CNC Plate drilling machine fault analysis

Supertime Technology.

When use the CNC Plate drilling machine to return the reference point, the coordinate axis without reaction. How to check the machine ?  Check the fault one by one as follow:

1.Safety of mechanical components

1. Check whether the components are in a safe position, the pressure in the upper position, the hydraulic system is open, the normal safety switch.

2. Whether each axis is outside the range limit.

2. Coordinate servo parameter setting

1. Check the coordinate parameters of the reference return mode.  

2. Check the coordinate parameters of the reference point shift and fast positioning speed.  

3. Servo driver failed to get signal

1. check output port

2. check circuit

3. check drive module

4.Servo driver no power

1. check circuit

2. check power module

3. check drive module

4. check servo power supply air switch 

5. Coordinate axis control cable breaker

The Coordinate axis control cable between the CNC control device and servo driver not connect enough or breaker.

CNC High speed angle drilling machine performance

Supertime Engineer Department.

With the development of smart grid and UHV power transmission, tower manufacturing level is also greatly improved. In the design of the tower section angle steel and high strength steel angle is used more and more widely, according to the requirements of the standard of GB2694-2010, thickness greater than 8-20mm (angle and material), the angle, the original NC hydraulic angle punching production line processing technology, we must use the drilling process to complete, such CNC angle drilling and production line is more and more widely.

Jinan Supertime Technology Co., Ltd. in 2007 launched a JX2532 CNC angle drilling production line, launched in 2009 JX2532F CNC angle high speed drilling production line, launched in 2012 JX3540D CNC angle high speed drilling production, 2014 launch JX3635F numerical control angle steel high speed drilling production line, has been widely used in the market.

Production efficiency and cost:

From the current market actual use situation analysis comparison, same cutting 20mm thick steel, common drilling net drilling time about in 30 seconds or so, a high-speed drill net drilling time in 10 seconds or so, simple from the drilling time see high-speed drill is about 2.5-3 times that of ordinary drilling. That is to say, it has a great advantage to compare the high speed drill from the production efficiency.

The actual use of cost: ordinary drill taper shank twist drills, for a bit to drill many holes, now there is no market is clearly a statistical data, by consulting the user probably derived the following conclusions, a relatively good quality of twist drill, the drill worn ideal state, about to 4000 holes. According to a drill bit 40 RMB to calculate the average cost of a hole tool loss of about 0.01 RMB / hole. For high speed drilling, a pair of blades can be drilled on average 800 holes, but the blade is four faces can be used, is the 3200 hole, a pair of blade price is about 140, equivalent to 0.04375 RMB / hole. In this way, the processing cost of a single hole is more than 4 times as high as that of a common drill.

Above refers to the use of the ideal state, for the common drill bit edge grinding will affect the life of the drill bit, which is a variable factor. For high speed drilling, and the service life of the blade is fixed, but must be replaced ahead of the blade, can't it wear the change again, so it is easy to make blade and a fixed blade bit sintering together, the drill completely scrapped, and a drill handle cost at least 2500 RMB will greatly increase high speed drilling cost.

Of course, considering, comprehensive cost efficiency in the use of a device can not only a few points from the above analysis, relatively high-speed drilling in the area, the operator number of than the same workload of ordinary drill to save one third of.

Automatic operation of CNC angle line

Supertime engineer department.

CNC Angle line is a with the three NC axes of the automatic production line, FOR angle punching,marking, cutting and other machining operations.  The following introduces relevant content of automatic operation under Jinan Supertime  CNC angle line equipment.

1. Automatic operation

Under the automatic operation mode, the user first writes the work piece program, then writes the nesting procedure. In the end, the discharge program will be transmitted to PLC, and the system will automatically press the program to execute the nesting process step by step, so as to finish the mass production of the workpiece. The following is a detailed description of these processes.

2.Workpiece programming

Workpiece programming is to press the workpiece drawings, prepared into a computer can accept the program. A workpiece program defines a work piece. In a workpiece program, the user needs to be specified in accordance with the provisions of the length of the workpiece, the specification, the hole and the distance between the end of the distance and the typing position, etc..

3. Workpiece program management

The workpiece program is stored in the database, in the program list, you can create new programs, edit, delete, copy, rename, graphics preview, clear the finished workpiece, nesting, open the list of scheduling operations.

4. New workpiece program

In the work program list window, press < New > key can pop up the new window, the programming method has two kinds, the customer is used to choose to use (the following chart), a new workpiece program.

In the workpiece program under the picture on the left side of the table input contract number, figure number, size, number processing, and specifications click editing (text programming size materials and specifications with code written, not in the left side of the form fill in), programming and programming code see artifacts in editing procedure is introduced.

There are two ways to edit the workpiece program is a similar windows operating system under the Notepad text editor. Another way is use the excel files.

● Distance regulation

● Selection of punching die

● Punching

● Shear

● Font selection

● Marking

● The left / right turn over discharge

Use the button switch on the trolley station to carry on the manual operation to the feeding trolley and the feeding frame. Commonly used manual operation is as follows:

● Carrier forward / backward

● Clamp / release

● Clamp up / down

● Stage forward / backward

● Flip rack

Axis positioning

Using the "axis positioning" command on the upper computer can also carry out the axis movement, and can accurately locate the. In the main screen to select the "machine monitoring" menu "axis positioning" command, the system pop-up axis positioning window , prompts the user to enter the corresponding axis position.

The user can mm for the unit to enter the new axis position, enter, the shaft will automatically forward or backward to the specified location. If the position of the input exceeds the limit of the soft limit parameters, the system will refuse to perform the positioning operation.

Automatic length measuring

The exact length of the blank to be set in the preparation of the nesting file. This, of course, can be determined by manual measurements, however, because sometimes the blank is too long, the manual measurement is not easy. It can be easily accomplished by using the automatic length measuring function provided by the system.

Before automatic length measuring, adjusting knob to automatically in the adjustment of status, user to blank and clamp, and to ensure that the blank front end can not exceed the first test switch long. In the row of the window, click the automatic length measurement command, the system prompts the prompt window, prompting the user to do the preparation.

Press OK button to start length measurement, the X axis first to "back to the reference speed" to move forward, arrived at the first test switch long after the slowness, until you reach the second length measuring switch, X axis is stopped, the system calculated moppet material length, length measurement is completed, screen shows the length measurement result. At the same time, it will be measured long knot fruit memory within the system, to preparing discharge when using.
