PCD Diamond Milling Cutter from the DTN Z2+2 Series – for finishing, nesting, and formatting operations

Index: DTN.12.025.12.5SR

The industrial diamond milling cutter from the DTN group has been designed for specialised formatting, nesting, and precision finishing operations on overhead spindle milling machines and CNC centres. The tool features a cutting edge arrangement of Z2+2 -  polycrystalline diamond (PCD) plates arranged on four working spirals, supported by a front plate made of hard metal (HM). The cutter shaft consists of a body made of high-hardness steel (> 28 HRC). This design facilitates the free removal of dust, while the ground shank with a close tolerance class of H6 eliminates radial runout, safeguarding 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 an excellent standard of surface finish while maintaining great work stability.
• Laser processing of cutting edges (ablation): The DIA blade profiles are finished directly with a laser beam, achieving edge radii of around 15 µm and ensuring a cutting plane free of micro-chipping.
• Polished chip grooves and cutting zone: The smooth back part of the PCD diamond plate combined with spacious chip channels prevents material build-up and enhances quick dust removal from the cutting area.
• Low roughness of the shank: The shank surface with a roughness index of Ra ≤ 0.3 µm prevents the cutter from rotating in the holder and eliminates the risk of cone wear in the spindle.
• Dynamic balancing in the G2.5 standard: Certified static-dynamic balancing in an elevated class of G2.5 (according to ISO/EN) reduces noise and diminishes vibrations generated at the highest speeds.
• Regeneration capability: Depending on the height of the applied diamond blade: a plate H = 2.0 mm allows for 2-fold sharpening, a plate H = 2.5 mm enables sharpening up to 2–3 times, variants H = 3.0 mm / H = 3.5 mm allow for sharpening up to 3–4 times, while plates H = 4.0 mm / H = 4.5 mm enable sharpening up to 4–6 times.

Intended use and application range:

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

It performs excellently in machining materials such as: raw and laminated MDF boards, raw and laminated chipboards, as well as raw and laminated plywood.
