Tool change time has been greatly reduced to achieve high productivity.
The cycle time for mass production workpiece machining program is compared to that of the #40 Machining Center （M/C）.
Major machining details
・φ5.1 drilling x 12
・M6 tapping x 12
・Spot facing x 7
・Boring x 2
・No. of tools used : 9
* Data taken by running machining program created by Brother
New magazine turning mechanism（ driven by AC servomotor）
The turning mechanism has been redesigned to greatly reduce the tool change time. The magazine is servomotor driven to achieve smooth turning.
The high acceleration/deceleration spindle motor used enables the spindle to start or stop in short time. Tool change can be completed without stopping the Z-axis.
* The data varies depending on the position of the spindle（ Z-axis） and program details.
The shape of the structure and arrangement of ribs have been optimized to improve machine rigidity.
As a result of various modifications, stable cutting is ensured.
Improved machine rigidity
The machine needs to be rigid to ensure high cutting ability.
The shape of the base and column, and the arrangement of the ribs have been optimized through CAE analysis.
The improvement of various internal sections has achieved stable cutting performance that does not depend on the spindle speed.
BT dual contact system is available.
Tool rigidity has improved, leading to less vibration and tool tilt, which further improves machining performance.
CO2 emissions have decreased by reducing power and air consumption.
The machine is equipped with various energy-saving functions, contributing to the preservation of the global environment.
Comparison of air consumption
The structure of the spindle covering has been enhanced to reduce air purge. Air blast operations have also been reviewed to optimize the air discharge timing. These improvements have greatly reduced air consumption.
* Data taken by running machining program created by Brother
Energy-saving effects resulting from the reduction of power and air consumption can be calculated in terms of CO2 emissions.
* The data is calculated assuming that the same quantity of workpieces (approx. 50,000 pcs.) are produced based on the above power and air consumption. The data varies depending on machining conditions, machining program, etc.
* For air consumption, power consumption of the compressor is calculated in terms of CO2 emissions.
Non-visible sections have also been modified to improve reliability, attaining higher levels of customer satisfaction.
New magazine turning mechanism
A servomotor is used to accelerate or decelerate smoothly when turning. Less backlash occurs and a highly rigid structure is used. Change to mechanical structure has greatly reduced the number of parts.
Safety measures
The number of emergency stop and door limit switch circuits has been doubled to improve safety. The number of servo relay circuits has also been doubled and the interlock circuit was reviewed.
Tool washing(Air assist type) （optional）
Discharge pressure and flow has been increased to efficiently remove chips attached to the holder.
A filter clog warning function has been added.
Usability has been enhanced to minimize incorrect operations or entries.
Various user-friendly functions have been prepared to make operation much easier.
Access rights according to user
Accessible areas of machine operation can be restricted by a combination of input signals. This prevents incorrect entries by operators that do not have sufficient machine knowledge.
* External switch or similar is necessary to apply input
