The stationary tip dresser distinguishes itself by its modularity:
From the simple tip dresser with stand, motor, gearbox with integrated suction, milling unit, and control box, the machine can be upgraded by means of various additional parts. These include, for example, Profinet and Interbus connections, a rotation query, etc.
- The Axial Stroke Compensation: Even hard shocks of the welding gun are equalized, and the machine remains undamaged. The built-in rubber buffers enable a stable, yet flexible compensation.
- The Milling Speed: LUTZ tip dressers rotate at unusually high revolutions for the industry. The advantages of this technology are, in particular, shorter milling times and low mechanical loads on the cap and cutter. The series HS (high speed), with approximately 760 RPM, is in particular ideal for the field of aluminum welding. In cooperation with our series 3 GG milling systems, this combination enables an effective and precise solution in the field of aluminum welding. Identical structure in the area of stand, motor, gearbox, and stroke compensation.
- 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.
2. Electrode Cutter for Stationary Welding Guns – 10.57 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:
- the optional pneumatic or electromotive part-turn actuators
- the pneumatic transfer unit at the stroke compensation
- the adjustable cutter position (up to 1.0 m from the pivot point) over 4 degrees of freedom
- the variable swivel angle (60° to 105°)
All models available in our product range are used as milling cutters. The stability of the construction and the crank drive in the case of electric motor-driven pivoting units ensures the pivoting occurs without vibration.
3. Electrode Management Center – series 10.67 and 10.68
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 modular E2 stationary tip dresser is rounded off by components to allow the time-consuming changing of the caps by hand to be completely replaced.
The advantages are obvious:
- automated welding of up to 100,000 welding points without manual intervention
- lowest cycle times of the change process, 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 and welding robots with high cycle frequency are in use, with the need for the utmost precision.
