CNC Right-Angle Grinding Machine
Compare two grinding envelopes for rectangular, multi-face work.
Review G400HV and G500HV for grinding vertical faces on rectangular workpieces. Start with the required faces, clamping method, squareness and parallelism, then confirm the cycle and re-clamping sequence.

Build a shortlist around the job.
Rectangular components requiring vertical-face grinding are the starting point. The number of program sides is not proof of single-clamping capability.
500 × 500 mm range
G500HV
Review the larger grinding range when the workpiece requires it. Do not assume greater X/Z travel or spindle-centre clearance.

Source: Chuanhe 2026 CNC grinding catalogue, PDF page 8. The values follow the catalogue; website model names are retained. 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.
A larger range, not more travel
Both models list 1000 / 300 mm X/Z travel, 660 mm spindle-centre distance and 500–4000 rpm. The grinding range changes from 400 × 400 to 500 × 500 mm.
Machine weight is not table load
The catalogue lists 6390 kg for G400HV and 6500 kg for G500HV, including the electrical cabinet. These are machine weights, not permissible workpiece loads. Confirm the part-plus-fixture load separately.
Confirm the process before quoting the machine.
Faces and datums
Identify every face, reference datum, squareness, parallelism and size tolerance. Show which relationships must be maintained through the process.
Cycle and clamping
The catalogue describes selectable 2-, 4-, 6- and 8-side programs. Confirm the actual sequence, turning or re-clamping steps and fixture; do not assume all faces are finished in one clamping.
Wheel and acceptance
Confirm the complete wheel specification, dressing, coolant and inspection plan. The catalogue wheel row is incomplete, so it must not be used as a complete wheel-ordering specification.

Common selection questions.
Why are G400HV and G500HV in Right-Angle, not Vertical CNC?
The website classifies these models by their right-angle grinding application. The HV suffix alone does not determine the product category.
Does the 8-side program mean no re-clamping?
No such claim is made. The fixture, workpiece orientation and confirmed cycle determine how the faces are processed.
Can I select solely from the 400 or 500 model number?
No. Check grinding range, clamping, travel, wheel access, usable height and load together. Both models share several core travel values.
