CA5 EVO boosts 5-axis tool grinding and resharpening centre

The SMP CA5 EVO Boost 5-axis Tool Grinding and Resharpening Centre equipped with a 720 mm table, large selection of accessories, powerful electro-spindle and Easy Grind “all in one” software, is a great machine covering all the needs of small to medium size cutting tools. Mounted with a six position grinding wheel magazine as standard (18 positions optional) the CA5 from French manufacturer SMP TECHNIK is able to unload / load a new wheel in less than five seconds, providing an installation of six grinding wheels of 150 mm diameter.

The rigid nozzle tool cooling system consists of a standard cooling system with two nozzles, with a possible extension of an additional cylinder controlled cooling system.

CA5 EVO boost with robot loader

The HSK40, HSK50 or HSK 10 to 25 Kw high frequency electro spindles are speed adjustable up to 12,000 rpm and include a self-cooling system The 500mm long table provides enough space to install all necessary accessories such as tailstock, fixed steady and diamond grinding system. The SA50 workpiece holder, combined with a direct drive motor with encoders, developing a high speed of 650 rt/mn, allows all resharpening operations.

Renishaw tool probing enables the tool detecting and measuring system to ensure the best resharpening and the best grinding, providing regularity in tool shapes. Due to the heavy mineral casting bed underneath, the machine is vibration proof, offering better rigidity and providing a much better tool surface and finish. EasyGrind full option software is included as standard. This allows programming of all types of cutting tools, from standard tools, complex tools, special applications, 5-axis rectification, drills, radius cutters, taps, mills and reamers to medical tools, form milling cutters and drive tools.

Additional options include: a Renishaw wheel sensor can be mounted inside the machine, allowing the follow up and offset of wheel wear without human intervention; manual tailstock to enable horizontal and vertical adjustment to support long tools during the resharpening operation; a CNC control steady rest that behaves like a 6th axis, controlled by the CN, necessary for steadying very long tools to maintain the quality of the operation.

A robot charger can act as a 6th axis to perform automatic tasks such as changing tools and grinding wheels. The standard version accommodates 200 tool rack/batch, of 16 mm diameter or 104 tools of 32 mm diameter and tool length up to 250 mm.

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

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.
