Automatic MTE milling head diagonal Type

Automatically swiveling milling head in diagonal design, with division 2.5° x 2.5° (Hirth serration) speed 4,000 rpm. To ensure a constant temperature even at maximum load (speed and power) in continuous operation, the milling head is equipped with oil cooling for the spindle bearings. This ensures that the milling head, the main spindle gearbox, and the machine's hydraulic oil are maintained at the same temperature range, thus ensuring not only a constant but also a uniform temperature control of the machine.

The milling head housing is designed for a power of 45 kW and a maximum torque of 2,000 Nm. It is completely made of high-quality steel casting GS 60, thus offering maximum stability and long-term accuracy. The milling head automatically swivels in both planes through a cycle in the NC control and is indexed in the respective angular position in both planes via a Hirth serration. This guarantees repeatability with a precision of ± 3 sec. (equivalent to ± 0.002 mm) in any angular position.

Coolant System with 20bar & Internal Coolant Supply (IKZ):

The machine is equipped with a coolant system that ensures optimal cooling of the tool and workpiece depending on tool usage and material. The coolant exits at the milling head through flushing nozzles on the tool spindle and through the center of the tool (IKZ) according to DIN 69871 Form AD. Main tank (volume): 1000 Liter High-pressure pump brand: Grundfoss Delivery rate: 40l/min External cooling: 5 bar Internal cooling: 20 bar The coolant tank is equipped with a paper band filter system and additional cartridge filters with pressure monitoring for each channel.

Tool-Center-Point Optimization Software

This package includes cycles for the automatic determination of milling head dimensions. The dimensions are automatically measured using a radio wave probe on a precision ball, then stored and activated in the kinematic tables. Additionally, various intermediate positions can be measured and recorded. The supply does not include the measuring probe or the TCP optimization device (ball).

This software facilitates precision in milling operations by automating the measurement and adjustment process, ensuring that the milling head operates with optimal accuracy. It's an essential tool for modern, high precision machining environments, enhancing both efficiency and accuracy. 

Wireless Probe System RWP38.41:

Bidirectional activation.

Steep taper DIN69871 SK50.

Toolbox 38.41-TB.

M4 probe stylus (ceramic shaft), length = 53 mm.

Wireless receiver RWR95.40 with a flexible antenna and TNC connector.

The electronic measurement of workpieces significantly reduces alignment and setup times, enhancing production monitoring. By checking the workpieces, a consistently high-quality level of the manufactured parts is ensured.

This system is a critical component for maintaining efficiency and high standards in production. Its ability to provide precise measurements and alignments in various orientations of the milling head ensures that the parts produced meet the desired specifications and quality benchmarks, streamlining the manufacturing process while maintaining excellence in production.

Heidenhain Adaptive Control

Function and cycle for automatic feed control for optimal and constant utilization of the drive power. The automatic feed control works via the spindle power and can be changed like the speed during the process. Advantage: Longer tool life and shorter processing time.

Movable control panel in front of the machine table:
