Metrology Helps Hone Precision

Mitutoyo helps meet customer expectations in the realm of deep hole boring, where diameters are more than 20 mm. One of the specialties offered by Hone-All Precision Ltd. of Leighton Buzzard, Bedfordshire, is the machining of nickel-chromium-based super-alloy components to tight tolerances. These oxidation and corrosion-resistant materials, typified by Inconel and Hastelloy, are well-suited for service environments subject to extreme pressure and temperature, and therefore, are favorites of the petrochemical industry, however, they are very difficult to machine. Accelerated tool wear is a constant concern. This is particularly true in the case of bored-hole features that sometimes approach three meters in length and which usually have to be finished by honing to meet stringent customer specifications. Form accuracy shaped up Due to the length of a typical bore, obtaining the accuracy potential of single-point tooling is impractical, except...

Coordinating Quality at Express Engineering

Mitutoyo UK recently completed the installation of the company’s largest ever coordinating measuring machine (CMM) sold in the UK. The Crysta-Apex C CMM, with a measuring volume of 2,000 mm x 4,005 mm x 2,005 mm, enables Express Engineering to undertake the rapid, accurate inspection of large oil and gas components, including huge wellheads. Established in 1973, Express Engineering has grown from its origins as a precision engineering and tool-making company to what is now a leading global contract manufacturing group. Express Engineering supplies the global oil and gas market with a wide range of highly integrated precision machined components, kits of parts and fully assembled pressure tested products, including wellheads, christmas tree valves, manifolds, completions, tooling, flowlines and connections. During the past four decades the company has earned an enviable reputation for producing high integrity products...

Autocraft Finds a Precision Solution

Investment quickly pays off for engine remanufacturer. Autocraft_1Autocraft Drivetrain Solutions, operating from a 56,000 square-meter site near Grantham, Lincolnshire, England, is the largest independent engine remanufacturer in Europe, supplying such well-known OE manufacturers as Ford, Jaguar Land Rover, Volvo, Aston Martin, JCB and Chrysler. Engines are not the only drivetrain components processed – the company also handles transmissions and precision-machined components such as cylinder heads and blocks, plus sub-assembly of automotive parts. A new opportunity – and a challenge In common with similar engineering concerns, Autocraft absolutely depends on fast and accurate production machinery backed by an efficient inspection resource to grow the business. This reality was highlighted recently when the company was presented with a commercial prospect involving inspection of various complex components, all manufactured to a high level...

Validating Tolerances

Ultra-precise dimensional measurements critical to risk mitigation under AS9100 Rev. C. CIMG0495Gear Manufacturing, Inc. (GMI), Anaheim, CA, was founded in 1989 with a mission to manufacture high-quality custom gears and gear-related components and assemblies. Housed in 27,500-square-foot facilities, the company is equipped with the latest CNC machining centers supported by extensive engineering capabilities and leading-edge software. The company makes almost every type of precision gear configuration imaginable, which it produces in materials ranging from tool steel and titanium to cast iron, copper, all types of alloys and engineered plastics – virtually any material that can be used to cut a gear. Approximately two-thirds of GMI’s output is dedicated to the aerospace and defense industries and includes customers such as Northrop Grumman, Lockheed Martin and Boeing, as well as...

Consider a CMM for Gear Inspection

CMMs offer a capable, affordable and flexible gear inspection option. Gear inspection has long been considered a highly specialized, expensive and difficult part of the gear manufacturing process, requiring a wide variety of complicated gages, testers, dedicated CNC equipment and highly trained experts. But if you want to make good gears, you need to have all that stuff, right? probe picWell, maybe not, says John Fox, senior CMM software application engineer for Mitutoyo America Corporation. According to Fox, the time may be right to consider a coordinate measuring machine (CMM) for your gear inspection needs. “We have many customers who are using a CMM for gear measurement, production and setup,” Fox says. “Customers including Honda, Kawasaki, Hitachi, Molon Motors, etc. use the CMM to measure purchased gears. And there...

Expand Your CMM’s Capabilities

Moving from tactile and scanning systems to newer optical and laser sensor technology increases the productivity of your CMM. During the past 25 years, coordinate measuring machine (CMM) sensor technology has expanded from tactile and scanning systems to now include optical, laser and surface finish sensors, effectively expanding the CMM’s capabilities. While each CMM sensor technology has its own advantages and limitations, the expanded measuring capability provided to the CMM compels anyone with measuring requirements to consider adding additional sensor technology to a current CMM or for a new CMM purchase. OPTICAL SENSOR Optical sensors for CMMs provide non-contact measuring capability that perform [caption id="attachment_4887" align="alignright" width="300"]The process of measuring surface finish begins with selecting the planar area to be analyzed, then positioning the surface finish sensor stylus so that profile being measured (also...

CNC CMM Delivers Greater Productivity and Accuracy for Automotive Supplier

Looking for speed and accuracy for its unique processes, an automotive supplier incorporates a surface finish probe in a CMM to obtain dimensions and surface testing in a single operation. “In the remanufacturing business, you can take apart a transmission, clean it, replace all the soft parts and get it back to the customer when they need a new part,” said Gary Noel, chief operating officer and member of the board at Dynamic Manufacturing, a premier supplier of world-class OEM new and remanufactured drivetrain components for the automotive industry. “The real creativity comes from developing unique processes that can repurpose that experienced part so that it performs as good as new.” Headquartered in the Chicago suburb of Melrose Park, IL, Dynamic Manufacturing is a TS 16949, ISO 14001 and WBENC-certified woman-owned and -operated business with operations covering...

Advances in Model-Based Measurement Can Reduce CMM Programming Time

While manufacturers have applied model-based definition to product definition for some time, they have only recently applied it as a quality assurance process. With more man-hours being spent on programming work, differences in worker-created measurement programs, and inefficient programs being created due to proficiency issues, the industry has moved from 2-D drawings to 3-D annotated models. A number of factors—the increased emphasis on quality control, the growing diversity of parts and components being measured, the development of more complex global supply chains and reduced product lifecycles—have led to a considerable demand for automatic measurement programming in recent years. Automatic measurement program generation software uses 3-D CAD and product manufacturing information (PMI) to enable one-click automated generation of measurement programs. A complex program that previously would have taken five hours to complete manually can now be completed in...

Plating Tolerances Guaranteed

Incorporating a laser scanning micrometer into a quality control routine pays off for metal plating ad coating services supplier. Tawas Plating Co. & Tawas Powder Coating Inc. (Tawas City, MI) provides metal plating and coating services to automotive, aerospace and other manufacturing sectors. Almost from the beginning, Tawas experienced strong demand for its electroless nickel plating, which provides a combination of lubricity and wear-resistance, as well as dimensional control, corrosion protection and superior cosmetics. As the name suggests, electroless nickel plating does not rely on passing an electric current through a solution to form a deposit. Instead, the process depends on an auto-catalytic reaction to deposit a nickel coating on a substrate. According to Al Alexander, plant manager at Tawas Plating Co., an important advantage of the electroless process is the relative ease with which it can be...
