We have in-house servo control Automate tapping machine which provide better production capacities with higher speed & better accuracy of threads.
We can offer repeatability in perfect thread formations.
We can also provide robust tapping on hexagon nuts after heat treatment upto grade 10 strength. This provides higher torque and better fatigue life for the nut. Sizes which we can tap start from M-24 to M-90 for hexagon nuts.
Machine is designed with Double Spindle Head which gives high production rate at the same platform with single operator, single motor, single coolant pump and double the production then in single spindle.
What is Tapping?
Tapping is the process of cutting a thread inside a hole so that a cap screw or bolt can be threaded into the hole. Also, it is used to make thread on nuts. Tapping can be done on the CNC, lathe, VMC, Automate or by hand.
We have inhouse tapping setup of 5 machines with different sizes of threads Tap. We can do Tapping in any kind of material like alloy steel, Carbon steel, Aluminum, Stainless Steel, Copper, Brass etc. Our Taps are very fine threads
which gives world best quality of thread. We provied higer accuracy of thread as per standred requierd. We use high quality of threading Tap which we import from Italy, Germany & Japan.
The each thread quality checkd by plug gauges for higer Customer satisfaction. Below image show the standard threading dimension of thread.

H = Full Height of Thread

TAPPING PROCEDURES
Good Practices
Using Tap Guides
Tap guides are an integral part in making a usable and straight tap. When using the lathe or the mill, the tap is already straight and centered. When manually aligning a tap, be careful, as a 90° tap guide is much more accurate
than the human eye.
Using Oil
When drilling and tapping, it is crucial to use oil. It keeps the bits from squealing, makes the cut smoother, cleans out the chips, and keeps the drill and stock from overheating.
Pecking
Pecking helps ensure that bits don’t overheat and break when using them to drill or tap. Peck drilling involves drilling partway through a part, then retracting it to remove chips, simultaneously allowing the piece to cool.
Rotating the handle, a full turn then back a half turn is common practice. Whenever the bit or tap is backed out, remove as many chips as possible and add oil to the surface between the drill or tap and the workpiece. Hand
