3. Operational Procedures

3-1 When Starting the Machine

(1)Turn on the supply power Switch.

(2)Turn on the power switch on the electric cabinets

(3)Press the POWER ON push button switch located on the upper part of the main operation panel.

Caution

The main panel and NC cabinet are enclosed lest the open air should enter directly. Therefore, do not leave each door open for a long time while the power is turned on. Check on the display and that cooling fan motors inside and outside the cabinet are started.

(4)Release EMERGENCY STOP button on the main operation panel.

(5)Press the STANDBY push button switch located of the main operation panel. (A green lamp lights up.)

(6)Before starting daily operation, reciprocate the X, Y and Z axes several times. (When this is done, be careful not to have the axes overtravelled.)

(7)Return each axis to the zero point (refer to the description for zero return). By performing zero return, a basic machine coordinate system is set and stored stroke limits are made effective.

(8)Turn on the conveyor switch.

Caution

Do not make operation under the state that massive chips are cast in the trough.

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.

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.
