Sawing machine specialist Kaltenbach says it is taking three machines to next month’s EMO 2017 exhibition in Hanover, Germany (18-23 September). On Stand C58 in Hall 15, the company will offer visitors the opportunity to see the following machines performing live demonstrations: a fully automatic KKS 463 NA circular saw featuring a new KDV vertical drilling axis; a semi-automatic KKS 450 H circular saw combining automatic material infeed gripper and
L 41 P length stop; and a KBS 400 DG bandsaw with mitre-cutting capability for the processing of steel.

The KKS 463 NA circular saw features a 460 mm saw blade and can deliver ±60° automatic mitre cuts. Flat, angle and solid materials, as well as tubes and special profiles, can all be cut automatically. Further functionality includes the ability to provide multiple front and back cuts, while high quality cutting is aided by workpiece clamping on both sides of the saw blade and infinitely variable adjustment of the saw-blade feed, as well as contactless saw-blade return stroke. Electronic cutting-height adjustment and rapid reverse motion of the saw blade also feature.
Kaltenbach’s KKS 450 H is fitted with a 450 mm saw blade and can provide ±90° mitre cuts. Modern operation is facilitated via a control panel with plain-text display, offering clamping, sawing, reverse motion and opening at the touch of a button. The saw is suitable for single cuts and processing small batches, and there is good accessibility for saw-blade changes and maintenance work.
The KBS 400 DG has a capacity of 400 x 350 mm (w x h). Features include long blade life and high cutting quality due to an inclined saw band, while intelligent material measurement integrated into the clamping system boosts process reliability.

ADS Precision, in partnership with German saw manufacturer MEBA Sawing Solutions, is releasing the MEBAe-cut CNC production bandsaw into the UK market. Powered entirely by electrical drives – making them cheaper to run that a small maintenance saw and devoid of leaking hydraulics – twin-column machines are available in three capacities of 400, 500 and 600 mm, prompting the model designations MEBAe-cut 400, MEBAe-cut 500 and MEBAe-cut 600. Said to be the quietest and cleanest machines on the market, the MEBAe-cut series is aimed at medical, test house, aerospace, automotive and high-precision workshops.

All the drives on MEBAe-cut models are powered by soft-start motors, eliminating voltage spikes. Electrical axles are moved with precision, resulting in efficient power consumption and increased blade life. Indeed, electric-drive systems have a significantly lower power demand when compared with a hydraulic-based system. For example, take material clamping: hydraulic clamping requires permanent pressure that consumes energy during a cutting cycle. In contrast, electric clamps only require energy for the vice movement (clamping and releasing), not during the cutting cycle.
MEBAe-cut machines are equipped with a newly developed electric material clamp. The material is clamped in the main and in-feed vice by a servo-controlled spindle drive. Here, the clamping pressure can be adjusted individually for each application and be preselected via the machine control. As a result, thin-walled tubes can be clamped safely.
The saw feed works via a servo-controlled lead ballscrew spindle with automatically controlled cutting pressure and feed control. A two-handed operating system for rapid vertical movement is included as part of the control.
Although standard models are semi-automatic, MEBAe-cut is also available as a 90° fully-automatic machine, designated by an ‘A’ suffix. Automatic machines feature an ergonomic panel based on Windows CE system software and a 50-program memory.

Until recently, all requirements for sawing at the Nuclear Advanced Manufacturing Research Centre (Nuclear AMRC) in Rotherham were undertaken by subcontractors, but this route was eventually considered to be too time consuming and expensive. It was therefore decided that the most effective solution to all the possible requirements for sawing would be to acquire an in-house sawing facility.

Although usage would be almost exclusively focussed towards research, testing, maintenance or producing samples, often in small batches, it was recognised that any new sawing facility would need to be capable of processing what are termed “exotic” materials to a high degree of accuracy.
After assessing a variety of different sawing systems from five independent suppliers, Prosaw was identified as the company most capable of delivering a cost effective and optimum system suitable for all possible applications. A WH-6056HA twin-column bandsaw was selected as the most advantageous solution and was duly installed by Prosaw engineers.
Says maintenance manager Craig Hamp: “Most of the usage of the saw is intermittent as it is normally for either cutting small batches or one-offs, so whereas volumetric throughput is not normally a prerequisite, accuracy undoubtedly is. This machine certainly fulfils that requirement, regardless of whether it is used for sawing components for maintenance purposes, testing, research or producing samples.”

Vollmer says it is accelerating the processing of carbide-tipped circular saw blades with its new CC 355 production system. The CC 355 enables circular saws for cutting wood to be fully sharpened, including all tooth faces, tooth tops and side angles, in a single working cycle. Four grip arms automatically carry the saw blades from the loading system to the three machining stations. Working through up to 800 teeth per hour, the Vollmer system can process circular saws with a diameter of between 150 and 355 mm.

The CC 355 is equipped with two machining stations for tooth faces and tooth tops, plus one station for side angles. Users can position a stack of un-machined parts either on the left or right, thus providing a free choice of the machining sequence direction and the order that saw teeth are produced. A total of 17 CNC axes control the procedure.
Dr Stefan Brand, CEO of the Vollmer Group says: “The linchpin of our CC 355 is sharpening technology for carbide-tipped circular saws that has been over six decades in the making. Furthermore, the machine’s automated system makes the CC 355 perfect for saw manufacturers who want to produce large volumes of parts, and who also place exacting demands on the tools they use for woodworking.”

A Black Country training provider has pushed the button on a £1.5m extension that will more than triple the size of its facility in Aldridge. In-Comm Training, which was recently awarded ‘Outstanding’ status by Ofsted, has joined forces with workholding specialist Hyfore to develop what it is calling an Advanced Manufacturing Technology Centre next door to its current site in Vigo Place.

Backed by the Black Country LEP’s Growth Deal, the ambitious plan will create an additional 16,000 sq ft of space that will be fitted out with CNC machine tools, automation and a robotics line. The facility will also house material testing, material handling and grinding capabilities, as well as a 16-seat Mastercam and CIMCO CADCAM studio to help students develop their design-for-manufacturing skills.
