The ingots and wafers are already cut. It's how many parts come off the grinder per shift, and how many of those parts are within spec on the first pass.<\/p>\n <p>Two numbers set that. First, cycle time per face. A typical \u00d8 40 mm germanium lens with 0.5 mm single-side allowance grinds in 40\u201350 seconds on the G-100; double-sided that's about 90 seconds plus chucking. At 60% utilization across an 8-hour shift, a single G-100 puts out 200\u2013300 lenses. Second, first-pass yield. The G-100 holds form within 0.005 mm and chipping under 0.2 mm; that's enough margin that the downstream centering and polishing stages don't reject material back upstream.<\/p>\n <p>Where the G-100 infrared optics grinding machine earns its keep against a general-purpose CNC freeform grinder is the same place it earns it against an outsourced grinding service: spherical work doesn't need CNC freeform's feature set, and outsourcing trades cycle time for lead time. For the surface-finish theory and grinding-to-polishing handoff details, see our <a href=\"https:\/\/www.opticalcutting.com\/germanium-lens-grinding\/\">germanium lens grinding<\/a> process page.<\/p>\n <\/div>\n <\/div>\n<\/section>\n\n\n<section>\n <div class=\"wrap twocol\">\n <div class=\"lab\"><div class=\"eyebrow\">How it grinds<\/div><h2>Spherical generation, plus the bits everyone forgets to spec<\/h2><\/div>\n <div>\n <h3>One spindle for three surface types<\/h3>\n <p>Tilt the wheel cup, change the program \u2014 the same chuck and spindle generate convex, concave, or flat surfaces on the same lens blank if you need both faces of a meniscus. The wheel itself is a 350\u2013400 grit electroplated nickel-bond cup on a #45 steel base; we ship the G-100 with one wheel for each common grit, and a wheel change is under five minutes once the spindle is calibrated.<\/p>\n <h3>Centering before grinding, not after<\/h3>\n <p>The integrated centroscope is what makes the \u2264 20\u2033 centering tolerance achievable. Drop the blank in the chuck, swing the centroscope into the optical path, dial the chuck until the optical axis pin sits steady on the reticle, lock it down. Now the spherical generation cycle has a true optical-axis reference, not a mechanical OD reference. Decenter on the finished part is bounded by how well you set the centroscope, not how round the blank's OD was.<\/p>\n <div class=\"note warn\"><div class=\"t\">\u26a0 Spec gotcha \u2014 backlash compensation<\/div><p>The G-100 doesn't run backlash compensation in software, because the servo drives a direct ball screw without a gear backlash to compensate. New customers who ask for backlash compensation as a spec line are usually carrying it over from a stepper-driven machine. On servo-driven ball screws like this one, the relevant spec is repeatability (\u00b10.003 mm here), not backlash. Worth flagging before the spec sheet comes back marked \"no\" and somebody worries.<\/p><\/div>\n <\/div>\n <\/div>\n<\/section>\n\n\n<section class=\"band\">\n <div class=\"wrap twocol\">\n <div class=\"lab\"><div class=\"eyebrow\">Comparison<\/div><h2>How does a dedicated spherical grinder compare to CNC freeform and outsourcing?<\/h2><\/div>\n <div>\n <p>Most small-aperture IR work is spherical or near-spherical. A dedicated infrared optics grinding machine like the G-100 handles that natively. A full CNC freeform grinder will do the job too, but it's optimized for aspherics and freeform optics \u2014 features you pay for and don't use. Outsourcing trades cycle time for lead time. Here's how the three approaches compare on a typical \u00d8 40 mm Ge production run.<\/p>\n <table class=\"tbl\">\n <thead><tr><th>Approach<\/th><th>Cycle \/ face<\/th><th>Form tolerance<\/th><th>Setup & training<\/th><th>Lead time<\/th><\/tr><\/thead>\n <tbody>\n <tr><td>Full CNC freeform grinder<\/td><td>90\u2013120 sec<\/td><td>tight (overkill)<\/td><td>CNC programmer needed<\/td><td>days<\/td><\/tr>\n <tr><td>Outsourced grinding<\/td><td>n\/a<\/td><td>varies by vendor<\/td><td>none (drawing handoff)<\/td><td>2\u20136 weeks<\/td><\/tr>\n <tr><td class=\"hl\">G-100 dedicated spherical<\/td><td class=\"hl\">40\u201350 sec<\/td><td class=\"hl\">\u00b10.005 mm form<\/td><td class=\"hl\">PLC + handheld, one shift<\/td><td class=\"hl\">in-house<\/td><\/tr>\n <\/tbody>\n <\/table>\n <p>The G-100 wins on cycle time on its native job (spherical, small-aperture IR) and loses to a CNC freeform machine if you also need aspherics on the same machine.

The ingots and wafers are already cut. It's how many parts come off the grinder per shift, and how many of those parts are within spec on the first pass.<\/p>\n <p>Two numbers set that. First, cycle time per face. A typical \u00d8 40 mm germanium lens with 0.5 mm single-side allowance grinds in 40\u201350 seconds on the G-100; double-sided that's about 90 seconds plus chucking. At 60% utilization across an 8-hour shift, a single G-100 puts out 200\u2013300 lenses. Second, first-pass yield. The G-100 holds form within 0.005 mm and chipping under 0.2 mm; that's enough margin that the downstream centering and polishing stages don't reject material back upstream.<\/p>\n <p>Where the G-100 infrared optics grinding machine earns its keep against a general-purpose CNC freeform grinder is the same place it earns it against an outsourced grinding service: spherical work doesn't need CNC freeform's feature set, and outsourcing trades cycle time for lead time. For the surface-finish theory and grinding-to-polishing handoff details, see our <a href=\"https:\/\/www.opticalcutting.com\/germanium-lens-grinding\/\">germanium lens grinding<\/a> process page.<\/p>\n <\/div>\n <\/div>\n<\/section>\n\n\n<section>\n <div class=\"wrap twocol\">\n <div class=\"lab\"><div class=\"eyebrow\">How it grinds<\/div><h2>Spherical generation, plus the bits everyone forgets to spec<\/h2><\/div>\n <div>\n <h3>One spindle for three surface types<\/h3>\n <p>Tilt the wheel cup, change the program \u2014 the same chuck and spindle generate convex, concave, or flat surfaces on the same lens blank if you need both faces of a meniscus. The wheel itself is a 350\u2013400 grit electroplated nickel-bond cup on a #45 steel base; we ship the G-100 with one wheel for each common grit, and a wheel change is under five minutes once the spindle is calibrated.<\/p>\n <h3>Centering before grinding, not after<\/h3>\n <p>The integrated centroscope is what makes the \u2264 20\u2033 centering tolerance achievable. Drop the blank in the chuck, swing the centroscope into the optical path, dial the chuck until the optical axis pin sits steady on the reticle, lock it down. Now the spherical generation cycle has a true optical-axis reference, not a mechanical OD reference. Decenter on the finished part is bounded by how well you set the centroscope, not how round the blank's OD was.<\/p>\n <div class=\"note warn\"><div class=\"t\">\u26a0 Spec gotcha \u2014 backlash compensation<\/div><p>The G-100 doesn't run backlash compensation in software, because the servo drives a direct ball screw without a gear backlash to compensate. New customers who ask for backlash compensation as a spec line are usually carrying it over from a stepper-driven machine. On servo-driven ball screws like this one, the relevant spec is repeatability (\u00b10.003 mm here), not backlash. Worth flagging before the spec sheet comes back marked \"no\" and somebody worries.<\/p><\/div>\n <\/div>\n <\/div>\n<\/section>\n\n\n<section class=\"band\">\n <div class=\"wrap twocol\">\n <div class=\"lab\"><div class=\"eyebrow\">Comparison<\/div><h2>How does a dedicated spherical grinder compare to CNC freeform and outsourcing?<\/h2><\/div>\n <div>\n <p>Most small-aperture IR work is spherical or near-spherical. A dedicated infrared optics grinding machine like the G-100 handles that natively. A full CNC freeform grinder will do the job too, but it's optimized for aspherics and freeform optics \u2014 features you pay for and don't use. Outsourcing trades cycle time for lead time.
