D. INSTALLATION D-1 Foundation and Leveling

Leveling of the machine is very important not only to ensure but also to prolong the life of the machine. Hence, close attention should be paid to its leveling.

Procedure of leveling is as follows:

1. Install the machine on the laid foundation according to the foundation drawing.

2. Place a level gauge on the table as shown in the figure below. The leveling should be carried out, referring to the gauge.

3. As soon as the level is obtained, fill the bolt pits with concrete.

4. When the concrete is hardened, tighten the foundation bolts.

Level of the machine might not be obtained by only one adjustment, in particular, when the machine has remained packed or has been left in improper conditions for a long period of time. In the case like this, check the level and readjust it three or four weeks after the first adjustment. Slideways and other metal parts of the machine is covered with anti-rust oil when it is packed in the seaworthy case. Use non-corrosive and non-flammable cleaning fluid. Then apply some oil to prevent rust.

D-2 Machine Environment

To obtain the best performance of the machine, special attention should be paid to the ambient temperature, dust, vibrations, etc.

※ Ambient temperature fluctuation affects machining accuracy considerably. Consequently, avoid exposing the machine to the direct sunlight, and keep it away from hot or cold air stream from ventilators and the heat transmitted from neighboring machines.

※ Avoid installing the machine in a dusty or polluted environment, because dust and air pollution may cause an intense abrasion to slideways and electric devices.

※ The numerical control system is particularly is particularly vulnerable to dust and humidity, so that installation environment should be kept as clean as possible.

※ The machine should be installed where no vibration is transmitted from neighboring machines.

D-3 Electric Wiring

Wiring between the machine and its equipment has been accomplished by us before delivery. Be asked to wire from the power source (200V or 220V,3phases) to the electric box in your shop. Use gauge line for the wiring. (Max. power supply capacity : 20KVA)

After turning the power on, make sure that the electric phases are properly connected to the electric box and to the CNC, and that the rotating direction of the coolant pump motor are correct.

READ INSTRUCTION CAREFULLY BEFORE OPERATING

PRODUCTION TURRET CENTER DRILLING MACHINES

When this manual was printed, the information given is current. However, since we are constantly improving the design of our machine tools, it is possible that illustrations, and descriptions may vary from the machine you received. That means the machines you received is the latest improved model better to fulfill your requirements. If thoroughly read, will give you valuable information in the operation , installation and servicing of the model STC-12 series.

The manual can be used for reference, it is necessary to make minor adjustment for maintenance personnel and operators that have dealings with the model STC- 12 series.

The model STC-12 series machines is built of extreme ease and safety of operation, the finest manufacturing and used high quality materials with the proper care and use you are assured trouble-free, accurate and economical operations for the life of the machine. LIFTING THE MACHINE

It is advisable to lower slide before remove machine from the skid by crane. When lifting the rope or cable should be arranged as shown figure and checking to see whether the correct balance is obtained. Then insert pads of soft cloth between rope and machine edges. The net weight of this machine approximate 1,140 lbs. so the rope or cable must be has 1,500 pounds standing weight capacity. A. INSPECTION AND CLEANING OF MACHINE

An inspection to find some damaged portion which might have been caused by shock during the transpiration, as well as to find if there are some parts, standard tools and equipment missing, should be made after arrival of machines in your plant. Use cloth or brush to clean STC-12 machine, DO NOT clean machine with compressed air, if not, will reduces the life of the machine as small particles of dirt and other foresight matter maybe forced past seals and wipers into slides and bearing or gear box. After machine has been properly located level, wash with a good grade of grease solvent off all shipping grease, oil, grit and dirt accumulated in transit.

B. FOUNDATION AND INSTALLATION

The production turret center drilling machine will operate without the need of special foundations but the accuracy of machine more concerning with the foundation and installation of the machine. For this reason, a perfect foundation with proper thickness and pressure-enduring space must be provided according to the ground nature. In general case, a thickness of 200M (8”) is considered to be enough.

C. MOUNT SPINDLE GUARD

D. WIRING

Check motor voltages and connect the wires of the power source to the terminals (R.S.T) which is in the electric switch case. Motor should rotate correct direction (arrow in belt guard indicate correct direction of rotation). If motor does not turn in the correct direction, disconnect electric power source, and interchange any two leads.

！WARING: DO NOT INDEX THE TURRET, BEFORE CHECKED DIRECTION OF THE MOTOR. E. LUBRICATION

Special care on lubrication should be taken to maintain the service life and performance of the machine for a long period. For this reason, must used a high quality or equal oil and checked periodically to assure they are filled to the proper level on the oil gage, pour oil hole is located between No.4 and No.5 spindle on perimeter of turret head.

LUBRICTION INSTRUCTION

Part Period Lubricant turret head and gear box Renewing oil after the frist MOBIL DTE OIL 300HRS, and then once after (ESSOTERESSO 43) every 1,000HRS ways and other fitting twice a day MOBIL VACTRA OIL NO.2 (ESSO FEBIS K53)

※ CAUTION: Renewing oil after the first 300HRS drain oil out of the turret head and gear box, wash out with solvent, refill to proper level with correct high quality oil, draining plug are on perimeter of turret head and at bottom of gear box.

F. SPINDLE SPEED SELECTION

The spindle speed sequence of the model STC have two ranges (high and low) accomplished through the 2:1 ratio motor-and the use of a two-step belt drive location at rear of machine, in each of these ranges and speeds per spindle is available automatically through the use of a two-speed motor. These spindle speed changes are furnished complete with:

1.A high and low speed range is provided by a two-step "V" belt drive. To change speed range, remove belt cover at rear of machine, loosen C-02-14 socket head cap screw and turn adjust eccentric wheel part No.C-02-11 (see parts list assembly) until belt is loose enough to be changed. After changing, turn the adjust eccentric wheel back and tighten screw. ！ WARNING: It is most important that toggle switch located at front of welded steel cabinet is at "A" position for "A" pulley and "B" position for "B" pulley. If incorrectly set it, will unfavorable affect indexing speed and operation of machine.

2. Spindle speed per-selected The speed of each spindle can be allow you to preselect, part No.C-03-70 switch box cover is located at the top of slide body (see parts list assembly). Has a touch cam per spindle in the switch box cover, on outside of the touch cam have "H" and "L" indicate mark. "H" for high motor and "L" for low motor,(speed number see a end chart plate).

3. Provision is made so that the turret head will always index at a constant speed, a speed which we have provides maximum life and production. Located at the top of the slide body part No. C-03-95 is a sealed micro-switch, the part No. is C-05-64. Machine will change speed into indexing speed about 19MM (3/4") from top of travel stroke. This should be allowed for when setting up. If you find that the turret head indexes very quickly or very slowly, it will indicate that micro-switch part No. C-05-64 is not operating correctly, or that toggle switch part No.C-05-88 at front of welded steel cabinet is not incorrect position, you must inspect and replace correct position.

G. SET UP PROCEDURE

1. The spindle speeds should be selected to suit for each particular job, depending on material, type of cut and tool to be used. Decide to what sequence you wish to mount your cutting tools on the turret head, not only from the operations to be perfromed, but also from the spindle speeds available at each station. 2. Try to keep the overhang of all tools as equal as possible to eliminate lost motion required to bring the tools to the work. Use spindle extensions to uniform tool length. They are available in lengths of. 1" , 2" , and 3" . Mount cutting tools in proper sequence in the drill chucks, taper sleeves, tapper etc. 3. Set turret head to perfect working clearance over the work by raising or lowering body on columns. Loosen the clamp bolts (part No. C-01-24) and raise or lower by hand wheel at top of columns. When proper height is reached, re-lock in position. 4. Index machine through working cycle, setting depth stop screw at each position to suit the work. The turret will index automatically when slide body is raised to the top position, actuating the index machanism. To repeat operations at one spindle without indexing, simply avoid raising the slide body to the extreme top. 5. To skip a station, or stations, first adjust depth- stop screw down to shortest stroke to prevent feeding an un-used station. A short downward and upward strove of feed handle will allow turret to index to next station. 6. Set the depth for each spindle by adjusting stop blocks for each spindle. Use scale on right of column for rough setting. Move the stop block (part No. C-03-78) to closest position to travel stop block (part No. C-03-5). Make final adjustments by loosening set screw, turning adjusting screw (part No. C-03-79) until it contacts the travel stop block, then tighten set screw.

！WARNING: IN ORDER INSURE ACCURACY SHOULD BE FREE OF DIRT IN THE CHUCK MOUNTING FACE AND SPINDLE SHOULDER. miaximum distance from center of turret to tip of tool should not exceed 330MM (13”) for safe clearance within the spindle guard.

H. SPEED CHANGE

If you do not get the spindle speed you have pre-selected in switch box (part No. C-03-70) when a particular spindle indexes into operating position, this indicated that the switch box, loosen socket head screw, turn control drum until the turning ring is centered on the front of the machine, or until the microswitch is actuated, then tighten socket head screw.

I. ADJUSTMENTS

FEED HANDLE: Counter weight spring adjustment 1、To wind spring increase or decrease counter weight action: a、remove safety screw M6x12 ( C-03-87) on face of slide body. b、slide should be lower until rack is out of engagement with feed handle gear.

！ WARNING: In order to prevent spring broken and cause injury to maintenance men.You are sure that the feed handle (part No. C-01-38) is held to prevent rapid unwinding of the spring (part N0.C-01-35).

c、turn feed shaft (part No.C-01-44) counter clockwise to increase tension on spring and clockwise to decrease spring tension.

！WARNING: Turning of shaft will make considerable difference in spring tension and counter weight.

d、replace safety screw (part No. C-03-87). 2、SAFETY CLUTCH MACHANISM: Refer to part list drawing. You will find that the turret head indexes sluggishly, or does not index completely during the index cycle, and you are sure that nothing is binding, it will be necessary to tighten the safety clutch as follows: a、to turn off the motor and downward slide body to lowest position, exposing bearing (C-03-25) and adjustment lock nut (part No. C-03-27). b、tighten lock nut (part No. C-03-27) one-half turn.

3、REPLACE BROKEN COUNTER-WEIGHT SPRING a、lower slide body until rack is out of engagement with feed handle gear.

！ WARNING: In order to prevent spring broken and cause injury to maintenance men, You are sure that the feed handle(part No. C- 01-38), is held to prevent rapid unwinding of the spring (part No. C-01-35).

b、remove (3) SOC. HD.CAP screw (part No.C-01-49), and pull feed handle assembly out of saddle assembly. c、remove *6x55 spring pin(partNo.C-01-40)and disengage lever handle block (part No. C-01-39) from feed shaft (No. C-01-44). d、slide body feed shaft (No. C-01-44) out of spring housing (N0. C-01- 34). e、place a buriag bag over the spring housing and pull broken spring out of housing. (Bag can protects personnel from injury as spring unwinds). f、insert new spring into the spring housing, making sure that "HOOK" on outside coil of spring engages dowel pin (3/8"x2"). When spring is wound, the feed shaft turns counter-clock-wise, so be sure spring is inserted into spring housing correctly.

！WARNING: Remove "KEEPERS" around spring only as it is inserted into the housing.

g、Reassemble feed shaft and spring with (3) M8X40 SOC. HD CAP screw (part No. C-01-44). h、Mount feed handle spring housing (part No. C-01-34) to the shaft. i、Mount feed handle assembly to saddle.

J. WIND SPRING

1、Turning feed wheel counterclockwise 8 turns before ringing rack and rack gear. ！WARNING: Do not let go of feed wheel as it spring to unwind and break. 2、Re-engage rack and rack gear by moving slide body upward. ！WARNING: Spindle should not be adjusted so tightly that the slide body will ret and index automatically.

K. FAILURE TO INDEX:

Refer to drawing of part list assembly. If the turret does not index when machine slide body is brought to top position with motor running, adjustment is necessary. 1. Check to see if the have at front of machine slide body (part No. C-03-95) contacts the bottom of depth stop driven shaft (part No. C-03-65). If chips are lodged here, it will prevent slide body from moving into index position. These 2 surfaces should be in contact when slide body is at top of stroke. 2. If condition 1 is correct, check if push lever (part No. C-03- 54) is in contact with push lever actuating shaft (part No. C-01-20). 3. If push lever actuating shaft is not in contact when slide is in "UP" position: a. loosen nut (part No.C-01-19). b. advance shaft in small increments, until turret indexes with slide body in upper position. c. lock nut.

！WARNING: over-advancement of push lever actuating shaft will cause machine to double- index.

L. TURRET HEAD:

Refer to drawing of part list assembly. 1. If turret head gives indications of being loose against the slide body face, or an oil leak develops at bottom of turret between slide body and turret head, it indicated a loosening of the turret stud bolt (part No.C-04-1). To adjust, remove "S" plate No.C-04-38 on face of turret and using socket hex, wrench, tighten nut No.C-04-5 slightly. 2. To remove turret, remove nut No.C-04-5, spring No. C-04-4 bearing No. C- 04-3 and "O" ring No. C-04-37 and pull turret head straight out.

！ WARNING: Make only a small adjustment, as tightening the nut too much will interfere with index of turret head. If the head does not index completely turn off motor, loosen the nut and tap turret head with mallet. This is a delicate setting, so proceed with very care. Continue adjusting and checking until the turret indexes smoothly without "Pounding".

M. RESETTING OF TURRET HEAD TO CORRECT "OVER" AND "UNDER" IDEXING This machine has been properly set at the factory and doweled in position so that the indexing mechanism carries turret to the next position without "over" or "under" travel from final index position. The mechanism indexes the turret head to an approximate position and a taper pin locates the turret head to a final accurate position. The geneva star wheel is fastened to the turret head with four cap screws.

1. Remove "FR" plate (part No.C-04-38) by removing three M4x12 cone head cap screws. 2. If turret head is over-indexing, correct by tightening (part No. C-04-5) turret stud nut 1/4 turn at a time until corrected. 3. If turret is under-indexing correct by loosening No.C-04-5 turret stud nut 1/4 turn at a time until corrected. 4.lanced condition exists in turret tooling there will be a slight over-index as the heaviest station is traveling downwards and a slight under-index as it is being carried upwards.

*VERY IMPORTANT: WHEN TURRET IS PROPERLY SET, IT WILL GAVE A VERY SLIGHT CLOCKWISE MOVEMENT AT THE END OF THE INDEX CYCLE, DUE TO THE LOCATTING PIN ACTION IN THE TAPERED BUSHING.

！WARNING: IF TURRET IS TOO TIGHT TURRET WILL FALL TO COMPLETE INDEX, CHECK ADJUSTMENT CAREFULLY.

N. SEQUENCE CHANGE OF TURRET SPINDLE SPEEDS

a. In order to disassemble or attempt a change of sequence of turret spindle speeds, it is necessary that you have available spindle and clutch puller, and oil seals No.C-04-24, because seals will be damaged in disassembly. b. DISASSEMBLY OF TURRET HEAD: Refer to part list drawing C-04 1.Remove "FR" plate No. C-04-38 and "O" ring No. C-04-37 on turret. 2.Remove lock nut No. C-04-5. 3.Remove spring washer No. C-04-4 and thrust bearing No. C-04-3. 4.Remove turret from slide body and remove oil seal No. C-04-35. 5.Remove oil seal No. C-04-24. 6.Remove truarc ring No. C-04-25. 7.With puller tap out spindle assembly. 8.Remove truarc ring No. C-14-11. 9.With puller tap out clutch assembly. 10.Press in new spindle assembly and replace truarc ring. 11.Tap in mating clutch making sure that gears mesh properly while pressing. 12.Replaces oil seal. 13.Remount turret, bearing, Spring washer and lock nut. 14.Reset turret head, per heading "TURRET HEAD"

O. UNIVERSAL DRIVE SHAFT : Refer to part list assembly drawing C- 02.The main universal drive shaft unit No.C-02-23 has grease sealed into each joint. Due to the extra capacity of the joints and sealed in lubrication, service should not be required. However, if it is ever necessary to replace the drive shaft, or universal joint connected with the drive shaft, move the slide body into uppermost position and shut off motor. Loosen set screw and pull universal yokes toward each other. This will disengage it from the shaft. To replace pulley side of universal joint, remove pulley, remove truarc ring No.C-02-13, pull out adjust eccentric wheel No.C-02-12 and press out shaft.

*WARNING: When replacing universal joints, it is very important that the locating flats on the universal joints are in line, otherwise, considerable noise and excessive wear will result.
