NEW TOOL FOR TURNING TITANIUM
CAN BE MONITORED WITH SENSORS
A new insert geometry for grooving and
parting off titanium has been introduced by
German tool manufacturer, Horn. It ensures
reliable chip breaking and a soft cut, leading
to high feed rates and fast machining times.
Additionally, tool longevity is increased by
up to 60 per cent. Type 224 inserts with the
new WT geometry are available in
increments of 2, 2.5 and 3 mm in carbide
grade IG35 and are designed for Horn's H224
tool holders.
Coupled with this development, the Swiss
group Kistler, working closely with Paul
Horn GmbH, has developed a novel system
Tooling expert Walter GB has announced a
range of two new solid carbide taps and a
thread milling cutter targeted specifically at
producing threads in hardened steel.
TC388 Supreme and TC389 Supreme solid
carbide taps are for 50–58 HRC and 55–65
HRC materials, respectively, while the TC685
Supreme thread mill is for workpieces up to
44 HRC hardness levels.
The TC388 and TC389 Supreme taps have
special cutting geometries that fully shear off
the root of the chip when reversing,
minimising torque peaks that are common
with blind hole machining; for example,
when the reversing of the tap can result in
fractures.
In addition, the new geometries also
prolong the tool life and increase process
reliability, and the need for oil lubrication
for real-time monitoring of tools used in
micro turning applications. The Piezo Tool
System (PTS) consists of a force sensor
inserted into the turning tool holder that
provides information on the condition of the
tool during cutting.
The small piezoelectric sensor, which can
be replaced easily and quickly, can measure
even the tiniest of cutting forces to a high
resolution. A machine operator is
immediately able to identify a defect in the
material being cut or a tool breakage,
resulting in minimum scrap, maximum
quality, lower production costs and
increased productivity.
In micro turning applications, alternative
measuring systems are not practical.
Monitoring the drive power of the spindle
motor is not able to detect the minute
variations. Measuring acoustic emissions
does not deliver satisfactory results
consistently when small workpieces are
being machined. Visual monitoring also has
to be ruled out, as coolant together with the
high rotational speeds would obscure the
view of the machining process.
The new PTS solution is compatible with
selected standard turning tool holders from
Horn, does not require any adjustment to be
made at the control and can be used on any
lathe.

WALTER TAPS INTO SOLID CARBIDE FOR
SUPERB THREADING OF HARDENED STEELS
has been replaced by the use of emulsion.
Generating maximum process reliability
and long tool life, the TC685 Supreme orbital
drill thread mill produces the core hole and
thread (and chamfer, if required) in a single
operation.
Its face milling geometry produces
stabilising forces in the axial direction to
improve stability and reduce deflection –
with the result of fewer radius corrections
and reduced wear. In addition, its 15° helix
angle and internal coolant guarantee chip
evacuation.

SHAKING UP
THE MARKET!
New range of MACH Machine Tools’ CNC
bed mills equipped with the sophisticated
DynaPath WinDelta control is guaranteed to
cause a stir.
MACH Machine Tools, part of the
Vigilance Group, has recently introduced a
new range of CNC bed mills equipped with
the advanced DynaPath control.
There are three machines in the range -
the MDM 700 (X-, Y- and Z-axes = 710mm,
400mm and 500mm) the MDM 850 (X-, Y-
and Z-axes = 830mm, 500mm and 610mm),
and the MDM 1000 (X-, Y-and Z-axes =
1000mm, 500mm and 610mm).
In addition to the machines’ powerful ISO
40 taper spindles (up to 5000rpm spindle
speed) and generous working tables (up to
1524mm (L) x 330mm (W) with a maximum
load of 500kg), all three models are equipped
with a range of value added features
supplied as standard.
These include a 12.1” touch screen, MPG
hand wheel, air draw bar, interlock table
guard and coolant equipment. They are also
Wi-Fi enabled to facilitate ‘remote’ diagnostic
and online support.
The MDM range of machines deliver
exceptional cutting performance and are
equipped with the DynaPath WinDelta
control system which gives the machines a
definite ‘edge’ when it comes to speed,
flexibility and reliability.
The DynaPath control system is
inherently versatile and features
conversational and ISO/G code
programming capability making them easy
to program on the shop floor.
An 8Gb on-board (program) storage
facility combined with 1000 line look ahead
ensures fast processing speeds and
responsiveness which, in turn, help deliver
high part accuracies and superior surface
finishes.
