To keep up with the fast‑changing needs of the electro‑optics industry, LTCT has developed a complete line of high‑performance diamond tools. Each tool is made from top‑grade natural single‑crystal diamond, shaped with advanced grinding techniques and verified by precision geometric measurement. Every cutting edge is inspected under 800× magnification to ensure it’s completely defect‑free—a level of quality that makes nanometer‑level surface finish possible. We use only flawless diamonds, which means longer tool life and far less risk of edge chipping or cracking.

What makes these tools special?
An ultra‑precision single‑point diamond turning tool uses a single‑crystal diamond as its cutting edge for machining at the highest precision levels. The nose radius can be tailored anywhere from 0.001 mm to 100 mm, and the form accuracy can reach better than 0.03 μm. Geometric details are designed flexibly to meet specific application needs.
Where they’re used?
These tools are mainly for ultra‑precision turning of non‑ferrous metals and polymers. They deliver mirror‑like finishes, giving work pieces outstanding dimensional accuracy and surface smoothness. They’re especially vital for creating micro‑structured surfaces—think diffractive optics, Fresnel structures, and lens arrays.
Machinable Materials
Our single point diamond turning tools efficiently machine the following materials:
l Non-Ferrous Metals: Copper, Aluminum and their alloys, Electrolytic Nickel, Electroless Nickel etc.
l Polymers: PMMA, Polycarbonate etc.
l Others: Brass, Gold, Plastics etc.
Application Fields
l Mobile 3C Products (Consumer Electronics)
Manufacturing of ultra-precision lens molds for smartphone cameras. The resolution and imaging quality of camera lenses are directly determined by mold accuracy. As smartphone camera resolutions continue to increase, our tools meet the most demanding mold specifications.
l Smart Home & New Energy Vehicles
Vehicle Cameras: High-precision optical lens molds for advanced driver-assistance systems (ADAS)
LED Lighting Systems: Automotive lens molds, reflector molds
HUD Displays: Free-form mirror machining
l Medical Devices
Endoscope Lenses: Micro-optical lens molds
Ophthalmic Devices: Intraocular Lens (IOL) and Contact Lens molds
Surgical Instruments: Precision optical inspection components
l Industrial & Optical Fields
Infrared Optics: Infrared lenses and reflectors for defense, security, and thermal imaging applications
Lighting Systems: LED lighting covers, traffic signal light covers
Micro-structured Optics: Light guide plate molds, Fresnel lens molds
Film Rollers: Roller molds for producing large-scale micro-structured optical films, the most economical method for mass-producing optical film
Litian Century employs cutting-edge facilities to produce and inspect our diamond tools. With over 20 years of experience, our technicians possess deep expertise in diamond craftsmanship. Continuous innovation keeps us ahead of the competition.
We offer both First-class Natural Diamond and Advanced Synthetic Diamond, both essential for the superior performance and durability of our Single Crystal Diamond Turning Tools. Select the ideal material for your specific needs. Leverage our innovations to ensure you're using highly efficient, reliable tools that minimize errors and lower production costs.
Tool Clamping
l Handle the tool lightly when clamping
l Do not contond tip directly
l After removing the Diamond Turning Tool, place it back in the tool box immediately
l Do not leave tools exposed to avoid damaging the diamond
Tool Cleaning
l Wipe the diamond tips gently with a clean foam stick dipped in industrial alcohol
l Avoid excessive force or abrasive materials that could damage the cutting edge
① After-sales Services
We have professional after-sales service team and after-sales system which called "Litian Century After-sales System". This system is used to manage the information of after-sales maintenance products, and can realize the functions of inquiring the grinding progress, grinding cost and feedback of after-sales problems. Advantages of the system: "zero consultation, more time saving, more convenient, more efficient", users can log in at any time to check.
② Quality Assurance
The company is equipped with advanced inspection equipment and trained inspection personnel which assure us carry out inspections during each process. At the same time, every single tool can be sent to our customers after the professional inspection by Quality Control Center.
