19. LOWER ROLLER UNDERTABLE ADJUSTMENT
a)
The motor-powered lower roller must be vertically adjusted so that it protrudes by 0.05 mm max. with respect to
the table.
b)
Vertical adjustment should be carried out by using the two screws located at the lower ends of the roller itself;
lock by tightening the nuts.
20. FEEDING DEVICE ADJUSTMENT
Feeding roller vertical position adjustment
To adjust the vertical position of the feeding unit, proceed as follows:
-
Position the unit at a reference height from the table (for example, 30 mm), reading the height on the index on
the plate located at the infeed section.
-
Adjust the steel rollers so that the lower part of the diameter is 27 mm in height with respect to the table
-
Adjust the rubber rollers so that the lower part of the diameter is 25 mm in height with respect to the table
Feeding unit vertical adjustment
To position the feeding unit based on the thickness of the finished workpiece, use the upstroke and downstroke
switches and check the level on the index on the plate located at the infeed section.
Air pressure adjustment
Pressure adjustment in the steel and rubber roller is carried out separately by acting on the filter-air regulator unit
handwheel and reading the value on the pressure gauge (normally set at 0.3 Mpa).
21. CLEANING AND LUBRICATING.
Frequent maintenance ensures your machine will last longer and always provide optimal performances.
Plus, also overall cleaning of the machine and of the surrounding floor will improve overall safety.
Frequent cleaning:
Clean the machine using a solvent and compressed air to avoid the formation of scales, particularly on the table,
slideways, shafts and cavities, wherever residues of dust and chips are visible.
When using compressed air, avoid pointing the jet towards fences and supports, to prevent chips from
accumulating in the tool support and in the spindle bearings.
When cleaning and lubricating, make sure not to apply grease to belts or drive pulleys, as this might compromise
machine operation.
If required, clean belts with a cloth or a rag and use kerosene or turpentine for the pulleys.
Avoid all contact between belts and solvents or lubricants.
Besides the above mentioned items, clean or lubricate all moving parts, rods, threaded bars, pins and any other part
which may be prone to oxidizing.
Lubrication:
Prior to any repair and maintenance operation, disconnect the electrical and pneumatic mains power supply.
Lubricate at a temperature higher than 120ºC and use lubricant ZG-3 ,ZG-0, gear oil 90#, motor oil N46.
Roller gearbox:
check oil level through the indicator. Oil should be added or replaced when below the required level or when level is
not visible.
a)
Slacken the drain cap and let all impurities flow out from then bottom, then close.
b)
Pour oil through the filter until the level is up to the line marked on the indicator.
