Page 16: Instructions For Use
5. INSTRUCTIONS FOR USE 5.1. Bending principles The bending of the different profiles and tubes is carried out by passing the material through the three driven rollers located at the front of the machine. Out of these 3 rollers, there is one fixed, and the remaining two are moveable. - Page 17 SECTION BENDING MACHINE MC650 5.3. User guide A control panel with a multi-function touchscreen is used to operate the MC650 hydraulic pipe bender. The machine can also be controlled with a movement button and a four-way joystick for easier roller positioning.

Page 18: Instruction Manual
This is largely the man/machine interface. However, reading the steps indicated in the following sections is recommended in order to be able to work with the machine safely and comfortably. 5.3.1. Manual operating mode After turning on the power to the machine (“Power On”), the manual mode graphic interface is displayed on screen. - Page 19 SECTION BENDING MACHINE MC650 The bottom of the screen is reserved for the active mode horizontal menu buttons. In view of the message that appears at the top, the system must be reset in order to work appropriately. To do so, press the button on the horizontal menu.
-
Page 20: Automatic Operating Mode
Besides the hydraulic movement of rollers X and Y which can change the pyramid-like triangle geometry of the machine for different bending radiuses, the MC650 allows synchronized rotation of the three pull rollers for optimal bending on the pieces to be produced. -
Page 21: General Data
SECTION BENDING MACHINE MC650 Automatic operating mode allows you to create and save bending programs for mass production with the possibility of multiple radiuses on each piece. This operating mode is an evolution over the manual opera- ting mode and, as seen below, it is also simple and powerful. - Page 22 Now, you just need to complete the information by pressing on each of the items that appear on screen. They are: 1.- The type of profile (top). 2.- Dimensions and material (middle). 3.- Rollers used and their position on each axis (bottom). 4.- Custom roller (data only visible for custom profiles).
- Page 23 SECTION BENDING MACHINE MC650 Upon pressing the material icon, you’ll see a list from which you can choose the material. Choosing the rollers is just as intuitive. The following graphic will appear upon selecting the top or bottom axis. - 22 -...
-
Page 24: Using The Programs
Using this interface, you can flip each one of the rollers (by pressing the arrow above them) and place them on the axis (by pressing the desired roller). Keep in mind that the order in which you press each one of the rollers will be the order in which they will be inserted on the axis. - Page 25 SECTION BENDING MACHINE MC650 You can save your program with these basic steps but you’ll need to create a new program at some point or load a previously created program. This function can be found by pressing the icon in the horizon- tal menu giving you access to the program management screen.

Page 26: Creating A New Program
5.3.4. Creating a New Program All of the programs created are made up of steps. A program can have as many steps as are necessary to generate the geometric shape required based on the piece curving. The first step of a program is known as the “loading step” which is when the position of the bending rollers allows the entrance of the material the machine will work with. - Page 27 You must be aware that any program created with our MC650 bending machine absolutely requires these two steps before bending can begin. The reason is to provide you, as the user, with a comfortable and safe operating mode all while guaranteeing the result obtained for all pieces of the same type of profile or pipe will be excellent for exceptional repeatability throughout the entire series.
- Page 28 Now, with the material secured in the machine, it can be placed in position to begin bending by making the rollers rotate towards the left or right as learned in the section on the manual operating mode. Once the profile or pipe to be processed is in the required position, choose which of the two rollers (X or Y) you want to move to begin making the desired bend.
-
Page 29: Production Mode
SECTION BENDING MACHINE MC650 Remember that a program does not have to create just one bend radius in the piece to be processed. You are the one who decides how many you want to create. And this gives rise to end pieces of varying geome- tric complexity. - Page 30 Therefore, if you wish to make last minute corrections before mass producing pieces when already in pro- duction, you can return to the program editing mode by either pressing the icon on the vertical menu or pressing the automatic mode icon Either way, you will then be able to edit the currently loaded finished program.
- Page 31 SECTION BENDING MACHINE MC650 Use the numerical keyboard to make the adjustment to the height of the chosen axis. To confirm, press the “SET” key. As soon as you finish making the adjustments or corrections in the different steps (if necessary to finish refining the resulting piece), you can return to production mode and begin the series.
-
Page 32: Using Materials And Tools
Now go to step 3 of the program. Push the movement button and the axis for which the height is defined will move into position, creating the beginning of the bend for the piece. Make the bend by getting the ro- llers to rotate left or right, as necessary. - Page 33 SECTION BENDING MACHINE MC650 By using the horizontal menu here on this screen, you can do the following: Create a new material Edit materials Delete materials Switch to the tool management screen (custom rollers) For clarification purposes, remember that each one of the materials is defined by a descriptive name plus a coefficient representing its physical resistance.
- Page 34 This is the custom roller management screen: Just like with the material management screen, the following actions are possible if you press the icons in the horizontal menu: Create a new custom roller Edit an already-existing custom roller Delete a custom roller Switch to the material management screen Remember that each custom roller is defined here with a descriptive name plus an effective diameter.

Page 35: Importing And Exporting Data
SECTION BENDING MACHINE MC650 5.3.7. Importing and Exporting Data The same software that runs on the physical machine can be run on a PC with a Windows operating sys- tem. This makes it possible to get the operators and technicians who will intervene in the development and production process familiar with the environment they will later use. -
Page 36: Using The Alarms
All of these data are imported and/or exported using a USB memory stick which can be inserted into the corresponding connector on the control panel. It is also of vital importance to emphasize at this point that you can export and/or import data to the system’s internal memory. This allows you to have a backup copy on the machine itself which can be recovered whenever necessary. - Page 37 SECTION BENDING MACHINE MC650 The question now is how to tell if the system has an activated alarm. You just look to see if the icon appears at the right of the message bar at the top of the screen.
