Diamond milling cutter PCD from the DTN Z2+2 series – for finishing, nesting and formatting processing

Index: DTN.09.025.09.5DR

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 uses a blade arrangement Z2+2 -  with polycrystalline diamond (PCD) inserts arranged on four cutting spirals, supported by a cutting blade made of sintered carbide (HM). The shaft of the cutter consists of a body made from high-hardness steel (> 28 HRC). This design facilitates the free removal of dust, while the ground shank in a tight tolerance class H6 eliminates radial runout, which protects the spindle bearings and guarantees an excellent edge condition after processing. 

Structural advantages and technical properties:

• Z2+2 geometry based on four spirals: An arrangement that provides high cutting efficiency and excellent surface finish standards while maintaining great stability during operation.
• Laser processing of cutting edges (ablation): The DIA blade profiles are finished directly with a laser beam, allowing edge radii down to 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 capacious chip channels prevents the sticking of the cut material and facilitates the rapid removal of dust from the cutting zone.
• Low roughness of the shank: The surface of the shaft with a roughness index of Ra ≤ 0.3 µm secures the cutter from spinning in the holder and eliminates the risk of wear on the spindle cone.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in a high-grade G2.5 class (according to ISO/EN) reduces noise and vibrations generated at high speeds.
• Regrinding capability: depending on the height of the applied diamond insert: insert H = 2.0 mm allows for 2 regrinds, insert H = 2.5 mm allows for a maximum of 2–3 regrinds, variants H = 3.0 mm / H = 3.5 mm allow for a maximum of 3–4 regrinds, while inserts H = 4.0 mm / H = 4.5 mm allow for a maximum of 4–6 regrinds.

Intended use and scope of application:

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

It performs excellently in processing materials such as: raw and laminated MDF board, raw and laminated particle board, as well as raw and laminated plywood.
