The motorcycle part manufacturer featured in the cover story of Modern Machine Shop’s April issue struggled to keep up with the cyclical demand for its products—until it added the robot-tended cell visible in the cover image. Another shop featured in this issue shares its experience moving from manual to automatic pallet-switching and a third was able to reduce machine run time with an automated five-axis cell, additional examples of automation used to reduce setup time and streamline operations. Also look for stories on these topics:
How to make sure MTConnect is a good fit for your shop;
How a company made material handling safer by adding high-pressure coolant to its CNC vertical lathes;
Why a desktop 3D printer can be a valuable job shop resource;
How an EDM drilling unit improved part turnaround for an aerospace manufacturer; and
How abrasive waterjet can be used as an additive process.
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.

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.
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.
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.
