DMC TOPMETAL
Innovative design for excellent production performance
Dmc Topmetal is designed to meet all deburring and satinizing demands, including heavy-duty machining. Wet processing is ideal for customers requiring very high quality finishes such as preparation of surfaces for mechanical polishing, chrome-plating and other galvanising processes.
Dmc Topmetal contact rollers are available with a diameter of 250 mm or 320 mm. The latter, thanks to the larger contact surface with the workpiece being processed and greater ability to absorb any defects on the abrasive belt joint, are specifically indicated for all applications requiring very high quality finishes. The contact rollers are available in bare steel or with an oil and heat resistant rubber coating (with hardness from 20 to 85 shores). They are also fitted with a special helicoidal grooving, optimised to ensure proper cooling and to improve ejection of machining debris.
Description
Main equipment
• Hydra V-pad control panel with 10.4” touch-screen with 120 working programs
• Air filtering unit on top to clean air containing oil mists (opt.)
• Motors positioned inside the machine structure
• Stainless steel tank
• Drying station: the outfeeded workpieces go through a cleaning and drying station (opt.)
• Fast locking system of the working units
• On/off positioning for the working units
• Working unit motors are driven by inverters (opt.)
• Infeed over thickness detection
• External tank and particle collection equipped with automated TNT filter (opt)
Advantages
WIDE RADIUS: UP TO 2 MM EDGE ROUNDING
Exclusive planetary unit using gears, with disc brush rotation speed independent from the speed of the head, for a more effective deburring and edge rounding up to 2 mm even on plates larger than 1 meter.
UP TO 25% MORE PRODUCTIVITY
Contact rollers up to 320 mm diameter for a larger contact surface and damping of abrasive belt junction to guarantee a 25% higher productivity than smaller contact rollers.
SHINE FINISHING: THE BEST FINISHING FOR UNIFORMITY AND QUALITY
Batteries of 25 nozzles located before and after every working unit for a proper cleaning and cooling of the working area: this means surface finishes up to P2000 grit and greater lifetime of abrasive belts.
ADAPTIVE CYCLE: POSITIONINING AT 0.01 mm PITCH
Electronic adjustment of the operating units is achieved with brushless motors, managed by the machine PLC control, for fast and precise positioning with reliability over time, based on abrasive belt consumption.
