Lead Screw Tapper Modification Using AutoDrills

What do you do when a faithful customer comes along and asks for something that you don’t specifically offer?  You find someone who does offer it and pass the customer on and wish them much success. …Well, most of the time anyway because there is not always a readily available answer for the need.

This is exactly the situation AutoDrill was in just a few years ago when a customer wanted to purchase a multi-station, multiple spindle drilling and tapping set-up.  AutoDrill could meet about 90% of the customer’s need but just couldn’t fill in the gaps to make a turn-key set-up based on their rather complex needs.

That is when we turned to a machine builder and automation expert we had experience with to see if they could help.

Help they did! The JB Tool, Die & Engineering, Inc. was able to not only fill in the gap by making some custom modifications to the existing AutoDrill design, but went well beyond that by offering the customer a fully automated rotary table set-up with both the multi-drill and gang tap operations within a small footprint for maximum efficiency.

AutoDrill has worked with The JB Tool, Die & Engineering, Inc. on a number of occasions since then. We have always found them to be extremely professional and highly qualified for the projects.

Should you require an AutoDrill type set-up for drilling, tapping, or any other typical process, please feel free to contact us or reach out to The JB Tool, Die & Engineering, Inc. directly and tell them AutoDrill sent you.

How do the Professionals Drill Holes for Things Like Carburetor Jets?

Have you ever wondered how a professional drills holes?  We are not talking about your local professional wrench, but about the manufacturers.

Recently a carburetor manufacturer in Kentucky needed to drill some 1/32″ holes in brass.  They already had Dumore self-feeder drill in their shop but found that access to support and new machines was simply not up to their standards. So they contacted AutoDrill.

1100 series AutoDrill with DC Motor Set-Up

1100 Series AutoDrill for Carburetor Jet Process

After a brief discussion, it was obvious that AutoDrill’s products were of excellent quality and priced extremely competitively. So they purchased two machines immediately.

In May of 2012, the company took delivery of the drills and has been using them ever since.  Because they chose the 1100 Series AutoDrill the size of the units was kept to a minimum and their drilling fixture was extremely simple. they even chose to go with a 3500 RPM, 90VDC motor with a very simple 115VAC controller package.

The industry standard ER11 style collet chuck on the self feeding drill made it possible for them to purchase an entire set of properly sized collets for different jobs. Because these collets are available from thousands of vendors around the globe, they will never have to worry about finding proprietary items to stay in business.

AutoDrill can offer units with up to 1000 lbs. of thrust at 100 PSI and spinning multiple tools for drilling, tapping, reaming, etc.
