Diamond Turning Tools for Infrared Industry are precision single-crystal diamond cutting tools engineered specifically for machining infrared optical materials. These tools enable ultra-precision machining of components used in thermal imaging, night vision, and infrared optical systems, delivering mirror-quality surfaces with minimal sub-surface damage.
Diamond Turning Tools for Infrared Industry are precision single-crystal diamond cutting tools engineered specifically for machining infrared optical materials. These tools enable ultra-precision machining of components used in thermal imaging, night vision, and infrared optical systems, delivering mirror-quality surfaces with minimal sub-surface damage.
Manufactured from high-purity natural or synthetic diamond, these tools feature specialized geometries optimized for brittle infrared materials, ensuring superior surface finish and extended tool life compared to conventional cutting tools.
Diamond Turning Tools for Infrared Industry are engineered specifically for machining infrared materials such as germanium (Ge), silicon (Si), zinc selenide (ZnSe), and chalcogenide glass.
Our single crystal diamond turning tools are engineered with a precise negative rake angle and a finely controlled edge radius to support the machining of brittle infrared materials such as germanium (Ge), silicon (Si), zinc selenide (ZnSe), and chalcogenide glass. This optimized geometry helps reduce micro-chipping, edge breakage, and subsurface damage during ultra-precision cutting.
With an ultra-sharp cutting edge and excellent profile accuracy, our tools help achieve mirror-grade surface finishes on infrared optical components. The cutting result is smooth and stable, making the tools ideal for infrared lenses, windows, and sensor-related optical parts where surface quality is critical.
For aluminum, copper, and other non-ferrous parts used in infrared assemblies, we also offer tool configurations with a 0° rake angle and optimized edge radius. This ensures stable cutting performance and high machining accuracy for structural parts, cooling housings, and supporting components.
Our diamond turning tools are widely used in the production of infrared optical components, including:
· Lens Types: Aspheric, spherical, diffractive, Fresnel, and hybrid lenses
· Components: Infrared windows, sensors, and optical elements for SWIR, MWIR, and LWIR systems
· Materials Processed: Germanium (Ge), Silicon (Si), Zinc Selenide (ZnSe), Zinc Sulfide (ZnS, multispectral), Chalcogenide Glass, Calcium Fluoride (CaF₂), Gallium Arsenide (GaAs)
· Mirrors: Off-axis parabolic, elliptical, and freeform mirrors
· Housings: Precision cooling housings and structural parts for IR assemblies
Our diamond turning tools are designed for use with ultra-precision single-point diamond lathes, including:
· Moore Nanotech systems (250 UPL, 350 UPL, 650 FG)
· Precitech Nanoform series
· LT Ultra precision machines

LTCT Diamond Tools offers complete customization to meet any unique machining requirement. Whatever your application demands, please consult with us—we have the capability to manufacture the exact tool you need.
First-class Natural Diamond (ND) and Advanced Synthetic Diamond, both available, Litian Century has the State-of-the-art equipment for both producing and measuring our diamond tools.
Our technicians have been working with diamond for more than 20 years now. We are constantly innovating and driving the company years ahead of the competition. is the essential for perfect performance and durability of our Single crystal diamond turning tools. You can choose the suitable material according to your requirements. Take advantage of our innovations that will assure you are using the most efficient and reliable tools that eliminate errors and reduce production costs.
Single crystal diamond provides outstanding hardness and wear resistance, delivering a much longer tool life in precision machining of Si and Ge compared with conventional cutting tools.
The atomic-level sharpness of the cutting edge helps maintain excellent surface integrity, reducing striations, tearing, and other defects on infrared optical surfaces.
The low chemical affinity between diamond and many infrared materials helps minimize built-up edge and material adhesion, supporting more stable and consistent machining results.
Even under demanding cutting conditions, the tool edge remains sharp and stable, which is especially important for materials that are sensitive to heat, pressure, and edge wear.
· Edge Radius: R0.1 mm to R10.0 mm, with laser-verified tolerance of ±0.02 mm
· Rake Angle: -45° to 0°, depending on the material and cutting requirement
· Clearance Angle: 10°–15°, helping prevent rubbing and improving cutting efficiency
· Included Angle: 30°–60°, balancing edge strength and penetration performance
Tool Clamping
· Handle the tool lightly when clamping
· Do not contact the diamond tip directly
· After removing the Diamond Turning Tool, place it back in the tool box immediately
· Do not leave tools exposed to avoid damaging the diamond
Tool Cleaning
· Wipe the diamond tips gently with a clean foam stick dipped in industrial alcohol
· Avoid excessive force or abrasive materials that could damage the cutting edge
