Merge White spirit discuss Talk Mineral spirits Merger proposal date June 2008 Mineral Spirits , also called Stoddard solvent CAS 8052 41 3 ref http www.jtbaker.com msds englishhtml s6588.htm Stoddard Solvent Bot generated title ref , is a petroleum distillate commonly used as a paint thinner and mild solvent . Outside of the United States and Canada, it is referred to as white spirit . In industry, mineral spirits is used for cleaning and degreasing machine tools and parts. According to Wesco cleaning supplies Wesco , a supplier of solvents and cleaning equipment, mineral spirits are especially effective in removing oils, greases, carbon, and other material from metal. cn date February 2011 Mineral spirits may also be used in conjunction with cutting oil as a thread cutting and reaming lubricant . Artists use mineral spirits as an alternative to turpentine , one that is both less flammable and less toxic. Because of interactions with pigments, artists require a higher grade of mineral spirits than many industrial users, including the complete absence of residual sulfur. Odorless Mineral Spirits are mineral spirits that have been further refined to remove the more toxic aromaticity aromatic compounds , and are recommended for applications such as oil painting , where humans have close contact with the solvent. In screen printing also referred to as silk screening , mineral spirits are often used to clean and unclog screens after printing with oil based textile and plastisol inks. They are also used to thin inks used in making monoprint s. Mineral spirits are often used inside liquid filled compasses and gauges. A typical composition for mineral spirits is the following aliphatic solvent hexane having a maximum aromatic hydrocarbon content of 0.1 by volume, a kauri butanol value of 29, an initial boiling point of convert 149 F C 0 , a dry point of approximately convert 156 F C 0 , and a specific mass of 0.7 g cc.

It is usually used to apply support to the longitudinal Rotary motion rotary axis of a workpiece being machined. A lathe center is mounted in the tailstock, and inserted against the sides of a hole in the center of the workpiece. A tailstock is particularly useful when the workpiece is relatively long and slender. Failing to use a tailstock can cause chatter, where the workpiece bends excessively while being cut. It is also used on a lathe to hold drilling or reaming tools for machining a hole in the work piece. Unlike drilling with a drill press or a milling machine , the tool is stationary while the workpiece rotates. Holes can only be cut along the axis that the workpiece is set to spin. Usually, the entire tailstock is moved to the approximate position that it will be needed by manually sliding it along its ways. There, it is locked in place and the tool mounted to it is moved with a leadscrew to the exact position where it is needed. When a cutting tool such as a drill bit or reamer is used, the feed is done with this leadscrew. The tailstock quill or extendible portion usually has a Morse taper mount in the end of it to secure the drill or reamer. If the work is heavy the drill may be further secured from turning with a lathe dog as shown in the photo. References Reflist Category Machine tools Metalworking stub Tool stub ... more details

unreferenced date May 2009 Expert subject Engineering date September 2008 In engineering and machining , an allowance is a planned deviation between an actual dimension and a Real versus nominal value nominal or theoretical dimension, or between an intermediate stage dimension and an intended final dimension. The unifying abstract concept is that a certain amount of difference allows for some known factor of compensation or interference. For example, an area of excess metal may be left because it is needed to complete subsequent machining. Common cases are listed below. An allowance, which is a planned deviation from an ideal, is contrasted with a Engineering tolerance tolerance , which accounts for expected but unplanned deviations. TOC Examples of engineering and machining allowances Outer dimensions such as the length of a bar may be cut intentionally oversize, or inner dimensions such as the diameter of a hole may be cut intentionally undersize, to allow for a predictable dimensional change following future cutting, Grinding machine grinding , or Heat treatment heat treating operations. For example the outer diameter of a pin may be ground to convert 0.0005 in mm 3 oversize because it is known that subsequent heat treatment of the pin is going to cause it to shrink by convert 0.0005 in mm 3 . A hole may be drilled convert 0.012 in mm 2 undersize to allow for the material that will be removed by subsequent Reamer reaming . Outer dimensions such as the diameter of a railroad car s axle may be cut intentionally oversize, or inner dimensions such as the diameter of the railroad car s wheel hub may be cut intentionally undersize, to allow for an interference fit interference fit press fit . A part may be cast intentionally too big when it is desired to later machine the surface. This ensures that the roughness that the casting process leaves is removed, and a smooth machined surface is produced. This machining allowance may be e.g. 1mm, but this depends on the size o ... more details

Oilite is a bronze or iron alloy impregnated with an oil lubricant commonly used in bearing mechanical bearing applications. The original Oilite and Oilite Plus are bronze alloys, but the related bearing alloys Super Oilite and Super Oilite 16 are iron based. The name is trademark ed by Beemer Precision. ref Citation title Oilite bearings url http www.beemerprecision.com accessdate 2009 12 17 postscript . ref Composition Oilite is formed using powder metallurgy so that tiny pores are present in the metal. The pores are then vacuum impregnated with an oil to improve the materials bearing ability. ref name mct Citation title Oilite url http www.mct eb.com pdfdown Oilite.pdf accessdate 2009 12 17 archiveurl http www.webcitation.org 5m6Ehu7uf archivedate 2009 12 17 postscript . ref The material holds approximately 20 oil by volume. ref Citation title SAE 841 url http www.nbmmetals.com downloads NBM SAE841.pdf accessdate 2009 12 17 archiveurl http www.webcitation.org 5m66FprSI archivedate 2009 12 17 postscript . ref The most common lubricant is SAE 30 oil. ref Citation title McMaster Carr catalog publisher McMaster Carr edition 115th page 1116 url http www.mcmaster.com catalog 115 1116 accessdate 2009 12 17 postscript . ref Due to the porous structure, machining Oilite poses a special situation. To machine Oilite, the cutting tool must be sharp and stay sharp therefore, tungsten carbide is often used. The sharp tool preserves the open pore structure, because a dull tool would smear the material and close up the pores that are on the surface adjacent to the journal, which is where the lubrication needs to be. Reaming is not recommended, but can be done with a dead sharp tool. Honing and grinding abrasive cutting grinding should not be performed on any surface that is in contact with the journal as these processes always smear the pores. ref name mct class wikitable Chemical composition of various Oilite grades ref name mct Copper Iron Graphite Tin Other elements max.
