Actuating Tools and Facing Heads

The MAPAL ISOTOOL Competence Center
in Sinsheim
The MAPAL group develops, produces and markets high quality
precision tools worldwide for the metal cutting industry.
Advice and on site technical service are fundamentally important
issues for customer satisfaction on any market.
In order to meet the demand for complete tooling programs,
MAPAL has also included complex actuating tools and facing
heads in its broad range of products since the 1990s.
Actuating tools from the MAPAL ISOTOOL GmbH in Sinsheim
offer maximum potential for rationalization and optimization
in large batch production. Whether on special machines or
flexible machining centers, wherever complex contours, different
diameters, faces or grooves need to be machined with just
one tool, MAPAL will provide the right tooling solution.
The experienced and highly specialised MAPAL engineering
team will work out the best possible solution with the
customer.
The elaborate, precisely inter-coordinated mechanics and the
large number of different components within an actuating
tool require maximum precision and care at each step of production.
MAPAL ISOTOOL achieves this high precision by an
exclusively manual production process.

The Combination is the thing ...
+ =
The MAPAL actuating tools with guide pads represent all our experiences in metal-cutting.
New types of high performance tools emerged from proven technologies.
Development, design, production and service to the
highest precision provide the basis for products
from MAPAL..
In general, MAPAL provides a guarantee for the function of the actuating tools
developed and produced. For critical trial tools, however, development is always
coordinated and concluded with the customer.
In order to complete the installation of the tools at the customer’s works as quickly
and efficiently as possible, an extensive trials program is conducted for all actuating
tools under extreme stress and real application conditions.
Installation is then carried out at the customer’s works by a MAPAL cutting tool
specialist.
Over the next few pages MAPAL will introduce a selection of typical complex
actuating tools together with the proven series of standard facing heads which are
already in use worldwide.

The wide variety of
MAPAL actuating tools
MAPAL Actuating Tools
MAPAL offers high performance concepts for every machining
task.
The production program includes tools actuated by draw
bars for special machines and tools controlled without
external feed units for machining centers. These are tools
actuated by coolant, spindle speed, centrifugal force or by
contact stop. If the tools have a large overhang, guide pads
based on MAPAL’s tried and tested system are used.
LAT and EAT facing heads are included in the standard
program.
MAPAL Technology
MAPAL TOOLTRONIC® electronically controlled tools with a
high level of function and flexibility are the latest development.
General observations on MAPAL facing heads
Facing heads are primarily used for facing, grooving and NC
contour machining in large batch production on special
machines.
These slide tools, i.e. the toolholder and the inserts, are
actuated by means of an NC controlled cross feed device.
This device is located on the spindle drive unit or on the
rear side of the feed unit and works centrally through the
machine spindle.
The economic high performance cutting operations call for
a type of facing head specifically suited for each machining
task or for a specially designed actuating tool.
For machining cast iron and steel the LAT series is mainly
used, while the EAT series is used for non-ferrous metals
(aluminium).
MAPAL offers 2 standard series of facing heads:
1. The LAT series:
Facing heads with linear slide actuation for large strokes in
the medium spindle speed range.
2. The EAT series:
Actuating heads with eccentric round slide actuation for
small strokes in the high spindle speed range.

Slide
Slide
Coolant pressure
Pressure valve
Draw bar
- Tool feed can be set manually by
means of a throttle valve.
- Slide actuation is achieved by applying
the existing coolant pressure.
Normally coolant at 50 bar is
required.
- Actuating tools can be used on
machining centers with the appropriate
level of coolant pressure.
- Coolant controlled tools are subject
to very low maintenance as
the coolant pressure is not applied
directly on the moving parts but
via a membrane onto an oil pad
which then lubricates the moving
parts.
- Advantage:
A standard machine can be used
without special adjustment.

Axial slide
- Slide actuation is achieved by using
the centrifugal force produced by
two symmetrically aligned pistons
when the tool is rotated. The tool is
automatically deactivated by spring
force after the spindle slows down.

Actuating with TOOLTRONIC®
Motor
- Generating the slide is achieved by
means of a servomotor in the tool.
TOOLTRONIC® actuating tools can
be used on machining centers or
special machines. Machining complex
contours is also possible on a
machining center.

- Advantage:
TOOLTRONIC® provides an additional

Electronics
TOOLTRONIC® – The driving
force in precision machining
MAPAL TOOLTRONIC® has been developed
as a self-contained drive system. By
inductive and bi-directional data transmission,
TOOLTRONIC® provides a full,
additional NC-axis which is incorporated
into the machine control system. This
means that the functions of modern CNC
control systems, such as interpolation of
different axes and adjustment for wear
and blade radius, can also be fully utilised
when TOOLTRONIC® is incorporated.
The new, fully-developed electronic system
sets new standards in the inductively
transferred power of mechatronic tools.
Bi-directional data transmission also
allows any sensor data to be transferred
from TOOLTRONIC® to the machine control,
opening up new opportunities in
machining and control concepts.
The type of block tool to be used with
TOOLTRONIC® depends on the actual
machining task. In principle all selfgenerating
tools from MAPAL ISOTOOL,
which are activated by coolant pressure,
centrifugal force, contact stop or draw
bar, can be driven and controlled by
TOOLTRONIC® as an alternative.
However, possible applications are not
just limited to cutting with a geometrically
aligned blade. Combined with
TOOLTRONIC®, a honing tool with selfgenerating
honing pads to provide compensation
for wear and dimensional
adjustment becomes a block tool.

The LAT facing heads
Here the translatory draw bar movement
of the cross feed device is redirected
by the mechanical slide drive elements
into radial or angular actuating
movements.
The application data – in particular the
cutting speed – resulting from the
machining task, provide appropriate
dynamics at high spindle speeds. As the
traction depends on the spindle speed
and the stroke, the performance of the
cross feed device must be suitably
dimensioned. MAPAL ISOTOOL provides
the appropriate support and the necessary
calculations.
The EAT actuating heads
In conjunction with the relevant
mechanical elements, the translatory
draw bar movement of the cross feed
device is redirected in the EAT actuating
head by a cam control system into a
rotary movement and produces the necessary
swing motion by means of the
excentrically supported rotary slide.
Compared to the LAT system, EAT actuating
heads require significantly less
activating forces and drive power in a
stable, dynamically balanced situation
and are, therefore, particularly suited
for HSC machining.

A Review of MAPAL’s Competence
Reaming and Fine Boring
From the wide range of single and twin-bladed reamers with guide pads, together with fine
boring tools with guide pads and WP or HX blades, to the HPR High Performance Reamers
combined with the MAPAL HFS® Head Fitting System for exact concentricity and accurate
changeover – to give you a general view of our complete knowledge and experience in
pre cision machining bores.
PCD Tools
For pre-machining and finish machining, MAPAL also offers an extensive programme of
pre cision tools with fixed PCD (polycrystalline diamond) blades. This includes precision gun
boring tools plus circular and end milling tools. The programme of face milling heads from
the PowerMill and EcoMill series is characterised by simple, sturdy design and rapid, accurate
blade setting.
ISO Tools
This aspect of MAPAL competence is made up of special tools with ISO elements for gun
boring and milling. This includes precision ground blades in the widest variety of cutting
materials and coatings. The use of MAPAL's tried and tested adjustment system ensures that
the blades are accurately matched to the task. MAPAL offers particular knowledge and ex -
perience in tangential technology.
Actuating Slide Tools
Actuating slide tools offer a high potential for rationalisation and optimisation on special
machines and machining centres. In addition to the conventional facing heads, MAPAL also
supplies EAT and LAT performance-enhanced actuating systems for generating slide tools.
MAPAL TOOLTRONIC® tools with their extraordinary range of functions are the latest development.
Drilling
Yet another area is the product programme for drilling. MAPAL offers the right tool concept
for every task, whether for machining aluminium, steel or cast iron, hard machining or dry
machining or for use in HSC areas. Specially developed coatings and drills with PCD blades
complete the broad-based drilling programme.
Clamping
MAPAL's modern clamping systems, in conjunction with MAPAL's tried and tested reaming
and fine boring tools, guarantee maximum productivity and economy. Whether HSK, ISO or
HFS®, these high-precision connections and interfaces provide the concentricity and changeover
accuracy essential to modern production.
Customer Services
Project planning, maintenance, management and optimisation – the complete CTS® service
package from MAPAL will accompany you from process design to permanent process optimisation
and will ensure optimum and cost-saving use of your tools with the best possible
results.
