Advantage NFC – Reading the operating data

 

The operating data is recorded and stored by the electronics integrated in the Speedsynchro® Modular/NFC. The readout of data is done via an NFC-enabled smartphone.
The required app can be downloaded free of charge for iOS from the Apple App Store or for Android operating systems from the Google Play Store.

NFC function with iOS or Android operating systems
The readability of data using NFC with Android operating systems depends on the technical specification of the smartphone. The first smartphones with NFC function were launched in 2008.
iPhones with iOS support the readout of NFC tags from iPhone 7 along with a suitable NFC reader app.

Speedsynchro® electronics
The electronics of the Speedsynchro® system are embedded and protected under the silver cover, the NFC readout antenna is integrated inside. Depending on the operating condition, the electronics are in active mode or in energy saving mode.
Power is supplied by a battery integrated in the Speedsynchro® Modular/NFC, the charge state of the battery can be read via NFC. The battery has a service life of several years and is easy to replace. The operating data is not lost when the battery is changed.

Reading the operating data
The operating data is read out via wireless coupling of smartphone and Speedsynchro® antenna. The Speedsynchro® antenna is located under the silver cover. The position of the antenna in the smartphone depends on manufacturer and model.
For coupling and reading the operating data, it is sufficient to move the back of the smartphone in direct contact or within a few millimeters over the silver protective foil. Depending on the specific model of the smartphone, the EMUGE app opens automatically and the operating data can be read. If the app does not open automatically, it must be opened manually before coupling the devices.

Additional advantages of the Speedsynchro® Modular/NFC
  • Simple programming as synchronous cycle with feed programme adapted to the transmission ratio
  • Evaluation of time benefit of the Speedsynchro® Modular/NFC compared to a synchronous cycle by a “simulation” without Speedsynchro® Modular/NFC and tool
  • Accurate thread depths. No variations in thread depths associated with conventional tapping attachments since the Speedsynchro® Modular/NFC in contrast to tapping attachments does not reverse the sense of rotation
  • The reversal of the threading tool is done by the machine drive spindle:
    – No switching components in the Speedsynchro® Modular/NFC
    – Low wear and longer maintenance intervals
    – Maintenance independent of number of threads produced

Advantage Savings in cycle time

 

The cycle time saving for thread machining is 20 – 50% and depends on the operating conditions.

The reduction can be determined by simply changing the CNC program. To do this, reduce the spindle speed by a ratio of 4.412 and increase the feed per revolution. (refer to Kinematics) linked

  1. Measure current thread cycle time
  2. Measure thread cycle time without tool / component with modified program
  3. Increase spindle speed to 2000 rpm (max. Speedsynchro spindle speed = 8824 rpm on threading tool) and record cycle tim
  4. Calculate the savings per component with the ROI calculator

Here is an example of the graphic representation of the cycle time saving for the machining of 15 M6 threads with synchronous and Speedsynchro Modular programming.

Advantage Energy savings

 

The energy consumption of the machine spindle is determined by the acceleration / deceleration to the programmed spindle speed.
The higher the spindle speed, the higher the energy consumption.
By using the Speedsycnhro Modular, the spindle speed is reduced by a factor of 4.412 due to the transmission gear.
This results in a reduction of energy consumption at the machine spindle by up to 90%.

The following diagram shows the energy consumption of the machine spindle during the production of one million M6 threads.

Advantage Reduction of axial force

 

In synchronous thread machining with axially rigid toolholders, it is known that axial forces are generated on the thread tool flanks and lead to increased wear of the threading tools.
To reduce axial forces and tool wear, Emuge has developed Softsynchro tap holders with minimal length compensation.
This technology is also integrated in the Speedsynchro Modular and leads to a reduction of the axial force at the threading tool flanks.

The following diagram shows the process improvement for a rigid spindle M6 thread with Speedsynchro Modular. Link to Tool Details

Advantage Increase in efficiency

 

Using the Speedsynchro Modular significantly reduces the cycle time of the threading process and increases the number of components produced.
On the basis of the machine hour rate, the thread manufacturing costs can be assessed on the basis of tool holder costs, cycle time and energy savings.
For your specific application you can easily calculate the cost reduction based on your application data with the help of a ROI calculator. (linked: advantage cycle time saving)
