PCD diamond milling cutter from the DTA series for finishing machining of boards and plywood

Index: DTA.20.055.20.0SR

The industrial diamond milling cutter from the DTA series is designed for formatting and finishing machining on CNC centres and overhead milling machines. The tool's construction features a diamond blade arranged on three spirals and a front plate made of cemented carbide (HM). The blades are mounted on a body made of steel with increased hardness (> 28 HRC) or – in selected variants – from a cemented carbide monolith (HM). The thoughtful geometry of the cutting edges ensures stable guidance in the machined material, while the high clamping accuracy class H6 limits radial runout, protecting the spindle and guaranteeing excellent edge finish quality. The tool is available in both right and left rotations.

Design advantages and technical properties:

• Laser treatment of cutting edges (ablation): The profiles of the DIA blades are finished directly with a laser beam, allowing for edge radii of around 15 µm and guaranteeing a cutting face free from micro-chipping.
• Polished chip grooves and cutting zone: The smoothed rear part of the PCD diamond blade combined with capacious chip channels prevents material sticking and facilitates quick dust removal from the cutting zone.
• Low roughness of the shank: The surface of the shank with a roughness indicator of Ra ≤ 0.3 µm protects the cutter from rotating in the holder and eliminates the risk of wear on the spindle cone.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the stringent class G2.5 (according to ISO/EN) reduces noise and minimizes vibrations generated at high speeds.
• Sharpening specification (height of the PCD plate): 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.

Intended use and application scope:

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

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