Combined sawing and storage at SEW-Eurodrive

SEW-Eurodrive, a manufacturer and supplier of electric motors, gear units, gear motors and associated automation, has installed an advanced storage and sawing system. The system is now in place within a new high-bay warehouse integrated into a recently extended 62,000 m² production facility in Graben-Neudorf, southwest Germany. Both the automated store and sawing equipment were supplied by Kasto.

The order placed by SEW was one of the largest ever received by Kasto in its 180-year history. Within the 4000 m² warehouse is a Unicompact honeycomb storage system with 5140 cassettes offering a load capacity of 3 tonne, as well as an integrated KASTOcenter sawing centre with 450 locations for tube or bar.

Kasto’s Unicompact offers high-density 3D storage in a compact footprint to maximise the use of space. An overhead gantry crane at SEW-Eurodrive transports material to seven KASTOpick split outfeed stations, where lifting mechanisms separate and transfer the material to the infeed roller conveyors of the saws.

Eight automated KASTOvariospeed C 18 production circular saws process stock up to 180 mm in diameter. The heavy-duty, CNC production saws cut solid material – as well as tubes and profiles – to length.

The Kasto sawing centre comprises buffer storage for material and a KASTOtec SC 4 bandsaw with infinitely variable cutting speed. Stock that includes tool steel and challenging materials such as titanium and nickel alloys from 22 to 260 mm in diameter is cut into individual pieces. A KASTOsort robot handling system sorts and stacks the cut pieces. The solution independently selects grippers, containers and stacking patterns, while automated guided vehicles retrieve the boxes of cut pieces and transport them to their destinations in production.

A KASTOlogic warehouse management system (WMS) ensures seamless flow of material throughout the facility.

Metal distributor gains from saw automation

Innovation is at the heart of the metalworking industry, and it takes centre stage at Walter Metals. Nonetheless, theOhio-based tool steel distributor for Ellwood Specialty Steel was experiencing bottlenecks because its four manual bandsaws were inefficient and required a significant amount of operator interaction to handle material.

General manager Mike Kaufman says. “They needed replacement, also due to their age. We therefore started exploring options for how we could do things better, faster and safer.”

The company eventually purchased two HBE411A Dynamic automatic horizontal bandsaws from Behringer.

“We looked at three or four other manufacturers, but none of them had the level of automation on the handling system that we saw with the Behringer.”

Behringer also reportedly presented the lowest total system cost when compared with the other competitors under consideration. The saw builder’s extensive parts inventory and enthusiastic team of technicians further solidified the decision to partner with Behringer.

“They have a large amount of supplies and spare parts on the ground in the US,” Kaufman says. “As far as service goes, typically we get resolutions in under 24 hours.”

The Behringer bandsaws at Walter Metals straight-cut solid round bar from 2 to 10inch diameter. The workpiece materials are tool and die steel, such as D2 and S7, most annealed up to 42 HRc hardness.

With the introduction of the Behringer saws and their automated systems, WalterMetals witnessed remarkable improvements.According to Kaufman,efficiency soared as the company reduced material handling time by 50%. He says: “We do almost two times the amount of production on two saws than we did previously on four.”

Bandsaw training, commissioning and re-training

The bandsaw has evolved significantly since its invention in the 19th century. But with such a great utility comes complexity; operating a bandsaw machine safely and efficiently requires an intimate understanding of the machine’s workings, its potential hazards and the techniques to leverage its full potential. Saws UK therefore provides a guide to bandsaw training, commissioning and re-training.

Regardless of the specific type of bandsaw, be it horizontal or vertical, metal-cutting or wood-cutting, comprehensive training is crucial. Recognising the need for expert-led, comprehensive bandsaw machine training, the Saws UK University took shape.

Training begins with a deep dive into the machine’s architecture, exploring each part’s function and interaction with the whole system. Participants are guided through the myriad components of the bandsaw, from the blade, guides and wheels, to the motor and the drive system. Operators also learn about safety, daily machine operation and bandsaw maintenance. As participants progress, they delve into more advanced topics, such as fine-tuning machine settings for different materials, troubleshooting common issues and mastering advanced cutting techniques. 

The process of bandsaw commissioning sets the foundation for the successful operation of the machine. It is the initial set-up, where the bandsaw machine is assembled, installed, tested and adjusted to ensure it operates as efficiently and safely as possible. This is why bandsaw commissioning is an essential component of the training programme at Saws UK University. 

Bandsaw machine re-training ensures that operator knowledge and skills remain current, aligning with the latest developments in bandsaw technology and industry practices. Saws UK University tailors re-training sessions to the needs of attendees, covering everything from basic refresher courses to advanced workshops focusing on new technologies and techniques.

Unilap steps into new sectors with Vollmer

Darrell Hughes founded South Yorkshire Saw & Tool Co in 1974 as a small saw blade sharpening and ancillary supply company. Wind forward almost 50 years from the inception of a company working out of a two-bay garage and the transformation of the Doncaster-based company is beyond comprehension. Everything has changed. The company name, the facility, the industries served and the manufacturing processes.In fact, the only remaining constants are the long-serving personnel, family ownership and sharpening technology from Vollmer UK.

Changing its name in 1992 to Systco Unilap, the saw blade sharpening company acquired its first Vollmer machine in the late 1970s and has bought a complete suite of German-built machines over the years. To manufacture the countless product lines with thousands of new, re-sharpened and serviced tools delivered every week, the company has 11 Vollmer machines.Three arrived in 2022.

With 25% annual post-Covid expansion in traditional markets and growth in new segments, Unilap needed capacity, hence its investment in a Vollmer CHX840 with HS loading system in April 2022. Quickly following this machine was a Vollmer QXD250 with HC5 loader in July, with a Vgrind 260 with HC4 loading system arriving in October of the same year.

The reasoning behind the CHX840 and the QXD250 was simple. Unilap purchased the automated CHX840 saw blade sharpening machine to add unmanned ‘lights-out’ running and alleviate capacity on the 22-employee company’s other saw blade manufacturing and servicing machines. Likewise, Unilap already had a nine-year-old Vollmer QXD200 machine running around the clock, so upgrading to a brand-new QXD250 would add capacity and support rapid growth in the metalworking industry.
