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

Index: DTN.12.025.20.0SL

The industrial diamond cutter from the DTN group is designed for specialised formatting, nesting, and precise finishing operations on spindle milling machines and CNC centres. The tool features a cutting edge configuration of Z2+2 -  polycystalline diamond (PCD) tips arranged on four working spirals, supported by a carbide (HM) frontal tip. The cutter's shaft is made of high-hardness steel (> 28 HRC). This design facilitates efficient dust removal, while the ground clamping section in a tight tolerance class of H6 minimises radial runout, protecting the spindle bearings and ensuring an excellent edge condition after machining. 

Construction advantages and technical properties:

• Z2+2 geometry based on four spirals: A layout that provides high cutting efficiency and an excellent finish standard for the material surface while maintaining great operational stability.
• Laser finishing of cutting edges (ablation): DIA blade profiles are finished directly with a laser beam, achieving edge radii in the range of 15 µm and ensuring a cutting plane free from micro-chipping.
• Polished chip grooves and cutting area: The smoothed rear section of the PCD diamond tip combined with ample chip channels prevents material sticking and improves rapid dust removal from the cutting zone.
• Low roughness of the clamping part: The shaft surface with a roughness index of Ra ≤ 0.3 µm protects the cutter from rotating in the holder and eliminates the risk of wear on the cone in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in an exceptional class of G2.5 (according to ISO/EN) reduces noise and vibrations generated at high speeds.
• Regeneration possibility: Depending on the height of the applied diamond tip: tip H = 2.0 mm allows for 2 sharpening, tip H = 2.5 mm allows for sharpening a maximum of 2–3 times, variants H = 3.0 mm / H = 3.5 mm allow for sharpening a maximum of 3–4 times, while tips H = 4.0 mm / H = 4.5 mmenable sharpening a maximum of 4–6 times.

Intended use and application range:

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

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