SECTION 2 TRANSPORTATION AND INSTALLATION

The machine is transported by being disassembled into respective component parts after having conducted
break-in and complete examination including actual operation thoroughly at Okuma.
The delivered machine is assembled by staff sent from Okuma. Leave the machine until the Okuma staff visit
your plant although preparation work ahead of assembly including unpacking the packages and removing the
rust-preventive grease are allowed.
In addition, wire ropes are required for transportation and installation of the machine. Please prepare wire
ropes of φ26 mm or more.
Use extra caution when handling the operation box and the control panel.

Site Selection Guidelines

At installation, the following points should be checked in order to ensure high accuracy and perfor-
mance.
•
We recommend appropriate foundation work where the soil is soft or apt to sag after initial
installation.
See FOUNDATION PLAN and FOUNDATION REQUIREMENTS for reference.
•
The installation site should be kept as far as possible from vibration sources, such as roads,
stamping/press type equipment, or planer type machine tools. If nearby sources of vibration are
unavoidable, dampening pits around the machine foundation, for example, should help lessen
vibrations.
•
Where there are high-frequency power generators, electric discharge machines or electric
welding machines around or when power is supplied from the same shop power distributor
panel, electrical interference may cause NC malfunctions. For assurances, consult our service
engineer dispatched for the installation.

Foundation Requirements

•
Foundation requirements vary depending on the characteristics of the sub-soil. Under any soil
conditions, it is important that sub-soil should be well compacted to keep the foundation from
unsettling once the machine has been installed.
•
Where sub-soil is too soft, it is necessary to drive concrete piles into the sub-soil.
•
The Foundation Plan attached to this Manual is prepared for laying a typical concrete founda-
tion specifically for the machine. The concrete thickness or depth should be determined in
terms of the ground condition in each case.
