The Engineering Technology Group (ETG) is now offering UK manufacturers the new B-Safe from Balance Systems. B-Safe expands spindle and machine-tool diagnostics according to vibration and temperature analysis. The miniaturised system installs directly on to the machine’s spindle, guaranteeing real-time monitoring and the reduction of machine downtime by predicting malfunctions and potential failures. However, the system can provide so much more. Based upon fully customised solutions from ETG, B-Safe has an overload alarm, an overheating alarm with programmable thresholds that correlate with real-time data from process monitoring, and can create a collision alarm within 1 ms
B-Safe easily retrofits to virtually all machine tools and spindles. The system consists of a B-Safe sensor with a connector or integrated cable, a UPS and TCP-IP connection device interface, a start-up kit with software and user manual, a wide range of extension cables, and M5 to M12 adaptor and magnetic support that can all be fitted with simplicity.

Options include an event logbook, tri-axial real-time data recorder, high-frequency mono-axial data, FFT analysis, a collision waveform recorder, historical trends, spindle check-up, service notes and the ‘Fingerprint’ feature (a B-Safe app intended for condition monitoring of machine tool and machine tool spindle based on vibration analysis).
This information and much more is available in the always-connected HMI, while the multi-platform software provides users with full control from anywhere. The B-Safe HMI is a software platform that allows interaction with multiple sensors at the same time and is available in different languages and layouts. It is suitable for PCs or machine-tool control panels that run Microsoft Windows 7, 8.x or 10.

Accudyne Products is introducing its expanded-capacity bar puller for CNC lathe automation. The new EZ-Puller Expanded Capacity supports larger round bar diameters of 0.093” to 2” (2.7 to 50.8 mm) and weights of up to 100 lbs (45.4 kg). Hex bar capacity of 0.25” to 1.375” (6.4 to 34.9 mm) and square bar capacity of 0.25” to 1” (6.4 to 25.4 mm) are pulled without the need for an M19 (spindle orientation) function.

The EZ-Puller is an auto-adjusting bar puller that enables the automatic operation of CNC lathes. Notably, the auto-adjust feature is driven by an ‘X’ value in the pulling sub-routine of a lathe program. This value represents the distance the tool needs to move in the X axis according to the bar diameter being pulled.

Accudyne’s patented design uses a cam and lifter system, where hardened steel grippers attach to hardened steel pivot arms. These arms have an integral cam lobe machined at their top. As the grippers advance over the bar stock, internal urethane springs compress. The urethane springs provide a reactive force that allows the grippers to securely hold the bar stock. This proprietary design provides optimal gripping force regardless of bar size or shape.

Other features of the EZ-Puller are that it will accommodate an infinite range of sizes within its capacity without mechanical adjustment, allowing for multiple pulls. Multiple pulls are used for longer parts that cannot be cost-effectively machined in one chucking. The design of the EZ-Puller also allows for pulling bars with minimal projection in front of the work-holding chuck. This characteristic allows the machinist to set-up with as little as two gripper serrations (0.12”/3 mm) of engagement, which makes for a more rigid set up.

The Centrotex quick change-over interface from Hainbuch is now available in a new version for smaller machine spindles. Acclaimed by the company as the market’s smallest system for setting up clamping devices in a matter of seconds, the quick-change Centrotex S has a diameter of just 224 mm and offers repeatability better than ≤0.002 mm on the interface without having to re-align.

Hainbuch’s Centrotex S is a solution for eliminating non-productive downtime, set-up times and job changeover times that often increase when access to a compact work envelope is restrictive on operator movement and access. Featuring a fast change-over system and compact design, the Centrotex S eliminates excessive set-up times and is particularly suitable for compact machine tools with a small work envelope.

The machine adaptor mount on the spindle and the clamping device is equipped with a counterpart adaptor that can exchange with another clamping device in less than a minute. Actuation of Hainbuch’s Centrotex S is via just one radial locking screw, while ergonomic operation is now better thanks to the fewer rotations required to tighten and clamp the system. In addition, the Monteq changing fixture contributes to a faster clamping device set-up.

The new Centrotex S is suitable for clamping parts up to 52 mm diameter, and for A2-5, A2-6, AP140 and AP170 spindle nose systems.

Additionally, the Centrotex S system can offer a solution in fixed position clamping set-ups on the bed of machine tools. According to Hainbuch, the precision, rigidity and clamping forces can significantly improve machining performance, surface finishes and tool life.
