HIGH SPEED MACHINING

Micro Milling At 1/2 Million RPM

Researchers aim to develop a spindle that accounts for the differences between macro and micro machining.

Cutting Tools

Understanding Surface Location Error

Change your speed by a few hundred rpm and the tool’s effective cutting radius may change.

Five-Axis

Sweet, Sweet Spot

For this aerospace job shop, harmonizing key aspects of each high speed machining process creates a "sweet spot" where productivity jumps. Harmonizing other key aspects of shop operations also creates a "sweet spot" that helps the company capitalize on this jump in machining productivity.

Automation's Extended Reach

The experience of a Windsor mold shop offers an object lesson in machine shop automation. In an interconnected process, automating one aspect of the process offered benefits beyond what the initial planning had led the shop to expect.

Six Advantages Of Horizontal High Speed Machining

Large monolithic aircraft parts may be machined more productively one at a time instead of three at once.

The Overhang Effect

The length by which the tool extends from the toolholder is a variable that can be used to 'tune' the machining process. Contrary to what you may expect, increasing the tool's L:D ratio may reduce chatter and result in more productive milling.

High Speed Machining, Italian Style

One of the highlights of BI-MU, Italy's recent biennial machine tool show, was the number of innovative machine tools (and related technology) focusing on high speed machining.

High Speed Electric Spindle Rigidity Helps Company Meet Quality Challenges

High spindle speed is a necessity for this engraving company, but the rigidity of the spindle is another major factor in achieving quality engraved numbers, letters, logos or other characters.

Increasing Torque For A High Speed Spindle

Torque, not power, is the most important characteristic for determining the cutting performance of a spindle. Increasing spindle torque for a high speed machining center ultimately affects not only the choice of spindle but also the design of the machine.

Automating The Mold Shop

This shop produces dies and molds around the clock 7 days a week, yet most of the time no one is there.
