化学气相沉积金刚石刀具及其加工方法
摘要：
本发明涉及一种化学气相沉积金刚石刀具及其加工方法。所述加工方法包括提供由硬质合金制成的基体和由化学气相沉积金刚石制成的刀片；焊接刀片至基体的端部；磨削刀片去除刀片焊接至基体的端部后过多的余量；及激光切割刀片露出在避空面的切削面，使切削面中的第一后刀面与前刀面之间的夹角的余角为10‑12°，并使切削面中的第二后刀面与前刀面之间的夹角的余角为所述第一后刀面与前刀面之间的夹角的余角的两倍。上述化学气相沉积金刚石刀具及其加工方法，刃口的崩口在2μm以内，且加工效率较高，能满足对于刀具的加工质量和速度的要求。
摘要（英）：

The invention relates to a chemical vapor deposition diamond cutter and a processing method of the chemical vapor deposition diamond cutter. The processing method comprises the steps that a base body prepared from hard alloy and a blade prepared from chemical vapor deposition diamond are provided; the blade is welded to the end of the base body; the blade is ground to remove the excess residue left after the blade is welded to the end of the base body; and the cutting face, exposed in the clearance face, of the blade is cut through laser light, the complement angle of the included angle between the first rear cutter face and the front cutter face in the cutting face is made to be 10-12 degrees, and the complement angle of the included angle between the second rear cutter face and the front cutter face in the cutting face is made to be two times that of the included angle between the first rear cutter face and the front cutter face. According to the chemical vapor deposition diamond cutter and the processing method of the chemical vapor deposition diamond cutter, the dent of a cutting edge is within 2 micrometers, processing efficiency is high, and the requirements for the processing quality and speed of cutters can be met.
