Stationary electrode tip dressers are among the machines that made the automated milling of electrode caps popular many years ago. Over the years, they have been modified in countless details, improved, and adapted to the current needs of our customers. They are used worldwide as a standard device.

1. DressMaster

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: DressMasters 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. DressMaster Swing

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. DressMaster Manual

There are manufacturing areas where automatic tip dressers cannot be used, e.g. if the necessary space is not available or an automated application is not feasible. In our product line we offer two different manual tip dressers:

In the simple model, the handling is completely controlled by the operator. With the “M2 Advanced”, a guide is flange-mounted on the cutter, which slips directly over the cap and completely secures the hand-held milling cutter. This makes impossible a break-out of the hand milling cutter during the milling process; the operation becomes greatly safer, and the milling result becomes accordingly more uniform and continuous.

If simultaneous milling on both sides is not possible – for example, if the pressure of the welding gun cannot be reduced to the necessary degree – the caps on the two tong halves are usually milled one after the other individually.

Both manual tip dressers take advantage of the quality advantages of the identical LUTZ milling tools, which are also used in DressMaster and CapMaster Pro. This guarantees long-term use as well as an outstanding milling result.
