EXHIBITION PREVIEW MACH 2020 – BIRMINGHAM NEC – 20-24 APRIL
customers
Introduced
in 2018, Pionex
Series taps will be on the stand,
but with new tweaks. Launched with the
headline of 30% less torque required, the
new Pionex Series includes 45° helix
geometry with a reduced rake angle, back
tapering and improved relief that combine
to provide unprecedented performance and
swarf removal. The new Pionex is available
with metric threads in course or ne pitch,
as well as UNC, UNF, BSP in all diameter
and pitch variants with a complete line of
special thread designations also available
upon request New also is the SpyroTec
Series of Twisted HSS and HSCO
countersink tools, which will also be
presented at MACH. A world- rst series
incorporates a unique spiral uted
geometry with convex cutting edges such
that 90° countersinks can comfortably cut
virtually all material types with improved
concentricity, precision and performance –
axial and radial forces are both reduced by
more than 60%. A specially designed TiAIN
coating ensures higher wear resistance
and a high temperature hardness that
guarantees longer tool life for nearly all
materials and applications. The standard
SpyroTec size programme is from 6.3 to 31
mm diameter with a 90° countersink that
conforms to DIN 335 form C. A number of
shank lengths are offered, with boxsets
with a range of diameters available.
Heidenhain
now offers
conversational
programming for
trochoidal machining
#CNC – Heidenhain, Stand
6-275 New software to
support conversational programming of
trochoidal machining routines and new
grinding control capabilities that can also be
exploited via conversational programming
are stand messages New software
incorporated within TNC control systems,
widely tted to machining centres and millturn
centres, allows complex trochoidal
milling routines to be programmed
conversationally on the shop oor. The OCM
(optimised contour milling) functionality,
available for TNC640, TNC 620 and TNC
320 CNC systems, will be demonstrated for
the rst time in the UK at MACH. OCM builds
on trochoidal milling’s traditional bene t of
high material removal rates when slotting,
considerably expanding the range of
application. In addition to the roughing of
any open or closed pocket or island, the
software also offers cycles for nishing the
oors and side walls. The milling tool’s wrap
angle can be limited to reduce heat
generation and prolong cutter life. As cutting
forces are lower, delicate and thin-wall parts
can be machined with greater accuracy and
even spindles with low power and torque can
be used successfully. Moreover, as the
milling cutter occupies less of the area of a
slot or pocket during machining,
accumulation and re-cutting of chips is
minimised. This is particularly important for
features that are deep in comparison to
their width. The control automatically
calculates the best toolpaths for maintaining
constant cutting parameters. The
subsequent machining operation runs with
continuously optimised cutting values,
resulting in increased machining speed and
a noticeable reduction in tool wear. In a
second WNT innovation, an exchangeable
head milling system that combines a solid
carbide head with a steel body to deliver
the performance of solid carbide but
with cost and productivity gains,
especially in high-feed, long-
overhang applications
commonly found in the diesinking
and aeroforms, with
focus on machining titanium
alloys, tool steels and light
alloys. Flute design delivers
increased chip ow and tool life,
with gains of over 400% and 550%
respectively, compared to a competitor
product. On an environmental note,
MultiLock also reduces the amount of
carbide required. System heads are
available in a range of sizes between 12 and
25 mm, as well as a variety of cutter styles,
including torus, high feed, ballnose and
deburring cutters Ceratizit has a brand
new turning insert grade, CTPX710.
Developed as a multi-application grade
utilising the latest Dragonskin coating
technology and new carbide substrate,
CTPX710 allows just a single grade to be
used across many material groups, covering
superalloys to general steels and nonferrous
materials. CTPX710 inserts are
available in a wide variety of standard ISO
shapes and in three geometries. These are
-M34, aimed at turning superalloys, -25P,
which has a sharp cutting edge providing
good swarf control on softer materials and
-25Q with wiper technology to deliver higher
feedrates and improved surface nish.
#tooling – Guhring, Stand 17-400
Latest milling, threading, holemaking
and special cutting tools, alongside
established product lines, will feature on the
company’s stand Making a debut
appearance at MACH will be the new
MTMH3-Z ‘Drifter’ series of helical drilling
thread-mill products. Capable of thread
milling in material up to 66HRc, the Drifter
series combines core drilling and threading
in a single operation. With a shank diameter
from 3 to 12 mm and a neck relief from 5 to
40 mm, it is suitable for creating threads
from M2 to M16 on all steels and stainless,
duplex, cast and graphite iron, aluminium
and Titanium alloys. In support, CNC Guhro
Thread Mill software is free to download for
