W series includes 9 models. Each single machine operates on different dimensions and performs, with extreme precision, on-site repairs of holes and machinery articulated joints of big and small dimensions whose disassembly would result in a machine stop and transportation to a workshop. Statistically the use of this innovative equipment reduces of 85% the machining time.

The machines perform, with one single and simple set-up, on site work for:

• in-line boring
• internal and external overlay welding

restoring any tapered or worn out hole to its original dimension, standing out for their stability, accuracy, compact size, sturdiness and safety in a smart and smooth operational way.

• Broad range of applications
• No transport costs
• Shorter machining time
• Less labour costs
• Safe, reliable performance

The electronic circuit is used to ensure greater operational safety, to safeguard from excessive strain, the rotation motor, in the event of incorrect setting of the parameters and to compensate any critical points during machining. It allows to automatically and proportionally decrease the feed speed to reach the maximum strain point of the rotation motor, in order to dynamically decrease the workload, without exceeding the stop threshold for protection. Thanks to the STP bar , it is possible to know the instantaneous work load of the rotation motor, to choose in an optimal way , the operation parameters (rotation speed and feed speed) based on the hardness of the material, the type of installed tool, the working diameter and the diameter of removal of the tool. Furthermore, the bar signals in advance the alarm condition and the subsequent  shutoff of the control panel, flashing until the recovery of the operating conditions. Power supply 110 ~ 220V 50/60 Hz with self-selection of the mains voltage, without the use of transformers or inverters, eliminating any ESPS ® electromagnetic interference, electronic management  of the torque of the two motors with electromechanical synchronization, rotation revs display,  acoustic  warning with error code rotation motor display, feed revs display, acoustic warning with error code feed motor display.

• Main switch
• Emergency switch
• right/left inverter
• right/left rotation inverter
• Potentiometer for rotation settings
• Potentiometer for feeding settings
• Switch for rapid translation shaft

The W series is characterized by: A rotation drive system

“Worm gear-helical wheel”, with permanent lubrication, patented and state-of-the-art. To obtain an elevated productivity, high performance and low noise, the mechanisms are made with 16CrNi4 steel, cemented, tempered and refaced. Particular attention has been given to the realization of the profile, to obtain a better contact among the surfaces. The wheels have a cast iron G20 hub on which an antifriction bronze fusion G-CuSn12 is applied, to optimise  performances and efficiency. Housing and flanges are made of engineering cast iron G20 UNI 5007. The commercial components used, such as tapered-roller bearings or radial ball bearings, oil seals, gaskets, lubricants are accurately selected  to guarantee high quality.

The power has reached elevated standards, the ideal thing for any applicative situation which requests motion linearity, overload capacity and load control with high inertia. Magnetized and tested one by one, they guarantee reliability and efficiency. They are characterized by:

• Permanent magnets made of calibrated ferrite, with a high coercive force.
• Multi-bladed collector to obtain a perfect commutation.
• 4-poles tacho generator  with rare earths magnets built into the motor
• IP54 protection level
• Skewed armature for smooth running at low speeds
