1.1 Selection of Machine Installation site
1)
Temperature at the place of machine installation
Machine performance may be affected due to an irregularity of the lubrication system if
the temperature is lower than the temperature range allowed for machine operation, or
due to reduced cooling capacity of the oil cooler if the temperature at the place is higher.
Since the machine’s precision can be directly affected by displacements of the
respective parts of the machine resulting from a temperature change, the place of
installation needs to be carefully selected after examining it from various angles, in order
to ensure that the in-room temperature is maintained evenly.
① Avoid direct sunlight when selecting the place of machine installation.
▪ If unavoidable, consider installing awning screens, etc. to help reduce the
machine’s exposure to direct sunlight.
② Avoid the following places: a place near a factory entrance; a place where a
temperature change is likely due to radiant heat from other machines or walls or due
to the flow of air from an air-conditioning unit.
▪ If unavoidable, consider installing screens to help shut off areas subject to outside
air or heat from the surrounding area.
③
In the event of a low ceiling or when several units are installed in a confined space, a
temperature difference between the upper and lower parts of the space concerned
may occur.
▪ If unavoidable, consider using a method of forcing
the movement of air between the
upper and lower parts.
※ Allowable temperature range for machine operation:5∼40℃(humidity:30∼75%)
2) Vibration around the place of machine installation
The machine needs to be installed in a place as far away as possible fro
m any source of
vibration such as a road or a press machine where there is a lot of vibration.
▪ If unavoidable, consider installing a Damping Pit around the foundation surface of the
machine.
※ Note) Vibration regulation value on general worksites : 0.8mm/sec
3) Machine installation floor
The floor on which the machine is installed should be firm, secure and flat.
▪ Appropriate foundation work should be conducted if the place where the machine is
installed for the first time consists of soft ground or is prone to subsidence.
▪
If the ground is too weak and soft, drive concrete piles into the ground to reinforce it. In
this case, consult with a professional company before conducting the work.
4) Other cautions
① In addition to the place of installation of the main machine body, secure sufficient
space for door opening, the chip conveyor’s length, and maintenance activities.
② Select a place that is not exposed to dust or strong corrosive gases.
