What are the Main Technical Indexes of Driving Methods in Laser Cutter?

Laser cutting is now the mainstream of sheet metal processing. Due to its fast processing speed and high requirements for positioning speed and acceleration, the design of the transmission system of the laser cutting machine has a certain particularity. So what are the main technical indices of driving methods in laser cutters? The following are some of the main technical indices, which are:

1. Stroke
   The stroke represents the processing range of the laser cutter, determines how large the workpiece can be processed by the end user, and is the most basic parameter. The ultimate processing range is 3m x 1.5m. In this dimension, it can achieve a perfect balance between mechanical properties, processing range and production costs. However, with the improvement of the overall industry level, the share of large size models has been increasing year by year.

2. Positioning accuracy
   The positioning accuracy of the machine can reflect the positioning of the manufacturer and product inputs as well as the level of precision of the selected transmission parts. However, for laser cutting, the positioning accuracy cannot have a significant influence on the final processing effects such as the tolerance of the part size and the quality of the part being cut. But for some fine cuts, the laser cutting equipment can precisely cut a dozen micron slits, which is at the same level as the laser cutter operating accuracy. At this point, positioning accuracy is very important.

3. Repositioning accuracy
   The repositioning accuracy achieved by the laser cutting machine is highly dependent on the reverse clearance of the transmission chain. The reverse clearance of the laser cutting machine also has an influence on the roughness of the part. Users who are very picky about the quality of cutting parts should pay little attention to this indicator.

4. Drive
   Due to the high flexibility of laser processing, high-speed cutting of complex parts has become the main means for various manufacturers to display mechanical properties. High-speed cutting requires high output torque for the motor. So acceleration is just as important as positioning speed. And at the same time, there is a contradiction between high speed and high acceleration. This requires cutter manufacturers to carefully balance relationships and find optimal solutions through calculations and experiments.

5. Transmission stiffness
   In the high-speed processing of the laser cutting machine, the internal tension of the transmission chain can fluctuate greatly. If the transmission rigidity is insufficient, it is easy to cause track distortion and slow response of the final result, which causes the dynamic operation accuracy is far from low or static measuring value, and then affects the dimensional accuracy and roughness of the workpiece.

Good dynamic response is the common pursuit of all kinds of precision CNC machine tools. This is especially true for laser cutting machines that are good at high-speed machining. By using our laser cutting service Duta Laseindo Metal, you will get a higher precision cut and fewer laser cuts thereby greatly reducing follow-up time spent in processing.
