One of the most important practical examples of using system variables in a macro program


deals with the sub ject of modal data All ba sic CNC pro gram ming courses teach that the ma jor ity


CNC Flanges Drilling Machine


of data in a CNC pro gram is modal The word modal is a word based on the Latin word mo dus,


which means man ner In Eng lish, we of ten use the words mode, style, form, etc , to de scribe such


a con di tion When the same mean ing is angle machine ap plied to the CNC modal word, for ex am ple a feedrate


word F2500, it means the spec i fied feedrate has the same form, same style, same mode – it means


that it does not change, or that it is modal, un til an other feedrate word re places it The same logic


ap plies to many other CNC pro gram state ments (words), such as the spin dle speed S, off sets H


and D, and many oth ers, in clud ing most of the G-codes and the M-codes Of course, notching machine all axis data


is modal as well (XYZ po si tions)


In this chap ter, the em pha sis will be placed on the im por tance of pro gram modal val ues that ex –


ist be fore the cus tom macro is called, ei ther from the main pro gram, or from an other subprogram


The em pha sis will also be at how a macro can angle shearing machine store the ex ist ing modal val ues, change them tem –


po rarily, and re store the orig i nal ones later, when re quired


Work ing with modal com mands in mac ros is not dif fi cult, but care is needed to avoid prob lems


System Variables for Modal Commands


The 4000 se ries of sys tem vari ables (ap pli ca ble to FS-0/10/11/15/16/18/21) cov ers the uti li za –


tion of modal com mands within a macro In this 4000 se ries, there are two groups of sys tem vari –

Assignments for 64 Offsets or Less – Memory Type B


The off set mem ory Type B is quite com mon, and is found on many Fanuc lathe con trols It sup –


ports up to 64 tool off sets, more than enough for the ma jor ity of lathe ap pli ca tions


The fol low ing ref er ence ta ble lists sys tem vari ables for 64 or fewer off sets, in mem ory Type B:

This partiular section does not really belong to the chapter

 Setting This partiular section does not really belong to the chapter dealing Drilling Machine for Plate with tool off sets, but it is in –


cluded here as a re minder of the tool off sets used in pro gram ming of a typ i cal CNC lathe


In a typ i cal pro gram for a CNC lathe, the cut ting tool is called with the T-ad dress, fol lowed by a


four digit num ber, for ex am ple T0101 There is no M06 func tion for an au to matic tool change on

drill Machine


the lathe, the T-ad dress does the tool change (tool in dex ing) as well as set ting the off set val ues


The four digit num ber is, in fact, two pairs of two digit num bers The first pair al ways calls the


tool num ber sta tion on the tur ret, the sec ond pair is the off set num ber So T0101 means tool 1,


off set 1 With mem ory Type A, there is only a sin gle set of vari ables, and they re fer to the Wear


off set only There is no Ge om e try off set in Type A In the pro gram, it could be the G50 com mand that sets the ge om e try off set (G50 on lathes is equiv a lent to G92 on mills) Since this method of


set ting is to day con sid ered ob so lete, it is the Type B that is more com mon and pop u lar, us ing the


Ge om e try and the Wear Dished Head Punching Machine off sets In this case, the first pair of dig its in T0101 means se lec tion of the


tool sta tion num ber 1 on the tur ret (in clud ing the tool change) and the Ge om e try off set num ber, in


this ex am ple, also 1 The sec ond pair is strictly as signed to the Wear off set and does not have to be the same as the Ge om e try off set, al though of ten is


Al though there are CNC lathe op er a tors who to tally ig nore the Ge om e try/Wear off set dis tinc –


tion in the con trol and use only the Ge om e try off set, it is def i nitely not the rec om mended ap –


proach, Angle Punching def i nitely for macro pro grams For ex am ple, if the mea sured Ge om e try off set en try for


T0101 is Z-3750 and the Wear off set for the same tool is Z15, it is ex actly the same as hav ing


the Ge om e try off set set to Z-3735, and the Wear off set set to Z00 Not the right ap proach

The offsets are used the same as applications for Assignments for 200 Offsets or Less

Assignments for More than 64 Offsets – Memory Type B


The off set mem ory Type B for more than 64 off sets rep re sents quite a mod ern ap pli ca tion, but it


is not too com mon It sup ports over 64 tool off sets (160 listed angle shearing machine – other num ber is also pos si ble),


more than enough for some very com plex lathe ap pli ca tions


The fol low ing ref er ence ta ble lists sys tem vari ables for more than 64 off sets in mem ory Type B:

Common hydraulic unit conversion

1 m ^ 3 / s = 60000 L / min

L / min * MPa = 1/60 KW

1000psi = 68.95bar ≈ 7MPa (Europe and the United States and other countries accustomed to using psi as the unit, psi English full name Pounds per square inch.P is pounds pound, S is the square square, I is inch inches.

copper busbar machine

1kgf / cm ^ 2 = 0.1MPa (kgf: kilogram force, is the engineering unit in the force of the main unit, is a kilogram of material on Earth by the gravity)

In China, we usually describe the pressure in best cnc machines kilograms (instead of pounds), the unit is “kg / cm ^ 2”, one kilogram of pressure is one kilogram of force on a square.

How to fix the T – groove plate without foundation

T-slot flat plate is generally do not need to do with the ground connection with the ground fixed together, for example, welding, assembly with T-slot plate, etc., only need to reach the use of the site, with a few horns on the ground level You can. But some T-slot plate on the need to do a good foundation and the ground fixed. For example, motor test platform, floor boring machine table and other needs in the T-slot plate above the impact force angle cutting machine, vibration and weight of the operation. Many customers because it is not a professional installation so there is doubt, T-slot plate does not do the foundation how to connect to the ground fixed it? The following cast iron platform manufacturer for everyone to explain

1, first in the design of the T-slot plate when the ground connection with the ground to take into account some holes, that is, to the bottom of the T-slot plate cnc drill to reserve the foot hole.

2, followed by if the anchor bolts are not connected, T-slot plate directly with cement mortar fixed on the basis for the installation of light and well balanced, less vibration T-slot flat.

3, the last short ground bolts and long anchor bolts installation method is: a watering method is the basis of watering, the advance to anchor bolts, and the basis between the watering. According to the different embedding depth of the bolts, it can be divided into two kinds: embedded and partially embedded CNC Punching Machine for Sale. The advantage is to reduce the template works to increase the stability of anchor bolts, ruggedness and shock resistance; disadvantage is not easy to adjust. Second irrigation method is to water foundation, in advance on the basis of leaving the anchor bolt hole, the installation of equipment to wear bolts, and then use concrete or cement mortar to anchor the bolt holes to pour water tamping. This method is suitable for fixed light dynamic load lighter, less shock and vibration of light equipment.

based on different needs, to make the appropriate mold

Recommended the latest 80 tons of Shenzhen punch, 80 tons of precision punch offer direct punch prices 80 tons punch press is a stamping press, in the daily production and processing can be based on different needs, to make the appropriate mold, installed in the punch, out of the corresponding sample steel hole punch. Punch technology is relatively simple, compared with other mechanical processing equipment with fast, time-saving, the advantages of material. The design principle of the press is to convert the circular motion into linear motion sheet metal cutter. The main motor drives the flywheel and drives the gear, the crankshaft (or the eccentric gear) and the connecting rod through the clutch to achieve the linear motion of the slider. The movement of the connecting rod is circular motion hydraulic angle cutting machine. 80 tons of precision punch presses, please click contact us.

Technological innovation to promote the development of China ‘s punch industry

Technological innovation to promote the development of China ‘s punch industry At present, China’s CNC punch press casting industry has now made great achievements in the world of CNC punch press foundry industry also has a strong strength. However, its technically still can not come out on top, the technology has become China’s CNC punch press casting industry, the next step to continue to develop obstacles. ‘With the continuous development of China’s economic level, the conditions of China’s independent innovation technology has been basically mature cnc drilling machine for beams, and vigorously develop the technology has become a CNC punch press casting industry can not wait to work’ International Mold Association Secretary-General Luo Baihui pointed out that the CNC punch press casting industry competition induction heater.

How to Improve the Processing Capacity of Press Want to improve the press punching

How to Improve the Processing Capacity of Press Want to improve the press punching ability drilling equipment, improve work efficiency is a lot of customers in the production process has been thinking about the problem, for an enterprise, the punch processing capacity of the stronger, the higher the efficiency of the benefits for the enterprise The larger. So how can we improve the processing capacity of punch it? Under normal circumstances, in order to improve the processing capacity of the press, to start from the device structure, including the lifting device, rodless cylinder, connecting rod, feeding arm and pick arm, the lifting device set up two symmetrically fixed The rodless cylinder being located above the table and having its two ends fixed to the tops of the piston rods of the two lifting devices respectively; the connecting rods being parallel to the rodless cylinders, the middle of which is connected with the movement of the rodless cylinders And the feeding arm and the feeding arm are horizontally fixedly connected with two ends of the connecting rod and are perpendicular to the connecting rod and located on the same side of the connecting rod busbar bending machine manufacturer.

The workpiece on the mold corresponds to a disc electromagnet or a vacuum chuck. The utility model has the advantages of simple structure, low cost, and automation of the workpiece and the sheet material conveying, greatly improving the working efficiency of the press and reducing the labor intensity and the danger of the operation.
