Ein türkischer Hersteller von CNC-Holzbearbeitungsmaschinen eliminierte Spiel und reduzierte die Häufigkeit des Lagerwechsels von 4 Monaten auf über 24 Monate mit Dongfengs HGR20-Führungsschienen und SFU2010-Kugelgewindetrieben.
Customer Challenge
A CNC woodworking machinery manufacturer in Turkey needed linear guideway rails and ball screws for a new 3-axis CNC router targeting furniture factories. The previous motion system used round shaft linear bearings that showed backlash after 4 months of heavy cutting loads, causing surface finish defects on carved furniture panels and requiring frequent bearing replacement.
Dongfeng Solution
Dongfeng supplied HGR20 linear guideway rails with H-grade accuracy and SFU2010 rolled ball screws with 10mm lead for fast traverse speeds. The GCr15 chrome steel construction with 58-62 HRC hardness provided the rigidity needed for heavy cutting loads. Each batch included dimensional inspection reports and preload verification data to ensure consistent backlash-free operation across all 3 axes.
Results & Valuealue
The HGR20 + SFU2010 combination eliminated measurable backlash after 18 months of continuous operation. Carved panel surface finish quality improved significantly, with the customer's inspection showing a 50% reduction in rework needed for finish defects. The bearing replacement cycle extended from 4 months to over 24 months. The customer ordered components for 50 additional CNC router units in the following year.ear.
