Common Problems And Solving Methods Of Stainless Steel Cutting Oil
Jan 13, 2017

One. Low oil formula is widely used in the market today mainly additives are:

T405A black or Ryukyu +T301 (chlorinated paraffins) +**40 (sulfurized olefin) + canola oil

Advantages: ease of procurement of raw materials, slightly higher olefin sulfide costs aside, other additive prices are lower;

Disadvantages: 1. oil pressure low, resulting in fast tool wear and surface finishing are not up to requirements;

2. high corrosion, resulting in equipment, yellow rust of workpiece, to the environment, employees are also extremely negative;

3. easy to "yellow"


II. Market high-end oil formula of additives are:

Sulfurized lard oil (light) +T301 (chlorinated paraffins) +**40 (sulfurized olefin)

Advantages: in addition to unsaturated acids, vegetable fat, avoid the "yellow" appearance.

Disadvantages: 1. High corrosive, machine, workpiece yellow rust, bad for the environment, operators are also extremely

2. oil extreme pressure still lack access to improved, resulting in fast tool wear and surface finishing


Role of various additives are as follows:

1: curing lard or canola oil + black Vulcanized cottonseed oil: in the initial stage of machining by vegetable fats oils membrane plays a role.

2:301 chlorinated paraffin: working temperature range from 50-350 ℃, so, in the middle stage of cutting, chlorinated paraffins in the dominant position. When cutting pressure, temperature up to a certain height, cottonseed oil antiwear loses effect, chlorinated paraffin extreme pressure began to build.

3: sulfide olefin **40: activity sulfur content high, and copper corrosion sex high, olefin in oil in the is free State of, polar low, and adsorption sex poor, and almost no anti-mill sex, sulfide additives very pressure sex of level depends on three aspects: Polar level, and sulfur of combined way and the sulfur content level; if simple with sulfur content level on judge very pressure sex of high and low, on too one-sided has. Sulfurized olefin main role in cutting oil is formed to prevent cutting the tumor and prevent agglomeration. Machining stages are most prone to problems in two additive connection, transition time, late in the process, because the extreme pressure of sulfurized olefin **40 did not keep up with, so low resulting in surface finishing, tool wear, which also produces sinter.
