3-2 Warming-up Operation of Spindle
3-2-1 Warming-up at the Time of Starting Daily Operation
Caution
It is necessary to keep the bearing lubrication in a good condition for getting the normal
spindle revolution. If the spindle is suddenly rotated at a high speed without warmingup, there is a danger of the oil film being cut and the bearing is burnt stuck. To have
the spindle operated correctly in full capacity, warming up operation is necessary of
which the following should always be practiced practice.
Warming-up before starting daily operation (30 minutes)
[1] 30% of maximum spindle revolution (10 minutes)
↓
[2] 50% of maximum spindle revolution (10 minutes)
↓
[3] 80% of maximum spindle revolution (10 minutes)
Practice warming in the order of [1] , [2] , [3] .
3-2-2 Warming-up When the Machine Was Not Operated for More Than One Week or
Longer
Caution
In case of starting the spindle of oil air lubrication, after it has not been used for more
than one week, warming-up must be practiced taking a longer time than usual, as oiling
into bearing is necessary. In this case, please make sure up practice warming-up
according to the following schedule.
1. #50 - Spindle of 10,000min
Warming-up after the spindle has not been used for more than
one week (minimum warming-up time 4 hours)

3-3 Zero Return Procedures
Be sure to perform manual zero return so that you may set the basic machine coordinate
system after turning on the power.
Display on the pushbutton for zero point direction of each axis flickers.
(1) Operate the mode switching push button for “Zero return”.
(2) Of the push button switches for the axis desiring “Zero return”, press the one with the origin
mark ( ).
(3) By the specified speed of the rapid feed override, the axis returns to the zero point in the
rapid feed speed, and stops at zero point. Then, the zero point position confirmation lamp
of the axis is lit on.
(4) When the lamp lights up, release the switch.
Even when unhanded during decelerated speed movement, the axis stops after zero point
is generated.
The above operations will complete zero return.
Caution
1. Make zero return operations for each axis one by one.
2. When the axis for which zero return is intended is already located close to the zero
point, move axis once to the opposite side of the zero point by about 50mm then
move it again to the direction of the designated zero return point.

4. Manual Operation
4-1 Each Axial Feed
— In case of manual jog feed —
(1) Select the operation mode selector push button switch “JOG”.
(2) Press the FEEDRATE push button switch to set an appropriate feed rate. Pressing the
manual jog feed push button switch for a desired axis, move the machine in a desired
direction.
When it comes to a specified position, release the switch.
(The machine moves only while the switch is pressed.)
Applications : • Warming-up operation
• When bringing close to the zero point
• When cutting by manual operation
• Work rearranging operation
— In case of handle feed —
(1) Select the operation mode selector push button switch “HANDLE”.
(2) Select an axis with the axis selector push button switch.
(3) With the manual handle, you can move the machine by 0.001 mm (0.0001 inch) per
graduation (when 1/1 is selected) or by 0.01 mm (0.001 inch) per graduation (when 10/1 is
selected).
Applications: • When moving the machine by a very fine amount, such as when setting
the zero point by centering a workpiece or fixture
4-2 Rapid Traverse
(1) While pushing the rapid traverse mode switch, press the push button switch for the axis
you want to move at a rapid traverse rate (rapid traverse is applied only while the push
button switch is pressed). At this time, an override of 0, 1, 10, 50 or 100% can be applied
to a specified rapid traverse rate.
(2) Releasing rapid traverse push button switch changes the rapid traverse to normal feed.

4-3 Mounting and Dismounting the Tool
(1) Stop the spindle head at an arbitrary position.
(2) Select one of manual operation modes; JOG, RAPID, HANDLE or ZERO RETURN.
(3) Holding a tool firmly, shift to UNCLAMP the TOOL CLAMP/UNCLAMP selector push button
switch, which is located on the front of the spindle head, and press it.
When the tool has been mounted, if the push button switch is released, the tip of the
drawbar will push the pull-stud bolt, thus removing the tool from a spindle taper hole (hold
the tool firmly lest it should drop). While the tool is unclamped, the yellow lamp located on
the upper left part lights up.
(4) When mounting the tool, eliminate dust completely from the taper section of the tool shank.
Clean the spindle taper hole properly with an accessory cleaner.
(5) Insert the tool shank into the spindle hole, and shift the TOOL CLAMP/UNCLAMP selector
push button switch to CLAMP and press it. The tool is automatically mounted to the
spindle and the yellow lamp lights off.
