Consider these factors when selecting the type of magnetic chuckImposed LimitThe most obvious limit to using magnetic workholding is that some materials, such as ceramics and plastics, as well as some metals such as stainless steel, aluminum or bronze, cannot be held by a magnet. […]
This component includes both the toolholders and the cutting tools where certain standards must be taken into account in order to be successful in HSM applications. The specified standards pertain to balance, concentricity and spindle connections. […]
In order to achieve the quality and accuracy required in micro-milling while meeting economic constraints, the entire manufacturing chain must be optimized and synchronized. Vendors of CNC machines, cutting tools, holders, clamping tools and quality control equipment are all required to provide the right solution at a competitive cost. […]
The need to maximize machine utilization and capability is a constantly increasing one. Modern machine tools with spindle speeds of 60,000 to 80,000 rpm represent real opportunity to achieve those goals, and are a big part of the ability to achieve high-speed machining (HSM). […]
Everyone intuitively understands that milling machines, holders and tools are difficult to scale down to the microscopic dimensions and extreme accuracy needed for micro-milling. At first glance, software might seem to be an easier fit. […]
Proper application of speed and feed for the material hardness are critical factors for good tool life when hard milling with ceramic inserts. Unfortunately, depth- and width-of-cut, as well as cutter lead angle, are commonly overlooked. A basic understanding of how these factors influence tool life can make a huge difference in metal removal rates. [...]
This component refers to the programmers and their available options. Clearly, the software (CAD/CAM) available to the user dictates many of the programming variables from which they can choose. […]
Workpiece sizes are decreasing, while part versions increase. The miniaturization in the manufacturing world demands changes in the manufacturing process. These increased demands require rethinking in order to work more efficiently with smaller tool diameters, […]
The two major enemies of the spindle are: (1) heat and (2) contaminants (namely, chips and coolant invading the bearing system). Find out what design features are included (or available as options) that protect the spindle. Historically, […]
In the world of polishing, current trends are mirroring industry trends: overseas competition, shorter leadtimes and high-speed machining technology decreasing the need for handwork and finishing. Below are five trends and opportunities in this market. […]
