Can cutting fluid be used for tapping? Why do we have to use tapping oil?

Tapping refers to the use of a certain torque to screw the tap into the bottom hole to be drilled to process the internal thread, in the tapping to choose the appropriate lubricant is very important.
Key points of tapping:

1. The bottom hole of the thread on the workpiece should be chamfered, and both ends of the through hole thread should be chamfered.

2. The position of the workpiece clip should be correct, and the center line of the threaded hole should be placed in a horizontal or vertical position as far as possible, so that the tapping is easy to determine whether the tap axis is perpendicular to the plane of the workpiece.

3. At the beginning of tapping, put the tap as straight as possible, then apply pressure to the tap and turn the winch.

What is the difference between tapping and tapping

Tap is used to tap the internal thread (hole thread) also called tapping, its front and outside are threaded.

Die is used to tap the external thread, also called tapping, its internal thread is threaded, can be manually processed can also be used in the wire machine.

What is the difference between machine tap and hand tap

As the name suggests, the machine tap is fixed on the machine tool by the fixture, through the feed movement of the machine tool, to cut, the machine tap is generally only a single.

Hand taps are generally cut through a special wrench and are usually used in groups, divided into head cones, two cones or three cones.

Hand tap and machine tap have two differences:
1: The guiding edge of the two is different, because the cutting tool is different, the guiding edge design of the hand tap is long, and the machine is short.
2: The materials of the two are different, the material of the hand tap is mostly alloy tool steel, and the material of the machine tap is high-speed tool steel.

What is the difference between cutting fluid and tapping oil

Cutting fluid and tapping oil are industrial fluids used to cool and lubricate tools and workpieces.

The cutting fluid can play the role of cooling, lubrication, rust prevention, oil removal cleaning and corrosion prevention.

Tapping oil, also known as tapping oil, tapping oil, is suitable for all metals, including stainless steel, hardened steel, titanium and nickel alloys. It also has the role of cutting fluid.

Tapping oil, because of its particularly high lubricity, can effectively reduce the cutting temperature, and the cutting accuracy is greater, which is more suitable for tapping than the cutting fluid.

What are the benefits of tapping oil

Many people use manual tapping teeth, all know to add a little oil to tap out of the teeth finish will be high, thread bite will be high, tapping to refuel has become everyone's common sense, but really understand the tapping to refuel is why, the operator master is not very clear, in fact, the main purpose of tapping refueling there are three:

1: Cool down

Tapping oil can be cooled in the tapping process, when the tap is cutting, the temperature of the tap rises sharply, if the tap is not cooled, it is easy to damage the tap, which will make the strength of the tap drop sharply, affecting the durability of the tap.

2: Lubrication

When the tap is cut, if it is not refueled, the surface of the thread cut out is easy to appear rough and not smooth. Seriously affect the quality of thread.

3: chip removal

Tapping process will produce a large number of iron chips (mainly cutting taps here), iron chips are easy to stick in the thread hole and tap above, tapping oil can help timely chip removal, improve processing efficiency.

In view of these points, tapping processing is better with tapping oil, only the use of the right oil is beneficial to processing.
