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

Index: DTN.16.045.16.0SL

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

Construction Advantages and Technical Properties:

• Z2+2 Geometry based on four spirals: A configuration providing high cutting performance and excellent surface finishing standards while maintaining great operational stability.
• Laser treatment of cutting edges (ablation): The blade profiles are finished directly with a laser beam, achieving edge radii of around 15 µm and ensuring a cutting surface free from micro-chipping.
• Polished chip grooves and cutting zone: The smoothed rear part of the PCD diamond insert combined with spacious 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 index of Ra ≤ 0.3 µm protects the cutter from rotating in the holder and eliminates the risk of wear on the taper in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in a stringent class of G2.5 (according to ISO/EN) reduces noise and minimises the vibrations generated at high speeds.
• Regrindability: Depending on the height of the diamond insert used: an insert H = 2.0 mm allows for 2x sharpening, an insert 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 inserts H = 4.0 mm / H = 4.5 mm allow for sharpening up to 4–6 times.

Intended Use and Application Range:

The tool is intended 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, and raw and laminated plywood.
