Micro-Endmills – not the same old grind

Posted Leave a commentPosted in Equipment and Tooling

Endmilling is a mainstay of micromachining. And while micro and macro milling operations share certain similarities, there are several key differences—and surprises. One eye opener when shopping for micro-endmills is their cost—as the size goes down, the price goes up. Sometimes way up. Where a commodity 1/8” endmill might cost $6, a micro version 1/10th that […]

Thread Whirling Boosts Productivity

Posted Leave a commentPosted in Machining, Medical and Dental

Ever since British machine inventor Henry Maudslay introduced the first modern screw-cutting lathe towards the end of the 18th century, machinists have been cussing him. True, the world as we know it couldn’t exist without screw threads, but that doesn’t make cutting them any easier. Compared to other turning operations, single-point threading is slow, requiring […]

Down to the Wire – ‘Spiderman’ microwire used in medical devices

Posted Leave a commentPosted in Medical and Dental

Spiders have been doing it for millions of years: Spinning out material that’s stronger than steel, and—metaphorically at least—lighter than air. Luckily for the spider, she doesn’t have to cut tight-tolerance features on her delicate tapestry, or twist it up into precision coils and helix shapes to catch her meals. The microwire industry is spinning […]

CFRP gets tough love from microtools

Posted Leave a commentPosted in Equipment and Tooling, Machining

Carbon-fiber-reinforced plastic (CFRP) is a corrosion-resistant and lightweight material used in everything from paintball guns to Formula One racecars. The composite material has an “ultimate tensile strength” approximately four times that of steel and unrivaled strength-to-weight ratio, meaning it’s not only stronger than alternative materials, like aluminum, but you also need far less of it […]
