PCD Diamond Mill from the DTN Z2+2 Series – for finishing, nesting, and formatting processing

Index: DTN.20.035.20.0SR

The industrial diamond mill from the DTN group is designed for specialised formatting, nesting, and precise finishing operations on overhead spindle milling machines and CNC centres. The tool uses the Z2+2 - blade arrangement, with polycrystalline diamond (PCD) inserts placed on four working spirals, supported by a front insert made of sintered carbide (HM). The shank of the mill consists of a body made of high-hardness steel (> 28 HRC). This construction facilitates the free removal of dust, while the ground shank in strict tolerance class H6 eliminates 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: A configuration that provides high cutting efficiency and an excellent standard of surface finish while maintaining high 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 surface free from micro-chips.
• Polished chip grooves and entry zone: The smoothed rear area of the PCD diamond insert combined with spacious chip channels prevents material adhesion and enhances quick dust removal from the cutting zone.
• Low roughness of shank: The shank surface with a roughness indication of Ra ≤ 0.3 µm prevents the mill from rotating in the holder and eliminates the risk of cone wear in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in an elevated class G2.5 (according to ISO/EN) reduces noise and decreases vibrations generated at high speeds.
• Regeneration capability: Depending on the height of the applied diamond blade: insert H = 2.0 mm allows for 2 re-sharpenings, insert H = 2.5 mm enables sharpening a maximum of 2–3 times, variants H = 3.0 mm / H = 3.5 mm allow for a maximum of 3–4 times, while inserts H = 4.0 mm / H = 4.5 mm enable sharpening a maximum of 4–6 times.

Application and scope of use:

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

It works excellently in the processing of materials such as: raw and laminated MDF board, raw and laminated chipboard, and raw and laminated plywood.
