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

Index: DTN.16.025.20.0SL

The industrial diamond cutter from the DTN group has been created for specialised formatting, nesting, and precise finishing operations of materials on overhead spindle milling machines and CNC centres. The tool features a blade arrangement Z2+2 -  with polycrystalline diamond (PCD) inserts placed on four working spirals, supported by a solid carbide (HM) front plate. The cutter's shank is made from high-hardness steel (≥ 28 HRC). This construction facilitates the free removal of dust, while the ground shank part with tight tolerance class H6 eliminates radial runout, protecting the spindle bearings and ensuring an excellent edge condition after machining. 

Design advantages and technical properties:

• Z2+2 geometry based on four spirals: A configuration providing high cutting efficiency and an excellent standard of surface finishing while maintaining high stability during operation.
• Laser processing of cutting edges (ablation): The DIA blade profiles are finished directly with a laser beam, allowing for edge radii at the level of 15 µm and ensuring a cutting plane free from micro-chipping.
• Polished chip grooves and entry zone: The smoothed back part of the PCD diamond insert combined with ample chip channels prevents the sticking of the cut material and enhances the rapid removal of dust 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 of the cone in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the stringent class G2.5 (according to ISO/EN) reduces noise and vibrations generated at the highest speeds.
• Regeneration possibility: Depending on the height of the applied diamond insert: insert H = 2.0 mm allows for 2-fold sharpening, insert H = 2.5 mm permits sharpening up to 2–3 times, variants H = 3.0 mm / H = 3.5 mm allow sharpening up to 3–4 times, while inserts H = 4.0 mm / H = 4.5 mm enable sharpening up to 4–6 times.

Usage and application range:

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

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