The advanced decentration and blocking system
 Latest generation of fully automatic lens decentration and blocking system
The requirements from the optician or optical lab has changed significantly over recent years and Weco has responded to this demand by developing and producing the CAD 5 system.
With many features designed to simplify the lens measurement, decentration and blocking processes more than ever before, the CAD 5 offers class-leading functionality at a surprisingly affordanle price.
Backwards compatible with many of the existing Weco edging systems the CAD 5 also offers exciting upgrade possibilities, allowing existing users of the"industry standard" Weco 450 Drill edger to benefit from its many features.
The CAD 5 is a fully automatic device that does not require human input during its centering and blocking operations. An integrated lens measurement systems eliminates the need for a lensmeter for single vision lenses, thereby reducing the possibility of operator-induced errors.
Optical Trace Function
For rimless or Supra lenses the CAD 5 will produce an optical image of the lens, allowing the shape to be "traced" without the use of a conventional tracer. At the same time the rimless hole co-ordinates are plotted and stored all in an extremely quick operating time of 12 seconds. Less mechanical distortion ensures that shape reproduction is significantly improved.
- Optical Trace for perfect shape measurement and location of drill holes or slots
- Fast operating time of 12 seconds
- Holes can be adjusted manually and the operator can add, move or remove holes or slots
- Adjustable hole diameter
- Accurate
Modifier Function
Shape modification for rimless lenses is becoming more popular and this is easily accomplished with the CAD 5. Several programs are available to make an adjustment to:
- Half-height (lowest part of the lens) for progressive lenses
- Height only
- Width only
- Height with width adaptation
- Width with height adaptation
- Circumference radius length
Centering
Lens centration is conducted automatically using the integrated lens power measurement system. When processing a single vision lens the CAD 5 performs a lens analysis to detect the optical centre and axis identification. For bifocal lenses the lens image analysis is performed by determining the near vision segment. Progressive lenses are processed by identification of the progressive markings.
- Centering of any type of lens possible
- Quick and easy indentification of centering reference points
- Automatic recognition of printings
- Comparison of lens diameter to the requested shape
Blocking
Once the lens has been automatically centered the block is applied automatically by the integrated blcoking unit. Blocks are held magnetically to ensure the block is held securely before it is attached to the lens with high accuracy. Less operator steps means fewer errors and a reduction of expensive wasted lenses.
