Influence of Position Measurement on Accuracy in 5-Axis Machining
High strength and low weight are essential for the aeronautics and space industry. Integral construction has established itself as the way to minimize the weight of “airborne” parts: components with complex structure are manufactured completely from a single blank. Metal removal levels can be as high as 95 %. This high “buy-to-fly” rate leads to high costs for the raw material of the blanks.
The New Generation of Angle Encoders Come of Age
HEIDENHAIN’s angle encoders with integral bearing have long been the standard for applications where angular measurement in the range of a few angular seconds is necessary. The encoders are characterized by their simple mounting and very high accuracy.
Aspects of Energy Efficiency in Machine Tools
Discussions of the efficient use of energy have become more frequent in many sectors of industry. Machine tools comprise numerous motors and auxiliary components whose energy consumption can vary strongly during machining. The main spindle drive, for example, and the coolant system work near their rated power during roughing with a high stock-removal rate, while the power consumption during finishing is significantly lower.
NEW LC 200 – Absolute Linear Encoder for Machine Tools with Long Axes
Machine tools for the manufacture of large parts for the space and aeronautical industry, for construction of large turbines, or for large dies in toolmaking, all have at least one long servo axis. On these machines, axis lengths of several meters are nothing out of the ordinary.
NEW Encoders for High Speed Spindles
Spindles are among the key components of a machine tool. Their characteristics are determined by the design, the drive and the bearing systems. Position feedback encoders play a decisive role particularly for the drive performance. HEIDENHAIN is presenting the NEW ERM 2400 encoders, ideal for applications that offer little space and yet require a relatively high accuracy of angular measurement.
