In today’s competitive environment, with quality and speed as important issues, precision alignment is crucial to both production and maintenance. Optical instrumentation affords the ability to align machinery with a high degree of precision.
ASNA’s 3D Metrology team utilizes an extremely accurate, portable coordinate measuring machine that enables you to build products, optimize processes, and deliver solutions by measuring quickly, simply and precisely. We help our customers resolve their everyday measurement challenges as well as their most complex problems.
Companies are saving millions of dollars by completing jobs faster, reducing downtime, eliminating costly scrap, and getting accurate, consistent, and reportable measurement data. Our 3D Metrology equipment can be run on battery power and is extremely portable.
In today’s competitive environment quality and speed are important issues. Precision alignment is crucial to both production and maintenance. Optical instrumentation affords the ability to align machinery with a high degree of precision. Providing the customer with the best information from measurements to recommendations is our primary objective. How we do this:
- Our instruments are calibrated in house regularly. Constant monitoring of our equipment allows us to insure accuracy.
- High level of precision measurement. This high degree of precision is often overkill for the types of machinery we generally work with.
- Quality Field Staff. Aside from the prerequisite qualities and education we start with in each individual, ASNA requires a lengthy training process.
- Customer has ultimate responsibility in the decision making process. ASNA is very cognizant of providing information but allowing the customer to direct the work.
In addition to precision alignment inspection, ASNA offers mechanical support to install or reposition equipment. ASNA provides equipment and personnel for machine installations, roll change outs, and corrective measures.
The first step in aligning a machine is to establish references from which all measurements are compared. For the horizontal attribute of components this reference is always level relative to earth.
For the vertical attribute, it is not quite as simple. The reference used must be accessible throughout the length of the machine. This reference is generally a representation of the machine installed in the tending aisle. It is commonly referred to as an offset machine centerline or machine baseline. The purpose of this line is to provide an accurate reference from which all other machine components can be measured for perpendicular or parallel.
In the event a machine does not have a baseline, or the existing line is in question, one can be determined. The method used to determine the machine centerline is fairly straightforward. A temporary reference must be used to initiate the inspection, which is somewhat parallel to the machine centerline. Using this reference, all individual machine components are inspected for their centerline coincidence. From this information, a line is then established which is the best possible representation of the overall machine centerline.
Baselines are typically found in the tending side aisle of most machines and are represented by either a brass plug with a prick punch mark, or a stainless steel bushing which accepts an optical target. The baselines installed by ASNA are generally of the stainless steel bushing variety. The ability to make use of the commercially available optical target allows the baseline to be more accurate, repeatable and efficient.
The next step in aligning a machine is to determine the overall alignment condition of said machine. This can be accomplished by performing a survey using the common references as described above. The resultant data can be assimilated and the more crucial elements of alignment pinpointed. Using this information a plan can be developed for each specific machine which allows for alignment to be performed over a period of several shutdowns. If time allows, alignment plans can be developed for major shutdowns.
