Exceptional Honing Accuracy for Godrej’s Refrigeration Connecting Rod

THE HONING PROCESS – Explained Simply

Here's what you need to know about this precision finishing process:

✅ What is Honing?

A stock-removal finishing process that delivers high bore accuracy and excellent surface finish.

In Conventional Honing, the tool rotates, expands, and reciprocates to improve roundness, straightness, and surface quality.

In Single Pass Honing, the tool passes once through the bore – no reciprocation or expansion, ensuring consistent bore size.

💎 Tool Details

Tools used are diamond-impregnated, barrel-shaped, and preset to progressively larger sizes.

Achieves micron/submicron accuracy – ideal for mass production.

🧩 Applications Perfect for parts like:

Gears

Connecting rods

Rocker arms

Hydraulic valves

Crank cases

Pistol barrels

🔬 Delivers 2-3 micron size repeatability over large batch sizes.

⚙️ CNC Integration

CNC honing machines offer repeatability and precision programming.
