Profile&Chamfer&Edge Grinding Tools

Product Overview

Quanzhou Cheefung manufactures industrial-grade diamond profile wheels, chamfering bits, and edge grinding tools engineered for CNC machining centers and bridge-cutting lines. Built with high-purity synthetic diamond grits and controlled metal or resin bonds, these tools maintain structural integrity under high feed rates and coolant pressures.

Core Functions

Edge profiling, 45°/30° chamfering, bullnose/ogee shaping, and fine-edge smoothing.

Target Materials

Granite, engineered quartz, marble, architectural glass, and sintered stone.

Core Metric

Designed to reduce edge chipping by 35% and extend dressing intervals compared to standard electroplated alternatives.

Product Range

We supply three primary categories of edge processing tools configured for specific production stages (roughing, shaping, and finishing):

Sintered Metal-Bond Profile Wheels (Roughing)

High impact resistance for aggressive stock removal on hard stone and quartz.

Resin-Bond & Vitrified Edge Grinding Tools (Smoothing & Polishing).

Optimized resin matrices that prevent thermal burning on dark materials while achieving gloss levels above 85 GU.

Electroplated Chamfer Bits (Fast Stock Removal).

Diamond concentration distributed evenly on steel bodies for rapid 45-degree beveling and slotting.

Performance Advantages

Optimized Diamond Retention

Controlled matrix hardness matches abrasive wear rates, preventing premature diamond pull-out and extending overall tool life by 20% to 30%.

Strict Dynamic Balancing

Factory-balanced to G2.5 standards, minimizing vibration at spindle speeds up to 12,000 RPM to protect CNC spindle bearings.

Thermal Stability

Metal-resin hybrid bond formulations dissipate frictional heat rapidly, eliminating thermal micro-cracks on quartz and porcelain surfaces.

Applications

Kitchen & Vanity Countertop Fabrication

Automated edge profiling (Ogee, Bullnose, Bevel, Eased edge) on quartz slabs.

Architectural Glass Processing

Straight and shaped edge seaming, flat grinding, and safety chamfering.

Tile & Slab Processing

Precise 45-degree miter cutting and chamfering for 90-degree seamless corner joints.

Manufacturing Process & Quality Control

Powder Metallurgy Pressing

Diamond grits and metal powders are cold-pressed and vacuum hot-pressed at 850°C to 980°C to achieve a density exceeding 98%.

CNC Body Machining

Tool steel and aluminum alloy bodies are turned on 5-axis CNC lathes to maintain radial runout within ≤ 0.02mm.

Inspection & Quality Assurance

Produced under an ISO 9001:2015 certified quality management system.
100% optical inspection for micro-cracks using dye penetrant testing.
Dynamic balancing test executed on every wheel over 150mm diameter prior to packaging, ensuring compliance with international safety and performance standards (FEPA-aligned).

OEM & ODM Customization

We accept OEM and ODM orders based on your technical drawings (CAD/STEP) or physical samples.

Custom Profiles

Send your DXF/DWG profile files; our engineering team programs 5-axis CNC grinding wheel molds within 48 hours.

IP Protection & Confidentiality

Non-Disclosure Agreements (NDA) are available upon request to secure your proprietary designs and custom geometries.

Private Labeling

Laser etching of your brand logo, grit size, maximum RPM, and traceability batch numbers on the tool body.

Custom Arbor Sizes & Flanges

Tailored to fit Intermac, Bavelloni, Northwood, and generic CNC work centers.

Frequently Asked Questions

Q: What is the minimum order quantity (MOQ) for custom-profile grinding tools?

A: For standard catalog specifications, no strict MOQ is enforced (sample testing is welcomed). For custom profiles requiring dedicated mold setup, the initial MOQ is 5 pieces per specification.

Q: Are Cheefung tools compatible with CNC centers like Intermac and Bavelloni?

A: Yes. Our tools are manufactured with precise bore tolerances and standard spindle mounts (including half-inch GAS threads, ISO40/BT40 tool holders, and custom pin configurations) to fit major CNC stone and glass machining centers.

Q: What coolant pressure and flow rate are recommended during operation?

A: A continuous wet-grinding flow rate of 15 to 25 liters per minute at a minimum pressure of 3 bar is required to flush out swarf and prevent thermal degradation of the diamond matrix.

Q: How do you handle quality discrepancies or after-sales technical issues?

A: Every shipment includes a traceable quality inspection report listing dynamic balance and runout data. In the rare event of a performance variance, our technical team analyzes operating parameters (feed rate, RPM, coolant) and provides a root-cause report or replacement within 3 business days.
