Metal cutting fluid testing standards revealed! Be sure to collect!
March 04, 2023
There are relatively few inspection standards for metal cutting fluid in China, and only a few can be consulted. However, cutting fluid is often used in the process of metal cutting and polishing. It can be said that metal cutting fluid plays a key role in the whole workpiece processing, quality completion, surface roughness, etc. Today, we can find out the inspection indexes specified in the inspection standard of metal cutting fluid for you to explain in detail.
1. The test items specified in Synthetic Cutting Fluids (GB/T 6144-2010) mainly include: 1) Appearance inspection index requirements Requirements for liquid cutting fluid: no layering, no precipitation and uniform liquid concentration Requirements for paste cutting fluid: no precipitation of heterogeneous substances, uniform paste Requirements for shrinkable solid powder: uniform powder without hard lumps and soluble in water 2) Storage stability test refers to the requirement that there is no layering, phase change, gelatinous, etc., and it can be restored to the original state after the test 3) Transparency detection refers to the requirement of transparency or translucency 4) The corrosion test shall be conducted with cast iron, copper and aluminum alloy test pieces 5) The anti-rust test requires that the temperature is 33-37 ℃, and the single-piece anti-rust test needs to pass the 24-hour inspection to be qualified, and the laminated anti-rust test needs to pass the 4-hour inspection to be qualified 6) In addition, the test items of synthetic cutting fluid include defoaming property, pH value, surface tension, PB value of maximum non-seize load, adaptability to machine tool paint, concentration of nitrogen dioxide and other indicators 2. The inspection items specified in JB/T 7453-2013 Semi-synthetic Cutting Fluids mainly include: 1) Appearance inspection index requires uniform transparent liquid 2) The storage and transportation stability test index shall be free of discoloration, delamination and uniform transparent liquid 3) The phase state detection index shall be uniform, transparent or translucent 4) The corrosion test shall be conducted with cast iron, copper and aluminum alloy test pieces 5) The stability test of diluent requires no oil or soap precipitation 6) The anti-rust test requires that the temperature is 33-37 ℃, and the single-piece anti-rust test needs to pass the 24-hour inspection to be qualified, and the laminated anti-rust test needs to pass the 4-hour inspection to be qualified 7) In addition, the test items of semi-synthetic cutting fluid include defoaming property, pH value, surface tension, salt tolerance, hard water adaptability, extreme pressure PD value, interfriction, adaptability to machine tool paint and other indicators 3. The test items specified in GB/T 31469-2015 Cutting Fluids for Semiconductor Materials mainly include: The inspection indicators of cutting fluid for semiconductor materials are relatively few. The appearance inspection indicators require colorless or yellowish transparent liquid. In addition, the inspection items include viscosity, density, chroma, pH value, water content, conductivity and other indicators. In fact, there is also a local standard DB22/T 467-2009 "Clean Synthetic Metal Cutting Fluids" in the metal cutting fluid testing standard. Because it is not authoritative, we will not repeat it here. There are also several relevant standards for metal detection methods, specifically: SN/T 2704.1-2010 Cutting Fluids and Machine Tool Excretions Part 1: Determination of Phosphate Radical Ion Chromatography SN/T 2704.2-2010 Cutting Fluids and Machine Tool Effluents Part 2: Determination of Chlorine and Bromine Ion Chromatography SN/T 2704.3-2010 Cutting Fluids and Machine Tool Excretions Part 3: Determination of Nitrite Ion Chromatography SN/T 2704.4-2010 Cutting Fluids and Machine Tool Discharges - Part 4: Determination of Mercury - Mercury Meter Method The foreign testing standards for metal testing fluids include JIS K2241-2017 Cutting Fluids DLA VV-C-846 C-2005 Emulsified Oil Cutting Fluids ASTM E2148-2011 Standard Guide for the Use of Documents Related to the Health and Safety of Metalworking or Metal Cutting Fluids, etc.
