The Lean Selection cam is a flexible machine concept for machining camshafts in all batch sizes.
Triumph is a well-known name among motorcycle enthusiasts. The reliability and lasting value of the bikes is due to their high-quality production. Triumph uses the Lean Selection cam high-speed grinding machine from JUNKER to grind its camshafts.
"The models in the Modern Classics line are currently our most popular motorcycles-for example the Thruxton or Bonneville," said Jack Sellers, Production Engineer at Triumph Motorcycles Ltd. in England. "The Modern Classics line is made up of new motorcycles with current technology in a timeless design. These classic bikes make for reliable companions, both on the roads where adventure lies around every corner and on leisurely rides where the rider can enjoy the synthesis between man and machine."
What is more, as of the 2019 season, Triumph Motorcycles is now the exclusive engine supplier to the FIM Moto2 races, bringing its many years of experience in high-end engine building to the table.
Meeting Highest Quality Requirements
The high-quality finish of the camshafts for the engine plays a key role. To achieve this, Triumph uses four Lean Selection cam machines from JUNKER. In addition to its headquarters in England, Triumph also has production sites in Chonburi, Thailand. The motorcycle manufacturer produces around 56,000 bikes each year at both locations and has had a positive experience with the Lean Selection cam for high-speed grinding.
Sellers said, "It is very important to us that the machines are reliable. The camshaft quality must always meet the high requirements that Triumph expects of its components. Thanks to the tried and tested Lean Selection cam, we can maintain a high level of quality. This can also be achieved in three-shift operations, seven days a week."
The Lean Selection cam from JUNKER is designed for companies that require ?exible production. The available grinding operations include cylindrical and non-cylindrical grinding. Cylindrical, convex, concave, polygonal or elliptical workpiece geometries can be ground, with chamfers or radii if needed. "It is particularly important for the motorcycle manufacturer that cams and bearings can be ground on the same machine in a single clamping set-up," said a spokesperson.
Quick Changeover for New Workpieces
Triumph has stringent requirements when it comes to ?exible production. Technical improvements to components mean that the grinding process needs to be constantly readjusted. The Lean Selection cam makes it quick and easy to produce this wide range of high-quality parts. Small series require rapid machine changeover, which is where the machine's easy operation comes into play. "Our set-up engineers who work with the Lean Selection cam can change over the workpiece and associated program," said Sellers.
He went on to mention an example of rapid support for unusual requirements: "We grind very small concave radii on the camshafts. Due to a ?ange positioned in the center of the workpiece, we had to come up with a solution to ensure that the spindle housing did not collide with the workpiece. JUNKER supplied an integrated turning station-a clever, custom-made solution."
JUNKER assists with the integration of new machines. Triumph employees completed training for programmers so that the new machines would be up and running right away. Sellers said, "The trainers from JUNKER were highly motivated, capable and explained everything. This meant that we had a good understanding of the machines right away. We are also highly satisfied with the service in England and Thailand. If we have any inquiries, JUNKER is quick to respond and suggest solutions."
