CNC machine precision was instrumental in the development of successful CNC Machine manufacturing processes. Manufacturers must rely upon accurate CNC machines to produce precision-machined components; therefore, any minor defect becomes costly in rejected components, delays in production, and increases in operating costs for the manufacturers. Today, Laser Calibration of CNC Machines is a necessity for manufacturers if they want to manufacture perfection.
Due to increased global competition and increased expectations of accuracy, the implementation of advanced calibration solutions enables manufacturers to operate with optimal performance through the use of their CNC machines. State-of-the-art calibration solutions like CNC Machine Calibration, CNC Machine Precision Calibration, Laser Alignment and more enables manufacturers to maintain the highest levels of calibration accuracy, efficiency and reliability.
1. Detecting & Correcting Positioning Deviations on CNC Machines:
Through continuous usage and mechanical wear and tear on CNC machines, mechanical positioning errors develop on the mechanical components of CNC machines. The use of Laser Calibration on CNC Machines provides manufacturers with the highest level of accuracy through the use of high-precision laser interferometry, which is capable of identifying small deviations across all axes of the machine.
Using Laser Calibration on CNC Machines enables manufacturers to determine the following:
The correction of these deviations allows manufacturers to have a CNC Machine that meets or exceeds the global standard of machining accuracy.
2.Enhancements to the Quality of Components and the Reliability of Machining Operations
Very tight tolerances must be maintained when producing components for several different industries, this includes aerospace, defence, automotive and tooling among others. A minute discrepancy can result in a mismatched or incorrectly assembled component. Manufacturers can achieve a high level of accuracy in all machining processes, using Precision CNC Calibration systems to ensure consistent calibration abilities across all CNC milling and machining equipment.
Precision CNC Calibration improves:
The quality of the finished product improves with fewer rework, scrap rates, and overall reductions in costs due to the maintenance of consistent high-quality products.
3. Increase the Life and Performance of CNC Machines
CNC machines are an investment and should be treated as such, just like vehicles require proper maintenance and servicing, CNC machines perform best when properly calibrated. By using Laser Calibration, any stress placed on the spindle, ball screw, guide rail, and servo motors is greatly diminished. The following are some of the benefits of implementing CNC Machine Calibration:
By using routine Laser Calibration, you will prolong the life of your CNC machine and improve the efficiency of your production processes.
4. Accurate Multi-Axis Machining
Today's CNC machines are designed to perform multi-dimensional machining operations on a 3-axis, 4-axis and 5-axis bases. If there is any deviation from a required machining axis through a misalignment or error, the entire machining cycle will be distorted. When Laser Alignment systems are utilized, all axes of a CNC machine are accurately synchronized to complete very complex manufacturing and machining operations.
Laser Alignment is extremely important for the accuracy and quality of:
Laser Alignment systems will help manufacturers achieve a better level of machining stability and repeatability.
Step 1: Diagnosis of Machines Before Laser Calibration
Prior to performing any calibration, technicians perform an extensive inspection of the machine to determine whether there are any issues with performance, vibrations, wear patterns, or inaccuracies within the machine's accuracy.
Step 2: Setting Up the Laser
After diagnosing the issue, the laser interferometer will be set up in the same plane as the CNC axis that is being calibrated.
Step 3: Measuring Real-Time Axial Deviation
The laser beam detects all deviations, even minor ones in the axis that are below 5 microns, thereby allowing the technician to map the various movements of the CNC axes with pinpointed accuracy.
Step 4: Input Error Values into Controller
After determining all existing error values, engineers can input these errors into the CNC controller for compensation of the axial positions in an accurate manner.
Step 5: Error Validity to Report
After the calibration has been done, the technician will perform further testing and analysis on the machine. A detailed calibration report tracing to both national and international standards will also be produced. This process enables CNC machines to be calibrated at the highest level for the greatest accuracy and efficiency.
1. Improved productivity through high speed & high accuracy; calibrated machines can operate faster than those without calibration, allowing for greater high-volume production;
2. Fewer defective products due to higher accuracy, resulting in lower production & material costs.
3. Increased efficiency of operation; the enhancement of machine alignment provides decreased cutting loads, increased tool longevity, and increased repeatability of machining operations.
4. Improved customer satisfaction; CNC manufacturers consistently provide high-quality products with little to no variation, resulting in improved customer loyalty.
5. Compliance with global export standards; through the processes of CNC Calibration & Precision CNC Calibration, manufacturers are able to meet the accuracy requirements of global markets
