High-speed double end finisher for stamped

metal bushings WHEN a leading stamped metal bushing manufacturer asked Haven Manufacturing about improving productivity, Haven did not hesitate to accept the challenge. Haven is known for its fast and reliable double end finishing equipment, but customers always want even faster machines. Standard feeds and speeds for different

materials and size usually dictate the machine’s cycle rate, which is generally between two and three seconds. In this case standard cycle rates were not fast

Haven speeded up the cycle rate

no tool chatter. The quality obtained at these speeds was said to be excellent. Haven’s ability to innovate and create solutions that specifically address customers’ needs is what the company prides itself on. Its flexibility, both mechanically and electronically, demonstrates the breadth and depth of the challenges it is willing to face to help a customer. Haven is a full service, turnkey supplier to the tube processing industry.

enough. In order to compete with off- shore competition, the cycle time had

to be reduced to between one and 1.5 seconds. Haven engineers worked with the customer to design a tool set and feeding sequence that would obtain a stable process at those speeds. The result – an average of 1.2 seconds. The combination of servo spindle feed control with a custom-designed part clamping system produced precision finished parts with

that helps to produce multiple forming and machining operations to the work piece in a single cycle. Automatic working optimisation of tooling turret movement features up to fifteen powered workstations with rotational and linear movement capable of expanding, end forming, beading, facing, chamfering, closing, threading, tapping and flaring.

designed to offer high productivity, ex- cellent quality and long work life. All Pedrazzoli electric tube benders are equipped with FANUC digital motors, servo amplifiers and connection cables. The CNC language is ISO or G-code generated automatically by the Pedrazzoli Intelligent Motion control post-processor series 4. All Pedrazzoli machine structures are manufactured from high-grade steel. The Pedrazzoli Stern Brown series electric end forming machine series has a special design

ERCOLINA has announced the addition of Pedrazzoli CNC tube bending and end forming machines to its family of bending machines. Pedrazzoli’s established Bend Master Series offers fully electric axis control, including clockwise and counter-clock- wise bending during the same cycle. A multi-stack tooling design is capable of producing fixed or variable radius bends. Linear guide movements feature re-circulating ball spheres, brushless motors and a rigid mechanical structure
