PCD Diamond Milling Cutter from the DTN Z2+2 Series – for Finishing, Nesting and Formatting Operations

Index: DTN.12.035.20.0SL

The industrial diamond milling cutter from the DTN group has been designed for specialised formatting, nesting, and precise finishing operations on overhead spindle milling machines and CNC centres. The tool utilises a blade arrangement of Z2+2 -  polycrystalline diamond (PCD) inserts distributed on four cutting spirals, supported by a tungsten carbide (HM) front insert. The cutter body is made from high-hardness steel (> 28 HRC). This construction facilitates free dust removal, while the ground shank part in a tight tolerance class H6 minimises radial runout, protecting the spindle bearings and ensuring excellent edge condition after machining. 

Design Advantages and Technical Properties:

• Z2+2 Geometry based on four spirals: An arrangement that provides high cutting efficiency and excellent surface finish of the material while maintaining great operational stability.
• Laser processing of cutting edges (ablation): The DIA blade profiles are finished directly with a laser beam, achieving edge radii around 15 µm and ensuring a cutting surface free from micro-chipping.
• Polished chip flutes and cutting area: The smoothed back of the PCD insert combined with capacious chip channels prevents material from sticking and facilitates quick dust removal from the cutting zone.
• Low roughness of the shank: The shank surface with a roughness indicator of Ra ≤ 0.3 µm secures the cutter from rotating in the holder and eliminates the risk of wearing the cone in the spindle.
• Dynamic balancing in class G2.5: Certified static-dynamic balancing in an elevated class G2.5 (according to ISO/EN) reduces noise and vibrations generated at high speeds.
• Regrinding possibility: depending on the height of the diamond insert used: an insert H = 2.0 mm allows for 2 regrindings, an insert H = 2.5 mm enables regrinding a maximum of 2–3 times, variants H = 3.0 mm / H = 3.5 mm allow for regrinding a maximum of 3–4 times, while inserts H = 4.0 mm / H = 4.5 mm permit regrinding a maximum of 4–6 times.

Intended Use and Application Scope:

The tool is intended for cutting, nesting, contour milling, and grooving operations.

It performs excellently in processing materials such as: raw and laminated MDF board, raw and laminated chipboard, as well as raw and laminated plywood.
