4-4. Feed Gear
Gears and a shaft have been processed for
grinding after a caburizing heat treatment of
Chrom-Molybdenum, and an overload safety device
has been installed to a worm gear of the first
set.
4-10. Electrical Control Box
Each motor of the feed part protects the
machine from overload by using an overload
relay and reverse protection relay.
4-5. Spindle Transmission Device
12-speed transmission and forward/reverse
rotation of spindle with two levers is
possible.
4-6. Feed Transmission Device
6-speed feed transmission with two installed
levers is possible.
4-7. Base
There are three T grooves in the base for
fixing the processed object and a coolant
groove at the boundary of the work surface. At
the bottom where a column is installed, a
coolant tank has been installed as an
all-in-one type.
4-11. Arm Elevation Box
An arm elevation box is installed at the column
sleeve, and it is moved up and down by a motor
through a worm, worm gear and screw.
4-8. Column & Sleeve
The column sleeve is installed to the exterior
of the column. As it is installed vertically to
the base, the arm is operated up and down along
with the back face. As a ball bearing and
thrust bearing are supported at the top part
and a roller at the bottom part between the
column and sleeve, the arm is rotated smoothly.
4-12. Tool Ejector
It is easy to work as it is possible to remove
the tool simply with a push of a button by a
tool ejector motor installed at the top of the
spindle box, and it maintains high precision of
the spindle for a long period.
Usage range
The rotation of the arm should be within the range of 90 (+45 to 45 ) shown below.• ˚ ˚ – ˚
There is a risk that the machine will be overturned.•
Machining should be done within the base of the body.•
Work Method
1. Please place a supplied leveling plate
(200× 120× 20) on the base bolt and lift the
machine to insert it into a hole of the
leveling bolt attached on the base and tighten
with a nut.
2. Please install the machine on the base and
put a level on the top surface of the base to
adjust the balance, and fill the surroundings
of the base bolt with concrete or mortar.
3. Please carry out balance work of the machine
again after the base is solidified completely.
4. Please remove the rustproof oil coated on
the processed surface of the machine after
completing balance work, and coat the slide
surface of each machine part with a machine oil
or equivalent quality oil.
5. Please clamp the arm to the middle position
of the column sleeve after the electrical
connection, and move the spindle box to the
center position of the arm and clamp it to the
column sleeve.
6. Please place a 1/100mm level on the top
surface of the base to adjust the left/right
balance with a leveling bolt. Please tighten
the nut of the base bolt lightly in sequence
after completion, and tighten it firmly after
checking again.
Spindle box
The spindle box will be supplied with oil
through the plug at the top surface of the
spindle box cover, and discharge will be done
through the plug at the bottom part of the
spindle box.
Please adjust the oil supply amount to the
middle position of the oil surface mirror
(during machine operation) in front of the
spindle box.
For gear and bearing parts inside the spindle
box, a force circulation oil supply type
operated by the trochoid pump is used.
During machine operation, please check the
status of discharge frequently through the oil
window installed at the right-hand side of the
spindle box.
Arm Elevation
Please supply the oil and discharge through the
plug at the top and bottom of the arm elevation
box, and for the oil supply amount, adjust the
oil surface to the middle of the oil surface
mirror located in front of the box.
Please refuel with oil by frequently operating
a lever pump on the left-hand side (B3 on page
19).
Please supply with oil for other oil supply
sites according to the daily oil supply table
and oil supply sites diagram.
