Extreme tools for an extreme sport
END USER: David Buchberger, (585) 208-7382, www.hispeedcorp.com. CHALLENGE: Efficiently machine lightweight components for an "extreme" racecar. SOLUTION: High-performance cutting tools, including a drill and endmill.
Good connections: Drilling Performance
The combination of rigid machine tool and strong spindle connection is ideal for cutting titanium.
Mixed signals: Industry Trends & Analysis
Manufacturing faces more uncertainty than usual in 2013, but the year ahead could be a good one.
The write stuff: Medical Manufacturing
The pros and cons of marking parts with laser, micropercussion and scribing technologies.
Trending to turning
Holding a few tenths tolerance on a piece of 60-HRC steel was once the domain of expensive grinding equipment. Today, it's no big deal.
Inside and out: Turning Performance
Similar to a multitask machine, a machine tool that combines ID and OD grinding enables producing a part in one chucking.
Meeting the workholding challenge: Turning Performance
In my August column, I described several common applications for workholding when turning, where the cutting tool is static and the workpiece spins. There are several standard workholders for turning, which were illustrated.
Apparent mass of moving machine elements
The moving elements of a machine tool have mass. Forces from the actuators cause the masses to move and accelerate. As the speed of the machine tool motion increases, the ability of the actuators to cause acceleration becomes more important.
Achieving reasonable wheel wear: General Industry Coverage
Dear Doc: I grind fine threads into hardened stainless steel with a fine-mesh aluminum-oxide wheel. The threads are 0.8mm deep in a 5mm-dia. ID. There are three threads per part. This operation just chews through the wheel, and I get only one part before I have to dress a 0.2mm depth in my 4mm-dia. wheel.
Tips for a manual milling machine
In my October column, I explained how the design of manual milling machines could be improved. This month, I share some tips for enhancing the operation of a manual mill.
Achieving flexible workholding: Turning Performance
Combustion components from Mitsubishi Power Systems had never been built outside of Japan until Savannah Machinery Works opened its doors in November 2010. We were in the unique and challenging position of having to develop every manufacturing process from scratch while maintaining a tight production schedule.
Simple activities, amazing benefits: CMM Inspection
A machine shop can become a messy place if you don't stay on top of it. If you've visited other shops, you've probably observed what I've seen over the years—a few that are spotless and well-maintained, and others that look like a cave, with little thought or care given to the work environment.
