When to Mill Keeps Changing
Technology improvements steadily expand the range of tool and die parts that justify high speed machining.
Tool Certainty
For GKN Aerospace to overcome tool-related variations on its largest milling machines, it had to confront error sources that go unnoticed in many shops.
Selecting A VMC: Things To Consider
A three-, four- or five-axis vertical machining cneter can run the gamut of capability and cost. Assessing your application requirements now and in the future can make for a much wiser machining cneter purchase.
Complementary Technologies Make MQL More Accessible
An add-on system for minimum quantity lubrication (MQL) combines an external pump with repeatable control over nozzle position.
Easy Does It
This shop specializing in small-scale parts says successfully machining tiny features into tiny workpieces is less about technology and more about technique.
The Case For Constant Velocity
Constant Velocity Technology uses high speed computer hardware and creative algorithms to enable machine tools to achieve fast, consistent feed rates across complicated 3D surfaces.
Using Twin-Table Machines To Maximize Spindle Uptime
By integrating twin-table, bridge-style machining centers, this shop virtually eliminates spindle downtime during job chang-eovers. An operator can safely set up a new job on a table located outside the machine's workzone while the machine mills a w...
Get Better Before You Get Bigger
Rather than making a major new machine tool purchase just yet, this shop is finding additional capacity on the equipment it already has. What once was a vertical machining center will become a flexible automated production center for unattended mach...
High Speed Machining ... Without The Speed
Axial chip thinning is often associated with high speed machining, but this shop uses the same effect to increase metal removal rate with a standard-size end mill run on a moderate-speed machine.
Don’t Forget The Drawbar
The force that holds the toolholder in the machining center's spindle can weaken over time. If you haven't checked drawbar force in a while, this may be the weak link in your process.
