Description

Patented Dec. 3, 1946 CUTTING OIL Thaddeus Williamson Culmer, Robinson, 111., as-
signor to The Ohio Oil Company, Findlay, Ohio, a corporation of Ohio No Drawing. Application August 13, 1943, Serial No. 498,577
2 Claims.
This invention relates to'cutting oils and. more particularly to a cutting oil which has been treated to prevent staining.
With present day oils which are of the type used for cutting, particularly those employing mineral blending oils having a maximum viscosity of 125 at 100 S. U., there is a tendency for the oil to stain not only the cutting machinery but also the work. This is objectionable not only because of the staining of equipment but also because the work piece produced may he rejected by an inspector in view of the stain. Most cutting oils are compounded from chlorinated sulphurized bases and it would appear that during operation the sulphur breaks out of the combination in an active form and. reacts with the metal to form a stain of various degrees of intensity.
An object of the invention is to provide a cutting oil which will not stain the work or the machinery. A further object is the addition of a fatty oil or compound of the glycero phosphate type, for example, lecithin to a cutting oil compounded from a chlorinated sulphurized base such as sperm oil and petroleum neutral oil for the prevention of stains on the surfaces of metals with which it comes in contact.
While the amount of lecithin or other products which can be added may vary to suit particular cases, in my preferred form T 6 to 1% is sufficient. In preparing the oil 1000 pounds of lecithin and 56 gallons of 100/100 neutral oil or sperm oil are placed in a steam jacket mixing kettle provided with paddles or other agitators. Heat up to 150 F. is applied and as soon as the lecithin has softened sufficiently the mass is agitated until the lecithin has been completely dispersed or dissolved in the oil.
This solution may then be stored and added to the cutting oil as it is made. Approximately .35 of a gallon is added to each gallon drum of cutting oil and rendered homogeneous therewith by agitation. This results in a final cutting oil which contains approximately 0.5% of lecithin by weight.
The final product will not stain or discolor the work or the cutting machinery and the free sulphur is taken care of by the lecithin so'that no sulphide coating appears on the metal.
I claim:
1. A chlorinated sulfurized sperm oil cutting oil which yields active sulfur under conditions of normal use, said cutting oil containing from about 0.5% to about 1.0% of lecithin to prevent such active sulfur from causing'stains.
2. A cutting oil compounded from chlorinated sulfurized sperm and petroleum oils from which under conditions of normal use active sulfur breaks out, said cutting oil containing from about 0.5% to about 1.0% of lecithin-to prevent such active sulfur from causing stains.
