Demystifying the Working of the BK Mikro

BK Mikro is an exceptional broken tool detection system engineered by Techna-Tool. Although the primary function is to look for any damaged tools in a CNC machine, it can also be used to look for any defects in a part, to inspect objects, and for position recognition.

How Does the BK Mikro Work?

(Applies to all BK Mikro models)

Techna-Tool’s BK Mikro systems consist of a scanner (also called a sensing head or probe) and a controller. This scanner is used to check the position of the tool being used in the machinery by means of a rotating wand that touches the tool. A servomotor and encoder help in this process. The BK Mikro ‘learns’ the position of each tool/object and stores them in the controller’s memory.

BK Mikro – Scanner Types and Specifications – Part 2

In the last blog post, we had a general discussion about the BK Mikro tool detection system. The blog also discussed the first three types of scanners that are specially designed for the BK Mikro system. As a continuation, this blog discusses the remaining three types of BK Mikro scanners available at Techna-Tool.

  • TK94A/TK94RL:TK94RL variant Available in two variants, TK94 scanners are ideal for applications in hostile environments consisting of a large quantity of coolants. Both TK94A and TK94RL models are perfect for checking tools in lathes, transfer lines, and gun drilling machines, among others. Consider choosing TK94A variant when tool scanning is required in one direction, either clockwise or counter clockwise. However, the TK94RL variant would be the best choice when scanning in both directions (Clockwise and counter clockwise without stopping) which is helpful for cost savings by only needing one scanner for 2 tools.

Techna-Tool at TECMA2013

Since 1991, TECMA has been Mexico’s only trade show strictly specializing in machine tool technology. Over 260 exhibitors from 16 different countries are expected to gather in Mexico City to show off their latest machine-tool products and share valuable information about the future of the industry.

As a leader in the machine-tool industry, Techna-Tool is excited about attending and exhibiting at TECMA2013. This year’s show, which is being held at Expo Bancomer Santa Fe in Mexico City, will run from March 5-8 and should feature a number of different talks and presentations from some of the biggest names in the industry.

BK Mikro TK8A: How to Check Tools without Losing Cycle Time

Nothing slows you down like broken tooling; everything comes to a screeching halt, and unfortunately, it can sometimes mean for hours of lost productivity. At Techna-Tool, we hate wasted time (and money!) as much as you do, that’s why we created the BK Mikro TK8A. Our innovative TK8A is a scanner made specifically to detect broken tools inside the tool changer without losing machining time.

Immediate Warranty for Tool Error Detection

It only makes sense that the credibility of a tool promising error detection, created by a company priding itself on problem solving, hinges on its reliability. We get that the reliability of your machinery depends on the reliability of our products. That is why at Techna-Tool, we strive for flawless rather than functioning. We are so confident in the quality of our BK Mikro and its ability to monitor your tools and/or parts that we offer a 3-year, immediate replacement warranty.

Knowing how valuable your time is, there’s no time for questions. The priority is getting an effective monitoring system back on your tool right away.  However durable our product (the BK Mikro can be soaking in oil or other liquids — submerged under 3 feet of coolant even — and still perform up to standard), we know that sometimes the unexpected happens. Our customers have shipped back broken tools and without a single ‘if’, ‘and’, or ‘but’, we’ve sent them back a shiny new one.

Will It Blend?

Have you ever wondered what would happen if you put your iPad into a blender? Maybe the thought intrigues you, or it might possibly make you cringe – but either way, the great folks at BlendTec made quite a splash on YouTube doing just that!

So far over 14 million people have watched Blendtec’s Tom Dickson attempt (and succeed) in this one blending mission. However, the fun doesn’t end there, if you visit BlendTec’s YouTube page there are a plethora of equally interesting and hilarious “Will It Blend?” videos.

BK Mikros Sales Are on the Up and Up

It’s true that American manufacturing output has slowed these last couple months. June and July saw either minimal or negative growth in the industrial sector. But June and July are two lackluster months out of 30-some months of solid gains posted in the US manufacturing sector. Politicians, pundits, and investors alike – those who used to write off America as an industrial has-been – have been forced to reassess their tune: American industrial orders are far above those during the worst years of the Great Recession, besides being extensively more than 2011. Big Three auto sales are not only up, but are in fact skyrocketing. Industrial and transportation jobs are there for the taking across America (though there seems to be a corresponding nationwide lack of skilled industrial workers able to handle all these new production and shipping jobs afforded them).

How Our BK Mikro Works with CNC Swiss Machines

Recently we talked about some of the general capabilities of our BK Mikro series of broken tool detectors. While we gave a clear, general portrait of how the BK Mikro improves the efficiency and lastingness of machine lines, we also know that we’re just scratching the surface as far as its specific applications. This week we’re interested in taking some time to discuss our BK Mikro again, but with a greater focus on specific applications. Namely, we’d like to assess the BK Mikro in conjunction with Swiss machines: how the two systems interact, and how Swiss Machinery can benefit specifically from using our BK Mikro system.

Swiss screw machines are automated lathes which, by way of rotating at rapid speeds, are able to “shave” the fine edges of a piece of metal down to an extremely precise tolerance. A CNC Swiss screw machine, for example, can rotate a component at a walloping speed of 10,000 rpms, and additionally is able to achieve accuracy of somewhere between 0.00002 – 0.0005”. Almost needless to say, the rapidity by which these machines rotate can easily affect the accuracy of the tools, and can even cause breakage for either the parts being made or the tools that are making them.

Our BK Mikro Is Now in the Service of GM and Ford

No matter how many new innovations and efficiencies you put into the automated production of a part, the machining process is always going to be involved.  In other words, with today’s technology, the speed with which a standard component can be built has little to do with the complexity that goes into building it. The various operations that “eliminate” human error on a transfer line are still eventually prone to wear-out, breakdown, and failure. What, then, is a company to do to maintain the timeliness and quality of its production process, when even automated operations are prone to malfunction and breakage?BK Mikro If GM or Ford, for instance, is building an engine block for an automobile and is reliant on a process that (for the most part) is not under human supervision, what happens when an unwatched system malfunctions suddenly and there’s no-one to see it? The answer lies in finding a technology that keeps track of each operation’s proper functioning. That’s where our BK Mikro comes into play.
