consumption is reduced. The Unibend Control Software is a key element of the machines, and exploits the underlying architecture to deliver versatile tube- bending capability. A major addition in the new software release is ‘graph analysis’. This utility captures data on the torque values that each machine axis applies during a programmed tube bending operation. By comparing the torque data required to bend new material batches against a ‘golden’ example, the information can help to identify any changes in the quality of material. Another utility, called ‘performance analysis’, has been enhanced to record more information on machine usage, including the timings of start and stop button presses, idle time and parts produced. This raw data on the productivity of a manufacturer’s tube bending capital equipment can help to generate a detailed picture of shop-floor operations, to aid in the analyses of operational efficiency and productivity.

Tube bending software sets new standards

Unison, UK, has produced a range of new software utilities for its all-electric tube bending machinery. The tools in the latest release of the Unibend Control Software include detailed torque analysis software for each axis to allow fabricators to track tubing quality and compare suppliers. The software also includes a utility that captures usage data to assist productivity

analysis, and the ability to dynamically control the profile of the carriage push cycle, for fine control of bend quality. Unison’s Breeze family of tube bending machines use servo motors instead of hydraulic force to control the bend process, including clamp, pressure die, mandrel and follower.

Thisall-electricactuation provides benefits in repeatability and energy consumption. Following set-up, all operating parameters are stored, allowing machines to be configured for further batches of parts in a few minutes, and without creating any scrap.

Improving overall yield in tube mills with TIMCAL lubricants and descaling agents

Timcal offer for seamless tube production can be divided in three main categories:

ROLLIT® Lubricants . Based on high purity primary syntethic graphite are applied to the mandrel bars to protect them, reduce friction, withstand high pressure and temperature during rolling process. ROLLIT® Descaling powders to treat the scale on shell interiors and/or lubricate the shell. Products blown into the hot shell before mandrel insertion. ROLLIT® Technologies . Reliable and sure allow a perfect application of ROLLIT ® products on the most severe conditions and control the quantities applied.
