Build a shortlist around the job.
The catalogue references arc grooves in linear-guide sliders, KK / GTH modules, ball-cage and crossed-roller guide components. Confirm suitability against the specific part drawing.
Intermediate length
G410HV
The current G410HV specification lists a 1000 × 400 mm worktable, 1200 / 350 mm X/Z travel and a 24000 rpm spindle. Confirm the grinding envelope for the intended setup.
Longer work envelope

Sources: the current Chuanhe technical workbook for G410HV; the 2026 CNC grinding catalogue, PDF page 7, for the other models. Measurement and weight bases are stated per model. Spindle-centre distance is not usable part height. Machine weight is not table-load capacity. Allow for the wheel, chuck, fixture and operating clearances. Confirm the ordered configuration and acceptance requirements in the technical agreement.
Spindle choices differ by model
G73HV lists 40000 / 60000 rpm, with optional configurations indicated. The current G410HV specification lists 24000 rpm; G418HV lists 30000 rpm. Do not transfer the highest speed to every model.
Grinding range is not clamping area
The current G410HV specification gives a 1000 × 400 mm worktable. It does not specify a separate grinding range or auxiliary-table clamping area. Confirm these dimensions for the intended workpiece and fixture.
Confirm the process before quoting the machine.
Groove geometry
Provide the internal or external groove profile, radii, datum references and tolerance requirements. Confirm wheel access and the grinding path before choosing an envelope.
Spindle and wheel
Confirm the ordered spindle speed and complete wheel geometry. The PDF gives incomplete wheel notation; no missing width or bore dimension is inferred here.
Process and inspection
Review dressing, material, hardness, stock removal and the required finish. Agree how groove geometry, raceway relationships and repeatability will be measured on the sample part.

Common selection questions.
Is 60000 rpm available on every model?
No. The catalogue lists it with G73HV; the other models have different listed spindle configurations. Confirm the ordered option before quotation.
Are all HV-suffix models in this category?
No. G400HV and G500HV are shown in the CNC Right-Angle category. Select by the intended process as well as the model suffix.
Are the listed wheel values enough to order a wheel?
No. The catalogue notation is incomplete. Confirm the full wheel dimensions, specification, speed compatibility and dressing requirements with the factory.
