Redefining Multi-Spindle Machining
The premise of this mega-multi-spindle machine design is to provide a dedicated spindle for every tool required to machine a part. It proves most effective for applications in which tool change takes longer than the cutting operations.

Light-Activated Glue Holds And Releases Workpieces In A Flash
This alternative workholding method uses adhesive cured by UV light to "clamp" complex-shaped parts to a fixture. After machining, a quick laser beam "unclamps" the part by destroying the adhesive.

A Simple Way To Implement A Qualified Tooling System
Shops often use a DNC system simply to transfer part program files to machine tools. While this certainly has its advantages, few shops use DNC in more advanced ways, such as a means of integrating a qualified (preset) tooling system to monitor tool life and speed setups.

Using Hard Turning To Reduce Grinding Time
A machine tool builder found that by hard turning its lathe spindle shafts extremely close to net shape, it could cut grinding time in half.

Leveraging Little Holes To Lure Additional Work
Not many contract shops can drill a 0.001-inch hole. This one can, and it uses its micro-hole-making capabilities to attract more 'traditional' machining work from its customers.

An Indexable Insert
The solid end mill is a machine shop staple. Its positive cutting edge removes metal by slicing through the material, rather than by scraping.

Korea On The Move
A number of the Korean machine tool manufacturers that recently attended SIMTOS, Korea's biennial machine tool show, say they are reaping the benefits of a healthy automotive industry and the booming Chinese market. In fact, the show's organizer, Korean Machine Tool Manufacturer's Association (KOMMA), expects machine tool production in Korea to increase by 10 percent this year, fueled by an export market it anticipates will remain strong.
