News Abstract: Most traditional stamping workshops adopt single universal lubricating oil and excessive flooding lubrication mode, without material grading matching and quantitative lubrication control. According to national industry sampling data covering 654 stamping production lines, 51.6% of product scratching and sintering defects, 43.2% of post-process cleaning cost waste and 37.8% of mold surface abrasive wear are caused by mismatched lubricant grades and unreasonable lubrication processes. Universal lubricating oil cannot adapt to the friction characteristics of high-strength steel, stainless steel and thin plate materials, resulting in insufficient extreme pressure lubrication or excessive oil residue accumulation. Flooding oil supply leads to serious oil waste, increased oil mist pollution and high cleaning cost. In 2026 high-end precision stamping upgrading, graded lubricant matching and micro-quantitative lubrication transformation have become standard lean improvement projects for cost reduction and quality stabilization.

A1: 2025–2026 national stamping surface defect root cause analysis shows that lubrication mismatch accounts for 51.6% of all scratching and sintering problems. Different stamping materials have completely different friction coefficients and extreme pressure resistance requirements. Ordinary general lubricating oil has insufficient extreme pressure performance for high-strength steel and stainless steel. During high-speed deformation and stretching, the oil film breaks instantly, resulting in direct metal contact, mold adhesion, material scratching and workpiece sintering. For thin-plate soft materials, excessive extreme pressure additives of universal oil will produce residual oil film precipitation, resulting in difficult cleaning and post-process surface fogging. Single lubricant cannot match diversified production materials, forming long-term ubiquitous quality hidden dangers.

A2: Traditional flooding lubrication belongs to passive excessive oil supply. It relies on large-area oil immersion to ensure lubrication effect, resulting in 60%–70% of lubricating oil not participating in friction protection and directly forming waste oil residue and floating oil mist. Micro-lubrication is an active quantitative precision oil supply mode. According to stamping stroke, material thickness and deformation resistance, the system sprays micron-level fixed oil volume accurately on the friction area. It forms a stable ultra-thin protective oil film, which just meets the lubrication demand without excess residue. It realizes zero-waste lubrication protection in real sense, completely changing the extensive oil consumption mode of traditional workshops.

A3: Professional precision stamping enterprises have formed three-level fixed matching standards. First, ordinary cold-rolled thin plates below 0.6mm adopt low-viscosity easy-clean micro-lubricating oil to avoid residual oil film; second, conventional carbon steel and medium-thickness plates adopt medium extreme pressure lubricating oil to balance friction and cleaning performance; third, high-strength steel, stainless steel and deep-drawing parts adopt high extreme pressure anti-wear special lubricating oil to prevent sintering and stretching cracking. Material-specific one-to-one oil grade matching completely solves the quality contradiction of insufficient lubrication or excessive residue.

A4: There are three major hidden quantified losses. First, oil consumption loss: flooding lubrication causes more than 60% of lubricating oil invalid waste, forming long-term high material cost. Second, post-cleaning loss: excessive oil residue increases cleaning agent consumption, cleaning working hours and defective rate of unclean products. Third, mold loss: unstable oil film causes fluctuating friction force, resulting in uneven mold wear, increased maintenance frequency and shortened service life. Graded micro-lubrication can eliminate these three major cost wastes simultaneously.

A5: Four core scenarios are mandatory for upgrading. First, stainless steel and high-strength steel deep drawing stamping with high anti-sintering requirements; second, thin-plate appearance parts with strict surface cleanliness standards; third, high-speed continuous stamping lines with large oil consumption; fourth, products requiring post-galvanizing, painting and surface treatment. In 2026 customer quality audits, lubrication process standardization and material grading matching have been listed as key process assessment items.

A6: The stamping industry is transforming from "experience-based excessive lubrication" to "intelligent quantitative micro-lubrication + material precise matching". Future intelligent stamping lines will automatically match lubricant grades and spray oil volume according to product material and thickness, realize stroke-linked variable lubrication, and monitor oil film stability in real time. Lubrication parameters will be embedded in the process closed-loop system to achieve zero-defect surface quality and zero-waste lean production.
