Looking atrepparttar advantages of these digital camera printers,repparttar 116106 very first andrepparttar 116107 most significant one is that these printers do not require a computer for their functioning. They haverepparttar 116108 ability of printing directly fromrepparttar 116109 digital camera, which enablesrepparttar 116110 users to take and use them onrepparttar 116111 road too! A few examples of such great printers are Canon's Selphy DS700 and CP330;repparttar 116112 Olympus P-10; Sony's FP30 and EX50; Epson's Picture Mate; and Hewlett-Packard's Photo smart 375. Some digital cameras nowadays enablerepparttar 116113 users to connect them directly to a PictBridge printer using a standard USB cable. And then obtainrepparttar 116114 printed photographs. Another loom is to include memory-card slots right onrepparttar 116115 printer as a resultrepparttar 116116 users do not run downrepparttar 116117 camera's battery while printing.

The above discussion reveals almost allrepparttar 116118 rudimentary yet important information regardingrepparttar 116119 digital camera printers and it is expected that more and more users ofrepparttar 116120 digital cameras would appreciate this fantastic device!

Metal is cut either by movingrepparttar work piece like inrepparttar 116105 lathe or by movingrepparttar 116106 tool like inrepparttar 116107 shaping machine, drilling or milling machine. Clearance angles must be provided to preventrepparttar 116108 tool surface belowrepparttar 116109 cutting edge from rubbing againstrepparttar 116110 work piece. Rake angles are often provided on cutting tools to cause a wedging action inrepparttar 116111 formation of chips and to reduce friction and heat.

Tool Materials 

In order to remove chips from a work piece, a cutting tool must be harder thanrepparttar 116112 work piece and must maintain a cutting edge atrepparttar 116113 temperature produced byrepparttar 116114 friction ofrepparttar 116115 cutting action.

Carbon Steel 

Carbon steel tools even though comparatively inexpensive tend to lose cutting ability at temperatures around 400 degree F (205 degree C).

High-Speed Steel 

High-speed steel, containing 18 percent tungsten, 4 percent chromium, 1 percent vanadium, and only 0.5 to 0.8 percent carbon, permitsrepparttar 116116 operation of tools twice or three timesrepparttar 116117 speeds allowable with carbon steel

Cast Alloys 

Cast-alloy cutting-tool materials containing cobalt, chromium, and tungsten are effective in cutting cast iron and retaining their cutting ability even when red hot.

Cemented Tungsten Carbide 

The hardness of Tungsten Carbide approaches that of a diamond. Tungsten carbide tools can be operated at cutting speeds many times higher than those used with high-speed steel.


Ceramic, or oxide, tool tips consist primarily of fine aluminum oxide grains, which are bonded together. These are very hard.

Cutting fluids 

An overheated tool can become blunt and soft very fast. Therefore very often, cooling fluids coolsrepparttar 116118 cutting points ofrepparttar 116119 tool. This serves to lubricate and cool.

Water is an excellent cooling medium, but it corrodes ferrous materials. Sulfurized mineral oil is one ofrepparttar 116120 most popular coolants as it can both cool as well as lubricate. The sulfur prevents chips fromrepparttar 116121 work from melting on torepparttar 116122 tip ofrepparttar 116123 tool.
