Condition: excellent (used), Year of construction: 2011, The 2-axis WP CNC-T cleaning machine is an excellent example of a device that combines a machine built on the basis of the most modern components with high efficiency and the most favorable price. This machine operates on the basis of linear motor technology (magnetic cushion), allowing for long-term operation of the device. The set of tools with which the machine is equipped allows for cleaning the most common PVC profiles on the market. The basic machine is a strong, stable frame made of structural steel. The control panel is equipped with a PC computer. Basic equipment: Working arm: The working arm is driven by a linear motor (no clutches, gears, racks, lead screws). The linear motor moves at a set distance from the magnetic strip - no friction!! Linear motors (for the "X" and "Y" axes) are numerically controlled. Air cushion the working arm weighing several dozen kilos during the movement in the "Y" axis is supported by a pneumatic actuator - it constantly supplies pressure of a fixed value, which balances the weight of the arm. This solution allows for the use of short working times without the need to expose the machine components to the risk of rapid destruction.

Year of construction: 2025, condition: new, DOLFIN-kbn2 series parts washing machines are used for the purpose of washing the parts, which are also larger in size and heavy, requiring rinsing, passivation or another process, particularly after washing. While it is desired to have no oil and other contaminants on the surface before assembly or packaging at the businesses and factories manufacturing parts in masses, it may also be necessary to remove the washing chemical used in the 1st stage from the surface of the part according to the utilization areas of the part. For this requirement, rinsing or a similar implementation in 2nd step is compulsory. Our KBN 2 series parts washing devices are special devices that contain more than one tank and/or bath. Iodpfx Absv S Dihs Iea While the parts that are placed in the device are rotated on their own axis by means of the washing basket, pressurized detergent hot water is sprayed. With the pressure, temperature and chemical effect, all oil and contamination on the part is cleaned. After the washing process and following the direction of the washing chemical to its own tank, the rinsing operation starts in the 2nd tank. If desired, the 3rd tank can be added and another function is added after rinsing. Since Dolfin Parts washing machines operate as closed loop, new water and new detergent are not used every time. While washing is performed for several times with the same tank, all the dirt remains in the washing cell. With this feature, it protects both nature and employees. Due to its high efficiency and performance, saves energy, water and labor. The device automatically completes the loop in accordance with the values of the washing parameters that have been entered from the control panel before operation. All processes are carried out with specially prepared programs along with PLC. In order to load, particularly the heavy items into the washing basket or to remove them from the basket, the washing basket can be taken on a carrier trolley, in other words, from the device when required. It can be transferred to any point of the workshop with this trolley. We produce for you with 40+ years of experience! We export to more than 30+ countries with quality and trust.
