How to operate and program the CNC drilling and tapping machine

How to program speed up?

CNC lathe programming drilling program: instruction format: g83 x--c--z--r--q--p--f--k--m--; X, Z is the hole base mark, C angle, R initial point increment, Q each drilling depth, P hole bottom retention time, F bucket to talk about the amount, K repetitions, M when using C axis.

It is used for deep hole drilling, and the angle of the end face is bisected to drill the hole. It is commonly used in the processing of materials with poor chip evacuation in blind holes. Precautions for CNC riders to rent a bed for programming drilling:

1. The drill bit should also be on the knife, the test drill should be on the tool, the drill bit touches the end face to the zero point of the end face, the edge of the drill bit touches the outer circle to the outer circle, pay attention to the radius of the workpiece to add the radius of the drill bit.

2. Before setting the tool, the verticality of the drill bit should be calibrated.

Otherwise, it would be crooked to get in.

3. The speed should not be too fast. Drill a little back, drill a little more. This is good for plating.

4. Add coolant.

CNC lathe programming drilling program:

Command format: g83 x--c--z--r--q--p--f--k--m--; X, Z is the hole base mark, C angle, R initial point increment, Q each drilling depth, P hole bottom retention time, F feed, K repetitions, M when using C axis. It is used for deep hole drilling, and the angle of the end face is bisected to drill the hole.

It is commonly used in the processing of materials with poor chip evacuation in blind holes.

Using two holes with a diameter depth of 10 as an example, the procedure is as follows:

Drill two holes with a diameter of 10 deep G0 x8 z1. c0g83 z-10. q3.

c180.g80 (cancel the loop).

G0 Z30 drill diameter 10 holes deep G0 X0 Z1 g83 z-10. g80 g0z50.

CNC lathes without end face power shafts only remember the second way to use it, if there is no Q parameter, it is the same as G1, drill to the end, please pay attention to it when programming.

Follow the steps below when the tapping machine is operating.

1) The position of the workpiece clamp of the automatic tapping machine should be correct, and the center line of the threaded hole should be placed in the horizontal or vertical position as much as possible, so that it is easy to judge whether the axis of the tap is perpendicular to the plane of the workpiece. The orifice of the threaded bottom hole on the workpiece should be chamfered, and both ends of the through-hole thread should be chamfered.

2) At the beginning of tapping, try to put the tap right, then put pressure on the tap and rotate the winch hand, and carefully check and correct the position of the tap when cutting, and the position of the tap should be correct. In the future, it is only necessary to turn the winch hand and no more pressure should be applied to the tap, otherwise the thread shape will be damaged.

3) When tapping, the tap and the screw hole should be kept coaxial, and the calibration part of the tap should not all come out, otherwise there will be messy teeth when the tap is withdrawn from the reverse car. It makes it easy to evacuate chips after chipping and reduces the phenomenon of taps rolling due to sticky chips on the cutting edge. When the screw hole cannot be tapped, the tap should be withdrawn frequently to remove chips from the hole.

4) When the latter tap is used in the process of tapping, it is necessary to screw it into the tapping and thread by hand, and then use the twister to twist it when it can no longer be screwed in. It is also necessary to avoid turning the winch quickly when exiting after the final cone is tapped, and it is best to twist it out by hand to ensure that the quality of the thread that has been tapped.

5) Use special tapping oil when tapping the screw holes of plastic materials. For ordinary carbon steel, copper, aluminum alloy and other materials, tapping oil containing vulcanized lard is generally used. For stainless steel and titanium alloys, it is best to use a high extreme pressure tapping oil containing sulfide fatty acid esters.

6) The cutting speed of the automatic tapping machine should be adjusted appropriately according to the different materials. In the same material, the lower value is taken for the small tap diameter, and the lower value is taken for the large tap diameter.

First of all, the 20 hole is larger, so you have to set the center hole and then program it with the G83 drilling cycle. Because in the G83 drilling cycle, chip breaking, grooming, chip evacuation, and cooling can be achieved. If you drill directly with G1, the drill bit will wear out after not drilling a few holes.

The procedure is as follows. m3 s600

M5M30G83 is to drill 3 mm once, then retreat to the starting point, 3 mm in the intake, and drill straight to the end value of the program.

The exception is that the G74 can also be drilled in cycles. But G83 is the most commonly used. It is generally not recommended to drill deep holes directly with G1.

If it is a batch product, it is more suitable to use the excellent drill, the excellent drill can change the blade, the accuracy and roughness of the drilling are relatively high, and a small margin can be left, which is conducive to the finishing of the hole. The procedure is very simple, something like this:

m03 s800 t0101

g0 x0g1g0g1g0g1g0m30

In fact, the program of the drill bit is the same as that of the turning tool. It's just that you have to drill the bit according to the drilling process. Appearance.

I think you should have no problem, and I will tell you about the precautions for lathe drilling:

1. Tool pairing: The drill bit should also be on the tool, the test drill should be drilled to the tool, the drill bit should touch the end face to the zero point of the end face, and the edge of the drill bit should touch the outer circle of the outer circle, and pay attention to the radius of the workpiece to add the radius of the drill bit.

2. Before setting the tool, the verticality of the drill bit should be calibrated. Otherwise, it would be crooked to get in.

3. The speed should not be too fast. Drill a little back, drill a little more. This is good for plating.

4. Add coolant.

This one is relatively simple, you just need to polish the 20 drill bit, Huaxia Alliance, into a square drill bit, and then hit it the thing you want to hit.

If it is a BAI Siemens system.

This is to make a copy of the bottom hole, it is best to have two drill bits, and then add a centering drill, a small bit of drill bit drilling, 20 drill bit reaming.

It's simple, M3S500 T200 G0 G1Z G0T0

The meaning is almost the same, first start the speed, give the oil, I didn't write this, each one is not necessarily the same, and then the drill bit is set to the center, G1 speed in, G1 speed out, the tool is moved away, the program is a little bit different and not much worse.

First of all, the 20 hole is quite large, so you need to set the center of the hole, and then use the G83 drilling cycle to program. Because DAO is in the G83 drilling cycle, it can not only break the chip, but also remove the chip and cool. If you drill directly with G1, the drill bit will wear out after a few drill bits.

The procedure is as follows. m3 s600

The exception is that the G74 can also be drilled in cycles. But G83 is the most commonly used. It is generally not recommended to drill deep holes directly with G1.

If you don't understand, you can ask me, I hope it will be useful to you.

Specialized Dedu

Magee drilling machine, with.

Zhiworknc programming software, the software matches the tool type, tool safety length, and process according to the hole back characteristics, size, range, depth, etc. of the workpiece, and the machining accuracy is also very high. Nowadays, with the rapid development of technology and the efficient solution of many problems, I dare not think of the time when I used to identify them one by one.

How to hand-knit drilling programs in the machining center is super simple, you can understand it at a glance, and it may help you.

First put the tapping in the center of the drill clamp in the tailstock, and then push the tailstock over do not lock, and then shake the tapping into the inner hole (as long as you go into a wire, pay attention to the number of revolutions not too fast), go into the rotation, exit the reversal, it is best to go on the general car for the silk Xie to adopt.

It depends on what system you are using. If it is Huaxing's, use g84It is KND with G93Tapping is the same as threading. Bring the pitch in the program. Thread end size. That's it. The system will automatically reverse the withdrawal.

Set the zero point of a knife holder, align the knife, and walk the knife back and forth in the Z direction. People who know craft don't ask such questions.
