A completely new design of bandsawing machine from Kasto was unveiled at MACH 2000 by sole UK agent, Rivers Machinery Called Kastotec, the machine made its world debut at the last EMO in Paris and is a major innovation as it replaces the German manufacturer's principal bandsaw range, designated HBA

High speed M-C cuts light alloys and plastics
The new Prestige machining centre for complex machining tasks in light alloys and plastics, manufactured by the Italian company, FOM Industrie, has been introduced to the UK.
Turning and parting-off heavy tube and pipe
A new range of large capacity, CNC turning and part-off equipment for tube up to 8in diameter has been introduced to the UK by Rivers Machinery under a sole agency agreement.
Whilst suitable for use with bimetal blades, Kastotec has been developed for high production sawing using tungsten carbide tipped (TCT) blades.
Sales of the latter are increasing year on year as manufacturers and stockholders find that titanium may be cut up to seven times faster and steel three times faster than with conventional blades.
Even stainless steel may now be sawn without difficulty using TCT blades.

Dubus machine cuts shower component costs
Sequential sawing, drilling and notching of aluminium extrusions on separate machines have been replaced by multiple machining in a single clamping in a Dubus cell at Coram (UK).
The semi- or fully-automatic machine has polymer concrete in the saw head to dampen vibrations and a CAD-optimised, twin column guide with linear slides on the ways.
These are new techniques for Kasto.
Another innovation which avoids damage to the carbide tips during blade return is the facility to retract the bar slightly and displace the blade so that it travels back without touching the stock on either side.
This has the additional advantage of protecting the surface finish of the sawn faces.
New also is the high level of artificial intelligence included the control which, together with the intuitive operator interface, allows even novice users to extract the best performance from the machine after a very short learning curve.
Automatic selection of infeed and band speed (up to 120 m/min) according to the material being cut avoids blunting the blade or ruining the part.
Even when the machine is operating unattended, monitoring of blade deviation, coolant flow and other functions prevents the cutting of scrap.
There are three machines in the Kastotec range - A3, A4 and A5 - capable of cutting from 10 mm diameter up to 330, 430 and 530 mm diameter bar respectively.
Material feed in a single stroke is 600 mm and minimum cut length is 6 mm.
Regardless of whether single bars or bundles are being cut, the minimum rest piece length of 35 mm ensures minimal wastage of stock.
Installed weight for the largest machine is five and a quarter tonnes.
An extensive variety of material handling options is available from simple roller conveyors to a fully automated storage and retrieval system (ASRS).
Kastotwin is another new bandsaw which was shown for the first time in the UK.
Designed for precision cutting and high output, the new modular machine is available in semi- and fully-automatic versions.
The rigid construction and highly precise band guides make it possible to cut solids and structural steel without having to change the sawband.
The double column design with highly precise linear roller guides combined with hydraulic material clamping both sides of the blade ensures precise cuts and longevity of both blade and machine.
Automatic blade overload protection is provided.
For operator comfort and increased automation, an array of accessories is available including a quick-adjusting measuring stop, chip conveyor, low pressure spray coolant, and infeed / outfeed roller conveyors.
