SERVICES THAT MAKE A DIFFERENCE.
FROM IDEA TO FINISHED MODULE.
What excites us most about our challenging work is that no two projects or orders are alike. This is why we consistently maintain the same level of passion when implementing custom solutions that accurately meet our clients’ specific requirements. In the development, production, procurement, and assembly of mechanical and electromechanical components and modules, we concentrate on innovative production processes and certified quality. This is never an end, but rather an effort to do everything possible to ensure that our clients' products, which come from a wide array of industries, function perfectly.
OUR EXPERTISE LIES IN UNDERSTANDING.
We are proud to have collaborated with numerous large industries for many years, as evidenced by our extensive collection of certifications and safety approvals. However, it is not only the industry that matters; what truly counts is our shared commitment to delivering the highest quality and innovative functionality. We seek to be a knowledgeable partner for our clients, fully comprehending not only the significance of specific components but also the entire product manufacturing process. In most cases, we consistently achieve this objective.
HOW CAN WE HELP YOU?
Development.
Everything, from planning or modifying individual components to conducting feasibility studies and developing production-ready modules and entire systems, comes from one source.
Electronics.
Complete design flow, including creation of specifications, a PCB layout and corresponding firmware, and delivery of fully assembled boards.
CAD/CAM.
System performance from development, design, calculation, costing, programming, and simulation, including the end-to-end documented process.
Supply Chain Management.
Central supply of modules or complete units and coordination of all interfaces with suppliers, production processes, and process partners.
Assembly.
Coordinated procurement of third-party parts and modules, incoming goods inspection and functional testing with documentation, including logistics and digital data processing.
FINER POINTS OF PRODUCTION.
Our range of services includes many processes and solutions that go far beyond the actual craft of precision mechanics, e.g., engineering, and logistics. However, we are also experts in all the relevant machining techniques and in the professional use of the latest hardware and software. The following overview provides all the details.
MILLING.
Our milling shop, which boasts over 30 machines—seven with pallet stations and three automated with robots—is situated across three halls. Our machine fleet includes travelling-column machines with a movement path of up to 3,600 mm, horizontal machining centres with a movement path of 600 mm, and 5-axis centres with a movement path of 500–1,250 mm. Almost all our machines come equipped with high-pressure systems for high-performance machining, and some also feature an integrated turning function. The department is also outfitted with various presetting devices for preparing approximately 10,000 tools. With this cumulative capacity, we can mill complex parts with tolerances up to IT 6, meeting the most precise requirements in terms of shape and position.
TURNING.
Half of our lathes, all situated in Hall 5, are turn-mill centres. They have a machining range of 1–600 mm in diameter and up to 1,500 mm in turning length. Steady rests are utilized on various machines for the manufacture of long, slender parts. In our milling shop, we primarily employ high-pressure systems to ensure cost-efficient production through deep-hole drilling and internal roller burnishing technology. Our state-of-the-art machinery enables us to turn complex parts with tolerances of up to IT 5, adhering to the highest standards for shape and positional accuracy.
GEARING.
We employ modern turn-mill centres to produce gears and components with external gearing accurately and efficiently in a single process. Our services include manufacturing spur gears and gear shafts according to DIN 867 and fabricating splines according to DIN 5480. We can process modules ranging from 1 to 4 mm and manufacture gears with a diameter of up to 150 mm. We achieve a quality level of up to 8, adhering to the standards of DIN 3961 and DIN 5480-15. For internal gearings or smoothed surfaces, we collaborate with specialised premium suppliers from the gear manufacturing industry to ensure optimal results. Quality control is typically conducted using a ZEISS measuring machine, which checks and records the gearings to guarantee the highest standards.
ELECTRICAL DISCHARGE MACHINING.
Imagine a red-hot wire slicing through metal like a flashing sword – not with force, but with pure electricity! Every spark is a tiny explosion that vaporises even the hardest materials. Controlled with merciless precision, the wire moves through the metal like a silent dancer, creating exquisite masterpieces. Wire EDM (electrical discharge machining) is not just cutting – it is an electrical duel between man and metal! And all of this happens, although not as dramatically, in an air-conditioned room in our EDM department.
PRECISION MACHINING.
If higher precision is required, machining is performed using precision profile grinding machines to achieve the desired accuracy for high-precision and complex components. An integrated dressing system facilitates the flexible adjustment of horizontal and vertical grinding wheels for any contours. With a grinding length of up to 1,600 mm and a width of 600 mm, the machine offers a large processing area. A vertical spindle enables complete finish grinding without the need to change the machine. Our range of services encompasses precise machining of hard metal components and profile grinding of HVOF coatings with hardness levels of up to 1,200 HV. And if even higher precision is required, we also offer lapping for maximum surface precision. This technology ensures minimal tolerances and enhanced surface quality, particularly in the case of ultra-precise components with a flatness of up to 2 µm.
FINISHING.
Our Finishing department adds the final touches to our products so our clients can feel true Loll quality in their hands. Here, unwanted burrs, sharp edges, and roughness are removed from components after mechanical processing. This not only enables our quality to be felt but also improves the dimensional precision and functionality of the workpieces. The components are cleaned according to different cleanliness classes in line with the client’s requirements. A meticulous inspection is performed to ensure that all workpieces meet the highest quality standards and are fully ready for further processing or final use.
