Rotary tables, rotary-tilting tables, tilting heads equipped with electrospindle: these are some of the products that Lcm Precision Technology designs, produces and markets. Innovative and customized solutions in manifold geometries, with different sizes and various magnitudes, with which the company intends to represent a reliable and qualified partner in national and international ambit.

Headquartered at Castell’Alfero, in Asti province, Lcm Precision Technology is an engineering company that since 1986 has been designing, producing and marketing accessories for machine tools. Forefront components developed thanks to a team of skilled technicians able to comply with specific needs and to turn them into high quality added-value solutions. Result enabled by the precious contribution of around ninety employees, a dozen of whom working in the Research & Development Department, for a turnover that reaches about 15 million Euros (70% of which beyond the borders).

«A high-quality product – specifies Giorgio Panatero, sales executive of Lcm Precision Technologythat in most cases directly reaches machine tool manufacturers, that is to say OEM, and is also intended for OE applications».
In this context, the company sets research and development activities as strategic and priority for its growth, with the addition of the capability and the will of collaborating in co-design and in co-engineering with its customers, in order to find innovative solutions to obtain more and more advanced technical specifications.
«Without neglecting the technical after-sales support – adds Panatero – in the phase of preparation and development of the plant, with which we bear out the manufacturer in the process optimization. Not a mere product sale but, undoubtedly, a collaboration relationship that allows us to stand out on the market and improve our competitiveness level in national and international ambit».

The right technology for everybody
Rotary tables, rotary-tilting tables, tilting heads equipped with electrospindle: they are some of the products designed, produced and marketed by the company.
«A production – adds Panaterpo – that includes both tables with conventional rotation system, that is to say mechanical, with worm screw and crown, or with direct-drive, torque motors. Flexibility with which we can satisfy the various market requirements».
It is worth underlining that torque motors have been designed and manufactured for about ten years directly inside the company. A dedicated department, in fact, “tailor-dresses” motors according to the specific application and precise performance requirements.
«A further differentiating element – underlines Panatero himself – that allows us not to have to adapt our requirements to the technical catalogue specifications of third manufacturers, giving us the possibility of optimizing what is necessary for the application and the operational ambit».
The torque motor technology permits the company to manufacture tables with torque performances in operation resembling the tables with screw-crown system but very high rotation speeds. Another important advantage is the backlash absence and the consequent high dynamic response and precision, thanks to the quick bi-directional response.

From milling to turning
The range developed by Lcm Precision Technology can be practically subdivided into three big families where innovation and competences converge. The first includes the rotary tables belonging to BRC and BRS series, solutions conceived for the application on 5-axis machining centres, equipped with rotary-tilting system directly integrated into the bed of the machine itself. They are executions implementable in the sizes of 200, 300, 400, 600, 800 mm (sizes of the rotary surface), up to the biggest one, with 1,200 mm plate and a loading capacity that can reach 2,000 kg.
The family called MD includes instead tilting milling heads (with +/- 100° for those with mechanical transmission and hydraulic clamping and +/-120 for the models with torque motor), the related milling electrospindles (belonging to the ELQ series) and the rotary tables to be integrated or fixed on the machine worktable (being part of TDE/M and TRB series).
«Product typologies – further underlines Panatero – manufactured upon specification of the manufacturers of milling machines and machining centres that intend to implement 5-axis machines in the various morphologies».
The above-mentioned solutions are completed by the inserted rotary tables for machining centres, that is to say with 4th and 4th/5th axis, with rotary plate sizes from a minimum of 125 to a maximum of 350 mm.

Product line constantly widened thanks to the release of numerous novelties. Among them, also those recently presented to the market and mainly connected with the evolution of the turning world.
«In other words – adds and ends Panatero – the possibility, which more and more often the manufacturers of milling machines are trying to supply to their customers, of executing also small turning operations on their machines. Concerning this, we are developing a series of targeted products, both rotary tables that can rotate with speeds consistent with turning, and we are speaking of 500 rpm on 800 mm of diameter and electrospindles and heads able not only to mill but also to manage, to grip and to clamp a turning tool».
