START UP
Once the machine is located in your workplace, you must remove the protections placed for transport as well as the anti-corrosion protective grease.
If refrigeration equipment is included, it must be filled with water + coolant in the appropriate proportion according to the manufacturer of the coolant and the hardness of the water. The water used must be potable water with a recommended hardness between 10º to 20º.
For the electrical connection you must contact a qualified technical installer according to the current regulations of the country.
CHECK THE DIRECTION OF ROTATION OF THE MOTOR
To check the correct connection of the electrical phases, start the motor of the cooling pump and observe the direction of rotation of the shaft, it must coincide with the direction of rotation marked on the pump. If they do not coincide, reverse two of the phases in the machine connection input or in the electrical outlet of your installation.
INSTRUCTIONS FOR OPERATING THE MACHINE
FIRST COMMISSIONING
Turn on the machine by placing the ignition switch lever in the ON position. Releases the emergency stop if it is activated.
The LCD screen will turn on displaying a check message. Once the check is finished, the axis referencing message will be displayed.
IMPORTANT: You must check that no axis will collide with a tool or person.
Before referencing, you are allowed to move the axes with the movement buttons, to release, for example, the possible collision with a tool already mounted.
The order of referencing the axes is as follows: Z, Y, X. When you finish referencing an axis, it stays in its position and starts referencing the next axis.
CONTROL OPERATION
The arrow keys: Up, Down, Depth, Height and Rotation, are used to move the corresponding axes (depending on the automated axes of the machine you have purchased). The regulation of the speed of the movement is carried out by means of the axis speed selector. NOTE: You must first adjust the speed with the selector, and then move the shaft. The speed selection while the axis is already in motion will be ignored.
Turning the light and cooling on and off is done manually using the button designated for that function.
The START and STOP buttons are used to confirm / cancel automatic movements.
IMPORTANT: The STOP button is not an emergency stop: When the STOP button is activated the machine will stop the automatic work cycle when it is in a safe position (for example when it has moved away from the cutting tool edge) to avoid collisions.
If the machine is needed immediately, the EMERGENCY STOP button must be used.
The menu selector allows you to navigate through the menu that appears on the LCD screen, as well as to edit the program values.
After homing, you can move the machine with the axis direction buttons.
IMPORTANT: Before referencing, the machine does not know its current position, so operating the axis movement buttons could cause a collision due to excess travel of the driven axis.
To run a sharpening program, select one of the programs from the menu. You can store up to 20 programs (from No. 1 to 20). The editable options can be seen below:
- Roughing: Amount to sharpen. The first value corresponds to the total amount. The second is the partial amount of sharpening to apply for each pass of the wheel. The V value corresponds to the working speed, so that 100% corresponds to 100% of the value selected in the axis speed selector. For example, a value of 50% will correspond to 50% of the value selected in the axis speed selector.
- Lapping: These are the passes that will be carried out without applying load (polishing or finishing passes). The% V value corresponds to the value selected in the axis speed selector.
- Nr. Of teeth: The total of teeth that the tool has. The machine will carry out an exact division according to the number of teeth, so that if 4 teeth are indicated it will carry out divisions of 0º, 90º, 180º and 270º.
- Tooth orientation: position of the tooth depending on the tooth. Front: Tooth facing towards the grinding wheel. Rear: Tooth looking against the grinding wheel.
- Operating mode: Tooth per cycle: It carries out all the passes on the current tooth and once it is finished it continues with the next tooth. Cycle pass: Performs one pass on the current tooth, then proceeds to the next tooth: Useful when the number of teeth is so large that the wear on the grinding wheel between the first and last tooth is significant.
- Head position: Place where the dividing head is located: Left or right, depending on the point of view of the machine operator.
- Direction of rotation of the dividing head: Direction of rotation of advance of the dividing head when it passes to the next tooth.
On the next screen you can set the direction of rotation of the grinding wheel as well as the speed of rotation.
IMPORTANT: Never rotate the grinding wheel faster than the manufacturer's recommended speed. It could cause breakage, wheel loosening as well as damage to operators and personnel.
Once the program is created, click on the SAVE button. Now you can transmit the program to the control using the START button. You will be warned that the grinding wheel will begin to rotate.
IMPORTANT: You must ensure that neither you nor any dangerous part is in contact with the grinding wheel.
If you press the START button now, the grinding wheel will start to rotate. Now you must place the grinding wheel in contact with the piece to be sharpened. Once the grinding wheel is rubbing against the piece to be sharpened and you have verified that the sharpening path is correct (do not hit any part of the machine or tool), you can press the START button again to start the automatic work program.
IMPORTANT: Using the axis speed selector, you can adjust the speed of movement of the axes to position the tool.
IMPORTANT: Once the machine is running the automatic sharpening program, you can adjust the sharpening speed using the axes speed selector. The selected speed will take effect once the movement has reached an extreme, never in the middle of the movement.
STOP button
IMPORTANT: The STOP button will never stop the machine suddenly, to stop the machine quickly you must press the emergency button. The STOP button will give the instruction to stop the sharpening program and the machine will stop once the sharpening movement has finished and is at the beginning of the sharpening pass, to stop safely and without making marks on the sharpened piece .
MAINTENANCE
To clean the machine, never use compressed air: it will embed the dirt inside the guides and bearings. To do this, clean dirty surfaces on a regular basis, and operate the machine's greaser at least once a week.
Remove the coolant if the machine is not going to be used for more than 1 week to avoid the growth of bacteria.
In the case of anticipating prolonged stops, you must protect the surfaces that are not painted (guides, table, column, etc.) with an anti-corrosion agent. This anti-corrosion agent must be removed before restarting the machine.
In the case of damaged parts, we recommend that you always use original parts. We are not responsible for failures caused directly or indirectly by the use of parts that are not suitable or intended for the use of the machine.
ACCESSORIES
You can obtain a list of recommended original accessories by contacting us directly or through your official distributor.
