Workpiece & target
Define material, allowance and acceptance criteria before choosing the abrasive or geometry.

Material-led wheel selection for external diameters, shoulders and related surfaces.
APPLICATION REFERENCE / HM-G07
Application reference, not a stock SKU. Configuration and supply require technical review.
Shafts; sleeves; automotive and general mechanical parts.
Define the active surface and contact width; review thermal response and dressing needs.
External grinding can engage an OD, end face or groove. Define each active surface, contact width, stock allowance and dressing approach.
Define material, allowance and acceptance criteria before choosing the abrasive or geometry.
Review mounting, access and process motion against the actual machine arrangement.
Agree the drawing and evaluation method before comparing finish, wear or process capability.
| Configuration item | Information to provide / confirm |
|---|---|
| Application-specific inputs | Material and hardness; OD profile; contact width; finish and tolerance. |
| Workpiece | Material designation, hardness, heat treatment and incoming stock |
| Acceptance criteria | Drawing tolerances, form requirements, surface texture and measurement method |
| Wheel & mounting | Shape drawing; outside diameter D, width T, bore H or shank/thread connection, as applicable |
| Abrasive system | Workpiece-dependent abrasive, grain specification, bond and conditioning method |
| Machine & process | Spindle/interface, coolant, dressing arrangement and approved operating limits |
| Quantity & supply | Trial / production quantity; final configuration and availability confirmed after review |
HM-H and HM-G references identify this application collection, not inventory SKUs. Dimensions, construction, supply feasibility and lead time require confirmation.
Send a workpiece and tool drawing where available, material and hardness, machine and interface, stock allowance, finish, tolerance, coolant and quantity.
No. Images are AI-generated family illustrations. Geometry, colors and proportions are indicative; the approved drawing defines the actual tool.
Provide the actual machine model, mounting interface, spindle or feed arrangement and available clearance. A machine brand alone does not establish compatibility.
Specification and acceptance requirements are agreed for the application. Operating speed follows the approved design and actual tool marking; an illustration is not an operating instruction.
Include the application reference, workpiece, machine and quantity. Email drawings or wear photographs to support@hmcbn.com.
