Comparison and advantage of diamond honing rod and ordinary reamer

HDK honing rods are widely used in engine fuel injection pumps, connecting rods, shift forks, hydraulic valve bodies, valve sleeves, valve holes, air bearings, precision gears, mold guide sleeves, air conditioning compressor main and auxiliary bearings, pistons, metering ring gauges, etc. Product fields that require high-precision inner hole machining.

Comparison of honing rod and conventional reamer:

The appearance and structure are similar.

The outer surface of HDK honing rod is plated with a layer of high-grade diamond abrasive of equal grain size. During processing, the exposed sharp corners of these abrasive grains grind the hole wall. The common carbide and PCD reamer use the blade to scrape the hole wall.

The honing rod can achieve micron-level grinding, and the finest honing rod can remove the margin within 1 micron, which is not possible with the common carbide reamer.
