Examples of popular solutions for mounting abrasive tools in grinding equipment

Grinding machines are designed for various grinding wheel and segment mounting systems. Due to safety regulations, elements that directly match the grinding wheel must meet standard requirements.

Popular solutions for mounting abrasive tools

Among the group of the most popular solutions, one can find:
• center bore and clamping flange
• threaded inserts in the grinding wheel or segment
• mounting by means of a backplate
• segments mounted in the holder
• mounting with a pin.

Designations used in assembly system overview drawings

Q = H / D

Q - diameter ratio
D - outside diameter of the grinding wheel
H - diameter of the wheel bore
df - flange diameter of the wheel adaptor
Ds = 1/2 (D - H) - height of the grinding wheel side surface
h - coverage
b - width of the mounting surface

Mounting system with clamping flanges for grinding wheels with small central bore Q ≤ 0.20

Mounting system using hubbed flanges for flat grinding wheels with large central hole Q > 0.20

Correct arrangement of screws and inserts

Types of flanges used for mounting flat cutting-off wheels (except wheels with diameter D ≤ 230 mm for hand-held grinders)

In this case straight recessed flanges for flat cutting-off wheels are used. Diameter of the flange depend on the operating speed
• flange diameter df ≥ 0.2D when V ≤ 63 m/s and hole diameter H ≤ 0.1D
• flange diameter df ≥ 0.25D when V > 63 m/s.
However, if grinding wheel with large bore is used, the area covered by the flange must not be less than 0.17 M.
