Ricardo installs spiral bevel grinder

Investment by Ricardo in gear-manufacturing machines has improved productivity and extended capability, as the recent investment of £1.5m in a Klingelnberg spiral bevel grinder underlines.

The Klingelnberg equipment is now installed and commissioned at Ricardo’s Midlands Technical Centre in Leamington Spa, and is producing components of precision and quality for the current range of motorsport and sports car transmissions being made by the company, while simultaneously supporting the development of a new series of products destined for market release in the near future.
In addition, the company has acquired new design and quality assurance capabilities through software upgrades such as the KIMOS (Klingelnberg Integrated Manufacturing of Spiral Bevel Gears) software package from Oerlikon.
Dick Elsy CBE, CEO of the High Value Manufacturing Catapult, recently toured the Ricardo Midlands Technical Centre to see the new equipment in action, and said: “It’s great to see Ricardo at the forefront of digital manufacturing with investment in adaptive machining. Their new spiral bevel grinder is already delivering great results in terms of process capability and productivity improvement. I was very impressed”.
Ricardo Performance Products MD Martin Starkey, adds: “The investment in manufacturing technology and software, including the purchase of the Klingelnberg grinding machine, has enhanced Ricardo’s capability to design, analyse, manufacture and inspect bevel gears with a closed-loop system. This willingness to invest underlines our commitment to digital manufacturing development, and the new technology is a key enabler in supporting our customers with more advanced solutions, meaning they can look forward to even higher standards of product quality and shorter lead times.”

Kellenberger K100 released

Hardinge Group company Kellenberger has released its K100 for medium and high-technology grinding operations. The K100, which was on show at the recent EMO exhibition in Hanover, was equipped with a WeFlex automatic loader to demonstrate the flexibility of the modular concept and its suitability for operating in automated, high-volume factory environments.

In terms of functionality the K100 platform delivers a diverse range of configuration options for a wide range of grinding operations. Thanks to the modular solution on one common platform – and the new assembly concept designed to reduce throughput time – it is possible to optimise production costs for the machine and ensure an attractive price-to-performance ratio.
The user-friendly and ergonomic design of the machine is based on a new, simple operator guidance system with an intuitive 19” touchscreen panel. K100 machines are equipped with the latest Fanuc 31i CNC controls, optionally available with newly designed cycle programming or workpiece-related graphic programming.
Three important features distinguish the K100 machine series: the collision-free compact wheel-head solution; an enhancement of its performance parameters; and the service-friendly machine design concept.
The new tandem wheel-head is a compact construction featuring a motor spindle. A reinforced casing accommodates larger grinding wheel diameters for internal grinding, while a choice of 10 wheel-head variations allows the optimum layout of the machine based on the components to be processed.
Enhancement of performance parameters include higher grinding wheel drive power for increased productivity, a newly designed Z guideway for precision profiling and a C axis with direct drive for greater precision when performing non-circular grinding.

Leader balances the benefits

Leader Chuck International provided demonstrations of Balance Systems’ range of solutions at the recent Advanced Engineering 2019 exhibition in Birmingham, UK.

In the spotlight was grinding-wheel balancing, in-line dynamic gauging, touch detection and spindle monitoring with the B-Safe machine tool monitoring system.
Mark Jones, managing director at Leader Chuck International, says: “Balance Systems’ knowledge and experience of grinding process systems helps to improve the quality of the workpiece. They offer the capability to reduce grinding-wheel wear and speed-up cycle-time, while extending machine lifetime and increasing operator safety.”
Spindle and grinding wheel balancing is an essential operation in order to achieve workpiece surface quality and ensure long life for the rotary components.
Says Jones: “We offer a range of systems based on balancing heads that can be installed externally or built into the spindle. Control units are equipped with cable and contactless solutions, and provide constant vibration monitoring. The newly designed ‘Absolute Balancer’ technology is characterised by high performance levels in terms of execution speed and balancing precision for single and two-plane applications.”
In-process measuring systems offered by Balance Systems allow manufacturers the opportunity to produce components that conform to specification even under the most severe environmental conditions, such as warm-up, thermal shifts, chemical coolant, local or induced vibrations, and so on, and to operate using high-speed cycles.
The close control of grinding wheel balancing and its dresser helps attain a near perfect profile, while also optimising the removal of the grinding wheel surface, as evidenced by longer tool life.Identification of the instant when the tool touches the workpiece is essential to minimise cycle time, reduce ‘air grinding’ and optimise axis infeed.

Laser roughening and honing machines

The EA211 evo engine from VW has been manufactured using the latest technologies to increase efficiency, such as coating of the cylinder liner. Set to install new production lines in China, Gehring has received an order to supply the laser roughening and honing machines for this purpose.

Dr Sebastian Schöning, CEO of the Gehring Group, who oversees the firm’s development strategy, says: “We are happy that we were able to achieve concrete environmental improvements together with our customer.”
The thermal coating of cylinder bores is a highly sought-after technology for increasing the efficiency of internal combustion engines. Gehring is focusing on optimising the process chain of: laser roughening – coating – honing. In order to produce a strong bond between the coating and engine block, efficient roughening processes are required to ensure overall functionality.
Gehring’s laser roughening technology is said to bring about operative advantages. For instance, apart from cost savings and an improved working environment, there is also a positive effect on overall engine design. In addition to high adhesive tensile strengths with low roughness, economic advantages take effect in mass production, since no wearing tools are needed and coating material is saved. Both aluminium and cast iron can be pre-machined with the laser-refining process.
Gehring laser-roughening machines have two spindles with novel rotation optics for the simultaneous machining of two cylinder liners. The co-ordinated process steps (roughening – coating – honing) lead to low friction and wear-resistant cylinder liners, which contribute to more compact and efficient internal combustion engines, says the company.

Advanced Grinding Solutions at EMO

Advanced Grinding Solutions (AGS) had no less than 10 of its machine manufacturing partners exhibiting at the recent EMO 2019 exhibition in Hanover: Rollomatic (tool grinders); Bahmuller and Tschudin (internal/external and centreless grinders); HandlingTech (automatic loading systems); Gerber and Magnetfinish (deburring machines); FLP (lapping and fine-grinding machines); Nova (external/internal grinders); Platit (coating machines); and Comat (filtration systems).

Rollomatic showed many tool grinders, including its six-axis 830XW for manufacturing large diameter cutting tools that has a novel combination of hydrostatic guides and linear motors for high levels of surface finish. Also of major interest was the Rollomatic LaserSmart 501 machine for machining PCD, CVD, and natural diamond tools. The 501’s machining speed is stated as being up to four times faster for processing multiple features such as cutting edges, chip breakers, and cylindrical lands in one operation. The machine has four cameras for complete and easy viewing of all laser operations. Rollomatic also used the show to debut its NP50 machine for the grinding of cutting-tool blanks.
Tschudin was exhibiting its latest ‘Cube’ grinder, which is stated as being the world’s smallest CNC centreless grinding machine, while HandlingTech displayed various loaders for machines, including its advanced palletZ and ecoZ models.
Platit exhibited its most flexible coating machine, the Pi 411 Plus, while Gerber focused on three brushing machines for deburring components, including the new Eco-Innovation, which received its worldwide debut.
