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

Index: DTN.25.025.25.0SR

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 system 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 body is made of high-hardness steel (> 28 HRC). This construction facilitates the free removal of dust, while the ground shank in a tight tolerance class H6 eliminates radial run-out, which protects the spindle bearings and guarantees an excellent edge condition after machining. 

Design advantages and technical properties:

• Z2+2 geometry based on four spirals: A configuration that provides high cutting efficiency and an excellent surface finish of the material while maintaining high operational stability.
• Laser processing of cutting edges (ablation): The DIA blade profiles are finished directly by a laser beam, allowing for edge radii at the level of 15 µm and guaranteeing a cutting surface free from micro-chips.
• Polished chip grooves and cutting zone: The smoothed back of the PCD diamond insert combined with capacious chip channels prevents material from sticking and facilitates quick removal of dust from the cutting zone.
• Low roughness of the shank: The shank surface with a roughness indicator of Ra ≤ 0.3 µm secures the cutter against rotating 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 stringent G2.5 class (according to ISO/EN) reduces noise and vibration generated at the highest speeds.
• Regeneration possibility: depending on the height of the used diamond insert: insert H = 2.0 mm allows for 2 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 allow for sharpening a maximum of 4–6 times.

Intended use and application range:

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

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