As a premier provider of CNC machining services, AOOM Technology delivers precision-engineered solutions for demanding industrial applications worldwide. Our ISO 9001:2015 certified facility combines advanced multi-axis machining centers with decades of manufacturing expertise to produce components that meet the most stringent quality and performance standards.

Professional CNC Roller Shaft Machining Services

AOOM Technology delivers precision CNC machined roller shafts engineered for high-speed rotating applications in printing, packaging, steel processing, conveyor systems, and textile machinery. Roller shafts demand exceptional concentricity, surface finish, and dimensional stability to ensure consistent operation under continuous load. Our facility combines 5-axis CNC turning and milling, cylindrical grinding, and dynamic balancing to produce shafts that meet OEM tolerances and outperform in demanding production environments.

Key Technical Specifications

• Runout tolerance held to ≤0.01 mm (0.0004 in) after cylindrical grinding
• Surface finishes down to Ra 0.2 μm on journal and bearing surfaces
• Materials: EN8, EN19, 4140, 4340, 17-4PH stainless, 6061-T6 aluminum, and hardness up to HRC 58–62
• Diameter range: Ø10 mm to Ø500 mm; lengths up to 3,000 mm (single piece)
• Cylindrical and centerless grinding for precision OD and ID surfaces
• Keyways, splines, threads, and flanges machined to OEM specifications
• Heat treatment options: induction hardening, nitriding, through hardening
• Surface coatings: hard chrome plating (up to 100 μm), ceramic thermal spray, DLC coating

Applications

CNC machined roller shafts from AOOM are used in printing press cylinders requiring dynamic balancing to G2.5 grade, paper machine dryer rolls with internal steam passage drilling, steel mill work rolls and backup rolls (hardened alloy steel), conveyor drive shafts with helical gear profiles or involute splines, textile calendar rolls requiring mirror-polished surfaces, and packaging machine laminator rollers with precision heat transfer channels.

Quality Assurance

AOOM Technology maintains ISO 9001:2015 certified quality management for every roller shaft project. Dimensional verification is performed using CMM and laser micrometers, concentricity is checked on precision V-blocks with dial indicators, and roughness is verified with contact profilometers. Dynamic balancing reports are provided for high-speed assemblies. Full material certification, heat treatment process records, and surface coating thickness measurements are included with each shipment.
