1. Tip Dresser, Stationary 0.67.S0 Series.
Stationary electrode tip dressers are among the machines that made the automated milling of electrode caps popular many years ago.
- The Axial Stroke Compensation: Even hard shocks of the welding gun are equalized, and the machine remains undamaged. The built-in rubber buffers allow stable yet flexible compensation.
- The Milling Speed: LUTZ tip dressers rotate at about 260 RPM.
- The Quick-Change Mechanism: Milling tools have to be capable of being changed in the field at lightning speed. No time-consuming screwing is required at LUTZ, as the bayonet lock allows for a non-interrupting changing process.
- For use in the VW Group, the milling tool V.00 series is released and in use worldwide.
2. Electrode Cutter for Stationary Welding Tongs 7.60 Series.
For stationary welding guns, the tip dresser must be as flexible as a robot in order to “approach” the cap. The internal “swivel” devices are so mature in their product evolution that a maximum number of use cases can be covered using them.
These include, for example:
- electromotive pivoting
- pneumatically displaceable linear unit
- control via bus systems
- adjustable cutter position (up to 1.0 m from the pivot point)
- defined TCP points and distance measures
3. Electrode Management Center 0.67 Series.
In the high-tech production lines of the automotive industry, only machines that demonstrate the highest level of stability can survive. Every device or fault reduces the number of units to be manufactured per shift. Improving productivity even further is the goal when using the Electrode Management Center.
The system is the logical continuation in the product development of tip dressers:
The advantages are obvious:
- automated welding of up to 100,000 welding points without manual intervention
- lowest cycle times of the change process under thus no standstill
- high process reliability through permanent monitoring of all work steps
It can be assumed that almost all possible cap pairs can be used, e.g. also various caps within a pair of welding tongs.
The steadily growing quality requirements mean that we now deliver these systems worldwide to countries that, until recently, preferred simple solutions. These are usually areas in which a larger number of welding points, welding robots with high cycle frequency, and the need for the highest precision are in use.
