Manufacturer profiles associated with Polishing Spindle Assembly.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The spindle speed range is 500–3000 rpm. Higher speeds are used for fine polishing, while lower speeds are for rough grinding. The actual speed should be selected based on the specific polishing process and lens material, and must be confirmed with the manufacturer for the application.
Radial runout is ≤0.005 mm and axial runout is ≤0.003 mm, per ISO 230-1. These tolerances are critical for optical surface quality, as excessive runout can cause uneven polishing and surface defects. Verify these values for the specific model.
The spindle taper is ISO 40, conforming to ISO 7388-1. This provides a standard tool interface, ensuring compatibility with tooling and fixtures. Always confirm the taper type with the supplier for your machine.
The operating temperature range is 0–50°C; above 50°C may affect bearing lubrication. The maximum load capacity is 150–300 N; exceeding this may cause deflection. The IP rating is IP54–IP65, with higher rating for coolant exposure. These limits must be observed to ensure reliable operation.
