1. Early in place and connect the main machine.
Users should be in the machine before the arrival of the machine tool manufacturers to provide basic tools to do basic map,glue stick the site of the installation bolt holes do reserved. When the CNC machine tools shipped to the user, according to procedures to machine parts out of the box shipped to the installation site. Then, according to the instructions described in the composition of the major machine components are in place in the foundation. In place, the horn,glue gun adjust the pads and anchor bolts and other appropriate condemnation.
Machine tool parts and then assembled into machine parts after the completion of the cable assembly, tubing and pipe connections. Machine instructions have electrical wiring diagram gas, hydraulic piping diagram, shall be construed accordingly to the cables and pipes connected by marking eleven checkmark.
Note at this stage are as follows:
1) After unpacking the machine were the first to find the documentation, find the machine packing list, packing list and check the box under the spare parts, cables and materials are complete.
2) The machine parts before assembly, first remove the connector surface, rail and surface rust paint the movements, the parts look good cleaning.
3) connection with particular attention to the work and reliable access to clean and seal, and check for loose and damaged. After the cable plug must be screwed tightly fixed screw, to ensure reliable contact. Tubing, pipe connection, particular importance to prevent foreign matter from the interface into the pipe, causing the entire hydraulic system failure, each connector pipe connection to be tightened. After connecting the cable and tubing, to ensure that the pipeline in place fixed, the installation of protective casing to ensure a neat appearance.
2. Numerical control system access and debugging.
(1) check out of the box CNC systems.
Purchased either individually or with the machine tool numerical control system supporting the purchase of CNC machine, after the arrival out of the box should be carefully checked. Check the body, including the system and its accompanying feed speed control unit and servo motors, spindle and spindle motor control unit.
(2) external cable connections.
Is the index of the external cable connection control device with external MDI / CRT unit, high power cabinets, machine operator panel, feed servo motor power lines and feedback lines, power lines and the spindle motor feedback signal line connections and with the manual pulse generator connection. Should make these consistent with the supplied connection manual. Finally, it should be ground connection.
(3) CNC system power cord.
CNC cabinet should be cut off the power switch in the case of CNC cabinet connect the input power transformer primary side cables.
(4) Set the confirmation.
Printed circuit board within the NC system, there are many with a short jumper set-point, it needs to the appropriate machine settings to suit the different requirements of various models.
(5) Input power supply voltage, frequency and phase sequence confirmation.
NC has a variety of DC power within the system, the system provides the required +5 V, ± 5V, +24 V and other DC voltage. Therefore, the system power, should check whether the load of these power-to-ground short circuit. Multimeter can be used to confirm.
(6) to confirm DC power supply unit output voltage is short-circuited.
(7) connected to numerical control cabinet power supply, check the output voltage.
Before the power, in order to ensure security, you can simply disconnect the electrical power lines.
Turning on the power, first check whether the NC cabinet fans all spin, you can make sure the power is switched on.
(8) to confirm the parameters of CNC system settings.
(9) confirmed that the machine tool numerical control system side interface.
Complete these steps, you can adjust that NC system has been completed, with the power-line test with the machine's condition. At this point, CNC system and cut off the power, connect the motor power lines and restore the alarm settings.
3. Power test machine.
Required by the instructions to the machine tool lubrication, oil lubrication points and oil infusion requirements, cleaning the fuel tank and hydraulic filters, hydraulic oil poured into the label provided. Hydraulic oil prior to being filtered. Gas source connected to the external input.
Machine power operations can be a different part of the overall power supply, or supply the parts separately, and then for the total supply test. Were relatively safe power supply, but a long time. First, observe whether the alarm after power failure, and then manually start the various components in succession. Check whether the role of safety devices, can work, can achieve the rated performance indicators. The total child, a rough check of the machine tool specification data major components, function is normal, complete, so that the machine can operate all aspects of moving.
Then, adjust the level of the machine bed, the main coarse geometric precision machine tools, and then adjust the main moving parts of reassembling the relative position of the host, with quick-drying cement perfusion host and anchor of the attachment, the level of each reserve hole , and other cement completely dry.
CNC machine tools in line with the power test, though the NC system has been confirmed working without any warning, should be power at the same time, press the emergency stop button well prepared, ready to cut off the power.
At checking the functioning of each axis machine, the application of manual continuous feed movement of the shaft, through the CRT or DPL (digital display) display the value of checking the correct direction of movement of machine components. Then check whether the distance of the axis movement command line. If no, should check the relevant instructions, feedback parameters, and position control loop gain and other parameters set correctly.
Then, and then manually move the axes into the give low and that they come across super-way switch, overtravel limit to check the validity of numerical control system is an alarm in the ultra-Cheng.
Finally, the reference point should be a return to action. After the machine tool reference point is the procedure for processing the reference position, therefore, must check whether the reference point return to baseline function and location of each is exactly the same.
4. Debugging machine accuracy and features.
The foundation has been solidified in the use of anchor bolts and horn on the fine-tuning the level of machine tool spindle bed, moving bed, after the level of alignment of all moving parts of the body (the main column, slide plates and tables, etc.), to observe the coordinates of the whole itinerary the level of transformation tools, and to adjust the geometric accuracy of machine tools to make the allowable error range. Detection tools using precision level meter, standard cubic feet, flat feet, parallel to the light pipe. In the adjustment, mainly to adjust the horn-based, if necessary, slightly changing the inserts on the rail section and the tightening wheel and so on.
Machine tool to automatically move to the exchange of location (available G28Y0Z0 or G30Y0Z0 such procedures), adjusted manually loading and unloading knife blade robot manipulator position relative to the spindle. In the heart of the adjustment rods using a proofreading test, there is error of adjustable travel manipulator, mobile robot bearing and tool location, tool change position if necessary, can modify the set point (numerical control system to change the parameter settings .) After adjusting the adjustment screw and tighten the bolt magazine, and then loaded on a few provisions to allow the weight of the handle close to, several from the library to the main axis of the reciprocating tool automatic exchange, requiring action is accurate, no impact, not out knives.
APC pallet machine with table movement to make the exchange position, adjust the pallet station and the exchange of the relative position of the table, to ATC when the table is smooth, reliable and correct. And then loaded on a countertop 70 to 80% of the permitted load, several automatic exchange movements, to correct and then fastening the relevant screws.
Double-check system and PLC devices in the NC parameter setting information in compliance with the provisions of random data, and then test all the major operating functions, safety measures, such as the implementation of commonly used commands. For example, various operation modes (manual, to move, MDI, automatic, etc.), the spindle hanging file command, at all levels of instruction and whether the correct speed.
Adjustment process in the machine tool, general machinery related to modification and NC parameters, such as the origin location of each axis and the machine components to modify the parameters related to location, like a knife blade box coordinates location library. The revised parameters should be recorded in the acceptance or stored in a medium.
Check the accessibility and accessories to work, such as machine tool lighting, cooling boxes of various guard shield is complete; to fill the coolant tank coolant, test whether the normal spray nozzle cutting fluid; in the use of cooling shield leakage under the conditions of whether the cutting fluid; conveyor can work properly; spindle head and the thermostat tank whether it works and so on.
5. Test run.
After installation of CNC machine tools, requiring machine in with a certain load conditions automatically after a longer period of time to check the machine run more comprehensive functions and working reliability. Running time there is no uniform requirement, generally run daily 8h, continuous operation of 2 to 3 days; or 24h continuous operation of 1 to 2 days. This process is called the test run after installation.
Assessment procedures shall include: the main function of the system to use CNC, automatic replacement of two-thirds of the library to take a knife tool, the spindle of the highest, lowest and common speed, fast, and commonly used feed rate, the table of the automatic exchange The main use of M instructions. Machine Tool run-time test should be studded hilt, provides access to handle the weight should be close to the weight of the counter exchange of responsibility should also be added. In the test run time, in addition to other failures caused by operator error, faulty machines are not allowed there, or that the machine installation and commissioning problems.
6. Acceptance testing of CNC machine tools.
Acceptance of CNC machine tools can be divided into two categories: one is the prototype for the acceptance of new CNC machine tools, machine tools designated by the State Inspection Center; CNC machine tools and general user acceptance of its acquisition of CNC equipment.
Prototype for the acceptance of new CNC machine tools, the need for comprehensive test. It requires the use of high precision equipment to the machine's mechanical, electrical, hydraulic, gas and other machine parts and a comprehensive performance and individual performance testing, including stiffness and thermal deformation of machine tool and a series of experiments came to the conclusion of Comprehensive Evaluation of the machine.
CNC machine tools for general users, primarily on the basis of its acceptance test certificate on the machine tool factory acceptance conditions and the actual provisions of the detection means to provide part or all of the certificate on the machine to determine the technical indicators. Qualified for future maintenance will be the technical indicators are based. Main tasks are as follows:
(1) visual inspection machine.
CNC machine tools in the detailed inspection and acceptance prior to the appearance of the cabinet should also be checked CNC inspection should include the following aspects:
1) Check the appearance of NC by visual inspection of each unit in the cabinet for damage, contamination, bundled cable for damage, if the shield spalling.
2) CNC cabinet parts, including screws fastening fastening checks checks checks fastening the connector, tighten the inspection of printed circuit board.
