Automatic edge grinding process

Fully automatic edge grinding process:

(1) Adjustment before processing and determination of lens processing standards

(2)Scan

1. Select Binocular Scan, Right Eye Scan or Left Eye Scan. If the symmetry of the frame is not good, choose right eye scanning or left eye scanning; if the symmetry of the frame is good, choose binocular scanning.

2. Select the frame type (metal frame or plastic frame), select the resin lens type, and select the sharp edge type (normal sharp edge, forced sharp edge, flat edge).

3. Place the frame face down into the scanning box and secure it with the frame clip. If it is rimless glasses or half-rim glasses, first place the support plate (or template) horizontally on the middle instrument, install the suction cup, and then install it on the scanning accessory. Then, place the accessory into the scanning box and insert the scanning rod.

4. Press the scan cycle start button to scan the frame or support plate (or template).

(3) Middle parts positioning

Align the horizontal processing reference lines of the left and right gradient multifocal lenses with the horizontal center line of the dial, and position the "cross" in the middle position of the center instrument. Installing and removing suction cups. In order to protect the surface of coated lenses and resin lenses from damage, special plastic protective films should be applied to both sides of the lenses and adhesive sheets should be used

(4)Edging

1. Select the sharp edge type: regular sharp edge, forced sharp edge or grinding edge.

2. First make a suitable lens, place it on the lens holder of the edger and clamp it (pay attention to the direction of the suction cup point). Enter the distance and height of the far pupil of the right eye and start edging. If you scan the binocular lens circle, the computer will automatically calculate and display the FPD value. If you scan the support plate (or template, single piece), you also need to enter the FPD value.

3.Edging machineThe scanning probe scans and tests the front and rear surfaces of the right lens according to the shape of the template. If the diameter of the lens meets the requirements of the mirror ring shape and size, and if the forced sharp edge mode is not selected in advance, it will continue to work until it is formed.

4. Take out the lens (do not remove the suction cup) and try to install the frame. Compare it to a frame (compare rimless glasses to a template). If it does not meet the requirements, modify the grinding amount and re-grind the edges (only the sharp edges or flat edges are sharpened at this time) until the size is appropriate.

5. After grinding the lens of the right eye, follow the above method to grind the lens of the left eye.

(5) Secondly, grind the safety angle, polish, assemble, adjust (shape), process, and test.
