Innovative tool management function
Mold processing has always been one of the most challenging applications to test the performance of CNC systems.With the SINUMERIK 828D with the “Advanced Surface” function, this challenge can be fully met. This function is a unique calculation method designed to improve the surface quality of the workpiece while significantly reducing the processing time. The new “pre-reading” algorithm comprehensively considers the entire processing path, so as to ensure that the surface of the workpiece is smooth when the mold prngram is executed for a short period of approximation
Kellenberger designed new generation M8* machines to satisfy the most demanding production and precision component machining requirements in the Aerospace,Automotive, Mold&Die, Power engineering and Oil/gas industries.
*The Kellenberger M8 is distributed through its own dedicated sales organization, which also includes a service network operating to Kellenberger standards.

*The Kellenberger M8 is distributed through its own dedicated sales organization, which also includes a service network operating to Kellenberger standards.
Shorter machining duty cycle time and lower non-cutting time
Excellent static accuracy and Machining Accuracy
Extend tool life and improve heavy cutting capabilities
CMA (Continue Machining Accuracy) is an important test method to consider the thermal stability of machine.TB series machine tools are designed and manufactured for precision parts processing, with excellent CMA performance reaching < 0.0 I mm.
In order to better control the dimensional instability caused by heat sources during processing, the machine can be equipped with a spindle cooling device and X/Z axis linear scales.
Oil Cooler: The spindle is equipped with an oil cooler, which can promptly remove the heat generated by the high-speed rotation of the spindle, effectively control the temperature rise of the spindle, inhibit the thermal displacement of the spindle box, obtain better processing dimensional stability, and extend the life of the spindle.
Linear Scales: Both the X and Z axes can be equipped with high-resolution linear scales to form a full closed-loop detection, compensating for the thermal temperature rise and displacement generated by the movement of the transmission components, ensuring that the machine achieves better processing performance in mass production
The automatic centralized grease lubrication device can automatically and regularly fill the ball screw and guide rail with oil, also has the function of liquid level and pressure detection.
Grease lubrication has the advantages of easy maintenance, environmental protection, low loss, and can effectively reduce the cost of machine use. Compared with thin oil lubrication, it can reduce carbon emissions by 92% and electricity consumption by 96%.
Standard mechanical arm type automatic tool changer, 24 Tools. Tool changing time: 3.5 seconds (BTS0)/2.5 seconds (BT40), bi-direction random tool changing, fast and stable, special design of 90 -degree tool sleeve inversion to prevent tool sagging, fast and accurate.
Optional Mechanical arm-type automatic tool changer 32 tools (BTS0)/40 tools (BT40)
German planetary gearbox, double speed(2000 / 6000 rpm), high torque and herringbone belt transmission. Ensures the features of low speed with high torque and high speed with low noise.
Automatic tool setting instrument eliminates manual setting operations,reduces non-cutting time, which can quickly measure tool length and tool diameter, also could check tool damage.
Realize rapid workpiece alignment and establish coordinate system, real-time monitoring of key dimensions, determine whether the workpiece is out of tolerance and give an alarm. Effectively improve production efficiency, ensure processing accuracy, and fully improve the effective produc-tion capacity of the equipment.
Allows deep hole drilling, stainless steel and other special materials machining by supplying 20 bar high-pressure coolant to the cutting edge, quickly discharge chips and enhance to tool life and machining accuracy.
The BT40-12000 rpm spindle is equipped with a spindle oil chiller device as standard, which can effectively control the temperature rise caused by high-speed machining of the motor and improve the spindle life and machining accuracy.
