B107 Grit D125 CBN Resin Grinding Wheel for Tissue Paper Machine Roll Grinding

Product Overview

The B107 Grit D125 CBN Resin Grinding Wheel is a professional-grade, high-performance abrasive tool engineered specifically for the on-machine reconditioning, sizing, and finishing of rolls in tissue paper machines, paper machines, and various industrial roll applications (e.g., calender rolls, guide rolls, coating rolls). Combining Cubic Boron Nitride (CBN) super-abrasive grains with a high-performance resin bond system, it is designed for the efficient, low-heat, and precise grinding of hardened alloy steel roll surfaces. It is an essential consumable for maintaining roll surface quality, geometric accuracy, and operational efficiency in continuous production environments.

Core Technical Advantages & Design Rationale

• Strategic Selection of CBN Abrasive:

  • For Hardened Roll Surfaces: Rolls in tissue machines are typically made from high-hardness, wear-resistant alloy steels. CBN is the optimal super-abrasive for such ferrous metals, capable of cutting hardened surfaces effectively while generating significantly less heat than conventional aluminum oxide wheels. This critically prevents "grinding burn," micro-cracks, or tempering of the roll surface, thereby protecting its hardness and service life.

  • Exceptional Wear Resistance & Form Retention: The extreme durability of CBN grains allows the wheel to maintain a stable peripheral profile and consistent grinding performance over extended periods. This ensures the restored roll maintains excellent cylindricity, straightness, and surface texture uniformity, which are paramount for paper smoothness, caliper consistency, and finished product quality.

• Precise Application of B107 (#120/#150) Grit:

  • Balancing Efficiency and Finish: The B107 grit (approximately FEPA #120 to #150) is a medium-coarse grade. This is chosen to balance material removal rate with achievable surface finish. It efficiently removes minor wear, scratches, or oxidation from the roll surface for dimensional correction, while providing a suitable base for potential finer polishing, often delivering a production-ready surface finish (e.g., Ra 0.4 - 0.8 µm).

• Engineered Resin Bond for Control & Finish:

  • Superior Vibration Damping & Polishing Action: The resilient resin bond absorbs vibrations, promoting smoother operation and better surface quality. Its controlled grain-holding strength facilitates a mild self-sharpening effect and micro-polishing action, contributing to a finer roll finish.

  • Versatile for Dry/Wet Grinding: Formulated for compatibility with both dry grinding and the use of minimal coolant, adapting to various on-site maintenance conditions in paper mills.

• Optimal D125 (125mm) Diameter:

  • The 125mm diameter is a standard size for portable or medium-duty dedicated roll grinding attachments. It offers sufficient peripheral speed for effective cutting while maintaining operational flexibility for on-site or in-situ roll reconditioning, minimizing the massive downtime and cost associated with roll disassembly and shipment.

Typical Application Scenarios

1. Preventive & Corrective Roll Maintenance:

   • Removing minor scratches, pits, or glazed surfaces caused by paper debris, doctor blades, or chemical exposure.

   • Correcting minor roll eccentricity or crown wear from prolonged operation.

2. New/Rebuilt Roll Final Preparation:

   • Performing final precision grinding and surface conditioning on newly manufactured or re-chromed rolls to achieve the specific surface texture and roughness required for the grade of paper being produced.

3. Paper Finish Modification:

   • Adjusting the roll surface roughness through controlled grinding to influence paper smoothness, gloss, or coating holdout.

4. Rapid On-Machine Repair:

   • Executing quick, in-situ repairs of localized damage during scheduled short stops, maximizing production uptime.

Operational & Safety Guidelines

1. Equipment Requirements:

   • Must be used on a dedicated roll grinding machine or a precision grinder with excellent dynamic balance. STRICTLY PROHIBITED on standard bench grinders or angle grinders.

   • The machine spindle must have minimal runout, and effective dust collection/extraction is essential.

2. Grinding Procedure:

   • Mounting & Balancing: Ensure mounting flanges are clean and the wheel is tightened to specified torque. Dynamic balancing is recommended after mounting.

   • Truing & Dressing: A new or worn wheel must be trued using an appropriate diamond dressing tool to restore its roundness and cutting face.

   • Grinding Parameters: Employ a high wheel speed, low depth of cut, and fast traverse rate technique (e.g., use higher end of speed range, light incremental cuts).

   • Cooling: While suitable for dry grinding, using a compatible coolant/mist can extend wheel life and improve surface finish, especially on larger jobs.

3. Critical Safety Protocols:

   • Mandatory PPE: Always wear ANSI-approved safety glasses, a full face shield, hearing protection, and gloves.

   • Machine Guards: Ensure all protective guards are properly installed and secured.

   • Inspection: Always inspect the wheel for cracks or damage before mounting. After mounting, let it run at operating speed for one full minute before contacting the workpiece.

   • Workholding: The roll must be securely locked and driven at an appropriate, slow rotational speed during grinding.

Ordering & Customization
