
- Behavior of our teams
- Respect legal testosterone cypionate online safety rules
- Commercial responsiveness
We get an overall average between 85 and 95 on 100
Our objective is a minimum of 80.
Gains
- 2 to 5 days duration of our work
- 0,07 mm (accuracy) comparable to a new crown
- 100 % satisfaction thanks to a 5-point protocol
Following the discovery of a crack over 60% of the width of the tire, the French cement manufacturer decided to limit the risks by opting for on-site repair.
