Surface Finishing & Coating

Tungaloy Corp. is adding an economical and multifunctional chamfer cutter series to its TungQuad family, allowing multiple types of chamfering operations to be completed with only one cutter.

There is much to consider when choosing a mass-finishing system, what with operational variables from machine size and design to cutting media, compound abrasives, water volume, cycle time and more.

Abrasive stones commonly found in machine shops are fine for run-of-the-mill deburring and abrading, but absolutely not suitable for precision stoning. For that, you need a pair of carefully prepared, precision-ground flat stones.

CHALLENGE: Perform finishing operations during the machining process. SOLUTION: Tool with small, abrasive globules that are permanently mounted to flexible filaments.

When mass finishing—finishing many parts simultaneously—in a vibratory finishing system, the tendency is to use ceramic or plastic preformed cutting media, said Steven Schneider, technical sales manager at surface finishing company Kramer Industries Inc., Piscataway, N.J. Ceramic tumbling media are made with abrasive filler, much like a grinding wheel. For plastic tumbling media, plastic is mixed with abrasive filler and cast to shape. Ceramic media use aluminum oxide as filler, and plastic media use quartz or silica for cleaner results.

For our February issue's Industry Briefs department, I'm writing an article about the Deburring Application Laboratory at Matrix Design LLC. The company designs, builds and installs robotic automation systems for deburring parts, as well as machine tending and material handling.

Guyson completed a precise shot peening machine for a customer in the automotive/marine industry. This small footprint machine is equipped with a spiral separator (media shape separator) to ensure that the S-70 Mil Spec media is correct spec shape to guarantee the intensity that is required to adhere to AMS-2431/ 2E.

Softwall clean rooms from HEMCO Corp. are designed to meet ISO 5 – ISO 8 requirements and feature a flexible design that allows them to locate over and around equipment, with the option of being mobile with casters. The structural framework is of aircraft anodized aluminum with clear vinyl curtains around the unit.

​​​A year ago, a leading aerospace manufacturer approached Sandvik Coromant with a machining challenge. The operation in question was finishing deep titanium pockets, a common feature in structural aircraft components.

FTT says its in-house PVD coating is yet another example of its commitment to maintaining the latest technology in-house to provide the highest-quality, timely and efficient service to customers. These types of coatings protect the tools from heat and abrasion.

Scottie Mahl joined finishing toolmaker Osborn, Richmond, Ind., as director of marketing and product management.

When choosing an edge inspection and burr detection system, users generally try to balance accuracy and speed. The EdgeInspect system from Novacam Technologies Inc., however, acquires and analyzes edge properties and detects burrs with micrometer precision and at speeds previously unimaginable.
