Effectively and Efficiently Remove Chips and Debris from Blind Holes

Published on by Tyler DanielLeave a comment

I was recently contacted by an automotive parts manufacturer that was looking for a solution for cleaning out blind holes in a variety of machined parts. After discussing the application, we settled on a 1697SS-6-CS VariBlast Compact Safety Air Gun with Pico Nozzle, 6” Extension, and a Chip Shield. The small M5 nozzle at the tip of the gun allowed them to insert it inside of the hole and dislodge the hard-to-reach chips inside of the holes.

This worked very well for removing the chips, but they were encountering an unexpected issue as these chips were now getting lodged in other areas of the part as they were ejected. They then had to visually inspect the entire part after each blowoff to ensure that everything was completely removed.

What they thought to be an ideal solution, ended up not being the best fit. They gave us a call back to inquire about an alternative solution. We offer another product, the Deep-Hole Vac-U-Gun, that is capable of both removing chips and debris from blind holes and also vacuuming it away simultaneously.

This addresses the problem of dislodged chips being caught elsewhere on the parts. Fortunately, EXAIR offers an unconditional 30-day guarantee for all stock products. They were able to return the previously purchased gun and apply the credit towards the purchase of the Deep Hole Vac-u-Gun system.

The Deep Hole Vac-u-Gun is a low-cost solution to quickly remove chips and contaminants from grooves, containers, and drilled holes. In applications where simply blowing the debris out of the hole isn’t suitable, simply position the Deep Hole Vac-u-Gun over the hole and press the trigger. A small blow tube (3) dislodges and lifts the chips while the large suction tube (5) vacuums them away. The operator is then protected from flying debris since the contaminants are then contained within the suction tube and directed into a filter bag or other container with the included vacuum hose.

Sometimes we don’t always get it right on the first try. But, with the ability to take advantage of the 30-day guarantee we’ll make sure to get the best product to you for your application. With same day shipments with orders received by 3:00 ET for stock products, EXAIR can get a solution out to you quickly!

Deep Hole Vac-u-Gun – Blow Chips Loose and Vacuum Them Away in One Step!

Published on by Leave a comment

Last week, we looked at the Vac-u-Gun, and you can take a look at that blog here.

This week I wanted to present the Deep Hole Vac-u-Gun, a special iteration of the Vac-u-Gun, designed to provide a solution to the troublesome process of cleaning cavities and drilled holes.

The Deep Hole Vac-u-Gun is a low cost solution to quickly remove chips and debris from grooves and drilled holes where blow gun could create potentially hazardous flying debris. The Deep Hole Vac-u-Gun is simply positioned over the hole, and the trigger squeezed and then a small blow tube delivers a a stream of air to dislodge and lift the chips while the large suction tube vacuum them away. The operator is protected form flying debris since all chips and debris is contained within the clear suction tube. The device is capable of cleaning holes up to 1-1/4″ (32mm) diameter and 18″ (457mm) deep!

How does the Deep Hole Vac-u-Gun work?

How the Deep Hole Vac-u-Gun Works

 

Compressed air, normally 80-100 PSIG (5.5 – 6.9 bar), flows through the inlet (1) into an annular plenum chamber (2) when the trigger is pressed. A small amount of air is injected into the blow tube (3) to provide agitation and lift to the chips or debris. The larger airflow is injected into the the throat of the gun through directed nozzles (4). The jets of air create the vacuum at the intake (5) which draws the material in and accelerates it through the unit. The chips, debris or other particulates can then be exhausted into a filter bag or hose attached to the Deep Hole Vac-u-Gun System.

 

We have found many applications where the Deep Hole Vac-u-Gun is beneficial- including removing chips and debris in:

Holes in fixtures, drilled plastics, T-slots’groove cleaning , coolant evacuation from parts, woodworking, tapped holes, cavity evacuation, and many more!

There are many advantages to the Deep Hole Vac-u-Gun, and some are:

Low cost, no moving parts/maintenance free, durable die cast construction, eliminates shock hazard – no electricity, meets OSHA pressure requirements, safe operation – no flying chips, lightweight and portable, and quiet.

The Deep Hole Vac-u-Gun uses less compressed air than ordinary blow guns, and the amplified output flow is 12 times the air consumption rate.

Deep Hole Vac-u-Gun Specifications

Note that the Deep Hole Vac-u-Gun should not be operated without a filter bag or vacuum hose attached to the exhaust.

There are three (3) Deep Hole Vac-u-Gun System options-

Deep Hole Vac-u-Gun Systems

The Model 6094 is the Deep Hole Vac-u-Gun only.

The Model 6194 comes with a reusable bag and clamp for debris collection.

The Model 6394 comes with the reusable bag and a 10′ (3m) section of vacuum hose for transferring the debris to a collection point.

If you have questions about the Deep Hole Vac-u-Gun or any of the 16 different EXAIR Intelligent Compressed Air® Product lines, feel free to contact EXAIR and myself or any of our Application Engineers can help you determine the best solution.

The Deep Hole Vac-u-Gun = Dual Problem Solver

Published on by exaircorpLeave a comment

A little while back, I was contacted by a customer who was looking for a way to clean chips and debris out of tapped holes in an engine block. They were familiar with our products, having used them in several different areas in their plant, and had done some early research into our Air Nozzles.

They were considering using our small M4 Back Blow Air Nozzle in the process. The Back Blow Air Nozzles produce a 360° airflow that blows away from the end of the nozzle and in many cases, are the ideal solution for treating the inside diameter of hose, pipe, machined holes, etc. These unique nozzles, eliminate the concern of forcing particulate further down into a machined hole or the safety issue of blowing material out of the opposite end of an open tube or pipe.

EXAIR Back Blow Air Nozzles come in three sizes, for bores from 1/4″ to 16″ in diameter!

In this particular case, having the material blown out of the hole increased the risk of possible cross contamination somewhere else in the engine block so they were also thinking of incorporating some type of recovery system like our Chip Vac or one of our Line Vacs but were concerned with having to use two separate devices.

Once again, EXAIR has the perfect solution, the Deep Hole Vac-u-Gun. The Deep Hole Vac-u-Gun features a small blow tube (1/8″ OD) that provides a small blast of air to dislodge or loosen foreign material while simultaneously providing vacuum to carry the debris away.

If you have a similar application or would like to discuss how an EXAIR Intelligent Compressed Air Product can help solve a unique situation, contact an application engineer for assistance.

EXAIR Back Blow Nozzle: An Overview

Published on by Tyler DanielLeave a comment

In certain applications such as blowing chips or debris out of a pipe or blind hole, it may not be possible to blow forward. The pipe may be too long, making it impossible to push the debris all the way down the pipe or the other end of the pipe may not be open. In either of these scenarios, the Back Blow Nozzle is the right tool for the job. An array of holes around the diameter of the Back Blow Nozzles provides a powerful 360° airflow pattern that will clear out any leftover coolant or chips from the machining process.

Small 1004SS easily clears debris

EXAIR has three different size Back Blow Nozzles; the 1004SS (M4 x .5), the 1006SS (1/4 NPT), and the 1008SS (1” NPT). The 1004SS is recommended for use on pipes as small as ¼” and up to 1”. The 1006SS can be used for a wide range of pipe sizes, from 7/8” up to 4”. The 1008SS nozzle offers the greatest overall force for stubborn or sticky materials stuck to the inside diameter of the pipe. This nozzle is suitable for use in pipes ranging from 2”-16”. As the Back Blow Nozzle will be blowing chips and debris back out of the pipe towards the operator, it is always recommended that a Chip Shield is used. The strong polycarbonate Chip Shield will keep them safe from flying debris and keep you in compliance with OSHA directive 1910.242(b). For visual representation of the performance of the Back Blow Nozzle, take a look at this short video clip that demonstrates its use.

All of EXAIR’s Back Blow Nozzles are available with extensions. For the 1004SS we have extensions from 6”-36”, and from 12”-72” for the 1006SS and 1008SS. The Back Blow Nozzle can also be installed on our VariBlast, Soft Grip, Heavy Duty, and Super Blast Safety Air Guns. With such a wide range of available sizes and configurations, we can tackle just about any internal pipe cleaning application. If you have a process in your facility that may benefit from the use of one of these nozzles, give us a call and get one on order today!
