Ø5–80 mm; stated cycle 18–40 s
The manually loaded machine provides rough and fine grinding with profile-copying capability. It suits applications where the operator handles loading and the mix of parts does not justify automatic tray handling. Compare the fixture, reference template and wheel arrangement using the actual part outline. A quoted cycle does not include every loading, cleaning and inspection task in the production cell.

Automatic pick-and-place connects the blank and finished trays. Round parts use a different sizing approach from shaped parts that follow a profile template. The published 0.01 mm feed precision and ≤0.006 mm dual-axis run-out describe different machine characteristics; neither should be presented as a universal guarantee of finished lens decentration. Evaluate them against the agreed finished-part inspection method.

Ø30–220 mm; 2D / 2.5D flat parts
Include this station when the requirement is a polished edge on a flat technical component. It is a related finishing operation, rather than a third lens edger. The stacked-part fixture and CAD outline workflow can be paired with AL-7S loading. The decision depends on incoming edge condition and the required finish, not only on the outside dimensions.
View specifications →This optical lens edging machine range serves precision optics and technical components. It is not intended for architectural glass, mirrors or ophthalmic Rx laboratories. The distinction matters because a spectacle-lens finishing system, a building-glass edge line and a precision-optics profile grinder serve different materials, drawings and production methods.
Send the finished outline, blank dimensions, thickness and edge detail. Include chamfers, corner conditions and any feature that changes the way the part can be held. For non-round parts, a stated diameter range alone is insufficient: the diagonal, fixture envelope and tool access also need checking. The machine proposal should explain how the component will be located and restrained.
Describe the incoming surface condition as well. A polished optical face may need different contact protection from a rough blank. Workholding, loading and cleaning must preserve the surfaces already completed upstream. The best equipment choice is the one that meets the complete finished-part requirement, not simply the one that removes the edge fastest.
A manually loaded optical lens edging machine gives the operator direct control over part placement and is useful when the part mix changes. EG-80 provides the core rough-and-fine grinding operation with manual handling. The labor requirement includes loading, unloading, cleaning and checking parts, so the machine cycle is only one part of the production calculation.
Auto-EG-80 adds tray handling and automatic pick-and-place. This becomes more relevant as repeated batches increase, but it also requires an agreed tray layout and a reliable incoming condition. Check whether different lens thicknesses, part orientations or protective requirements affect the handling process. Automatic loading should reduce manual work without making changeovers unnecessarily complicated.
Compare both configurations using the same drawing, incoming stock and inspection criteria. Record accepted parts per shift as well as the nominal cycle. The published cycle ranges are model references, not a guarantee for every part. A production comparison should include wheel condition, fixture change, loading interruptions and any required inspection between batches.
An optical lens edging machine controls an outside profile, but optical centering is a separate requirement involving the relationship between mechanical geometry and the optical axis. A tight spindle run-out specification does not, by itself, establish the finished lens’s centering accuracy. State how centering will be set and measured.
Every optical lens edging machine in this range clamps the lens between bells and lets it settle onto its own optical axis before the wheel comes in, so centring is a requirement to specify rather than a separate class of machine. Where centring governs and the parts are round, discuss the EG-120L and the EG-185L. The documented upper diameter envelopes are 120 mm and 185 mm. Centring capability here is a setting made on a centroscope, not an automatic closed-loop record for every finished piece. Agree the measurement procedure during selection.
EP-220C belongs to another operation: polishing edges of suitable 2D and 2.5D flat components, including stacked work. Its process should not be described as the same operation as outside-diameter grinding. For a complete route, first define the edge shape, then the required surface finish, and finally the method used to check the finished component.
An optical lens edging machine project should identify the material by grade and condition, not only by a broad label such as glass or crystal. Provide the blank dimensions, the surfaces already completed and any restriction on contact with the workpiece. The selected machine, tool and process media need to be reviewed as a combination. A capability demonstrated on one model must not be assumed for every machine in the range.
Optical glass, fused silica, crystalline quartz, sapphire, germanium and technical ceramics present different processing requirements. The website’s range covers multiple applications, but that does not mean each station is a universal material-processing machine. For a model without a documented material list, ask for application review and representative sample machining before treating compatibility as established.
Discuss coolant or slurry handling, cleaning and the condition needed by the next operation. The trial should use representative stock rather than an unusually easy sample. If part families differ substantially in thickness, geometry or incoming damage, identify those differences in the request so the proposed configuration can be assessed against the real production mix.
Use a trial to assess the proposed optical lens edging machine configuration against a defined part and acceptance method. Send a drawing, representative blanks and the material specification. Agree the output measurements before the trial starts, including which surface or feature will be checked and how the sample will be referenced during inspection.
Free sample machining is available for machining applications, including cutting, grinding and polishing. Inspection and handling equipment instead require evaluation against the relevant measurement or transfer task. Agree the sample quantity, evaluation scope and arrangements with the team. Trial results describe the tested combination of material, tooling, settings and geometry; they should not be generalized to unrelated parts.
Record more than the successful final sample. Note the incoming condition, tooling, processing sequence and any setup or adjustment needed. Where output rate matters, distinguish machine processing time from loading, cleaning and inspection time. These records help establish a production proposal and give the operator a useful starting point during installation and training.
A useful optical lens edging machine quotation links each requested outcome to a configuration and an inspection procedure. List the part family, required geometry, output criteria and production objective. Identify which items are machine specifications and which are sample-part acceptance values. This prevents a spindle or probe specification from being mistaken for the guaranteed result on every finished workpiece.
Ask for the proposed machine sequence, workholding approach and loading method. Review access for changing tooling and cleaning, along with the space needed for incoming and finished parts. Site requirements should be confirmed for the ordered configuration rather than copied from another model’s utility information. Put responsibilities for installation, training and acceptance into the order documentation.
Vimfun’s documented support terms include a 12-month warranty from final acceptance and continuing spare-parts support. Confirm the applicable service scope and response arrangements in the quotation. Before shipment, agree which checks will be performed, which records will accompany the machine and what the customer must prepare for commissioning.
To specify an optical lens edging machine, send the finished drawing together with a description of the incoming blank. State whether you are replacing an existing machine, removing a production bottleneck or planning a new cell. These are different purchasing problems even when the final component is the same.
Include material grade, minimum and maximum dimensions, relevant optical and mechanical tolerances, batch size and expected annual quantity. Describe how parts arrive at the station and how they need to leave it. If an existing fixture, tray or basket must be retained, include its dimensions and photographs. Mark any drawing requirements that have not yet been finalized.
For an existing process, explain the current difficulty in observable terms: frequent manual adjustment, inconsistent incoming thickness, handling damage, long changeovers or an unbalanced sequence. This is more useful than requesting the fastest machine without a defined task. We can then compare the suitable equipment families and explain the trade-offs in the proposal.
Start with the part geometry, material and incoming condition, then agree the output and inspection method. A defined outside profile and edge condition, with optical centering assessed separately where required. The application team can compare suitable model families once those requirements are clear.
No. The machine process and final acceptance checks have different roles. In-process measurements can support control of a selected operation, but the finished component still needs the checks agreed on its drawing and in the acceptance procedure.
No. Material suitability depends on the documented model, tooling, workholding and process conditions. Review the material grade and representative blanks with the application team. A family-level overview helps find candidates; it does not replace the specification and evaluation of the selected machine.
Yes. A single-station proposal should still define the incoming and outgoing condition. Provide the equipment or process used immediately before and after it so the new station can be selected for the actual production route.
Workpiece geometry and range, loading method, measurement functions, tooling, fixtures and the agreed installation scope all affect the proposal. Request a configuration against a drawing instead of comparing prices for machines that may perform different tasks.
