Functions of the Lubrication System in Cold Forging Machines and Industry-Specific Selection Standards
Release date:
2026-05-15
The lubrication system is a core component that ensures the stable operation of a cold heading machine. Its primary functions are to reduce friction between the die and the wire, as well as between moving parts; to cushion the impact pressures generated during cold heading; and to dissipate the heat produced during machining, thereby slowing down die wear and machine aging.
The lubrication system is a core component that ensures the stable operation of cold upsetting presses. Its primary functions are to reduce friction between the die and the wire stock as well as between moving parts, to cushion the impact pressures generated during cold upsetting, and to dissipate the heat produced during machining, thereby slowing die wear and machine aging. Commonly used in cold upsetting operations, lubricants and cold‑upsetting oils feature viscosities and extreme‑pressure properties tailored to metal plastic forming, helping to prevent surface defects such as galling, cracking, and burrs.
In the industry, lubricant selection is tailored to the wire material: carbon steel, stainless steel, and alloy steel each require distinct oil formulations, with stainless steel demanding superior extreme-pressure lubrication performance during forming. During routine production, it is essential to regularly clean impurities from the oil system and monitor pump delivery pressure to ensure smooth oil circulation. Proper lubrication management not only enhances workpiece surface quality but also effectively extends the service life of wear‑prone components such as dies, bearings, and slides, thereby reducing factory production and maintenance costs.
