Accu is the message that is displayed when the battery needs to be changed.
This message does not mean there is an error or accuracy malfunction with the boring head. The head should still continue to function for a few more adjustments. If this message appears on the EWE heads, the wireless connectivity to the App and history functions are deactivated until the battery is replaced.
NTK offers an extensive line of high precision boring tooling designed for Swiss machines. One of these produce lines is called “Mogul Bar”. The Mogul Bar system provides the user outstanding chip control and higher rigidity than most conventional tooling on the market.
Outstanding chip evacuationThe most notable characteristics of the Mogul Bar is excellent chip evacuation and chip control. Mogul Bars outfitted with NTK’s “F” or “FG” chipbreaker inserts will evacuate chips backwards.
This means that when a Mogul Bar machines an I.D. bore, chips comes out towards the bore entrance. The major-ity of boring processes on Swiss machines are done on the main spindle side and thus the bore itself is a blind hole. This machining process creates many issues if you use conventional boring bars designed for CnC lathes.
Typical difficulties incurred during a boring process on Swiss machines are either chips remaining in the bore and rough surfaces caused by inconsistent chip control. However, Mogul Bars equipped with nTK uniquely designed chipbreakers, evacuate chips straight backwards and solves both of these problems at once.
Another important feature of the Mogul Bar series is high rigidity. Mogul Bars increased rigidity is a result of a newly designed bar head configuration and a minimal flat width on the bar.
Steel shank Mogul Bars can machine as deep as L/D=5, a depth which nor-mally requires expensive carbide shank boring bars.
NTK carbide shank Mogul Bars can machine up to L/D=7 depth and this gives users flexibility of machin-ing deeper bores in a single process. rigidly and mini-mal flat widths reduce vibration.
Variety of Insert Grades
NTK offers both coated carbide grades and cermet insert grades for Mogul Bars. As most tooling engineers know, cermet grades can machine at faster speeds with higher productivity, provide better sur-face finishes and can achieve more accurate dimen-sion control, than carbide grades. These benefits come from the fact that the primary substrate of cermet grades, Tin /TiC, are chemically stable compared with WC of carbide grades and have better adhesion resistance.
Mogul Bars are available from a minimum machining diameter of 5mm. With the combination of NTK unique chipbreakers, you can enjoy better chip control and highly rigid boring bars. In comparison with solid carbide boring tools, Mogul Bars has cost advantage as well.
If you are facing chip control or chattering issues, NTK believes that Mogul Bars can be the answer to your problems.
We are very excited to announce that we are now able to offer on-site technical training to YOUR machinists at YOUR location! This is offered at no charge to customers who use any of the manufacturer's whom we represent in California and Nevada.
However, just because you don't purchase things from us, don't feel left out! We also offer on-site topic specter training on any of the following topics for $150/hour.
Each presentation lasts about 2 hours. The presentations last approximately 45-60 minutes with the remaining time for Q&A and discussion about unique applications in your facility.

Smart Damper products are designed for deep-hole boring with BIG KAISER’s CKB modular boring system, and also for extended reach milling with both inch- and metric-pilot shell mills and face mills.
The original rollout of the Smart Damper for finish boring included an integral BCV50, BBT50 and HSK-A100 tool holder with a CKB modular connection at the business end. A BCV50 integral 1” shell mill holder was also available.
This new design for boring shortens the distance from the damping mechanism to the cutting edge, which is the source of vibration. This produces higher damping effects to the tool assembly to minimize the chatter or vibration – thus achieving better surface finishes and improved metal removal rates.
The EWD Smart Damper damps vibrations and reduces chatter in deep-hole finish boring and extended-reach face milling applications – thus achieving better surface finishes and improved metal removal rates.
For precision machining of deep bores, it has previously been necessary to choose low cutting data in order to prevent vibrations, which massively increases processing time. The EWD Smart Damper overcomes this problem, and enables high cutting parameters to be used. This means that extremely short turnaround times can be achieved, which improves productivity by up to a factor of ten.
To get the maximize life our of your Steep taper rotary toolholders in your CNC milling machines here are some of the best practices you can implement in your shop. Perhaps not all of them can be implemented every day or every time but it's well worth being aware of how to best protect your investment.
Our most widely used finish boring system, KAISER Series 112, features a high precision boring head with a center-mount boring bar or boring bar/insert holder combo with a predefined fixed offset designed to bore one specific size. And although the KAISER system provides a multitude of standard components to create the ideal combination of boring bar and insert holder – you may not always have the ideal combination at your disposal. Don’t fret – that is the beauty of the system. The total boring range of your assembly is reached through radial adjustment of the bar. However, when doing so, there is still always the consideration of balance while assembling the tool. As logic would tell you, the farther away from the boring head’s centerline you offset the boring bar, the greater the unbalance. This affects not only the performance of the tool, but more importantly, the results. And this is especially true for deep hole boring.
To get the greatest productivity and flexibility from the KAISER 112 boring system, we recommend replacing the fixed bar & insert holder with a radial adjustment bar & insert holder which keeps the bar at centerline at all times. This allows for different boring ranges to be reached, all while keeping the tool as balanced as possible.
In this video, Matt Tegelman, Applications Manager and KAISER Product Manager, walks you through the process of adjusting the fixed boring bars and inserts holders. And if balance is a concern, utilizing the radial adjustable option, Matt demonstrates how to properly center the boring bar on both a tool presetter and in a machine spindle, and finally, how to fine-adjust to the desired diameter.
Watch for more of these brief instructional reference videos here on Cut to the Chase blog in the near future.
