--- title: CrossMaster DD 300 | Metal Polishing Machinery and machines for metal finishing description: Efficiently deburr and round edges of small parts with the CrossMaster DD 300 and DD 200 Mini, designed for versatility and ease of use in various applications. --- # CrossMaster DD 300 For deburring and edge rounding of small parts in working widths of 200 mm or 300 mm. ## CrossMaster DD 300 The CrossMaster DD is equipped with two disc tools on the top. Depending on the application it can be used with deburring and/or edge rounding discs. The disc tools push the workpiece against the feed belt during operation so it is possible to process even very small workpieces starting from 20 x 20mm. The Crossmaster DD is available in 150 or 300mm working width.

The workpieces are placed on a high-friction feed belt. The disc tools, which are parallel to the workpiece, push the workpiece against the feed belt during operation. As a result, it is possible – on a disc-only machine – to process even very small workpieces starting from 20 x 20 mm. There are two models to choose from: **CrossMaster DD 300S:** Heavy-duty model with 300 mm working width with a wide range of options. **CrossMaster DD 200 Mini:** Compact model with 200 mm working width, well equipped as standard, without further options, but at a very good price. - Two rotating discs in a row - Disc diameter larger than conveyor belt width, processing from two directions - Uniform tool wear regardless of the position of the workpiece on the conveyor belt - Simple and quick tool change for material mix, as only 2 tools need to be changed - Versatile application options due to the large variety of available tools - Low investment, tool and operating costs The CrossMaster DD 300S is the heavier version, with a working width of 300 mm. Depending on requirements, the machine can be equipped and customised with various options. The CrossMaster DD 200 Mini is a compact machine with a working width of 200 mm. Due to its compact size, it can easily be used without a workpiece return conveyor. The machine is well equipped as standard, with motorized thickness adjustment, digital display, inverters and a feed belt cleaning brush. Use the CrossMaster DD 200 Mini as an additional machine for processing small parts faster, with less energy and without the risk of damaging a larger machine with small parts. ### Possibilities - Deburring and edge rounding of laser cut, plasma cut, water cut and punched parts in one pass - Deburring and edge rounding of 3D punched parts - Processing of small parts starting from 20 mm x 20 mm - Processing of foil covered or zinc plated parts - Processing of steel, stainless steel and aluminium - Max. working width: 200 mm or 300 mm - Shortest workpiece length: 20 mm - Sheet thickness: 0.3 mm – 80 mm - **Vacuum Device - **For holding down smaller and lighter workpieces. For most applications the vacuum device is often not required but it can be ordered at a later stage should it become necessary. - **Quick-Fix Tool Connector - **Quick-Fix tool connector for speedier changing of discs  e.g. when alternating between steel and stainless steel. - **Dust Extraction Unit - **Loewer offers a range of dust extraction units for removing harmful abrasive dust. Depending on the application they are available for wet or dry processing. - **Pneumatic Weight ****compensation - **Weight of the arm and grinding pressure pneumatically adjustable for more comfort. ## Gallery ![loewer-crossmaster-dd300s](https://ammachinerysales.com/hubfs/images/Machines/CrossMaster%20DD%20300/loewer-crossmaster-dd300s.jpg) ![loewer-crossmaster-dd300s-open](https://ammachinerysales.com/hubfs/images/Machines/CrossMaster%20DD%20300/loewer-crossmaster-dd300s-open.jpg) ![loewer-crossmaster-dd-300s-tischverlaengerung](https://ammachinerysales.com/hubfs/images/Machines/CrossMaster%20DD%20300/loewer-crossmaster-dd-300s-tischverlaengerung.jpg) ![loewer-crossmaster-dd300s-einlauf](https://ammachinerysales.com/hubfs/images/Machines/CrossMaster%20DD%20300/loewer-crossmaster-dd300s-einlauf.jpg) ![loewer-crossmaster-dd300s-panel](https://ammachinerysales.com/hubfs/images/Machines/CrossMaster%20DD%20300/loewer-crossmaster-dd300s-panel.jpg) ![loewer-crossmaster-dd-300s-entgraten-verrunden](https://ammachinerysales.com/hubfs/images/Machines/CrossMaster%20DD%20300/loewer-crossmaster-dd-300s-entgraten-verrunden.jpg) ![loewer-ga-crossmaster-dd-smartflex](https://ammachinerysales.com/hubfs/images/Machines/CrossMaster%20DD%20300/loewer-ga-crossmaster-dd-smartflex.jpg) ![loewer-crossmaster-dd-300s-entschlacken-runden](https://ammachinerysales.com/hubfs/images/Machines/CrossMaster%20DD%20300/loewer-crossmaster-dd-300s-entschlacken-runden.jpg) ## Demonstration VIdeos ![loewer-crossmaster-dd-300s-entschlacken-runden](https://ammachinerysales.com/hubfs/images/Machines/CrossMaster%20DD%20300/loewer-crossmaster-dd-300s-entschlacken-runden.jpg) #### Video CrossMaster DD 300S
