The success of tooling specialist OSG UK continues apace, with the company recently installing another Walter Helitronic tool grinder to meet rising monthly volumes of tool regrinds and orders for new tooling, and to satisfy plans for its latest range of carbide tooling. These tools are joining the company’s own-brand series of taps, thread mills and end mills, as well as drills and reamers.

Supplied by Walter Ewag UK the company’s latest Walter Helitronic, a Power 400, joins existing Helitronic tool grinders and Helicheck Pro tool measuring machine at OSG‘s Basildon site. The ongoing investment by OSG means the company is “superbly equipped to meet all current and immediate future demands”, says director Tony Cooper.

Importantly, the fact that all of OSG’s Helitronic machines have pallet systems and robot loaders makes it possible to pre-load variable size batches of tools ready for effective and efficient processing overnight, unmanned, in batches of up to 30-off. The company says this capability provides the ultimate in order responsiveness for a wide customer base, including aerospace and automotive clients throughout the UK, Ireland and mainland Europe.

The multi-axis Helitronic Power 400 features a mineral cast machine bed and gantry design, and it provides 26 kW (up to 24,000 rpm) of spindle power. Coupled with sophisticated drive technology and X, Y and Z axis travels of 650, 350 and 720 mm, respectively, the machine can handle tools of 3 to 315 mm diameter, up to 520 mm long and weighing up to 50 kg.The robot loader can accommodate tools up to 125 mm diameter and weighing 5 kg.

When Electron Engineering Services,a machine tool company specialising in machine refurbishment and CNC retrofitting, was retrofitting a grinding machine to turn it into an accurate grinder by installing servo systems instead of hydraulics, the company turned to Apex Dynamics and its range of precision planetary gearboxes. Electron selected AB115 and the PAII115 gearboxes for their high precision, hightorque and competitive price.

As part of the project, Electron determined that it needed a precision planetary gearbox fitted to the servo in order to get more accurate performance from the grinding machine and higher torque from a smaller motor.Good availability of parts was essential for timely delivery of the final machine design as Electron had previously encountered problems with other components as a result of supply chain shortages. Other key considerations included high levels of customer support, availability of 3D models for design, and assistance with calculations, in order to meet the project deadlines.

The AB115 is part of Apex Dynamics’ highest precision, highest torque range, while the compact, lightweight PAII115 is an economy precision planetary gearbox with accuracy of less than 6 arc-minutes and reduced backlash.

By installing in-line planetary gearboxes on servo axes, Electron was able to use a much smaller motor in the grinding machine to get similar torque and thrust, with lower backlash and quieter operation.

Phillip Denison, senior mechanical designer at Electron Engineering Services, says: “Having used Apex Dynamics products for some time now, they are really good at what they do and they understand what we do, helping when needed with things like calculations and 3D models. We were really pleased with the levels of service for this project.”
