Single Crystal Diamond Turning Tools

Single crystal diamond turning tool is a kind of ultra-precision machining tool, which is mainly used in the processing of non-ferrous metals and non-metallic hard brittle materials such as nickel, copper, optical glass and silicon wafers.

Our original precision machining technology enables the production of diamond tools and dies with exceptionally sharp and durable cutting edges. The advanced surface finish ensures that no chips fuse or deposit on the rake face, allowing the tool to consistently produce high-quality, smooth surfaces, even during continuous or high-speed operations.

Custom Tools from Litian Century

If one of our standard off-the-shelf tool designs doesn’t meet your specific requirements, Litian Century’s engineering team is ready to create a custom tool tailored to your application — free of charge.

We offer a complimentary design service to ensure you get the right tool that fits your machine, material, and production goals before purchase.

Our custom tool solutions can be designed as:

· Solid shank tools with offsets for edging or back-chamfer operations
· Round shank tools for enhanced balance and precision
· Tools for boring, special milling, trepanning, facing, or counter-boring applications

And most importantly, we provide a wide selection of diamond types, each suited to different performance requirements:

· Polycrystalline CVD (Chemical Vapor Deposition) tipped tools
· Monocrystalline HPHT (High Pressure, High Temperature) synthetic (Dodec 110 Orientation)
· Monocrystalline CVD synthetic (Dodec 110 Orientation)
· Mono-Die synthetic (Dodec 110 Orientation)
· Monocrystalline Natural (Dodec 110 Orientation)
· Monocrystalline Sumitomo synthetic (Cubic 100 Orientation)

Every diamond type has its own unique advantages in precision, durability, and surface finish.

Tool material options include:

· Steel – ideal for insert tooling requiring tapped holes
· Tungsten Carbide – exceptional stiffness for long-reach applications
· Molybdenum – excellent vibration damping characteristics
· Titanium – lightweight for high-speed and Fast Tool Servo systems

Wide Variety of Toolholders with Insert

An insert–toolholder combination maximizes flexibility and extends the tool’s reach to the component, while maintaining a versatile and easily replaceable cutting tip. Equipping your toolholder with several ISO-standard cemented carbide carriers enables quick tool changes, minimal downtime, and maximum productivity during every shift.

We offer a wide range of toolholders, including offset and angled designs, available in the following materials:

· Steel – Ideal for insert tooling requiring a tapped hole.
· Tungsten Carbide – Provides excellent stiffness for long-reach applications.
· Molybdenum – Delivers superior vibration damping.
· Titanium – Lightweight and perfectly suited for Fast Tool Servo systems.

At Litian Century, we combine innovation, precision, and decades of expertise to deliver custom tooling solutions that maximize your productivity and performance.

Optimized Crystal Orientation for Superior Stability and Longevity

Through precise control of diamond crystal orientation using X-ray technology, the diamond abrasive grains are firmly bonded to uniquely shaped carbide material. This innovative structure—combining a specially designed tip and holder—ensures accurate tool positioning similar to throwaway tips. The optimized design prevents chip fusion or buildup on the rake face, maintaining excellent surface quality even during extended cutting operations.

Key Characteristics

· Achieves an average tool life 1.5 to 2 times longer than conventional tools.
· Our proprietary brazing method provides a firm diamond bond, eliminating vibration during cutting.
· The lid-free design allows for smooth chip flow over the rake face, enhancing machining accuracy and overall performance.

Litian Century Diamond Tools creates all the lathe single crystal diamond cutting tool you need, whether it is an elliptical shape, cylindrical and conical rear angles, multiple radius on a tool. Whatever you need, please check with us and we can make it.

Usage Attentions

Applications:

Single Crystal Diamond Turning Tools are widely used in the processing of various infrared lenses, concave-convex lenses, dry diffraction lenses, and fresnel lenses, optical camera lenses, mobile phone camera lenses, photo receptor drums, digital devices etc.

Litian Century Diamond Tools creates turning, milling, boring and grooving tools suitable for all kinds of non-ferrous materials as well as certain crystals. Materials that can be machined with single crystal diamond tools as follows: Copper, Nickel, Aluminum, Gold, Brass, Carbide, Plastics, Zinc selenide, Zinc sulfide, Calcium fluoride, KDP, Germanium, Silicon etc.

The angle between the tip of the diamond mold turning tool we process is at least 15°. Even in the case of a large arc, the waviness can be controlled below 30nm which ensure that the molds of various concave and convex lenses and Fresnel lenses processed in the field of optical lens processing can have a very ideal radius of curvature and very high reproducibility and stability.

Ideal for precision machining of non-ferrous metal components such as automotive parts (pistons, aluminum wheels, compressors, commutators), plastic lenses, resin-molded components, HDD parts, and aluminum die-cast products.
