Please welcome Matt Smith to the Next Generation Tooling Team! We are very pleased to announce that Matt Smith has joined our team.
PMC-Colinet has a long history in the pipe and tube market, having started in 1912 and introduced the world’s first carbide-tooled pipe threading machine in 1958. Today, the company is established as a primary supplier of machines to the OCTG sector. Its customers include integrated steel mills that sell finished pipe and couplings to the oil and gas industries, specifically using the company’s machines for threading products for downhole drilling applications. PMC-Colinet also supplies cutting tools, consumable tooling, aftermarket parts and field service to the industry. Recently, PMC-Colinet did an assessment on one very challenging job, namely, cutting keyways into large sections on a high-precision cutting tool head made of Nitralloy. For many years, the production had involved the use of a shaper to produce the keyway in the bore of the die head. Typically, the bore ranged from 6” to 13” in diameter and more than 12’ in length. These keyways have extremely tight tolerances, with location at +/- 0.0005”, width at +/- 0.001” and depth to +/- 0.0025”. One style of cut is a 3-step keyway that does not run all the way through the bore, stopping at a window that is milled from the outside diameter. This situation prevented the PMC machining department from using a ram EDM to produce the keyway. The only options previously used were to rough the keyway on an old shaping machine, then send it out for ram EDM. This process required 50 hours on the shaper, plus approximately a week for the ram EDM. Another option was to do the job entirely on the shaping machine. Roughing the keyway had to be much more precise and usually required about 61 hours. Plus, an additional 145 hours were required to finish the part, normally. These times included 10-12 hours for set-up.
One competitor brought a standard 40 taper tool, while Heimatec presented a larger, heavier 50 taper unit.
A week later, Preben Hansen, Heimatec’s president, supplied a drawing for the proposed custom product. PMC engineering reviewed both the standard and custom designs and awarded the project to Heimatec. The angle head supplied was designed to perform a wide variety of cutting tasks on the various end products produced by PMC. On the keyway in a bore 6” in diameter and 12” in length, using the Heimatec 90º head, PMC spent 6 hours in setup, 3 for roughing and 3 for finishing, plus 12 to 16 hours of actual cutting time. This represented a total savings of 184 hours on a single part. Though the head appeared too slender to remain rigid during the entire cutting cycle, according to PMC sources, the performance was deemed very successful. Heimatec’s head design for this custom radial drilling and milling head features an adjustable tool stop, 3 support pins for stabilizing the tool, CAT 50 taper style, 360º indexable pivot on the angle head and inclined tooth gear design for maximum rigidity. During the project, Preben Hansen from Heimatec supervised the installation. After the stop block attachment and grinding of the supports pins for the head were accomplished in just one day, the head was mounted and several experimental cuts were performed. Hansen spent time with Rick Kokish as well as CNC programmer Barry Spence at PMC, discussing various options for programming the head on the Monarch VMC. The very next morning, the setup was performed and an actual keyway was roughed. Results ongoing have continued to satisfy all requirements, according to PMC sources.

Masa Tool, Inc. is a company founded with the mission of bringing micromachining solutions to industry. The name "Microconic" comes from the sophisticated grinding techniques that were developed for their collets.
These techniques provide the advantages of extreme accuracy, high gripping force, and high tolerance for workpiece size differentials. Each finger of the collet has a separate conical surface that acts to apply the gripping force with superb accuracy. Click on their logo to lear more! What kind of burr can the sPINner remove? We are often asked, “What kind of burr will the sPINner remove?” The standard answer is “a light burr”. This answer leaves a lot of room for interpretation. What is a light burr to some will be a heavy burr to others. The rule of “Thumb”: In order to form an initial evaluation if the sPINner will work on a particular part try the rule of “thumb”. As a general rule, if you can take a fingernail and remove the burr, the part has a good chance of testing well in the sPINner. Burrs heavier than this may tend to roll and flatten, but not be removed during the process. A quick lesson on burrs: Light Burrs
A lighter burr can be loosely defined as a burr with a thin thickness at root (B1). As the amount of material holding the burr to the parent metal increases, a more aggressive deburring action is required to remove the burr. Using this definition it is possible to have burrs that are tall, yet are “lighter” by our definition because the thickness at the root is small. Burrs of this type are good candidates for the sPINner. Short Heavy Burrs An example of short, yet heavy burrs are the ridges created from drilling. When a drill breaks through a part a ridge is pushed up around the hole on the side where the drill breaks through. While this ridge can be short in burr height (H0), the thickness at burr root is wide. Often this material is more a part of the parent metal than the burr. These burrs will not be good candidates for the sPINner as a very aggressive and abrasive action that has a high stock removal rate is required to remove these burrs. Brittle Materials Another factor to weigh in this process is the material itself. More brittle materials will tend to have the burr break away from the part (parent metal) making the sPINner a good option. Softer Materials Softer or more malleable material will tend to have the burr roll and flatten. Softer materials need to have a thinner thickness at root to be good candidates for the sPINner. |
