DIAMOND TURNING The II-VI Diamond Turning facility was established in 1988 with the purchase of a Pneumo MSG500 flycutter. Today, we are an industry leader in diamond-turned components for commercial industry, military, and aerospace customers. Our facility is recognized as one of the largest and most advanced in the world, offering: • • • • • • • Flycutting of plano and cylindrical optics Two-axis turning—up to 700mm-diameter capacity Fast Tool Servo for non-rotationally symmetric geometries Slow Tool Servo for extended range, non-rotationally symmetric geometries 4-axis turning - up to 700mm-diameter...

DIAMOND TURNING CAPABILITIES SINGLE-AXIS FLYCUTTING II-VI uses single-point diamond flycutting machines with CNC controllers capable of producing high-volume plano (flat) geometries. We have the capability to produce surface finishes on OFHC copper of less than 50 Angstroms RMS, surface finishes on 6061 aluminum of less than 60 Angstroms RMS, and figure accuracies of λ/4 peak-tovalley at 0.6328µm on both materials. Products include: • • • • • • • • Prototype and high-volume products Laser beam delivery mirrors Laser cavity mirrors Steering and head mirrors for military/aerospace Deformable mirrors...

FREEFORM TURNING Non-rotationally symmetric geometries are now possible through the utilization of fast and slow tool servo technologies. FAST TOOL SERVO (FTS) Up to 70µm of departure from rotational symmetry can be realized using a piezoelectric fast-tool device. Fast tool servo processes are capable of producing RMS surface roughness less than 50 angstroms and figure accuracy less than 0.2µm peak-to-valley. SLOW TOOL SERVO (STS) For non-rotational symmetry greater than 70µm, slow tool servo technology is applicable. Components with departure of 3mm have been successfully diamond turned at II-VI....

DIAMOND TURNING CAPABILITIES FOUR-AXIS TURNING The ever-changing needs of optical designers requires technology that can keep up with this evolution. II-VI’s 4-axis diamond turning machining incorporates B-axis freedom to expand our capabilities into brand new arenas. This lathe can support parts up to 700mm (28 inches) in diameter. The hydrostatic oil bearing B-axis incorporates a rotary action orthogonal to the X-Z plane with a range up to 350mm in diameter. This technology permits tool-normal manufacturing for steep radii and can be coupled with our Fast Tool and Slow Tool Servo technologies...
