Use of equipment of numerical control lathe normally must satisfy following requirements, the machine tool is located wave motion of power source voltage is small, environmental temperature under 30 photograph show degree, opposite temperature is less than 80% . 1, the position of environmental requirement machine tool should be far from Zhen Yuan, should prevent sun the influence of direct illuminate and heat radiation, avoid the effect of moisture and air current. If there is Zhen Yuan near the machine tool, criterion machine tool all around should set vibration isolation channel. Machine what affect a machine tool directly precision and stability otherwise, will make electronic component contact undesirable, malfunction, affect the reliability of the machine tool. 2, power source asks installation of lathe of ordinary numerical control is in machine job shops, not only environmental temperature change is big, use condition is poor, and all sorts of Electromechanical equipment are much, cause electrified wire netting wave motion is big. Accordingly, install the position of numerical control lathe, voltage of need power source has strict control. Wave motion of power source voltage must be inside limit, and maintain relative stability. Can affect the regular job of numerical control system otherwise. 3, the environmental temperature of lathe of temperature condition numerical control under 30 photograph show degree, opposite temperature is less than 80% . Generally speaking, numerical control is electronic-controlled box interior sets a fan or cold fan, in order to carry electronic element, especially temperature of central processor job constant or temperature poor change is very little. Exorbitant temperature and humidity will bring about life of control system component to reduce, cause breakdown increase. The heighten of temperature and humidity, dirt grow in quantity can be in integrated circuit board generation felt, bring about short circuit. 4, when user of normative use machine tool is using a machine tool, do not allow to change the parameter that controls set of the manufactory inside the system at will. The set of these parameter matters to a machine tool directly feature of each component trends. Only numerical value of clearance compensating parameter can give according to actual condition adjust. The user cannot change at will machine tool accessory, if use,exceed the hydraulic pressure chuck that the manual sets. The manufactory is when setting accessory, mature of each link parameter match. Change blindly those who cause each link parameter do not match, cause the accident that estimation is less than even. The pressure of oil cylinder of tailstock of tool carrier of chuck of use hydraulic pressure, hydraulic pressure, hydraulic pressure, hydraulic pressure, should be in allowable inside stress limits, do not allow to rise arbitrarily.
