Lens Grooving Machine for Optical Shops
The NH-800S lens grooving machine is a compact bench-top machine for producing controlled grooves along the edges of finished spectacle lenses. It is designed for optical shops and small lens laboratories that need a dedicated grooving step for semi-rimless frame assembly and related lens-finishing work.
Central and Curve-Following Groove Adjustment
The operating mechanism can be adjusted for central, front-curve and rear-curve groove positions. This allows the groove path to follow different lens-edge profiles while supporting consistent placement during manual workshop production.
- Central, front-curve and rear-curve grooving modes.
- Standard cutting-wheel thickness and angle designed for smooth groove formation.
- Large guide roller helps reduce lens deviation during grooving.
- Spherical-connection chuck design helps maintain grip between the lens and chuck rubber.
- Low-noise 90 W electric motor.
- Suitable for grooving compatible plastic and glass lenses.
Compact Optical-Workshop Format
With a documented size of 170 × 210 × 150 mm and a weight of approximately 2.7 kg, the NH-800S can be integrated into compact optical-shop workbenches. Dual electrical configurations are listed for different destination markets.
How It Fits into a Lens-Processing Workflow
The groover complements an automatic or manual lens edger. After the lens outline has been edged, the NH-800S provides the dedicated groove required for compatible frame-fitting workflows. It should therefore be treated as a supporting finishing machine rather than a replacement for an automatic lens edger.
Selection Guidance
Before quotation, buyers should confirm the lens materials, expected daily workload, required groove position, local voltage and frequency, and any preferred cutting-wheel or chuck configuration.
Frequently Asked Questions
Which groove positions can the NH-800S produce?
The source documentation illustrates central-groove, front-curve-groove and rear-curve-groove adjustments.
Can it groove both plastic and glass lenses?
The documented configuration is described as suitable for grooving compatible plastic and glass lenses. Final suitability should be confirmed against the lens material and coating used by the buyer.
Does an automatic lens groover replace a lens edger?
No. An edger shapes the lens outline, while a groover creates the lens-edge channel used in compatible frame-fitting workflows. The two machines perform complementary operations.
