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

Index: DTN.20.035.20.0SL

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

Construction advantages and technical properties:

• Z2+2 Geometry based on four spirals: A configuration that provides high cutting efficiency and an excellent surface finish standard while maintaining great stability during operation.
• Laser edge processing (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 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 workpiece adhesion and facilitates quick dust removal from the cutting area.
• Low roughness of the shank: The surface of the shank with a roughness index of Ra ≤ 0.3 µm secures the cutter against rotating in the holder and eliminates the risk of wear on the spindle taper.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the strict class G2.5 (according to ISO/EN) reduces noise and diminishes vibrations generated at high speeds.
• Regeneration capability: Depending on the height of the diamond insert used: insert H = 2.0 mm allows for 2 sharpening, insert H = 2.5 mm enables sharpening up to 2-3 times, variants H = 3.0 mm / H = 3.5 mm allow for sharpening up to 3-4 times, while inserts H = 4.0 mm / H = 4.5 mm enable sharpening up to 4-6 times.

Intended use and application range:

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

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