That versatility is further enhanced by the machine's high-grip conveyor belt, which makes it possible to process parts as small as 50x50mm, or even smaller, depending on their shape and dimensions. The pressure rollers placed before and after the abrasive belt station hold the parts in place during the grinding and finishing operation.
Configuring the aforementioned abrasive belt station is a fairly straightforward process. This deburring and finishing station includes an abrasive belt system with pneumatic tensioning for easy replacement of the consumables. It has a side switch meant to either tension the belt or releases it for the user to replace it with a new one. It also includes an automatic abrasive belt oscillation system to ensure that the belt is centered and does not move to either side during the deburring or flat surface finishing operation.
The machine is controlled with the frontal panel, where the operator can turn the abrasive belt unit and the conveyor belt on and off. The DM1100 Z also has an ammeter available to read the motor’s consumption and speed selectors with variable speed (for both the abrasive belt unit, ranging from 8 to 22m/s, and the conveyor belt, ranging from 1.5 to 7m/min). A manual thickness wheel with a 1/10mm-precision display is also included.
This operation is performed by the DM1100 Z’s deburring station, which uses an abrasive belt combined with a contact roller of 180mm in diameter and with a shore hardness of 55. This specific diameter and shore hardness make for the best combination for deburring and surface finishing. Bearing this in mind, the contact roller has a fine-adjustment feature to make the deburring station compatible with abrasive belts of different grits: from a compact grit all the way to scotch-type belts (i.e., from very thick abrasive belts to very thin abrasive belts).
There are two inverters built into the machine. These are essential for any deburring and surface finishing operation to be performed on laser-cut parts or metal sheets. The deburring process usually requires the conveyor belt to move at a slower speed and the abrasive belt station to move at a higher speed. The surface finishing process requires a higher speed on the conveyor belt and medium to high speed on the abrasive belt, depending on whether a compact-grit or scotch-type belt is being used. The combination of these two inverters allows for significant efficiency gains as far as the overall process is concerned and regardless of whether the customer needs to do deburring or surface finishing. Several advantages accrue to the user, namely the fact that very little heat is generated on the surface of the material. Other perks include there being less abrasive belt wear and the possibility of using different consumables on the machine.
This deburring machine was developed to meet several market requirements. It can be integrated with the DM1100 C, its edge rounding equivalent. Both can be connected through an extra conveyor belt table to allow for a complete deburring and edge rounding process. This table transports the deburred parts from the DM1100 Z to the conveyor belt of the DM1100 C to begin the edge rounding process. Customers who already have the DM1100 C Edge Rounding Machine can increase both their capacity and available services thanks to the addition of the deburring process made possible by the DM1100 Z.
NS Máquinas has also redesigned the old DM1100 C Parts Return System, creating a new version that allows both machines to be integrated. This solution ensures that one single user can operate both machines. They can feed the machine the parts, and the return system will bring them back to the operator. Therefore, the parts can be inspected and stored in the same place. There is no need for the operator to move around the machines. This solution is designed to bring back small parts up to 250x250mm and with a thickness of up to 20mm. Another advantage is the possibility of increasing productivity when a double-sided process is required. The operator receives the part and feeds it back to the machine, turning it over so the other side can be deburred, and its edges rounded out. The system is not fixed and can therefore be easily removed so bigger parts can be done.
