The Pinnacle of Cutting Tool Technology: Single Crystal Diamond

Single Crystal Diamond (SCD), also known as Monocrystalline Diamond (MCD), is a synthetically grown diamond material with an almost flawless crystal structure, offering unmatched performance for ultra-precision machining applications.

• Atomically Sharp Cutting Edge
  SCD inserts can be precision-ground to an extremely sharp, defect-free cutting edge with a nanometer-scale edge radius, enabling highly stable cutting with minimal cutting force, material deformation, and burr formation.

• Exceptional Surface Finish Quality
  Capable of producing mirror-like surface finishes (Ra < 0.01 μm) directly during machining, SCD tools often reduce or eliminate the need for secondary polishing or lapping processes.

• Outstanding Hardness & Wear Resistance
  With exceptional abrasion resistance on suitable materials, Single Crystal Diamond tools provide excellent edge retention and long service life in ultra-precision machining environments.

• Excellent for Non-Ferrous & Polymer Materials
  SCD performs exceptionally well when machining non-ferrous metals such as aluminum alloys, copper alloys, oxygen-free copper, brass, bronze, gold, and silver, as well as polymers including PMMA/acrylic and polycarbonate, along with certain soft composite materials.

• Application Considerations
  Although extremely hard, Single Crystal Diamond is more brittle than PCD or carbide materials. Optimal performance requires ultra-precision machine tools with high dynamic stability, minimal vibration, and carefully controlled machining parameters. SCD is generally not recommended for ferrous metals due to chemical affinity or for very hard ceramics because of brittleness concerns.

Customized Insert Geometry to Your Exact Requirements

We specialize in manufacturing Single Crystal Diamond (SCD/MCD) inserts with precisely controlled geometries tailored to your specific machining application and tool holder design. Based on your detailed drawings and technical requirements, we can produce inserts featuring:

• Micro-Precision Dimensions & Tight Tolerances
  Our ultra-precision manufacturing capability enables exceptional accuracy on critical geometric features. For example, we can achieve highly controlled dimensions such as insert width, cutting edge arc radius, center height, and body thickness with micron-level precision, depending on the insert design and application requirements.

• Complex Cutting Edge Geometries
  We can manufacture highly customized cutting edge profiles, including specific rake angles, clearance angles, edge radii, facet designs, and special edge configurations optimized for turning, milling, boring, fly-cutting, grooving, and scribing applications.

• Controlled Crystal Orientation
  The crystallographic orientation of the diamond can be carefully controlled relative to the cutting edge direction to maximize wear resistance, edge stability, and machining performance for specific materials and cutting conditions.
