LIP, LIF Exposed Linear Encoders
Accuracy grades better than ±3 μm
Exposed linear encoders
Exposed linear encoders from HEIDENHAIN operate with no mechanical contact between the scanning head and the scale or scale tape. Typical areas of application for these encoders include measuring
machines, comparators and other precision devices in linear metrology,
as well as production and measuring equipment, for example in the
semiconductor industry.
Accuracy grades of ± 0.5 μm and better
Measuring steps to 0.001 μm (1 nm)
Measuring lengths up to 30 m
No friction between scanning head and scale
Small dimensions and low weight
High traversing speed
The exposed linear encoders of the LIP and LIF types are characterized by small measuring steps together with high accuracy. The measuring standard is a phase grating applied to a substrate of glass or glass ceramic.
LIP and LIF encoders are typically used for:
Measuring machines and comparators
Measuring microscopes
Ultra-precision machines such as diamond lathes for optical components,
facing lathes for magnetic storage disks, and grinding machines for ferrite components
Measuring and production equipment in the semiconductor industry
Measuring and production equipment in the electronics industry
The LIDA exposed linear encoders are specially designed for high traversing speeds up to 10 m/s, and are particularly easy to mount with various mounting possibilities. Steel scale tapes, glass or
glass ceramic are used as carriers for METALLUR graduations, depending on the respective encoder.
LIDA exposed linear encoders are
typically used for:
Coordinate measuring machines
Testing machines
PCB assembly machines
PCB drilling machines
Precision handling devices
Position and velocity measurement
on linear motors
POSITIP, ND Position Display Units
For up to 6 axes
A digital readout (DRO) consists of one or more linear encoders for traverse measurement and a display unit for position values. DROs are typically fitted or retrofi tted on:
Machine tools such as milling, drilling and boring machines, lathes, electrical discharge machines, grinding machines Measuring machines
FEATURES:
User-friendly functions for easier operation of manual machines and equipment
Axis designations and functions adjustable for milling, drilling, boring
and turning
Problem-free installation, maintenance-free operation
Fast payback with economical use
POSITIP, ND Position Display Units
For up to 6 axes
Due to their performance range, the position
display units of the ND 200 series are predes-
tined for measuring and inspection stations,
but are also intended for simple positioning
tasks such as infeed for a circular saw or the
stroke of press travel. The switching inputs
and outputs of the ND 287 permit operation
also in simple automated environments. A
large graphic TFT monitor displays the
measured values, the status and the
soft-key row.
FUNCTIONS
The standard position display ND 280 provides the basic functions for simple measuring tasks. The ND 287 features numerous functions for measuring, processing and statistically evaluating positions, for example sorting and tolerance check mode, minimum/maximum value storage, and measurement series storage. These data make it possible to calculate mean values and standard deviations and display them in histograms or control charts. With its modular design, the ND 287 permits optional connection of a second encoder for sum/difference measurement or of an analog sensor, for example for temperature compensation.
iTNC 530 Contouring Control
for milling, drilling, boring machines and machining centers
HEIDENHAIN TNCs are versatile, featuring both shop-floor programming, and offl ine programming, and are therefore ideal for automated production. They handle simple milling tasks just as reliably as the iTNC 530, for example, can perform high speed cutting—with especially low-jerk path control—or 5-axis machining with swivel head and rotary table.
TNC part programs have long lives because they are upwardly compatible. Programs from older TNCs can also run on the new models. When moving up to a moreadvanced TNC, the user merely builds on what he already knows.
The iTNC 530 from HEIDENHAIN is
a versatile, workshop-oriented
contouring control for milling,
drilling and boring machines as
well as machining centers. It
features an integrated digital
drive control with integrated
inverter, which enables it to
produce a highly accurate
workpiece contour while
machining at high velocity.
The iTNC 530 controls up to
13 axes and spindle. The
block processing time is 0.5
ms. A hard disk serves as
program memory medium.
The iTNC 530 hardware option with two processors additionally features the Windows XP operating system as a user interface, enabling the use of standard Windows applications.
