Three-blade diamond milling cutter PCD DTM DENSIMET® – for nesting, formatting, and finishing processing

Index: DTM.12.021.12.1DRN

The industrial diamond milling cutter of the DTM DENSIMET® series is designed for high-performance nesting, cutting, and finishing processing on CNC centres and overhead spindle milling machines. The advanced tool design consists of three full polycrystalline diamond blades arranged on six spirals, complemented by a diamond front plate that enables efficient and stable axial penetration into the material. The body made of DENSIMET® (heavy alloy with advanced vibration-damping capabilities) ensures high structural stiffness and vibration reduction during processing. The ground shank in tolerance class H6 eliminates radial runout, protecting the spindle bearing assembly and guaranteeing an excellent edge finishing standard.

Design advantages and technical properties:

• Innovative DENSIMET® based body: The use of heavy metals with high density precisely dampens vibrations during cutting, which translates into longer tool life and ideal quality of the processed surface.
• Z3+3 blade arrangement on six spirals (positive/negative): Three full polycrystalline diamond blades arranged on six spirals in either positive or negative configuration guarantee an excellent edge finishing standard for the panel and the proper direction of chip ejection (upwards or downwards).
• PCD diamond front plate: The tool's front equipped with a PCD plate facilitates smooth, fluid, and stable insertion of the cutter in the Z-axis during nesting operations.
• Laser treatment of cutting edges (ablation): The edges of the DIA blades are finished directly with a laser beam, achieving edge radii around 15 µm and ensuring a cutting surface free from micro-chipping.
• Polished chip grooves and cutting zone: The smooth back of the PCD diamond plate combined with capacious chip channels prevents chip adhesion and facilitates quick dust removal from the cutting zone.
• Low roughness of the gripping part: The surface of the shank with a roughness indicator of Ra ≤ 0.3 µm secures the cutter against rotation in the holder and eliminates the risk of wear on the cone in the spindle.
• Dynamic balancing within the G2.5 standard: Certified static-dynamic balancing in the 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 blade: plate H = 2.0 mm allows for 2 times sharpening, plate 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 plates H = 4.0 mm / H = 4.5 mm enable sharpening a maximum of 4–6 times.

Purpose and scope of use:

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

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