Embodiment Construction

[0014] see figure 1 , a PCD diamond composite reamer 1, including a cutter body 1 and a blade 5, the front part of the blade 5 is a tungsten steel rough reamer edge 2, the middle part of the blade is a PCD diamond fine reamer edge 3, and the PCD diamond fine reamer The rear portion of the reamer blade is provided with a PCD diamond shockproof blade 4 .

[0015] In the PCD diamond composite reamer, the distance between the PCD diamond shockproof blade 4 and the PCD diamond fine reamer blade 3 is 6mm.

[0016] In the PCD diamond superfine reamer, the PCD diamond anti-vibration blade is a PCD diamond composite blade, the margin is arc-shaped, and there is no back angle.

[0017] The PCD diamond superfine reamer has six PCD diamond anti-shock blades, and the three spaced blades are PCD diamond composite blades.

[0018] The present invention is not only applicable to the six-edged reamer shown in the accompanying drawings, but also includes but not limited to four-edged and eigh...

Abstract

The invention discloses a polycrystalline diamond (PCD) super-finish reamer, which comprises a reamer body and a blade, wherein the reamer body is connected with the blade by welding; the front part of the blade is a hard alloy rough reaming blade; the middle part of the blade is a PCD finish reaming blade; and the back part of the PCD finish reaming blade is provided with a PCD shock-proof blade. Due to the adoption of the PCD super-finish reamer with the structure, shock phenomenon in the processing process is avoided, processing accuracy is enhanced and the service life of the reamer is prolonged.

Description

technical field [0001] The invention relates to a PCD diamond superfine reamer, in particular to a PCD diamond superfine reamer dedicated to an engine. Background technique [0002] The existing PCD diamond reamer has a hard alloy coarse reamer blade at the front and a PCD diamond fine reamer blade at the rear, which can be formed at one time for the stepped forming hole, with excellent and consistent dimensional accuracy, and Surface roughness, but the reamer with this structure often vibrates during processing, which affects the roughness of the processed surface and reduces the service life of the reamer. Contents of the invention [0003] The object of the present invention is to provide a reamer that does not generate vibration during processing, improves processing accuracy and prolongs service life. [0004] In order to achieve the above object, the present invention adopts the following technical solutions, 1. A PCD diamond superfine reamer, including a cutter bod...
