Refining the jig grinding process with the Moore 500 CPWZ

11/02/2013 / / Comments Off

For the past 25 years FSG Tool & Die Ltd (based in Llantrisant, Wales) have been supplying sub-contract jig grinding capabilities to the manufacturing industry, this is a core part of FSG’s business. After substantial investment in other key areas, the decision was made to invest in new jig grinding technologies to continue to enhance the reputation the organisation has built for the quality and accuracy FSG bring to the surface, cylindrical and form grinding process.

Advances within jig grinding machinery meant that this would now support the modern manufacturing systems employed by FSG.

Finding the best fit solution

FSG were looking to refine their existing processes by seeking a solution that would enable them to operate on an unattended and continuous basis when needed. This would ultimately lead to an additional capacity capability. Heavy emphasis was placed on the need to maintain the supply of the highest quality of components. Compromise was not an option and would therefore allow FSG to develop existing client relationships and create new business opportunities.

NL Machine Tool Consulting Ltd have been working directly with FSG for the past 3 years, assisting them with new investment and sub-contract projects. It was natural that Norman Loughton’s (Director of NL Machine Tool Consulting) expertise within the jig grinding industry would be of assistance during the evaluation and selection process.

A lengthy fact finding process began where FSG reviewed all of the available manufacturers that could supply jig grinding machines that would potentially be the solution that they were looking for. Following a number of internal and external meetings, the decision was made to visit the Moore Tool Company, Inc. headquarters in Bridgeport, Connecticut USA to test the Moore 500 CPWZ Jig Grinding Machine, with Fanuc 31-A Control System.

Ian Slaughter, Business Improvement Manager with FSG Tool & Die Ltd, recalls “The first impressions of Moore were of a company that had a clear business plan to take them forward and place Moore Jig Grinders as the bench mark for excellence.”

During the visit FSG received a factory tour and a chance to use the Moore 500 CPWZ, grinding FSG’s production parts. It was clear that the superior build quality and attention to detail, would lead to a machine that would exceed all expectations and greatly enhance FSG’s capabilities.

After confidently reaching this decision, FSG took the decision to prepare the machine for an additional A + B axis (Tilting Rotary Axis) which will be supplied by Lehmann. This additional axis will allow FSG to refine its existing jig grinding process, along with developing new business. As well as this additional specification the main features of the Moore 500 CPWZ Jig Grinding Machine, with Fanuc 31-A Control System are:

  • X-Axis 500mm, Y-Axis 300mm, W-Axis 350mm, Z-Axis 140mm, Programmable U-Axis, 300kg table load capacity
  • Refrigerated Flood Coolant System
  • Electric Grinding Head Package
  • 20 Position Automatic Tool Changer
  • Renishaw OMP 400 Tool Probe
  • Process Monitoring
  • Motorised Rotary Dressing Station
  • Contact Detector Hearing Device
  • System 3R Workpal Compact 5 Pallet Automatic Loading System

Overcoming concerns

Potential concerns on the support and maintenance cover from overseas based machine tool manufacturers were quickly resolved through the support, maintenance and warranty package set up with Konecranes Machine Tool Service (UK service partner to NL Machine Tool Consulting Ltd and Moore Tool). Konecranes engineers were put through an extensive training programme at the Moore Tool Company facility. This process gave FSG the confidence that the Moore 500 CPZW Jig Grinding Machine will be fully supported through a UK based company and will exceed the capabilities currently offered by most UK based machine tool manufacturers.

The whole process from purchasing to servicing has been enhanced by the involvement of NL Machine Tool Consulting acting as the key link between Moore, System 3R, Konecranes and Camtek.

The future

The new Moore 500 CPWZ Jig Grinding Machine will not only allows FSG to boost existing capacity but also support the constant customer demand for more complex products. FSG has a global footprint in a number of key manufacturing sub sectors such as Medical, Packaging, Defence, and Automotive.

“All of these sub sectors share the same characteristics of constant innovation. For any company in the supply chains, the ability to offer this type of service is a differentiator.” States Gareth Jenkins, Managing Director of FSG Tool & Die Ltd.

To ensure that the demands of clients and service levels are met, FSG purchased the Moore’s Enhanced Accuracy Package. The results of this build philosophy at Moore are quite staggering and will allow FSG Tool & Die Ltd to continue to innovate and stay at the forefront of technical excellence.

IMT TACCHELLA “Tailor-made” solutions for the Automotive industry

06/11/2011 / / Comments Off
Tacchella Macchine. High precision external and universal grinding solutions

Tacchella Macchine. High precision external and universal grinding solutions

IMT TACCHELLA has recently supplied two TACCHELLA Proflex and four TACCHELLA Multitech grinding machines to the Canadian based company LINAMAR for the complete grinding of Input and Output Shafts. An investment highlighting the productivity and versatility of the machines and the first-class processing results. A further reinforcement of IMT TACCHELLA’s specialization in the automotive industry.

IMT Tacchella’s prestigious customer list now includes an internationally renowned company, Linamar, one of the world leaders for the manufacturing of complete transmission modules for the automotive industry. Thanks to the operational flexibility of IMT Tacchella grinding machines, the company has been fulfilling the needs of the automotive sector –where reliability and technology evolution are crucial success factors.

TACHELLA Proflex

TACHELLA Proflex

With TACCHELLA Proflex and TACCHELLA Multitech, IMT Tacchella is at the cutting edge of CNC cylindrical grinding; for this reason, the use of their grinders for gear-box shafts is wide-spread by well-known automotive companies and the supply sector.

The TACCHELLA Proflex is a CNC cylindrical grinding centre for external

and internal diameters – it embodies the core concept of flexible production and it’s the appropriate reply to the market where the current trend is towards reconfigurable installations, with several grinding operations on one machine.

TACHELLA Multitech

TACHELLA Multitech

With TACCHELLA Multi-Tech, IMT Tacchella provides the combination of cylindrical grinding with other swarf removal technologies; in practice, this system can be configured also for finish turning surfaces exempt from thermal

treatment, for “hard” turning, for milling revolution bodies, for boring and for fine finishing.

Linamar: Customer profile and background

Founded in the late sixties in Canada, Ontario, as a small company of mechanical manufacturing, LINAMAR has evolved into an organisation with 12,000 employees and 37 production facilities based in America, Europe and Asia for the design and manufacturing of transmission systems supplied to the major automotive companies, for passenger and Heady Duty vehicles. The high target of its products prompts the Canadian company to keep its manufacturing technology constantly up to date. An instance of this is demonstrated by the New Laredo facility where components of the new dual clutch gear-box are manufactured. To select the supplier, some specific requirements had been set by LINAMAR: the grinding of all the diameters and grooves on Input and Output Shaft in one single workpiece set-up between centres – in order to eliminate all geometric faults of repositioning and the application of the CBN high speed technology combining high levels in finishing and output. These very stringent requirements drastically reduced the group of manufactures being invited to bid: LINAMAR management was convinced to adopt IMT Tacchella solution because of its technological  prominence.

IMT Tacchella solution

The high-speed CBN grinding of three shafts of the dual-clutch gear-box was a LINAMAR challenge that IMT Tacchella has faced up, with the design and manufacturing of six grinders: two Proflex 3 for the machining of Inner Input Shaft, two TACCHELLA Multitech for the Output Shaft 1 and two TACCHELLA Multitech for the Output Shaft 2.

The need to guarantee increased production rates has pushed the manufacturer to conceive a line of machines, each of them devoted to the complete grinding, in one single set-up, of one work-piece type. Choosing specific CBN wheels has drastically decreased cycle times.

TACCHELLA Proflex Close-up

TACCHELLA Proflex Close-up

The TACCHELLA Proflex 3model resorts to ceramic CBN wheels laid out in “R/L/I” configuration, namely the turret on step-less B Axis is fitted with 1 special internal motor-spindle and 2 coaxial spindles, each one with 1 wheel for external grinding, on the right and on the left respectively. Both spindles for external grinding generate a power of 37 kW, the internal motor-spindle a power of 37 kW with a speed of max 12.000 RpM.

The set of tools is made up of 1 right-hand wheel pack diameter 450mm, total width 115mm, 1 left-hand wheel pack diameter 450mm, total width 85mm and 1 wheel diameter 200mm and 15mm thick.

TACCHELLA Multitech Close-up

TACCHELLA Multitech Close-up

On the TACCHELLA Multi-tech both ceramic and galvanic CBN tools are applied in “LS & R/R” configuration, that is on 2 wheel-head units for external grinding: on the first unit there’s 1 single left-hand wheel in fixed straight position, the second wheel-head is a turret on a step-less B Axis with 2 spindles, each bearing a wheel on  the right-hand. Each wheel spindle generates a power of 37 kW.

The set of tools is made up of 1 galvanic CBN wheel, diameter 450mm and max width 190mm, mounted on the first wheel-head unit and of 2 ceramic CBN wheel packs, diameter 450mm and max width 130mm, mounted on the second wheel-head. On both machine models  the Work-head  – specially devised for CBN applications – features a speed ranging from 10 to 5.500 RpM,  with 38 Nm available spindle Torque. The rotation of work-pieces  is started by the friction produced between the special sintered carbide point centres and the  work-piece centres. There’s no need of any additional driving system. Thanks to these configurations the complete grinding of Input and the Output Shaft is carried out in a sequence of just three plunges, within highly performing cycle times.
