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

Index: DTM.12.024.12.1DRN

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

Design advantages and technical properties:

• Innovative body based on DENSIMET®: The use of heavy metals with high density precisely dampens vibrations during cutting, resulting in longer tool life and ideal quality of the machined surface.
• Z3+3 blade arrangement on six spirals (positive/negative): Three full polycrystalline diamond blades arranged on six spirals in either a positive or negative configuration ensure an excellent standard of edge finish for the board and the appropriate direction for chip ejection (upward or downward).
• PCD cutting tip: The tool’s face equipped with a PCD tip facilitates free, smooth and stable plunge cutting in the Z-axis during nesting operations.
• Laser cutting edge processing (ablation): The DIA blade profiles are finished directly with a laser beam, achieving cutting edge radii of approximately 15 µm and guaranteeing a cutting plane free of micro-chipping.
• Polished chip grooves and cutting edge zone: The smoothed rear part of the PCD diamond tip combined with spacious chip-flushing channels prevents chip sticking and facilitates quick removal of dust from the cutting zone.
• Low roughness of the shank: The shank surface with a roughness index of Ra ≤ 0.3 µm secures the cutter against rotation in the holder and eliminates the risk of wear on the spindle taper.
• Dynamic balancing to standard G2.5: Certified static-dynamic balancing in the stringent class G2.5 (according to ISO/EN) reduces noise and minimises vibrations generated at high speeds.
• Reconditioning capability: Depending on the height of the diamond blade used: a tip H = 2.0 mm allows for 2 sharpening cycles, a tip 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 tips H = 4.0 mm / H = 4.5 mm allow for sharpening up to 4–6 times.

Purpose and scope of application:

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

It is particularly effective in machining materials such as: raw and laminated MDF board, raw and laminated chipboard, as well as raw and laminated plywood.
