Bond Selection Guidance

General guidance for matching abrasive, workpiece material, and bond type. This is advisory — always confirm with your grinding wheel supplier.

Workpiece	Abrasive	Recommended Bond	Notes
Cemented Carbide	Diamond	Resin / Metal	Resin for finishing, Metal for roughing
Ceramic	Diamond	Resin / Vitrified	Vitrified for high-precision
PCD / PCBN	Diamond	Metal / Resin	Metal bond for heavy stock removal
Glass	Diamond	Resin / Metal / Electroplated	Electroplated for profile work
Ferrite	Diamond	Resin / Metal
Hardened Steel (HRC 45+)	CBN	Resin / Vitrified	Resin for general, Vitrified for precision
Tool Steel	CBN	Resin / Vitrified
HSS	CBN	Resin
Cast Iron	CBN	Metal / Vitrified	Metal for roughing
Aerospace Alloy	CBN	Resin / Vitrified	High heat resistance preferred

Concentration reference (FEPA standard):
Concentration = volume of abrasive per unit volume of working layer × 4.
C100 = 4.4 ct/cm³ (diamond) — considered the standard baseline.
Higher concentration → longer wheel life, higher cost. Lower concentration → freer cutting, cooler grinding.

Brief bond properties:
• Resin Bond — Good surface finish, moderate wheel life, self-sharpening. Most common for diamond/CBN.
• Metal Bond — Long life, aggressive cutting, good form holding. Used for roughing and profile work.
• Vitrified Bond — High precision, good stock removal rate, dressable. Growing in popularity for CBN.
• Electroplated — Single layer of abrasive. Good for complex profiles and one-pass grinding.

About this tool

This grinding wheel specification generator helps engineers, procurement specialists, and grinding machine operators create standardized specifications for diamond and CBN grinding wheels.

The generated specification code (e.g., D-150-10-31.75-D91-C100-R) is a simplified, project-specific format designed for clear communication between buyers and suppliers. It does not replace any manufacturer's or industry-standard wheel designation system (such as ISO 525, FEPA, or JIS standards).

For grinding wheel grit conversion between FEPA, ANSI, JIS, and micron standards, see the SINOGRIND grit size converter.

About This Tool

This specification generator helps grinding engineers, procurement teams, and abrasive distributors create structured diamond and CBN grinding wheel specifications. The generated specification can be used for quotation requests (RFQs), technical communication, and internal documentation.

A well-structured specification includes all parameters needed by manufacturers: wheel type, application, workpiece material, dimensions, abrasive type, grit size, concentration, bond type, and quantity.

Frequently Asked Questions

What information do I need for a grinding wheel RFQ?

A complete RFQ should include: wheel type (diamond/CBN), application, workpiece material, wheel dimensions (OD × Thickness × Bore), grit size, concentration, bond type, quantity, and any special requirements.

What is grinding wheel concentration?

Concentration refers to the amount of abrasive grain in the wheel bond matrix. Standard concentration is 100% (4.4 carats/cm³ for diamond). Higher concentration means more cutting points but reduced chip space.

How do I choose between diamond and CBN?

Use diamond for non-ferrous hard materials (tungsten carbide, ceramics, glass, silicon). Use CBN for ferrous materials (hardened steel, cast iron, tool steel). CBN has higher thermal stability for steel grinding.

Generated specifications are preliminary guidance for RFQ communication only. Final wheel design must be confirmed with your supplier based on actual grinding trials.

How to Specify a Grinding Wheel

Specifying a grinding wheel correctly is the single most important step in getting an accurate quotation and a wheel that performs in your process. A complete specification answers five questions: what abrasive, what bond, what shape and size, what grit and concentration, and what operating conditions.

The 5 Elements of a Complete Wheel Specification

1. Abrasive type — Diamond or CBN?

Diamond for non-ferrous hard materials (tungsten carbide, ceramics, glass, silicon, PCD). CBN for ferrous materials (hardened steels above ~45 HRC, cast iron, nickel superalloys).

2. Bond family — Resin, vitrified, metal or electroplated?

Resin for fine finishing and tool grinding; vitrified for form retention and dressable precision work; metal for long life on ceramics/PCD; electroplated for complex profiles without dressing.

3. Dimensions — OD × Thickness × Bore (D × T × H)

Always in millimetres. Example: 150 × 10 × 31.75 mm means a 150 mm outer diameter wheel, 10 mm wide, bored to fit a 31.75 mm (1¼") spindle.

4. Grit size & concentration

Grit controls finish vs. removal rate (finer = smoother); concentration is the abrasive content in the bond layer (C100 = 4.4 ct/cm³ standard).

5. Operating conditions — machine, speed, coolant & stock removal

Tell the supplier your machine type and spindle speed, coolant availability, target stock-removal rate, and cycle-time goals. A wheel specified for a 20 m/s manual surface grinder differs greatly from one running at 50 m/s on a CNC line.

Grinding Wheel RFQ Template & Specification Code

When requesting a quotation from any grinding wheel supplier, include these fields so the manufacturer can quote accurately without back-and-forth:

Abrasive: Diamond (D) or CBN (B)
Dimensions: OD × Thickness × Bore in mm
Grit size: FEPA D/B number (ANSI/JIS equivalents welcome)
Concentration: e.g. C100 (= 4.4 ct/cm³)
Bond: Resin (R), Vitrified (V), Metal (M), Electroplated (E)
Application: operation + workpiece material + machine
Quantity: number of wheels required

Understanding the Wheel Specification Code

The code generated by this tool follows the pattern Type-Diameter-Thickness-Bore-Grit-Concentration-Bond. For example:

D-150-10-31.75-D91-C100-R

reads as: a Diamond wheel, 150 mm diameter, 10 mm thick, 31.75 mm bore, FEPA D91 grit (~91 µm), concentration 100, with a Resin bond. Paste this code directly into your RFQ email — suppliers worldwide recognise it.

Need Help Selecting the Right Grinding Wheel?

These tools provide preliminary guidance based on general engineering principles. Every grinding application has unique variables — wheel specification, machine condition, coolant strategy, and process targets. With over 20 years of experience manufacturing diamond and CBN superabrasive wheels, the SinoGrind engineering team can review your application and recommend a wheel tailored to your exact requirements.
