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

Index: DTN.18.025.20.0SL

The industrial diamond cutter from the DTN group has been designed for specialised formatting, nesting, and precise finishing operations of materials on overhead spindle milling machines and CNC centres. The tool utilises a blade arrangement Z2+2 -  where polycrystalline diamond (PCD) inserts are arranged on four cutting spirals, supported by a solid carbide (HM) front insert. The cutter's shank consists of a body made from high-hardness steel (> 28 HRC). This design enhances the free removal of dust, while the ground clamping section in a tight tolerance class H6 eliminates radial runout, safeguarding the spindle bearings and ensuring an excellent edge condition after processing. 

Design advantages and technical properties:

• Z2+2 geometry based on four spirals: A configuration providing high cutting efficiency and an excellent surface finish standard while maintaining high operational stability.
• Laser treatment of cutting edges (ablation): The profiles of the DIA blades are finished directly with a laser beam, allowing for edge radii at the level of 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 workpiece from sticking and facilitates rapid dust removal from the cutting zone.
• Low roughness of the clamping section: The surface of the shank with a roughness index of Ra ≤ 0,3 µm secures the cutter against rotation 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 G2.5 class (according to ISO/EN) reduces noise and minimises vibrations generated at high speeds.
• Regrindability: Depending on the height of the used diamond insert: an insert H = 2.0 mm allows for 2-regrinds, an insert H = 2.5 mm permits a maximum of 2–3 regrinds, while H = 3.0 mm / H = 3.5 mm allows for a maximum of 3–4 regrinds, and 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 intended for cutting, nesting, peripheral milling, and grooving operations.

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