Defined by ASME (American Society of Mechanical Engineers) in standard Y14.5, tolerance is “the total amount a specific dimension is permitted to vary. The tolerance is the difference between the maximum and minimum limits”. Tolerance specifications and guidelines are used in all areas of manufacturing – from the tolerance standards for the components within a piece […]
The misalignment of components within an aluminum extrusion press can cause significant issues such as inconsistent die performance, uneven wear, premature failure or excessive wear of dummy blocks, and in extreme cases, damaged and/or broken stems, containers and tie rods. Misalignment in the press not only causes equipment damage and increased downtime, product issues such […]
Proper shaft alignment is essential to the operating efficiency of rotating machinery. Correctly aligned shafts ensure smooth, even power transmission from the motor to the driven components. Though there is a variety of shaft alignment tools and methods to choose from, including straightedge or feeler gauges, dial indicators, and optics – today’s laser shaft alignment […]
As with most large pieces of production equipment, precision is key for optimal operating efficiency of hydroelectric power generating units. Unfortunately, there are many factors that can effect operations and cause component damage, leading to unplanned shutdowns. Often during these shutdowns, damaged components must be disassembled, rebuilt or refurbished to OEM specifications, and then precisely […]
As a metrology services provider, we can sometimes take for granted that everyone else knows what we are talking about when we discuss our “metrology services”. In this post, we provide a brief definition overview of metrology. In future posts we will delve deeper into the many aspects of this important science and its uses […]
With many options in alignment tools and solutions available to manufacturers today, it is important to understand some basic principles of machine alignment so that you are making an informed decision when selecting the best solution for your particular machine or production line. Why is Machine Alignment So Important? Many of the costly equipment and […]
