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

Index: DTN.25.025.25.0SL

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 uses a blade arrangement Z2+2 -  consisting of polycrystalline diamond (PCD) inserts arranged on four cutting spirals, supported by a front plate made of hard metal (HM). The cutter's body is made of high-hardness steel (> 28 HRC). This design facilitates efficient dust extraction, while the ground shank with a tight tolerance class H6 eliminates radial runout, protecting the spindle bearings and ensuring excellent edge condition after processing. 

Design advantages and technical properties:

• Z2+2 geometry based on four spirals: An arrangement that provides high cutting efficiency and an excellent standard of surface finish while maintaining great work stability.
• Laser processing of cutting edges (ablation): The tool 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 rear part of the PCD diamond insert combined with spacious chip channels prevents material from sticking and aids in the rapid removal of dust from the cutting area.
• Low roughness of the shank: The shank surface with a roughness factor of Ra ≤ 0.3 µm prevents the cutter from rotating in the holder and eliminates the risk of wear on the taper in the spindle.
• Dynamic balancing to standard G2.5: Certified static-dynamic balancing in a stringent class G2.5 (according to ISO/EN) reduces noise and vibrations generated at high speeds.
• Regeneration capability: depending on the height of the applied diamond insert: an insert H = 2.0 mm allows for 2 times sharpening, an 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 enable sharpening a maximum of 4–6 times.

Intended use and application range:

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

It works perfectly for processing materials such as: raw and laminated MDF board, raw and laminated chipboard, as well as raw and laminated plywood.
