1. Introduction: The mechanical properties such as hardness, abrasion resistance, tensile strength is very important for cutting tools. The cryogenic treatment of metals has been used extensively for many years for various applications such as stabilization of the size of meters and a precision machined part with temperature changes, the elimination of internal stresses, improving the cold treatment and lasting hardness . Cryogenic metal parts means that these components in a certain percentage to a cryogenic temperature (-80  C), maintenance of these components that lower temperature for a certain period of time after the admission of these parts into a particular type of warming warming to room temperature. So the key variable cryogenic treatment: a. Cooling.b height. The lowest temperature will be maintained for a certain duration.c. The duration for which the model will remain at the lowest temperature.d. The rate of warming (Chillar, Agarwal. 1995) cryogenic treatment has been applied successfully to steel to improve mechanical properties. This is because the processing of almost all the retained austenite to martensite in steel making steel more resistant.2 wear. Literature Survey: Test of cryogenic treatment was found in 1937 in the Soviet Union (Carry and Robert, 1980). The metal is cooled to cryogenic temperatures (-80  C), soaked for a longer period and warmed to room temperature at a preset rate, the lattice structure of atoms change due to stress revived during the cryogenic treatment. In the case of non-ferrous metals, soft, hard Austenite FCC structure becomes strong and structured BCC martensite more difficult. Apart from this, a broad reflection of the newly formed ETA Carbides (responsible for increased wear resistance) in the hard structure Mart Side induces a dense network of theories Zhmud structure.Some (1980) are: a. cryogenic treatment is effective for mild to moderate and appropriate tool.b. The soaking time (5 minutes to 10 hours) had no effect on the tool life.c. A decrease in the life of the tool within 5-7 days after treatment and increases again with repeated treatment can be performed by treatment.Cryogenic different methods.One of these methods is a Cryo-therapy room and an additional supply system with liquid nitrogen. In this set-up of cryogenic treatment of the instrument was carried out by indirect cooling and no direct contact with liquid nitrogen. Cryotherapy is a container of double wall stainless steel and space cluttered with polyurethane foam. The upper deck has a stainless steel double end shaft motor mounted fan in the center. Liquid nitrogen, the valve connecting the pressure pads and feed through outlet connections all mounted on the top flange.Below the top is mounted a cylindrical tank of liquid nitrogen buffer for collection and evaporated water is discharged through a ventilation tube. The axis of the fan motor assembly passes through the reserve tank and the fan mounted on both sides. A copper disc is attached to the bottom of the storage tank to enhance heat transfer. Fans of aluminum to the bottom to ensure the forced cooling of the space inside the Cryo-therapy room. The sample stored in stainless steel tray can be cooled in two ways: i. A circulating fan located in the reservoir, getting forced convection of cold liquid nitrogen stored in the reservoir down onto the sample. The cold gas toward the bottom of the chamber is cooled and radially moves sideways. These gases re-enter the fan zone by the opening of the slots in the aluminum fins. If you must loop current is at the chamber.ii. Part of the liquid nitrogen stored in the reservoir is circulated on the shroud of thermo-siphon effect. To facilitate a copper tube connecting to the storage tank and is welded to the outer wall of the shroud over the whole length. A solenoid valve operated by a PID controller with predetermined points, liquid nitrogen is used to regulate the supply to the room. The sample temperature is measured by the temperature method can be used sensors.Another fridge with ethanol and dry ice as a coolant for the cryogenic treatment. The sample in question was placed in a thermocol box clean and dry. The model with thermocol box were stored in a refrigerator for the duration of 12 hours to reduce the temperature of the
