Automatic Paper Tube Edge Polishing Grinding Machine | NRC MACHINE
1. Product Overview
1.1 Multiple Aliases of This Equipment
This core industrial finishing equipment has three mainstream standard names widely used in global paper tube manufacturing industry:
- Automatic Paper Tube Edge Polishing Grinding Machine (Official Standard Name)
- Paper Tube Edge Grinding Machine
- Paper Core Edge Polishing Machine
1.2 Core Application Scope
The paper tube edge polishing machine is specially developed for post-processing of chemical fiber paper tubes, widely applied for finishing DTY paper tubes, POY paper tubes and all kinds of industrial paper cores. It solves the burr, rough cut, curled edge and fuzzy fiber problems after paper tube cutting, realizing high-precision surface finishing for textile, packaging and industrial paper cores.

1.3 Design Philosophy: Simple, Compact & Stable
NRC MACHINE’s paper tube edge polishing grinding machine adopts integrated compact mechanical layout with simplified transmission structure. Thickened shock-absorbing base frame eliminates vibration during high-speed grinding, guaranteeing long-term stable 24-hour continuous production. Modular assembly design lowers maintenance difficulty and shortens component replacement time.
2. Core Functions & Technical Advantages
2.1 Main Functional Output
The paper tube edge grinding machine focuses on 4 core finishing processes for paper tube end faces and outer circles:
- End face precise grinding
- Outer circle fine polishing
- Full burr removal of cut sections
- Integrated dust-proof & dust collection processing
After polishing, paper tube cuts stay flat, surfaces are smooth without loose fiber curling edges, fully meeting high appearance standards of downstream customers.
2.2 Exclusive Technical Features of NRC Equipment
- Servo positioning system: Real-time accurate positioning of paper tubes, grinding tolerance controlled within ±0.1mm
- Stepless variable speed control: Adjust grinding rotating speed freely to match different paper tube wall thickness
- Replaceable alloy fine grinding head group: Wear-resistant, long service life, low replacement cost
- Double-side synchronous polishing structure: Two ends processed at one feeding, greatly lifting output efficiency
- Flexible angle adjustment mechanism: Adapt to flat edge, chamfer edge and rounded edge processing demands
- Pneumatic clamping & positioning system: Firmly fix paper tubes without extrusion deformation, uniform grinding without dead angle
2.3 Applicable Industry Scenarios
- Chemical fiber textile industry: DTY / POY spinning paper core mass production
- High-end cosmetic & gift packaging: Thin and delicate packaging paper tubes
- Cable & wire manufacturing: Protective industrial paper cores
- Printing & adhesive tape industry: Tape paper tube finishing
3. Automatic Combination & Linked Production Line Matching
To cut labor cost and boost overall workshop productivity, NRC MACHINE supports integrated automated combination schemes matched with paper tube edge polishing grinding machine.
3.1 Multi-Function All-in-One Machine
Integrate inner oil coating, edge grinding and tube bending into one unit, e.g. paper tube oiling-grinding-bending integrated machine. Single equipment replaces three separate standalone machines, saving workshop floor space and reducing manual transferring links.
3.2 Post-Processing Linked Production Line
Combine precision cutter, bending machine, slotting machine and paper tube edge polisher via automatic conveying frames to form one-stop post-processing line for DTY paper tubes.
- Whole workflow: Precise cutting → ring slot pressing → edge polishing → tube bending → slot forming
- Continuous automatic action without manual intervention, cutting labor cost by over 60% and lowering comprehensive production cost.
