Compact second-operation vice

During rough machining first operations it is good to have a known datum, which is where WNT’s ZSG4 Centric vice system provides a suitable solution.

However, when it comes to second operation work, a known datum on the component has already been created, so the requirement for a centric-jaw system is reduced, and it is here that the newly developed WNT ESG5 fixed-jaw vice from Ceratizit fully complements the ZSG4.
Providing identical footprints, with the vice bases measuring 160 mm in length (and an overall height of just 83 mm), the ESG5 and ZSG4 can sit side by side either directly on the machine table, or on WNTs MNG Zero Point baseplate system. In terms of clamping performance, again, the two vices are identical with a maximum gripping force of 35 kN, allowing components to be gripped securely on as little as 3 mm of material.
According to the company, accuracy and repeatability of ±0.01 mm are achieved by the overall vice design with precision matched slides, and the use of a ball screw to control jaw movement. The ability to switch jaws between the two vice types adds further versatility and compatibility to the WNT work-holding system. This compatibility opens up the choice of jaw from the range, which includes: reversible jaws; pendulum plate jaws; combi jaws; aluminium jaws; five-axis jaws; smooth carbide-coated jaws; and stepped jaws.
Says Adrian Fitts, business development manager at Ceratizit UK & Ireland: “The WNT ZSG4 vice has proved popular as it provides a cost-effective, efficient and compact work-holding solution. With ESG5 we have listened to customers and created a vice that fully complements ZSG4 and enhances the work-holding systems available from Team Cutting Tools.”

MACH postponed until January 25-28

The Manufacturing Technologies Association (MTA), which owns and runs the MACH exhibition, has taken the decision to reschedule the show from April 2020 to January 2021.

Given the spread of Coronavirus, the MTA has decided that, in order to minimise the risks to visitors and exhibitors, the event will now take place on 25-28 January 2021. The show will still be held in the same halls at the NEC. All exhibitors that had booked for MACH in April will be offered the same stand space at the event held on the new dates.
James Selka, MTA CEO, says: “We believe that this decision, which has not been taken lightly, is in the best interests of the industry and those who work in it. Our first priority is, of course, the health and safety of the 30,000+ people who will visit and work at MACH. In addition, we believe that by moving MACH to January 2021 we are going to be able to offer a better experience for our visitors, and better value for our exhibitors, than by holding it in April under the conditions likely to be in place at that time.”

Software set to take centre stage

FASYS and NCSIMUL will be on show as part of Hexagon’s production software portfolio. The latest releases will be demonstrated along with Hexagon’s range of various CADCAM and production control packages. NCSIMUL is on Stand 412 in Hall 20, with the other eight software systems on Stand 600 in Hall 19.

Continuing the company’s ethos of powering a successful digital ecosystem, NCSIMUL manages the complete machining process, from the NC program to the machined part, including automatic G-code reprogramming and simulation. The current release contains a number of important enhancements to both high-end machining verification and the module, which automatically converts CAM and NC programs to different machines. FASYS, meanwhile, supports the entire manufacturing workflow, from conception to the final product, including design and planning through to NC programming.

Lasers from TLM

Lasers continue to find their way into a growing number of industrial applications, in many instances offering an efficient and more cost-effective alternative to traditional technologies and processes, and this is certainly the case for laser cleaning, claims TLM Laser.

The company represents 4JET within the UK and will be showcasing the handheld JetLaser surface processing system. Potential applications for this technology include the cleaning of moulds, tools and fixtures, as well as paint and coating removal operations, plus pre-treatment of surfaces prior to welding, gluing or coating. TLM laser will be located on Stand 763 in Hall 6.

Rotary tables at MACH

Rotary table specialist PL Lehmann is looking forward to welcoming customers on Stand 28 in hall 17 at MACH 2020 (Birmingham NEC, 20-24 April). Since 2018, the company has been directly represented in the UK and Ireland with sales and services. PL Lehmann prides itself on close relationships with partners from the machine-tool industry. Indeed, its scope of supply for rotary tables allows interface with most vertical machining centres and grinding machines.

The compact Lehmann rotary tables show their advantages by being light in weight and small in footprint, but strong when it comes to clamping torque and load weight. These attributes means users can still use quite a bit of space on their machine tables for three-axis operations as room remains for additional vices.
Lehmann’s modular system is based on four sizes of rotary table, which are expanded by a building kit to create customer solutions. With a clamping torque range of 250 to 5000 Nm, spindle load capacity between 17 and 1600 kg, speed from 40 to 300 rpm, and accuracy of 2 arc-sec, the company says its rotary tables are in a class of their own.
The range also permits the creation of different fourth-axis solutions with up to four spindles, tailstocks and counter bearings, as well as a five-axis solution featuring a strong and precise rotating and tilting axis. In addition, the modular systems allow a direct encoder and special labyrinth sealing for grinding applications.
