Tech Update
Electric CNC Tube Benders Hold Up to Four Tool Sets
From Horn Machine Tools (HMT), Madera, CAL, comes a line of all-electric CNC benders with tube capacity from 2 to 10 in. The clamp and pressure dies are equipped with large electric servo motors, and the Quad Stack design allows the user to mount as many as four sets of full-sized bend tools at once. This provides the flexibility to rapidly switch between sizes, or allows for greater capability to bend complex shapes. Options include a shearing device and load/unload automation for continuous production.
These machines are designed intentionally for 24/7 produc- tion, say HMT officials. They can bend tight-radius stainless steel on the rated diameter size. Draw bending in combination with push rolling capability are included as standard features.
Says president Kent Horn: “Production tube bending is not sim- ply a matter of faster bending speed, it is a combination of all of the axes moving fast in simultaneous motion to reduce nonvalue- added cycle time. Fast clamping, stack shifting and carriage posi- tioning will improve production rates as well as bending speed.” Horn Machine Tools: www.hornmachinetools.com
Blanking Line Combines
Punch and Cut-to-Length
Shear to Accelerate
Edge-Profile Production
Two years ago, German manufacturer Wirth GmbH, a producer of vacuum-based lifting equipment, had to decide whether to add a punch to its 20-yr.-old blanking line, or buy a new machine. The decision: Buy new, and it selected a Schuler Powerline S blank- ing line with an integrated, fully automatic punch. Installed ear- lier this year, it’s already paying dividends.
“We received an order for 34 metric tons of edge profiles—parts to 6 m long, which a single employee operating the new line com- pleted within 8 hr.,” reports production manager Rainer Roth. “That’s
