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

Index: DTN.20.045.20.0SR

This industrial diamond cutter from the DTN group is designed for specialised formatting operations, nesting, and precise finishing of materials on overhead spindle mills and CNC centres. The tool employs a blade configuration 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 shaft is made of high-hardness steel (> 28 HRC). This design enables efficient dust removal, while the ground shank with tight tolerance class H6 minimises 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 providing high cutting efficiency and excellent surface finish while maintaining great work stability.
• Laser treatment of cutting edges (ablation): DIA blade profiles are finished directly with a laser beam, achieving edge radii of approximately 15 µm and ensuring a cutting plane free from micro-chips.
• Polished chip grooves and cutting zone: The smooth back of the PCD diamond insert combined with capacious chip channels prevents material from sticking and facilitates rapid dust removal from the cutting zone.
• Low roughness of the shank: The shaft surface with a roughness index of Ra ≤ 0.3 µm ensures the cutter does not rotate in the holder and eliminates the risk of wear on the spindle cone.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the high standard of G2.5 (according to ISO/EN) minimises noise and reduces vibrations generated at high speeds.
• Regrinding capability: depending on the height of the diamond insert used: insert H = 2.0 mm allows for 2 regrinds, insert H = 2.5 mm enables 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 application range:

The tool is designed for cutting, nesting, peripheral milling, and mortising operations.

It performs excellently in machining materials such as: raw and laminated MDF boards, raw and laminated chipboards, and raw and laminated plywood.
