Revolutionizing gear inspection

Published

on

Gleason presened its latest solutions for gear metrology applications: 300GMSL Gear Metrology System with full flank form laser scanning for prototyping and R&D work as well as GRSL Double Flank Gear Rolling System with integrated laser technology for high volume, 100% in-process inspection of gears.

Gleason Corporation presented powerful analysis systems that revolutionize gear inspection with its 300GMSL Multi-Sensor Gear Inspection System and the GRSL Gear Rolling System with integrated Laser Scanning at the Control Show in Stuttgart/Germany on May 07-10, 2019.

The versatile platform of Gleason’s 300GMSL Gear Metrology System provides the classic tactile probing methods for inspecting conventional gear characteristics on spur and helical cylindrical gears as well as straight, spiral and hypoid bevel gears with a diameter of up to 300 mm. In addition, the new inspection system allows non-contact laser sensor scanning of tooth flanks to support gear development. Complete topography data can be recorded far more rapidly than with conventional tactile probing, with comparable results – depending on the tooth flank surface.

The integration of laser scanning and associated 3D graphics with CAD interface considerably expand both the functionality and the range of applications for this machine platform. The new option makes the 300GMSL the ideal solution for research and development applications, for both prototype and production parts or when reverse engineering is required. Further options include surface finish measurement or Barkhausen noise analysis to inspect grinding burn.

The 300GMSL Inspection System is also an ideal fit for rapid measurement of topography in regular production operation and satisfies the increasingly stringent requirements on gear inspection. Compliant, soft materials (such as plastic gears, for example) can be inspected without sustaining damage. Multiple technologies combined in one single machine platform reduce operating costs, annual maintenance, certification costs and space requirements.

The GRSL Gear Rolling System with Laser allows in-process gear inspection and sets a new standard for throughput where high-speed, high-volume testing is required. It provides both, double flank roll testing as well as analytical index and involute measurement on all teeth in a matter of seconds. 

This new technology is available in manual, semi-automatic or fully automatic configuration depending on the needs of the customer. The index and involute measurements are analyzed using Gleason GAMA Gear Automated Measurement and Analysis Software which allows operators to see common charting between a GMS Analytical Inspection Machine and the GRSL Gear Rolling System. With GAMA, over fifty analysis packages are available for customers with all major industry standards such as AGMA, DIN, ISO, etc., along with customer specific analysis requirements developed specifically for the GAMA Platform.

This patent pending design is unparalleled in inspection speed and capability. It measures external cylindrical gears up to 250 mm in diameter in a range of .4 to 7.2 module. The double monitor option provides a simple view of ongoing trends in the high-speed inspection environment where one monitor can display results of several hundred parts inspected over time while the other can show real time results of the gear being inspected.

All GMSL and GRSL systems, like our entire GMS line of products, are able to export data using Gleason’s Closed Loop capability function.  The Closed Loop functionality has been employed for many years in bevel gear production and has been adapted to the manufacture of cylindrical gears by Gleason for several years now.  Closed Loop enables a metrology system to send results directly to a Gleason production machine such as a power skiving, grinding or honing machine, to directly transmit data for auto-correction at the machine tool without the need for human intervention.

Inspection systems presented is accompanied by high-precision LeCount Expanding Mandrels, specifically developed for metrology applications, to boost precision and measuring efficiency. Gleason also showcased its range of master gears for inspection and checking applications to provide a complete, worry-free metrology system from one source.

By

A family member of the Gleason Corporation, Gleason Works India, turns 25 on November 6th, 2021. 

Gleason Works India commemorates its 25th year of operations on November 6th, 2021. To recognize this important milestone, Gleason Works India will hold a celebration for current and former employees on November 8th, 2021. Long-time employees who have been with Gleason Works India for more than 20 years will be honored for their service to the company during this special event.

Gleason Works India Pvt. Ltd. was founded on April 01, 1996, as a wholly-owned subsidiary to provide sales, service and local manufacturing capabilities within the Indian market.  The start of operations was dedicated formally on November 06, 1996 by the former President of Gleason Corporation, Mr. James S. Gleason. Over the years, Gleason Work India’s product program has been extended to include a wide array of bevel and cylindrical gear tooling products, gear machine production, as well as machine remanufacturing activities. 

A significant milestone was achieved in 2017 with the completion and inauguration of a modern, 65,000 square foot factory, including activities for tool manufacturing, services and machine assembly. With its own solar panel roof installation, the plant produces more than 70% of its daily energy requirements, thus helping to achieve LEED certification in 2018. The new facility puts design, manufacturing and testing under one roof, giving Gleason India a self-sufficient operation to help meet domestic and global demand for Gleason products such as the 200SVP Gear Shaving Machine and customer-specific tooling solutions.  

Commenting on this milestone, John J. Perrotti, President and Chief Executive Officer of Gleason Corporation, said “Gleason Works India is today considered one of India’s most modern and productive sources for a wide array of gear manufacturing solutions. Congratulations to the Gleason Works India team for this great achievement and we look forward to further growth and success together.”

Celebrating 125 Years of Gear Technology in Munich

Published

By

April 3, 2021 marks the 125th Anniversary of Gleason-Hurth Tooling GmbH, and a proud legacy of innovation dating back to when mechanic and tinkerer Carl Hurth founded his first workshop on Munich’s Viktualienmarkt. Today, Gleason-Hurth Tooling GmbH is an important part of global leader Gleason Corporation, producing advanced workholding and precision tools for the world’s gear manufacturing industries.

Gleason-Hurth Tooling GmbH, Munich, Germany, celebrated its 125th Anniversary on April 3, 2021, a significant milestone in its rise from a small workshop on Munich’s Viktualienmarkt, to one of the world’s leading innovators in the production of high-precision workholding and tools for the global gear manufacturing industry. Products today include some of the most advanced and productive shaving cutters, chamfering and deburring tools, master gears and setting masters, honing and grinding tools, as well as diamond-plated dressing tools for a wide range of applications.

Most recently, the company’s plant facilities on Moosacher Strasse in Munich Milbertshofen have been completely renovated with state-of-the-art equipment and extremely efficient workflow and quality processes. In addition to the ultra-modern, digitized production, the newly designed office environment offers employees all the amenities and benefits of a creative and flexible working environment.

Company officials credit much of Gleason-Hurth Tooling GmbH’s continued success to its workforce of skilled and dedicated employees. The company continues to train its own apprentices to hand down critical skills and methodologies to the next generation of coworkers. Indeed, a large part of the company’s workforce today completed their apprenticeships at the Gleason-Hurth Tooling GmbH plant. The facility also serves as a training center for the global Gleason Academy with an extensive program of training, seminars and webinars.

Today, Gleason-Hurth Tooling GmbH is poised for significant future growth, and well positioned to meet fast-growing demand for innovative new drive concepts for electric vehicles, and other emerging products using increasingly complex, high quality gears.

Historical Background

In 1896, mechanic and tinkerer Carl Hurth founds his first workshop in a backyard at Frauenstraße 19 on Munich’s Viktualienmarkt. The development of his own gear hobbing machine in 1904 marks the beginning of his specialization in gear manufacturing. The business expands to such an extent that in 1911 the Carl Hurth Maschinen- und Zahnradfabrik is built at Holzstrasse 19 in the Glockenbach district of Munich.

In the 1920s, the son of the company founder, Hans Hurth, takes up the manufacture of motorcycle gearboxes. The company now employs 800 people. In 1935, cylindrical gear shaving is added to the manufacturing program. In the following decades more than 100,000 shaving cutters are produced and shipped globally.

From 1958 on, machine tool building activities continue in Moosacher Strasse in Munich Milbertshofen. Six years later the plunge shaving process is developed, which – to this day – is one of the most widely used processes for gear finishing. Supported by the rapid economic growth of the time, employment in Munich increases to over 3,000 people in 1969. In 1983, the two Munich plants in Moosacher Strasse are merged to bundle activities related to gear technology. Hurth achieves world fame with transmissions for tractors, marine applications and rail traffic, including those for Munich’s subway and commuter trains. With the introduction of “Power Honing” in 1993, Hurth again heralds a trend-setting development in hard finishing of cylindrical gears.

In 1995, the Machines and Tools division is acquired by Gleason Corporation. Gleason leverages the long-standing relationships of both companies to drive the group’s expansion in the global marketplace. The company now operates as Gleason-Hurth Machinery and Tools. Within the Gleason group, the Munich site becomes the competence center for fine finishing of cylindrical gears. The product range of gear manufacturing machines includes chamfering, shaving, honing and threaded wheel grinding machines as well as corresponding automation, workholding and tools. With the reorganization of Gleason’s European Competence Centers in 2015, machine building is relocated to the Gleason-Pfauter facility in Ludwigsburg. The Munich site now concentrates on workholding systems and gear manufacturing tools and operates as Gleason-Hurth Tooling GmbH.

While the company will celebrate its 125th anniversary on April 3, 2021, the planned open house and company celebration will be postponed to 2022 due to the pandemic. Check Gleason’s social media channels and website for more information on the planned events.
