PCD Diamond Milling Cutter from the DTN Z2+2 Series – for Finishing, Nesting and Formatting

Index: DTN.16.025.20.0SR

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

Design Advantages and Technical Properties:

• Z2+2 Geometry  based on four spirals: A configuration that provides high cutting performance and excellent surface finishing quality while maintaining high operational stability.
• Laser-treated cutting edges (ablation): The DIA blade profiles are finished directly with a laser beam, achieving edge radii of approximately 15 µm and guaranteeing a cutting surface free from micro-chipping.
• Polished chip grooves and clearance area: The smoothed rear part of the PCD insert combined with capacious chip channels prevents material from sticking and facilitates quick dust removal from the cutting zone.
• Low roughness of the shank: The surface of the shank has a roughness index of Ra ≤ 0.3 µm, which prevents the cutter from rotating in the holder and eliminates the risk of wear on the spindle taper.
• Dynamic balancing to G2.5 standard: Certified static and dynamic balancing in the high standard of G2.5 (according to ISO/EN) reduces noise and minimizes vibrations at high speeds.
• Regeneration possibility: Depending on the height of the diamond insert used: insert H = 2.0 mm allows for 2 sharpening sessions, insert H = 2.5 mm permits 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.

Applications and Scope of Use:

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

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