EMUGE KSN-HD-Softsynchro

Product catalog summary

Technical Description
The KSN/HD/Softsynchro® holders are engineered for CNC machining centers to synchronize spindle rotation with the feed axis. They address potential errors from machine dynamics and tool tolerances by compensating for pitch differences, ensuring high concentricity and safe clamping without special shanks.

Constructional Details
The holders are two-piece constructions for easy maintenance, featuring separated axial force compensation and torque. Plastic absorption elements minimize tool edge impact, and pre-tensioned elements control axial movement. They support up to 50 bar internal coolant pressure without affecting axial force.

Economical Efficiency Calculation
EMUGE KSN/HD/Softsynchro® holders offer significant cost savings over competitors, considering factors like component numbers, threads per tool, and annual tool costs.

Practical Application
Tests show EMUGE holders reduce axial forces compared to rigid and competitor holders, especially at higher speeds, improving tool life and thread quality.

Conclusion
The holders optimize synchronous spindle use, enhancing tool life and thread quality. Key features include torque and axial force transmission separation, pre-tensioned elastomer springs, and minimal rolling friction. For non-synchronous machines, more generous length compensation holders are available.

Product Variants
The series includes designs for different collet types and lubrication methods, with options for internal coolant-lubricant supply and minimum-quantity lubrication. Special solutions are available upon request.

Specifications
Collet holders are available with taper shanks according to DIN 69871 AD/B, ASME B5.50, and cylindrical shanks according to DIN 1835 B+E. They support internal coolant-lubricant supply, crucial for maintaining optimal tool temperature and reducing wear.

Procedures
Assembly involves inserting the collet into the clamping nut, ensuring proper engagement, and tightening with a wrench. Correct torque values are emphasized to avoid damage.

Standards and Norms
The holders conform to international standards like DIN 69871, ASME B5.50, and DIN 69893, ensuring compatibility and performance consistency.

Recommendations
Use torque wrenches like TORCO-FIX for checking torque values on clamping nuts and specific assembly sets for tightening and counter-holding during installation.

Additional Features
Some models include a bore for data chips according to DIN 69873 for enhanced data management and tool tracking. Designs with minimum-quantity lubrication (MQL) systems are also available.

Key Data from Tables
Tables provide detailed measurements and article numbers for various collet holder models, specifying dimensions like diameter, length, and thread sizes, crucial for selecting the appropriate holder.

Sealing Discs and Coolant Flush Disks
Sealing discs and coolant flush disks are available in various sizes with corresponding article numbers.

Coolant-Lubricant Tubes and Assembly Wrenches
Instructions for assembling coolant-lubricant tubes in hollow taper shanks (HSK) are provided, with specifications for different shank sizes.

Torque Wrenches and Shell-Type Wrenches
Torque wrenches and shell-type wrenches are detailed with torque ranges, lengths, and article numbers.

Clamping Technology Holders with minimum length compensation

KSN/HD/Softsynchro® Technical description On many modern CNC machining centres the rotation of the spindle can be synchronized with the feed axis. This makes it possible to produce threads with tool holders without length compensation. However, practical experience shows that even with this kind of “rigid tapping”, synchronization errors can come up. Possible causes are: • achine dynamics, harmonization of spindle and linear drives, m especially during the moment of changing the rotation direction • tolerances on the threading tool When rigid tool holders are used, these errors can lead to problems....

KSN/HD/Softsynchro® Practical application Many tests regarding this topic have been made with taps and cold-forming taps. Depending on the individual case, our customers were able to increase their tool life by up to 150%. In the following diagrams, you will find the axial forces which come into play in the cold-forming of an M10 thread in St37. We have traced the axial forces at two different speeds, 500 min-1 and 2000 min-1. The following collet holders were tested: a) rigid synchronous collet holder b) MUGE collet holder type KSN/HD/Softsynchro® size 01, E with minimum length compensation...
