BEFORE USE, READ THIS MANUAL. This operator’s manual includes operating procedures, safety precautions and specifications for the NIDEK PATTERNLESS EDGER, Lex 1000. IEC standards are applied in this manual. Cautions for safety and operating procedures must be thoroughly understood before using this instrument.
Page 4 Use precautions Before Use WARNING • Use a hand cart to move the instrument to a different location. At least two persons are necessary to lift the instrument. Back injury or stumbling may occur when a single person attendts to move the instru- ment.
Page 5 • Do not place heavy objects on the cord. CAUTION A damaged power cord may cause fire or electric shock. • Do not yank the power cord to disconnect it from an outlet. This can damage the metal core of the cord and may result in short circuit or electric shock.
Page 6 During Use • Never touch the wheel when it is rotating. WARNING It may result in injury. • Never open the processing chamber door during lens processing. Spray containing processing waste may cause eye damage. • Be sure to use this instrument only to process lenses for glasses. The instrument can not be substituted for a grinder.
Page 7 • The processing chamber door automatically opens and closes. Be sure to keep face CAUTION or hands clear. Be careful not to catch figers with the door to being closed. • Do not apply too much pressure on the stylus of the tracing unit. The stylus is easy to bend or break.
Page 8 Maintenance and Check • Be sure to perform check before and after use. It is recommended to have periodic CAUTION checks every two years. Periodic checks must be performed by qualified personnel. Contact NIDEK or your authorized distributor. Wheels must be also replaced by qualified personnel. Do not replace the parts other than fuses and the stocking filter nor disassemble the instrument.

Page 87: Other Processing
OPERATING PROCEDURES: Other Processing Other Processing 2.9.1 Processing for frame changing This function is used to mount eyeglass lenses in use into other frames. In frame changing mode, a lens shape can be compared with a frame shape to confirm whether the lens size is sufficient or not.
Page 88 OPERATING PROCEDURES: Other Processing Block a lens with a pliable cup. 1) Mark the lens at the optical center and points in the horizontal direction with a lensmeter before removing lenses from frames. 2) Remove the lenses from the frames. 3) Block the optical center on the convex surface of the lens with a pliable cup using a centering device.
Page 89 When pressing the FC button to go into frame changing mode, simple frame changing mode is automatically activated. The lens and frame shapes do not need to be overlaid in the Lex 1000 as the Ice 1000 or ICE-9000 has already confirmed that the lens size is sufficient.
Page 90: Polishing
OPERATING PROCEDURES: Other Processing 2.9.2 Polishing This is the mode to polish a lens edge after processing. It saves the effort of buffing to the minimum. Press the Polish button and select “Polish” before processing starts by pressing the button. The indication in the Polish field changes to Polish.
Page 91: Safety Beveling
OPERATING PROCEDURES: Other Processing 2.9.3 Safety beveling Lenses can be safety-beveled before processing is completed. Press the button to activate safety bev- eling before processing starts by pressing button. The LED of the button lights up and the image of processing shape for current set- tings on the layout screen changes to the safety-beveled one.
Page 92 OPERATING PROCEDURES: Other Processing 3) Press the button. Safety beveling is performed. When the Edge box is also checked, safety beveling starts after retouching. • When the lens is safety-beveled in first processing, the safety bevel can be retouched in the same manner.
Page 93: Soft Processing
OPERATING PROCEDURES: Other Processing 2.9.4 Soft processing Soft processing is the method to control the rough- ing process more precisely. The processing time may increase slightly but the processing noise is reduced as is the axis shift dur- ing processing. For processing lenses whose coating is slippery, turn on soft processing to reduce the axis shift due to slippage.
Page 94: Tilting
After lens shape measurement, the screen changes to the guided processing screen and the Lex 1000 pauses. Steps 1 to 4 of 2.7.2 Guided processing (see page 47), steps 1 to 4 of 2.8.4 Guided grooving (see page 65) Adjust the bevel or groove.
Page 95 OPERATING PROCEDURES: Other Processing 3) Move the highlight ( ) to the Bevel Curve or Groove Curve numeric field with the button. 4) Set the desired curve value with the button. An A attached to the curve values indicates the bevel (or groove) position is calculated from Ratio. The absence of an A indicates the bevel (or groove) position is calculated from the spherical curve of the lens.
Page 96 Then the Lex 1000 goes into guide processing mode automatically. The figure to the right is the side view of tilting an EX lens. As illustrated, the...
Page 97 OPERATING PROCEDURES: Other Processing While doing so, always observe the bevel (or groove) at the boundary between the far-vision and and near-vision parts. In most cases, the edge’s thinnest position is at the boundary. Adjust the tilt amount so that one side of the bevel (or groove) remains just within the lens edge. Explanations about adjustment in each position are as follows: To restart the operation from the beginning, reset the tilt and position fields to 0.0 and set the curve field to auto.
Page 98: Drilling (Only When The Lex Drill Is Connected)
In combination with the Ice 1000 Read the JOB No. barcode with the barcode scanner (optional). Set the right-eye lens in the Lex 1000 and process it. [Lex 1000] Confirm that the color of the ring of the drill bit set in the Lex Drill is the same as that in the upper right corner of the Drill indication on the layout screen of the Lex 1000.
Page 99 Drill the left-eye lens in the same manner as steps 3 to 6. • The left-eye lens can be processed while the right-eye lens is drilled in the Lex Drill. • Importing other data to the Lex 1000 prevents the lens from being retouched both for edging and drilling.
Page 100: Retouching For Drilling
The All field to the right is highlighted. • Retouching for drilling can not be selected at the same time as retouching for edging, grooving, or safety beveling in the Lex 1000. Select “All” or “Repair” with the button. [Lex 1000] All: All holes are drilled again.
Page 101: Hole Edit (In Retouching)
Lenses can be drilled again after minor changes to the hole specifications such as position. • Hole edit in the Lex 1000 is only for moving the hole position within ± 1 mm or changing the hole diameter and depth.
Page 102 OPERATING PROCEDURES: Drilling (only when the Lex Drill is connected) Change the hole position, depth or diameter of the desired holes in the same manner as steps 2 to 5 and press the button again. The LED (right side) blinks when the lens to be retouched is the right side and the LED (left side) blinks when the lens to be retouched is the left side.
Page 103: Hole Edit (Before Drilling)
Lenses can be drilled after minor changes to the hole specifications such as position of the imported JOB data. • Hole edit in the Lex 1000 is only for moving the hole position within ± 1 mm or changing the hole diameter and depth.
Page 104 OPERATING PROCEDURES: Drilling (only when the Lex Drill is connected) To change the hole diameter, move the highlight to the hole diameter numeric field with button and change the value with the button. To change the hole depth, move the highlight to the hole depth numeric field with the button and change the value with the button.
