MonoSpheraRX – DD, the real all in one industrial edger

	Vertical and inclined rimless, with polishing, safety bevelling, holes and slots.
	Vertical and inclined groove, with polishing, and safety bevelling.
	Inclined T bevel and inclined step back, without safety bevelling.
	Vertical and inclined V bevel, with safety bevelling on back surface.
	Step milling process under the edge for reduction of edge thickness and allow thick prescription lenses to fit in wrap sport frames studied for thin plano lenses.
	Import and design of free form frames with no limits to the shapes and the number of operation. Polishing of complex shapes with the ability to jump the shape parts with small radius that cannot be polished because of the polishing tool diameter.

Why to chose MonospheraRX-DD?

Production rate

Thanks to the milling technology the cutting process is fast due to the method to cut away the excess part of the lens. The automatic loading system allow also to reduce the downtime of the cutting process. You can automate your glazing department, connecting the edger with a stack loader or a convey belt. More production in the same time means more business.

Flexibility

The milling technology and the 4 axes allow the machine to perform any kind of shape with any angle. Also the step back or high base (up to base 16!) in some sport lenses is not a problem. The machine is equipped with a range of tools that ensure any kind of working process (see the workable edge types). The opportunity to perform also special edge types normally enable the lab to get more work increasing the business.

Reducing manpower costs

Connecting with a convey belt (or stack loader), all the jobs through smoothly in the cutting process. Control or supervision are not required and a single worker can manage more machines. The operators have just to focus in to feed the edger. Let get you surprised by the through-put of the MEI edger.

Easy to use

The traditional shape can be performed just calling the job (digit the number or reading the bar code). The operator is trained to drawn any sport and fashion lenses with Tecnocam software. It’s no longer the time of skilled workers that work manually special edge.

No obsolescence

The frame of the machines allow any software and tools updating. In this way the lab can use always the last version of the edge. In case the future eyewear requirement asked new edge types won’t be necessary to change the edger (with new investment) but updating software and some part of the hardware the edger will be able to perform new solution. Besides, the industrial structure of the edger grant a long life time. Just try to set a long-term strategy in your business.

Accuracy

The milling process and the measurement feeler allow to arise the higher accuracy of the finishing. The complete automatic cutting process grant the perfect mirroring of both lenses. No manual working are required, thus the quality don't lay it on the line. You can deliver your job without any matter of concern!

Reducing waste products

The mirroring help you to perform two perfectly identical lenses. Besides the milling process, using a tenth of force on the lens compared with grinding process, and the Double Drive allow to work any hydrophobic lenses without any risk to rotate them or damage the coated surface (also without protection tape). Finally it’s a save of money that affect the bottom line of your business.

Reducing in maintenance costs

The industrial structure of the machine needn’t so much assistance and maintenance. The operator is trained to replace the material subject to wear by himself; and the costs of the tools is cheap. Almost all those requirements of the clients are solved by phone or remote control. Besides, thanks at the dry cutting process the water consumption is minimum. All these features reduce remarkably the maintenance costs. Currently how much do you pay for that?

Compatible with any devices

All our edger use standard OMA protocol. OMA language is worldwide used in ophthalmic field so the edge software is open to be interfaced with any devises or lab software management. In this way our clients can install our machine without to worry about the present and future configuration of their labs. It means no need to replace devices just bought.

Mini Stack loader for Loh trays 15+15 position

This device, increase the autonomy of the machine. Thanks to a stack managing system, give the possibility to load 15 trays, and to run it automatically if they have a properly barcode and the cutting information stored into the machine or into your server. The working area is inside the main structure of the machine, so no outside space is needed whit this device, as the attached lay out shows. A door permit to accede to this stack loader area, where two different tray stacks (15 position for the loading and 15 position for the unloading) provides the autonomy.
