CNC Metal Sanding Machine: Controlled by Siemens PLC, Delivering Precise Industrial Surface Finishing

In the field of industrial manufacturing, enterprises have long been plagued by inconsistent surface quality caused by manual sanding—such as uneven processing thickness, scratch formation, and low operational efficiency. Our DRG series CNC metal sanding machine, equipped with the Siemens intelligent control system, achieves micron-level processing accuracy and automated operational efficiency that is unattainable by manual operation. For manufacturing enterprises pursuing lean production, this equipment is a core tool to improve product quality and reduce production costs.
The core competitiveness of this equipment lies in its advanced numerical control system. It is equipped with a Siemens Programmable Logic Controller (PLC) and a high-definition touch screen, allowing operators to input processing parameters (thickness, speed, grinding intensity) with one click without the need for professional technicians. The high-precision servo drive system ensures a repetitive positioning accuracy of ±0.01 mm and enables precise material removal control for plates with a thickness of 1 mm to 110 mm. Whether processing 1 mm thin aluminum plates for electronic devices or 100 mm thick carbon steel plates for heavy machinery, the equipment maintains consistent sanding results, reducing the product thickness deviation from ±0.5 mm in manual processing to ±0.03 mm.
Versatility is another core advantage of the equipment. Its modular design supports the combined use of various grinding consumables such as abrasive belts, roller brushes, and disc brushes, enabling integrated processing of derusting, deburring, wire drawing, and polishing in one single operation. The equipment seamlessly adapts to the processing requirements of stainless steel, carbon steel, aluminum, copper, titanium alloy, and even composite materials such as carbon fiber plates. For example, in the auto parts industry, it can perform sanding on brake pads to remove burrs and oxide layers. The feeding speed of the equipment can be adjusted within the range of 1-20 meters per minute, flexibly meeting the different needs of small-batch customized production and large-scale mass production.
Efficient operation and cost savings are the direct benefits brought by this equipment. Compared with the manual sanding efficiency of 20-30 pieces per hour, this CNC equipment can process 100-200 pieces per hour, increasing efficiency by 5 to 10 times. A precision sheet metal factory in Qingdao introduced 2 sets of this equipment, replacing 8 manual operators, cutting labor costs by 64,000 US dollars annually and increasing production capacity by 300%. The equipment is equipped with highly durable grinding consumables with a service life three times that of traditional consumables; the automatic tool wear compensation system further extends the service life of consumables by 20%, reducing the maintenance cost of the equipment by 40%.
The equipment can be seamlessly integrated into intelligent production lines. It is pre-equipped with communication interfaces for easy connection with robotic loading and unloading systems and Manufacturing Execution Systems (MES), realizing real-time monitoring of processing data and process optimization. It is an ideal choice for building "unmanned workshops" in the Industry 4.0 era. In addition, the enclosed dust collection system equipped with the equipment can collect 99% of metal dust, complying with the ISO 14001 Environmental Management System standard, while protecting the health of operators.
The equipment has achieved remarkable results in practical applications. A new energy battery manufacturer adopted this equipment for sanding battery casings, reducing the surface roughness of the casings from Ra 1.2 μm to Ra 0.1 μm and increasing battery heat dissipation efficiency by 25%. A medical device manufacturer used this equipment to raise the one-time qualification rate of stainless steel device components to 99.8%, meeting the stringent requirements of the Good Manufacturing Practice (GMP) for pharmaceuticals.
