EC-1600/2000/3000 - Leveling
EC-1600/2000/3000 - Leveling
March, 2006
Introduction
Leveling of the machine is required to obtain the correct right angle geometry of the machine's X, Y, and Z axes,
and to ensure the correct positioning of the tool changer. Incorrect level will result in out-of-round circle milling,
incorrect linear interpolation, and the possibility that the tool changer may drop tools.
NOTE: Many factors can affect a machine’s ability to remain level — the rigidity of the
floor, the stability of the support under the floor, trains or trucks passing nearby,
seismic activity, and so on. Therefore, until your experience shows how often
re-leveling is required, you should check the machine’s level frequently after
it is installed.
NOTE: Anchoring of the EC-1600 is highly recommended if large, heavy, or tall parts
are to be machined, or if the foundation is suspect.
The leveling includes rough and fine leveling and pursuant geometry checks. The following tools are required to
perform this operation:
• .0005" bubble level • .0005" indicator
• 50T split tool/T-2089 for CT50, T-2088 for BT50 • 50T spindle lock tool/T-2080
• 24" granite parallel • 24" granite square
• Large magnetic indicator base • 1-2-3 blocks
• .0005" caliper
The machines are leveled at the factory, using an electronic level. If not available, use a precision bubble level
with each division equal to 0.0005 inch per 10 inches, or .05 mm per meter, or 10 seconds per div
ision. Before
starting, check the accuracy of your level. Set it on the table on the X-axis and record the reading. Then turn it
180
°
and the reading should be the same. If it is not, the level is out of calibration and should be adjusted before
you continue.
Screw all leveling screws through the base until the base is 4" above the floor (3" pad height + 1" of screw
extending from bottom of base). Note that the condition of the foundation may require different heights at some
leveling screws to achieve level.
