LY-316 Three-wheel lens hand edger
A three-wheel lens hand edger with 180#, 280# and 400# grinding wheels side by side, so coarse grinding, fine grinding and the finishing edge are done on one machine. A 900 mL water tank cools the wheels, a cooling fan keeps the motor cool and an LED lamp lights the work. For polycarbonate lenses, the wheels can be customised with a dedicated PC wheel.
Delivery, packing and documents
What the LY-316 does
Three wheels, one machine
The 180# wheel takes off material fast, the 280# wheel refines the edge and the 400# wheel finishes it. Move the lens from wheel to wheel without changing anything.
Custom PC wheel
Polycarbonate tends to smear and clog a wheel made for resin. Order the LY-316 with a dedicated PC wheel and grind PC lenses cleanly; tell us which lenses you edge and we set up the wheels to match.
Water cooling
A 900 mL tank with a brass tap feeds water to the wheels. Wet grinding keeps the lens cool and keeps the dust down, and the tank does not need refilling after every job.
Cooling fan
A fan behind the vents runs at 3,000 rpm to carry heat away from the motor during long sessions.
LED work lamp
An adjustable LED spot (DC 12 V, 1 W) lights the wheel, so you can see the edge you are grinding.
Separate switches
The motor and the lamp have their own switches, and a felt pad on top gives the lens a safe place to rest between passes.
A closer look at the LY-316
Combined wheels
Coarse, fine and finishing wheels side by side, with the grit printed above each one.
Aluminium motor, copper winding
The aluminium housing sheds heat and the copper winding keeps losses low, for steady running.
900 mL water tank
Continuous water to the wheels for cooling and less dust, with fewer refills.
Cooling fan
Vents and a fan move heat out of the housing. Illustration.
LED spot lamp
Lights the grinding point for more accurate and safer work.

Choosing and using a three-wheel hand edger
What a hand edger is for
An automatic edger cuts the lens to the frame shape. A hand edger is where the edge is touched up: taking a lens down a little more, breaking a sharp edge, putting on a safety bevel or finishing a lens that came back from the frame. Many labs keep one next to the automatic edger, and small shops that buy edged lenses use one on its own.
Why three wheels
With one wheel you compromise between speed and finish. Three wheels let you go from 180# to 280# to 400# in turn, so material comes off quickly and the edge still ends smooth.
PC lenses
If you edge many polycarbonate lenses, order the LY-316 with a PC wheel. A wheel made for PC cuts the softer material instead of smearing it.
Check before you order
- Voltage and plug for your country.
- Standard wheels or a custom PC wheel, and which lenses you edge most.
- Spare wheels, if you want them in the same shipment.
Good practice
- Fill the tank and open the tap so the wheels run wet.
- Switch on the motor and the lamp.
- Start on the 180# wheel, keep the lens moving and use light pressure.
- Refine on the 280# wheel, then finish the edge on the 400# wheel.
- Check the size in the frame before taking off more.
Care
- Empty and rinse the tank at the end of the day.
- Wipe slurry from the wheels and the work area.
- Keep the vents clear so the fan can cool the motor.

LY-316 questions
What is a three-wheel hand edger?
A three-wheel hand edger is a bench machine for grinding lens edges by hand on three wheels of different grit. The LY-316 has 180#, 280# and 400# wheels, so coarse grinding, fine grinding and the finishing edge are done in one place.
Can the LY-316 grind polycarbonate (PC) lenses?
Yes. Order it with a custom PC wheel, which cuts polycarbonate cleanly instead of smearing it. Tell us which lenses you edge and we confirm the wheel set on your quotation.
Which wheel do I use for what?
Use the 180# wheel to take off material, the 280# wheel to refine the edge and the 400# wheel to finish it.
Does it need a water connection?
No. The LY-316 has its own 900 mL water tank with a tap that feeds the wheels.
LY-316 or CP-7A-35WV?
Choose the LY-316 for three separate wheels, an LED lamp, a cooling fan and the option of a PC wheel. Choose the CP-7A-35WV for a single compact diamond wheel with coarse and fine zones and a V-groove.
How big is it?
The LY-316 measures 350 × 220 × 250 mm (L × W × H). Its rated power is 120 W.
