In the era of rapid development of intelligent manufacturing, people's requirements for smart homes, smart cars and smart digital devices are increasing, and the requirements for the intelligence and precision of production equipment getting higher and higher.

Nowadays, the lenses of car camera systems and mobile phone camera systems are required to reach the nanometer level, and such modules must be achieved by ultra-precision machining.

Of course, in order to achieve such a high precision module processing, the choice of ultra-precision diamond tools is particularly important. Because the accuracy of the tool determines the accuracy of the machining module.

The ultra-precision diamond tools of Litian Century, which select high-quality diamond raw materials, strictly control the processing technology of the tool, and the tool waviness can be controlled within 50nm or even 10nm.

Only by choosing an ultra-precision diamond tool with minimal accuracy to match the mature cutting process, can a camera module with minimal accuracy be presented.

Applications Across Ultra-Precision Manufacturing and Optics

Anticipating market needs and collaborating closely with customers in both industry and academia, Litian Century develops application-oriented solutions spanning the full spectrum of ultra-precision manufacturing and optics. To achieve optimal cutting efficiency, the appropriate tool geometry should be selected for each material. Our tools are available with either natural or synthetic single-crystal diamonds, offering a range of radius sizes and rake angles. Each diamond is carefully oriented to maximize the wear resistance and longevity of the cutting edge.

Diamond Tools for Flycutting

We have developed application-oriented solutions that cover the full spectrum of ultra-precision manufacturing and optics.

The Process of Flycutting

Flycutting uses a single cutting edge to create a flat surface through tool rotation, while the workpiece remains fixed or moves at table feed speed. This method is flexible, economical, and accurate, producing high-quality surfaces. A wide range of tool holders, shanks, and tool edge geometries can be applied depending on component shape, machine type, cutting parameters, and machining strategies.

Diamond Tools for Milling

We provide solutions tailored to ultra-precision manufacturing and optics.

The Process of Milling

Milling is the most versatile machining process, limited mainly by the creativity of the CNC program. With a rotating tool and a fixed or slow-moving prismatic workpiece, almost any shape can be produced. Milling with monocrystalline diamond offers outstanding wear resistance in non-ferrous materials, ensuring long tool life, reduced tool change time, and improved overall economy. Applications range from milling haptics for intraocular lenses to milling lens arrays, ideally on air-bearing spindle machines.

Diamond Tools for Turning

We have created advanced solutions across ultra-precision manufacturing and optics.

The Process of Turning

Turning is the most widely used ultra-precision machining process, supported by the large installed base of 2- and 3-axis air-bearing turning machines. Applications vary: spectacle lenses are finish-turned between rough milling and grinding; infrared optics and mirrors may be fully finished in turning; and molds for contact lenses, intraocular lenses, and most electro-optics lenses are typically produced through precision turning.

Electro-Mechanical Engraving

Gravure printing is used for long, high-quality print runs, including magazines, catalogues, packaging, fabric, wallpaper, postage stamps, and decorative laminates.

The Process

In gravure printing, images are created by depressions in the surface of a printing plate. The cells are filled with ink, and excess ink is removed with a doctor blade. A rubber-covered roller then presses the paper onto the plate to transfer the ink. Printing cylinders, usually copper-plated steel with a chrome finish, are most commonly produced by diamond engraving, also known as electro-mechanical engraving.

Diamond Anvils

We manufacture precision diamond anvils for universities and national laboratories worldwide, offering both standard and custom designs at affordable prices.

·  Available in Type 1A and Type 2A single-crystal CVD diamonds.

·  Options for Low Fluorescence (LF) and Ultra-Low Fluorescence (ULF).

·  Raman-selected stones verified by independent national laboratories.

Nearly all of our diamonds feature low or ultra-low birefringence, measured with a Berek Compensator:

·  <0.0001 = Low birefringence

·  <0.00005 = Ultra-low birefringence

Birefringence is verified after each cutting and polishing step to ensure compliance with specifications. We also offer single or double bevels, with tolerances held to within a few microns. Standard parallelism between culet and table is <0.1°.
