Watch Cutting Tool Engineering's special three-part video report that follows along as Rush Machinery in Rushville, N.Y., and Jeffrey Badger, Ph.D., a.k.a. the Grinding Doc, collaborate to establish scientific truing parameters. The report encompasses episodes 83, 84 and 85 of CTE's Grinding Doc video series.
For the 10th episode of The CNC Chef, Bob Warfield of the CNCCookbook discusses the challenges presented when drilling deep holes. Among them: clearing the chips, getting coolant down deep, and holding tolerances on position, diameter and surface finish. As Warfield observes in this episode, "all of this means we need to use some special strategies whenever we have to go more than 5 diameters deep, and that's what this video is all about."
Thanks to a collaboration between Dr. Jeffrey Badger and Rush Machinery in Rushville, N.Y., shops now have some practical guidelines when it comes to truing parameters. Badger shares some of this new-found advice in 85th episode of Cutting Tool Engineering's Grinding Doc video series.
PFERD Inc.'s CC-GRIND®-SOLID for controlled rough grinding applications integrates a fibreglass backer and a high-performance coated abrasive that is said to be 40 percent more productive than reinforced grinding wheels. To illustrate the point, PFERD filmed a demonstration comparing the CC-GRIND-SOLID to one of its own conventional rough grinding wheels and that of a competitor.
In the ninth episode of the CNC Chef, Bob Warfield of the CNCCookbook covers the role of coolant in CNC machining and offers some tips for using coolant more effectively.
For the 84th episode of the CTE Grinding Doc video series, Dr. Jeffrey Badger offers some preliminary results and observations from his work with Rush Machinery to establish scientific truing parameters.
Understanding high-speed machining, or HSM as it's abbreviated, can be difficult for the simple reason it's defined in so many different ways, according to Bob Warfield of the CNCCookbook. As he explains in the eighth episode of The CNC Chef video series, HSM means a lot of things to different folks, but it's best to think of it as a coordinated set of techniques designed to increase machining productivity.
For the 83rd episode of Cutting Tool Engineering's Grinding Doc video series, Dr. Jeffrey Badger visits with Rush Machinery in Rushville, N.Y., to begin a three-part series devoted to establishing scientific truing parameters. With the help of Rush Machinery President Bill Freese, Badger conducts a series of truing tests using the Grinding Doc Grindometer.
For the 82nd episode of Cutting Tool Engineering's Grinding Doc video series, Dr. Jeffrey Badger explains why using the Barkhausen Noise Signal to assess grinding burn is a tricky business.
Wanner Engineering Inc. and ChipBlaster Inc. provide some insight into the effectiveness of high-pressure coolant to prolong tool life and eliminate heat damage. Cutting Tool Engineering produced this report based on informational videos submitted by ChipBlaster and Wanner Engineering.
Contrary to some politically motivated hyperbole, manufacturing is alive and well in the United States. While it is true there are far fewer manufacturing jobs in America, there are multiple reasons for that—it's not solely about manufacturers seeking cheaper labor overseas.
Dr. Jeffrey Badger examines why many shops experience pain when cylindrical grinding a face, or shoulder, in the 81st episode of the Ask the Grinding Doc video series, which is produced in collaboration with Cutting Tool Engineering.
Bob Warfield from CNCCookbook discusses some toolpath tips to help you get the most from your CAM software in the sixth episode of The CNC Chef, a video series produced in collaboration with Cutting Tool Engineering.
Renishaw plc recently posted a brief video to YouTube that offers an overview of the company's new SPRINT system with SupaScan. The system is designed for simple integration into machine tool applications requiring exceptionally fast workpiece set-up, and where overall cycle time is critical.
Bob Warfield of the CNCCookbook walks through the benefits of turret versus gang tooling for CNC lathes in the fifth episode of The CNC Chef, a video series presented by Cutting Tool Engineering and CNCCookbook. Warfield offers some insight for those trying to decide which is best for a particular job.
Using a Norton SG grit wheel, a shop turned to the Grinding Doc to find out why they suddenly lose form on the 7th or 8th part. To prevent bad parts, the shop dresses the wheel after every 5th part.
CoroMill 745 multi-edge cutter with high feed capability is in this demonstration used for face milling in cast iron. The 25 degree entering angle of this cutter version allows for high feed milling strategies to be utilized. The concept has a double-sided multi-edge design, making it a cost-efficient solution that delivers high productivity.
A shop sometimes experiences burn when using a CBN wheel to cylindrically plunge-grind a part. Slowing down doesn't help. Dr. Jeffrey Badger, who writes the Ask the Grinding Doc column for Cutting Tool Engineering magazine, offers a remedy.
The new Spade Drills from YG-1 are intended for a wide range of applications and raw materials such as steels, stainless steel, cast irons and so on. The indexable drill offer a wide range of diameters: from 9.5mm to 114.3mm. This video demonstration by YG-1 shows normal and slow motion cutting action of the Spade Drill HSS Insert (Ø20.0 / 8xD holder).
