How an Automatic Center Punch Works: What It Is & The Working Mechanism?

Once you become a pro in the business, you’ll tend to find drilling quite easy and manageable. However, the beginning phase will need you some added stuff that supports for complicating works. An automatic center punch is most probably going to live quite on top of that list.

Even professionals want to use this amazing tool because of the simplicity and time-saving elements it provides. Here’s everything you need to know.

What Exactly Is This Tool?

An automatic center punch is basically a fat looking pen-sized tool. It comes with a simple firing pin that helps to work the tool as a hammer. With applied force, this tool easily punches a hole in literally any surface.

When you deal with a drill, it can slip from the actual position because of high spinning pin. This becomes annoyingly dangerous to ruin your efforts. Then with a chisel, which is another instrument to work as a guide, a drill is capable to make a hole.

This chisel was actually the center punch that comes with a pointy end. It needs hammering for hole creation. Gradually mechanics came up with a better version, the automatic center punch. Everything was different from then and slipping screws or dangerous drilling was not a problem anymore.

Actual Working Mechanism

To understand how an automatic center punch works, you need to go through its actual parts. So, majorly it comes with three segments or section on its body that on whole operates for making punches.

The three major moving parts are punch, intermediate rod or tumbler, and hammer.

Using a huge spring at punch’s back, a loaded part is called the hammer. There is a secure cap at the very end of this punch. It helps to adjust the force of punch. Usually, a user needs to adjust by tightening or loosening it up.

There is also a stopped hole in the hammer mass. This part is usually facing tumbler. Whenever there is a punch action, stopped hole will act as a taker for the rod. It is also known for being an anvil. The automation action provider part in automatic center punch is known as tumbler.

There needs to be slight cocking with this tumbler rod. Once cocked, the tumbler is skewed with existing position. The hammer mass faces its tip and touches gently. It needs to be in a slight offsetting way to hole.

There should be a bent end in tumbler spring. This helps to push and bear back the hammer mass against spring once punch is open. So, the hammer spring can store energy for punching.

Hole Making

  • When you work on a workpiece for making a hole, the punch needs to be pressed. This will trigger the tumbler.
  • Next, the tumbler moves further back. It reaches to the point of the tapered midsection. So that it can touch the guide hole surface inside punch body.
  • In the process of going backward, tumbler will receive a push. This has to be aligned with the tool’s center axis.
  • Once tumbler reaches the very center, it slides to hammer mass’s receiving hole. This initially discharges the hammer.
  • After so, hammer mass gets the power to move forward. It gets required propelling from back spring to do so.
  • The tumbler’s tip should bottom out inside hammer’s hole. This is because of the hole not being deep enough to get inside hammer mass.
  • Eventually, the force travels from hammer to tumbler and goes through punch. Finally, it meets the workpiece, which causes an accurate hole in it.
