Product Slideshow: Turning

This month’s product spotlight highlights turning equipment—lathes, turning centers, mill-turn machines and even a CNC specifically designed for turning. Many of the turning machines covered have features designed to make them more flexible. For example, the EcoTurn 650 turning center from DMG MORI can be equipped with an optional C axis for turn-mill machining. Meanwhile, the Hwacheon VT-1150 vertical lathe has a geared drive system that enables high-torque turning at low speeds as well as high-speed turning.

Video: Compensating for a Bad Center Hole

A center hole that is drilled even slightly off-center can lead to a non-concentric workpiece. If no adjustments are made and the runout is too much, that workpiece ultimately ends up as scrap. While a bad center hole may be only an occasional problem, it can be fairly simple to correct with the use of a compensating live center.

The video above from Riten Industries demonstrates how its Adjusta-Point live center is able to offset a shaft’s deviation by means of external adjusting screws. The adjustment process is similar to indicating a part using a four-jaw chuck, and it takes only a few minutes to bring the shaft back within acceptable grinding standards.

March 2015 Gear Production Digital Edition Available

The March issue of Gear Production (a quarterly supplement to Modern Machine Shop) contains two examples of shops that were able to not only embrace, but optimize equipment and software to streamline production. Click the cover image above to access the digital edition and read about:

  • How a shop serving the mining industry eliminated multiple machining steps on large gears with a 6-meter profile grinder.
  • A shop that optimized its separate production paths for “cut-teeth-only” and “make-complete” gear jobs via scheduling and resource allocation software.

This issue also includes an overview of waterjet machining for gear production and new product coverage.

Product Slideshow: Machining Centers

Each month Modern Machine Shop focuses on a specific type or category of manufacturing equipment in the Modern Equipment Review Spotlight section. The March 2015 issue highlights machining centers ranging from compact five-axis VMCs to large HMCs designed to accommodate aerospace parts. Click the photo above for a slideshow featuring these machines and more, and check the print or digital edition of the magazine for the equipment spotlight in each issue.

Are You Using the Right High-Pressure Coolant?

High-pressure coolant operating at 1,000 psi and higher can significantly reduce tool wear, enable higher cutting speeds and provide other benefits for manufacturers working with tough materials. However, using the wrong coolant in a high-pressure system can cause foaming and hinder potential gains, as LB Pipe & Coupling (Mongolia, Texas) discovered.

LB Pipe began experiencing foaming problems during the initial startup of a new robot-tended cell, halting production before it had even started. After trying a number of modifications to the coolant lines, pump, tank, tooling and nozzle configurations, the ultimate solution turned out to be the simplest: change the coolant.
