New Honing Options For Hypereutectic Aluminum Cylinder Bores
Hypereutectic aluminum is saturated with silicon particles that must be exposed during honing. A two-stage process first hones a cylinder’s wall to a mirror-like finish and then relieves aluminum around the silicon particles.

How to Hone an Atypical Aluminum Alloy
Hypereutectic aluminum used for engine blocks contains silicon particles that must be exposed during cylinder honing. This can be done using a cushioning, elastomer honing tool that allows individual abrasive particles to “bounce” over the silicon particles.

Hydraulic Workholding Devices Allow Total-Perimeter Machining
Having access to the entire perimeter of a part minimizes set ups because shops can machine five sides of the part in one fixturing. This enables shops to reduce the total number of manufacturing operations, the number of times parts must be handled, the potential for part damage due to excessive handling and the o

Turning Is Optional
The part requires only milling and drilling, but it is still run on a lathe. Except for the cutoff tool, all of the turret positions on this lathe hold rotating tools. In other words, turning is not essential for using a lathe effectively. This application illustrates the productive possibilities of a modern turn-mill machine.

Coolant Filtering System Delivers A Clutch Performance
Sludge and grit in contaminated coolant can build up in the moving parts of machine tools and increase component wear, adversely impacting productivity. Faced with rising maintenance costs and increased machine downtime, this manufacturer of automotive components found a solution in a coolant cleaning system developed by Mayfran International.

Lose The Peaks, Leave The Valleys
Plateau honing improves cylinder wall surface finish by gently removing tiny peaks of torn or folded material. Ball-style honing tools are commonly used to produce this desirable finish.

Machine Tools Used As Dedicated Equipment…For A Little While
Two keys to this shop’s success are versatility and speed. It uses flexible machining centers, rather than dedicated equipment, and constantly reconfigures them into new cells for new jobs. The speed at which it can do this, in addition to in-house tombstone manufacturing capability, provides the nimbleness to quickly respond to its customers’ needs.

When Four Spindles Make Sense
For the right applications, four-spindle CNC chuckers offer practically zero delay for part loading. That’s because two spindles can be loaded while the other two are making chips.

Becoming More Than The Mom & Pop Race Shop
Carney Custom Machining started with a VMC and customer base largely comprised of drag racers. Now the shop is vying to win work from other sources, and CNC turning is a big part of that strategy.
