EF-AC/80
CHAMFER MACHINE

SAFETY PRECAUTIONS
● Before turning on the power switch, make sure you fully understand the content in the Manual, and
make sure no personnel or obstructions in the hazardous area and work space
● After unpacking the machine when first operation or after a period of inactivity, the sliding mandrel need
to be put oil on it.
● Please memorize the position of emergency stop switch to ensure that when an emergency situation
occurs, the operator or other personnel to press the switch immediately, in order to avoid danger.
●The machining tool must meet the tool specifications or contact our sales department
●When replace the blade, please turn off the main power to ensure safety.
● Keep proper clamping when chamfering to avoid parts loose that make harm on the blade, the
machine or personal.
●Turn off the main power supply and clean environment around the machine and do the daily
maintenance of machinery when staff complete work and leave machine.
●Do not take off safety shield to avoid metal shavings flying to hurt people.
●Before starting machine or after shutdown machine, must add oil on it and keep it clean.

MACHINE
1.Manually put raw material to machine for EF-AC / 80 type which clamp
materials, feed, retraction automatically, processing speed, good
accuracy, can trim the end face of the workpiece. The inner and outer
chamfering are completed in a chamfering process
2.The workpiece clamping mould and knife block are precision
engineered to ensure the perfect quality of its processing.
3.This machine is assembled with standard baldes so that it is simpler
and faster to replace blades.
4.Upon receipt of the product, please check the following accessories
are ready：
（1）EF-AC / 80 a chamfering machine
（2）an adujstable blade knife
（3）three clamping material moulds
（4）wrenches

APPLCATION INSTRUCTION
1.Preparation of Application
(1) This machine uses a three-phase power supply,and make sure the machine power
supply to match the voltage.
(2) This machine uses compressed air pressure which is greater than 1HP.
(3) check the machine structure is no problem, and all tools are all ready.
2.Installation of a machine
（1）Turn on the power
（2）Connecting air hose to the machine air interface.
（3)Confirmed the steering of motor is on right direction- Note: Steering error will
damage the machine and the blade
（4）Replace different blades depending on the form of chamfering

APPLCATION INSTRUCTION
3.Steps of machine adjustment
（1）Turn on the power
（2) Check the pressure gauge shows the index (Figure 1), rotary pressure adjustment switch, so
that the working pressure reach to 6-8 kilograms per square centimeter

APPLCATION INSTRUCTION
（3）Loosen properly fixing screws of outer blades holder and inner blade holder (Figure2 ),
adjust outer blade holder inward and outward,and adjust inner blade holder inward so that
correct the end cutter holder

APPLCATION INSTRUCTION
（4）Switch to automatic mode (Fig 3)

APPLCATION INSTRUCTION
(5) rotary hydraulic control valve (Fig. 4), adjust the appropriate feed rate (the bigger the
number, the faster)

APPLCATION INSTRUCTION
(6)) Put material into a mold, step on the pedal switch to test machine, adjust feed cylinder,
and the end of positioning plate (FIG ⑤) and the front limit photoelectric switches, back limit
photoelectric switch, so that the end face of blade holder cut the material end face at an
appropriate rate, and ensure that at the appropriate opportunity to reduce speed to feed and
retract.

APPLCATION INSTRUCTION
(7) Adjust the position of inner blade holder and outer blade holder, locking blade holder
and fixing screws and then test machine.
(8) Repeat (7), until achieve satisfying chamfer angle

REGULAR MAINTENANCE
Daily maintenance:
1.Fill oil on shaft every day before open machine. Method: Gently press trolley of hand pump lever at 2
or 3 times
2.Clean up metal shavings on machine after working.
3. Wipe the machine. keep it clean, and also add oil on it.
Accessories complement and update
1. The combination of three complementary lubricating oil (SAE10 # oil)
Inspect oil of empty oil conversion cylinder (SAE10 # oil,can work normally with 60% oil) hydraulic
system is a closed system. Circulating oil is generally not consumed. If not normally reduction , please
check whether the seals and tubing damage. On normal condition , circulating oil need to be change
new every six months.

Precautions:
1.The power cable connection way is related with the direction of steering motor , and do not change
it without specially instruction.
2.Confirming the voltage is normal
3. Make sure the fuse meets the specification
4. The blade is replaceable blade, and replacing depend on different workpiece materials.
5.Blade Specifications

TROUBLE REMOVAL
1.chamfering uneven
（1）Maybe Moulds do not match spindle well. You can loose four screws on fixing mould and
change to manual mode. Put material into it and fix it. And then fasten four screws.
（2） Raw material facing end vertical not well
（3） Size of mould is too big and can not fix well when chamfering
（4） Blade material is not suitable for cutting the workpiece
2.The end faces appear wavy lines
Feed rate is too fast.The machine feed include fast feed at first step and cutting at the second step.
The position of the moderative block depends on the feed speed , and put the block at the righter
position the cutting processing is sooner.During fast feed process and retraction process the spindle
are the fastest feed speed. And during cutting stroke,feed rate was controlled by the control valve,
data is bigger the speed is faster.

TROUBLE REMOVAL
3.The feed speed is unstable
（1）Check the pressure of the compressor is enough or not
（2）To check the pressure gauge of machine is sufficient or not
（3）Check the oil in the oil converter is adequacy or not
（4）Check the degree of lubrication of all sliding mandrels is adequate or not
4.The workpiece is clamped lossen ,and are pushed out when the feed:
（1）The speed of feed is too fast when cutting and chamfering,and the friction coefficient of
different materials is not same. So can not produce the mould suitable for all materials.So the
correct approach is to slow the speed of feed and despinning.
(2) The force of friction is reduced on workpiece and mould surface. And please keep those surface
dry.
