REGULATING THE MACHINE

7.1 - Cutting head
- If excessive axial play is found on the hinge, it will be sufficient to tighten the ring nuts ( A ), paying attention not to make the joint too tight.

7.2 - Vice

- The device does not require any particular adjustment; in the event of excessive play in the sliding guide, tighten the dowels ( B ) for adjusting the gib inside the slide. - Approach the vice jaw upto 4-5mm from the material to be cut.

CUTTING DIRECTION

The cropper is now ready to start work, bearing in mind that the CUTTING SPEED and the TYPE of DISC - combined with a suitable descent of the head - are of decisive importance for cutting quality and for machine performance (for further details on this topic, see below in the chapter on Material classification and choice of disks).
7.3 - Head return stroke limiting device
It consists in a mechanical adjustment system, mounted parallel to the head rise cylinder, to reduce the passive phases of the operating cycle, in other words to eliminate the idle stroke that takes place when the size of the part to be cut is much smaller than the maximum cutting capacity. Practically, you adjust the starting position of the disk in proximity of the part, independently of its dimensions.
7.4 - Restoring oil level in motorhead compensation cylinder tank
- Braking fluid in the cylinder controlling the head, may consume through the time. - It is therefore important to restore the oil quantity inside the compensation tank by removing the plug and then using a syringe type injector to fill the tank. - First, take the head to the upper position and disconnect airs upply from the pneumatic system (disconnect the air pipe from the machine). Switch on the machine and push the Line button. - Add oil making sure that the selector ( 5 ) is switched to the right (head downfeed). - Add oil until the rod, corresponding to the second mark on the stem, has come out completely. - Air must be bleeded from the tank by loosening the screw located on the side of the cylinder (see arrow) until some oil pours out (always keep the selector ( 5 ) to the right); when this has been done, secure the screw, remove the injector and put back the plug. - Connect the machine to the pneumatic system. - Use SHELL hydraulic oil 32 or similar.

7.5 - Piece-Counter

- Press Reset (A) and hold to release the Lever (B).
To carry out this operation you must: - slightly open regulator. - Rotate the selector ( 5 ) either to the right or left to lower or lift the motorhead. - position and secure the mechanical stop ( 8 ) against upper plate of the cylinder, so as to press the upper limit microswitch. - the lower limit switch ( 9 ) is set during inspection and limits the lower stroke of the motorhead. Do not change this setting. ATTENTION: - It is not necessary to adjust the upper end-stroke everytime; one can bring the disk near to the workpiece by means of selector ( 5 ) and then start the automatic cutting cycle wich will take place from the actual position of the disk. Do notice that, once the cut is completed, the motorhead will go to the upper end-stroke ( against the relevant microswitch ). - operate on regulator to modify motorhead return speed.

- Move the Lever (B) to the direction shown by the arrow and leave it in this position. Release the Reset button (A). Now the numbers appear on the window (C). - Hold the Lever (B) and set the number required by pressing the keys (D) starting from the left operating the two keys at the same time. - As soon as you set the first figure, you can go on towards the right with more figures. On the surface of each key there is a grooved area to set a single figure by means of a pencil. - Release the Lever (B) as soon as the setting is completed.

7.6 - Feed repeater

- You can set the number of feed repetition on the feed repeater just in case the cutting length required is longer than the mechanical stroke of the feeding system. Set 1 if no feed repetition is required. - Take into account the blade thickness and set the mechanical stroke of the feeding system accordingly. For example: In case you need 1500mm cutting length 1500 - 6 3
- Set the regulators A = forward I = backward to absorbe the mechanical stop of the feeding system during the cutting cycle.
1500 = cutting lenght. 6 = blade thichness ( 3 x 2 ) 3 = number of required feeding runs 498 = this is lenght the feeding stroke must be set to on the metric scale.
7.7 - Adjustment of pneumatic system pressure
- The pressure in the pneumatic system necessary for the proper operation of the sawing machine must be equal to 6 - 7 Bar. - Check on pressure switch (11) the exact correspondence and if necessary operate on regulator (12) to set the ideal pressure. - Make sure that a drop of oil runs through the lubricator bulb ( 13 ) every 4/5 work cycle.

7.9 - Decimal adjustment

- This is a fine cutting length adjustment by means of a Vernier (14). - Release the screw (15) and turn the vernier as much as you need with reference to the engraved marks. - One mark is 0.05mm (metric system). - One mark is 1/500 of a inch (English system) - Lock the screw (15).
7.8 - Adjustment of cutting length
- Proceed as follows to adjust the cutting length: - Loose screw ( A ). - Turn handwheel ( B ) to set the required cutting lentgh on the metric scale. - Lock screw ( A ).
7.10 - Adjusting the feeding system
- Adjust the feeding vices as follows: - Load the workpiece and clamp it in the bench vice by means of the relevant handwheel. - Loose the vice screw ( C ), approach the relevant jaw upto 45 mm from the material to be cut. Tight the screw. - Loose the vice screw ( D ), approach the relevant jaw upto 0,5 mm from the material to be cut. Tight the screw. NOTE: carefully adjust the vices ( C ) and ( D ). On the contrary, the microswitch controlling the presence of the workpiece will stop the machine. - Loose the bench vice allowing 4-5mm clearance from the vice jaw and the workpiece. BEFORE PERFORMING THE FOLLOWING OPERATIONS, THE ELECTRIC POWER SUPPLY AND THE POWER CABLE MUST BE COMPLETELY DISCONNECTED.

7.12 - Changing the disk

To change the disk: - Release the mobile yellow, white or orange guard and turn it back. - Block a piece of wood in the vice and lean the disk on it. - Insert the special spanner provided and remove the screw ( 1 ), slackening it in a clockwise direction because it has a left-handed thread, then slip off the flange that holds the disk. - Fit the new disk, checking the cutting direction of the teeth, then replace the flange, the screw and the mobile white, yellow or orange guard.

7.13 - Clutch adjustment

Inside the head there is a clutch device which has already been adjusted during assembly. If, after long use, further adjustment is necessary, proceed as follows: - remove the cover - fit the template provided - turn the motor shaft so that the ring nut ( 1 ) is in a convenient position to allow it to be tightened or slackened enough to calibrate the clutch system.
7.11 - Regulating arm blockage
- If there is insufficient blockage of the head arm in the desired position, slacken the screw ( 1 ) on the lever, hold the bush ( 2 ) in position, turn the lever to the left and tighten the screw.
ANY REPLACEMENTS OF OTHER PARTS - SUCH AS THE COMPONENTS OF THE REDUCTION GEAR, MOTOR AND VARIOUS ELECTRIC PARTS - MUST BE CARRIED OUT BY SKILLED OR COMPETENT PERSONNEL. 12
ROUTINE AND SPECIAL MAINTENANCE

8.4 - Six-monthly maintenance
- Change the oil in the reduction unit using oil type GEARCO 85W-140 by NATIONAL CHEMSERACH or MOBIL GLYCOLE 30 or KLUBER SINTHESO 460 EP or an equivalent oil, proceeding as follows:
- Remove the connecting plug from the electric box and unscrew the head moving lever. - Drain off the old oil from the cap ( 1 ). - Pour in new oil up to the mark ( 1 ), through the lever fixing hole, keeping the head in upper position ( 2 ). - Reassemble all the parts. - Check continuity of the equipotential protection circuit

MATERIAL CLASSIFICATION AND CHOICE OF TOOL
8.5 - Oils for lubricating coolant
Considering the vast range of products on the market, the user can choose the one most suited to his own requirements, using as reference the type SHELL LUTEM OIL ECO. THE MINIMUM PERCENTAGE OF OIL DILUTED IN WATER IS 8 - 10 %.

8.6 - Oil disposal

The disposal of these products is controlled by strict regulations. Please see the Chapter on Machine dimensions - Transport - Installation in the section on Dismantling.
8.7 - Special maintenance
Special maintenance operations must be carried out by skilled personnel. However, we advise contacting THOMAS or their dealer and/or importer. The term special maintenance also covers the resetting of protection and safety equipment and devices.
Since the aim is to obtain excellent cutting quality, the various parameters such as hardness of the material, shape and thickness, transverse cutting section of the part to be cut, choice of the type of cutting disk, cutting speed and control of head descent, must be suitably combined.These specifications must therefore be harmoniously combined in a single operating condition according to practical considerations and common sense, so as to achieve an optimum condition that does not require countless operations to prepare the machine when there are many variations in the job to be performed.The various problems that crop up from time to time will be solved more easily if the operator has a good knoledge of these specifications. WE THEREFORE ADVISE YOU ALWAYS TO CHOOSE ORIGINAL SPARE DISKS THAT GUARANTEE SUPERIOR QUALITY AND PERFORMANCE.
9.1 - Definition of materials

9.2 - Choosing the disk

First of all the pitch of the teeth must be chosen, suitable for thematerial to be cut, according to these criteria: - parts with a thin and/or variable section such as profiles, pipes and plate, need close toothing, so that the number of teeth used simultaneously in cutting is from 3 to 6; - parts with large transverse sections and solid sections need widely spaced toothing to allow for the greater volume of the shavings and better tooth penetration; - parts made of soft material or plastic (light alloys, mild bronze, teflon, wood, etc.) also require widely spaced toothing.

9.7 - Type of disks

The disks differ essentially in their constructive characteristics, such as: - Tooth shape - Tooth cutting angle Tooth shape The profile of the toothing depends on the size, shape and thickness of the section to be cut, either straight or at an angle. It may also vary according to the pitch, but not so distinctly as to make this an element for classification. - Fine toothing is to be chosen for cutting small sections with a profiled shape and tubular sections with thin walls (2-5 mm depending on the material). - Large toothing is suitable for cutting medium and large solid sections or fairly thick profiled or tubular sections (over 5 mm). "A" toothing: normal fine toothing "AW" toothing: fine toothing with alternate side rake

9.3 - Teeth pitch

As already stated, this depends on the following factors: - hardness of the material - dimensions of the section - thickness of the wall.

S (MM) up to 2

PICTH 4-13
SHAPE B shaped C solid C solid C solid C solid C solid C solid

SPEED 3 3-1 1

C (HZ) toothing: large toothing with roughing tooth with rake on both sides, alternating with a finishing tooth without rake. The roughing tooth is 0.15-0.30 mm higher Added toothing: disks made in this way are used for cutting non-ferrous metals, such as light alloys, and plastics, and above all in wood-working. The teeth are hard metal (HM) plates brazed onto the body of the disk; there are various types and shapes and, considering the vastness of the field, the topic is not developed further here. "B" toothing: "BW" toothing: normal large toothing with or large toothing with alternate without shaving breaking inci- side rake sion

10 over 10 up to 20

9.4 - Cutting and advance speed
The cutting speed (m/min) and the advance speed (cm2/min = area travelled by the disk teeth when removing shavings) are limited by the development of heat close to the tips of the teeth. - The cutting speed is subordinate to the resistance of the material (R = N/mm2), to its hardness (HRC) and to the dimensions of the widest section. - Too high an advance speed (= disk descent) tends to cause the disk to deviate from the ideal cutting path, producing non rectilinear cuts on both the vertical and the horizontal plane.
Tooth cutting angle Each tooth has two cutting angles: - : front rake angle - : rear rake angle SHARPENING CIRCULAR SAWS
9.5 - Running in the disk
When cutting for the first time, it is good practice to run in the tool making a series of cuts at a low advance speed (= 30-35 cm2/min on material of average dimensions with respect to the cutting capacity and solid section of normal steel with R = 410-510 N/mm2), generously spraying the cutting area with lubricating coolant.

T p d 3 1,2,3,4,8

9.6 - Disk structure
The most commonly used disks are made of extra high speed steel (HHS) of normal quality (HHS/DMo5) or superior quality (HHS/Mo5 + Co5) with a treated tooth, which differentiates them from the former on account of the high value of structural resistance, greater resistance to seizing, absence of stress in the mass and a better holding of lubricating coolant during work.
