Grinder for small OD tools

Vollmer, a specialist in tool grinders, has launched the VGrind 340S. Complementing the existing VGrind series of machines, the latest VGrind 340S has been specially developed for producing and re-sharpening small carbide tools with diameters from 0.3 to 12.7 mm.

Drills and milling cutters in this size range are in high demand in the automotive, electronics, connector and medical engineering sectors, where assembly space and components are becoming smaller and smaller. Automation options on the VGrind 340S allow tool manufacturers to use the machine for unmanned production around the clock.
The VGrind 340S is not just suitable for producing rotationally symmetric tools, but for re-sharpening; relying on the company’s tried-and-tested VGrind technology to achieve this functionality. VGrind see two vertical spindles made available for different grinding wheel sets, which makes it possible to reduce non-production time. Five harmonised CNC axes achieve interpolation, with short travel distances for the linear and rotary axes. These machine kinematics reduce idle times and the subsequent time required to machine workpieces.
As well as the rotary axes, the linear axes are also designed as direct drives (linear drives) for the first time. Unlike ball screws, these axes are non-contact drives and are therefore not subject to wear, increasing the service life, precision and longevity of the machine. The VGrind 340S also features a steady rest to ensure optimum tool concentricity during grinding, while a back rest is available as an option for longer drilling tools.
NUMROTOplus software enables a 3D simulation of the tool production process and makes it possible to carry out collision monitoring in advance. The height-adjustable and pivoting touchscreen control desk, as well as the generously dimensioned view of the machining space, make for ergonomic machine operation.

Streamlining AM simulation

Additive manufacturing (AM) expert Renishaw is collaborating with Simufact to enhance the success of laser powder bed fusion (LPBF) builds through accurate simulation and streamlined AM preparation.

The collaboration includes the integration of Renishaw’s QuantAM build preparation software into Simufact Additive 2020. Also, the two companies are working together on improving the simulation of complex material metallurgies found in the process to enable the successful prediction and compensation of stress and distortion during printing operations.
Included within Simufact Additive 2020 is an integrated Renishaw QuantAM API for build job preparation and export, which provides the user with an error-free data transmission from Simufact Additive directly to Renishaw systems. This functionality also improves productivity because the entire work process, from design to printed part, is possible within the software. QuantAM API now enables multi-laser build file preparation for Renishaw’s RenAM 500Q quad-laser machine.

MTC appears on best companies list

Coventry-based Manufacturing Technology Centre (MTC) has been listed at number 57 in the ‘75 Best Companies to Work For in the Midlands – 2020’.

The achievement comes hot on the heels of the Sunday Times ‘100 Best Companies to Work For in 2020’, which listed the MTC at number 77 nationally. Dr Clive Hickman, chief executive at the MTC, says the accolade reflects the efforts taken to make sure the MTC is a great place to work, and that employees are engaged, valued and looked after: “We make great efforts to ensure the MTC is a happy and satisfying place to work, while at the same time challenging our people to fulfil their potential.”

More staff at Ward CNC

After a year of high business growth, Ward CNC is ramping up its staff levels with several key additions to the team.

The latest employees are being announced to underpin the current growth trajectory, but also to support the company’s ‘More Than Machines’ philosophy, which is dedicated to further enhancing its commitment to customer service, from initial introduction and application requirements, through to sales, delivery, installation, training, spares, consumables and technical support.
A key appointment sees Ward CNC appoint Richard Hunter Rowe (pictured) as its head of sales operations. Joining the company in January, Rowe is a member of the senior management team and his role is to devise national sales strategies and operational support plans. He will ensure the sales team is positioned to deliver growth objectives and fiscal budgets, as well as shaping future strategic objectives.

Removing 3D-printed parts from base plates

The MEBA3D 335 is said to be a fast and cost-effective solution for the removal of 3D-printed parts from their base plates. Well before 3D sawing became a trend, MEBA had developed a concept for separating 3D-printed parts from the base plate that offers fast process times and good cutting results, with low operating and cost expenditure. The MEBA3D 335 concept is based on the straight cut saws of the MEBAeco product family, which are designed to offer high efficiency and optimum cutting results.

This metal-cutting bandsaw is equipped with a special clamping device for mounting plates that can be precisely aligned in order to release the 3D printed workpieces exactly on the customer’s own mounting plate. MEBA’s saw can be fitted with a housing in the working area of the saw that protects against dust, and with an additional suction device, if required.
Compared with conventional production processes such as wire EDM, MEBA says that its 3D saw concept is extremely uncomplicated, with just a few operating steps: simply clamp and saw. Acquisition and maintenance costs are also said to be significantly lower, while the long service life of the saw blade is another factor that helps keep costs low.
Utilisation and amortisation of the saw are further enhanced by the fact that MEBA3D 335 saws can also be used for standard sawing operations with a minimum of changeover effort.
An additional advantage of the MEBA 3D system is that, in many cases, existing MEBA saws are compatible and can be upgraded easily and economically. The system was successfully demonstrated to visitors at the Formnext exhibition in Frankfurt during November.
