BIG DAISHOWA offers a range of boring inserts-including pressed and ground geometry-designed to optimize performance and extend tool life. There is a variety of geometries available in coated and uncoated grades.
The EWE 2-152 digital fine boring heads seamlessly connect to BIG DAISHOWA's user-friendly smartphone and tablet app. This integration simplifies the process of monitoring and configuring the boring head during the assembly and operation of boring tools. The app enables users to track changes in cutting diameter and helps operators determine the optimal cutting parameters for their tool assemblies. Additionally, the heads feature variable length adjustments for toolholders, ensuring the shortest and most rigid tool assembly possible.
The EWN Smart Damper is designed for precision deep-hole machining, allowing for high cutting parameters that result in short cycle times, improved surface finishes and enhanced metal removal rates.
The modular CK system is fully compatible with all machine tool interfaces, allowing for the possibility to create tool assemblies tailored to specific requirements. Optional features, such as anti-vibration technology, balance compensation and digital readouts, are all available from stock.
Modular components from BIG DAISHOWA are based on a cylindrical connection with radial locking screw. The CK modular precision tool system has continuously evolved to meet customer needs and adapt to the increasing performance of machine tools.
Vibration is a slippery slope. You could have the ideal tooling set-up for a given application and still encounter unforeseen issues. In precision boring operations, vibration can slow you down, cause excessive tool wear and even result in scrapped parts. The specific factors that can contribute to vibration are myriad.
BIG DAISHOWA Inc. offers the following tooling strategies to help shops combat vibration and improve efficiency, precision and tool life.
Choose the Best Anti-Vibration Tech
The fight against vibration starts at the machine, but what if your machine tool is not quite a spring chicken? For older machines and applications that require extremely tight tolerances, tooling tech can go a long way. The EWN Smart Damper, for instance, combats vibrations and reduces chatter in deep-hole finish boring. The Smart Damper works via a passive damping mechanism that counters vibration with high-resonance friction action. Smart Damper components are designed to be modular, enabling longer tool assemblies that address vibration as close to the cut as possible.
It is not just for a better finish-the Smart Damper system enables higher speeds and feeds to improve cycle times by up to a factor of 10.
Think Smart with Modular Solutions
Common logic tells us that modular tooling can cause problems with rigidity. It is true that when using modular tooling systems to achieve extension, fewer connections are better. But in complex and deep-hole boring operations, longer tools may be inevitable.
Here, several approaches to modular tooling can reduce vibrations:
- Lighter, higher precision modular parts combat issues with tool assembly weight, reducing vibration and tool change issues. BIG DAISHOWA modular tooling allows greater flexibility with modular connections without compromising precision.
- In specialized cases, a different type of modular assembly can help: adding a guide bushing around the tool to guide the tool in the hole in a more rigid way. This solution calls for slower cutting and careful observation, so seek application support from a trusted tooling partner.
- Do not get your modular tooling from just anywhere-each piece of a modular system must be even higher quality and more rigid than single-tool solutions to make up for the incremental loss in rigidity as connections are added.
Compensate with Digital Boring Heads
For boring applications that require tight tolerances or where challenges increase the risk of oversized or undersized holes, digital boring heads can offer a bit of insurance and significantly speed up production. Digital boring heads allow operators to make high-precision adjustments faster and easier. What is more, models like the EWE 2-152 digital fine boring head allow for variable length adjustment of the tool holder for the shortest, most rigid tool assembly.
Select the Right Insert
The right tooling insert to reduce vibration in boring is a high-quality, ground insert with a sharp cutting edge to reduce tool pressure. Beyond that, lead angles matter. Longer lead angles may allow you to increase speeds and feeds, but lead angles closer to 90° apply the least amount of radial pressure against the tool. Less pressure means less vibration-and better productivity and tool life.
Minimizing vibration to achieve optimal results and productivity is a team effort-not only from the many physical components at play, but application experts who can help guide your team to the best solution.
