Where Micro-Laser Machining Is the Focus

A company that was once a consulting firm has become a successful micro-laser machine shop producing complex parts and features that most traditional CNC shops cannot machine.

Micromachining Turns Images of the Queen into Tiny Portraits

Engineers at the University of Sheffield Advanced Manufacturing Research Center (AMRC) used a turn/mill center to reproduce a series of tiny portraits of Queen Elizabeth II, down to only 1.4 mm wide, onto brass.

Medical

Laser Technology "Turns" into a Turning Tool

This new technology uses a laser to act as a cutting tool to "turn" parts from solid barstock. This high-speed precision turning machine is especially useful for micromachining, enabling high accuracy for small, complex parts that are often delicate and difficult to machine when implementing conventional turning processes.

Burr-Free Micro Thread Whirling

Threading is usually the last operation when machining components, which is why the process needs to be reliable and highly precise. DC Swiss has developed an internal thread whirler, which leaves micro threads burr-free, even in demanding, hard-to-machine materials.

Micromachining is About Precision

Holding tolerances on very small part features is not for the faint of heart. The skill is not only in the machining, but cleaning and inspection as well.

Laser P 400 U Five-Axis Machine Incorporates Dual Laser

GF Machining Solutions’s high-performance Laser P 400 U five-axis machine can machine small, intricate parts with a dual laser head that incorporates both a fiber nanosecond laser and a femtosecond pulsed laser.

Choosing the Right Toolsetting and Detection Technologies

Investing the time to invest in the right machines can mean the difference between a profitable operation and an ongoing headache.

Grinding

Manufacturing Efficiently at a Micron Level

Grinding very small-diameter instruments for use in medical procedures is a niche business for this micro-grinding machine manufacturer. The company makes machines that use a variety of grinding techniques to manufacture guidewires for the medical industry.

Milling Hard-to-Machine Materials on a Micro Scale

The idea of a tool that effectively controls heat with a special grade of carbide, a new coating and internal channels that deliver cooling through ports in the shank where the milling flutes begin, is worth a look.

Micro Deburring Gets Hot

“Micro deburring,” a name commonly used to describe the deburring of tiny small parts, is often considered more of an art than a science. Although this is true to some extent, deburring micro parts does not always have to require hand manicuring parts with a scalpel under 10× to 20× magnification.

Machining Center for Small Workpieces

Here’s a different approach to a micromachining center--a machining strategy developed around interpolation, allowing machining operations to benefit from the dynamic control of the worktable while reducing the number of tools needed.

Purpose Built Micromachining Center

In metalworking, it is rare to find new approaches to well-established technologies; usually new developments are major or minor upgrades to known elements. This micromachining center is rewriting the rulebook.
