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

Index: DTN.16.045.20.0SL

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 features a Z2+2 -  blade arrangement with polycrystalline diamond (PCD) inserts distributed across four cutting spirals, supported by a front insert made of sintered carbide (HM). The cutter shank consists of a body made of high-hardness steel (> 28 HRC). This construction facilitates the free evacuation of dust, while the ground gripping section with a tight tolerance class of H6 eliminates radial runout, ensuring the spindle bearings are protected and guaranteeing excellent edge condition after processing. 

Design Advantages and Technical Properties:

• Z2+2 Geometry based on four spirals: A configuration that offers high cutting efficiency and excellent surface finishing standards 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 at the level of 15 µm and ensuring a cutting surface free from microchipping.
• Polished chip grooves and cutting zone: The smoothed rear part of the PCD diamond insert combined with capacious chip channels prevents material from sticking and enhances the rapid removal of dust from the cutting zone.
• Low roughness of the gripping section: 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 class G2.5: Certified static-dynamic balancing in the stringent class G2.5 (according to ISO/EN) reduces noise and vibration generated at high speeds.
• Regeneration capability: Depending on the height of the applied diamond insert: insert H = 2.0 mm allows for 2 times sharpening, insert H = 2.5 mm enables 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 inserts H = 4.0 mm / H = 4.5 mm enable sharpening a maximum of 4–6 times.

Intended Use and Range of Application:

The tool is designed 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, and raw and laminated plywood.
