Page 9: Main Principles Concerning The Clamping Of Parts
3.2 Main principles concerning the 3.3 Factors that influence magnetic clamping of parts forces The magnetic force lines close between the northern The amount of magnetic flow applied to the part is and southern pole of the magnetic chuck. the factor that most influences the clamping force. To achieve an optimum clamping force, it is neces- sary to apply the greatest possible magnetic flow to the part being machined. - Page 10 3.3.1 Contact surface 3.3.3 Material used The condition that provides the highest resistance to Always check the material of the part that has to be the forces generated during machining is achieved machined in order to verify that it is magnetically when air gaps are reduced to a minimum and there- conductible.
- Page 11 and to the smaller side of the pole (for systems for parallel poles). The clamping force for smaller thick- ness values is inversely proportional to the ratio between the thickness (S) of the part and the theo- retical magnetic clamping section (L), as described above.
- Page 12 3.3.6 Magnetic force This manual applies to two types of clamping sys- tems: • Systems for milling operations • Systems for grinding operations. The circuits of these two types of systems are obvi- ously different due to the fact that the forces used differ and are generally higher for milling operations.

Page 13: Available Models
AVAILABLE MODELS The permanent-electro magnetic systems for mill- ing and grinding operations described in this manual can be divided into the following categories: MAGNETIC CHUCKS WITH SQUARE POLES Series: QX and SQ/ST; HD; HP; CUBOTEC; QX/HN; QG MAGNETIC CHUCKS WITH PARALLEL POLES Series: SGL;... - Page 14 4.1.2 Series QX, MILL TEC and SQ/HD 4.1.3 Series QX and SQ/HP Systems with high density poles suitable for small/ These systems, which can be configured in version medium magnetic chucks. These models have large ST or HD, offer the power required to machine parts magnetic surfaces and can therefore be used to with discontinuous surfaces.
- Page 15 4.1.4 CUBOTEC This system consists of a series of QX and SQ blocks arranged in vertical single bloc units, in the shape of shoulders and magnetic cubes. It is ide- ally suited for horizontal machining centers and FMS systems. The system provides a supporting surface that can be fixed onto machine workbenches and a second surface to support parts with large dimen- sions and weights.

Page 16: Magnetic Chucks With Parallel Poles
4.2 Magnetic chucks with parallel poles 4.2.1 Series SGL Magnetic chucks for milling operations, based on the same technology of QX and SQ, models, but with poles arranged in a parallel configuration. These systems are ideal to machine parts like profiles, rails, bulb plates, etc. - Page 17 4.2.4 Series TFP0 4.2.5 Series TPF Permanent-electro magnetic systems for GRINDING Permanent-electro magnetic systems for GRINDING operations, specifically designed for high precision operations, specifically designed for high precision grinding. These systems differ from model TFP1 be- grinding. These systems have the same character- cause the magnetic surface is coated with a mix of istics of model TFP1, but have a higher polar pitch steel/resin.

Page 23: Positioning The Parts Onto Extensions
Example 1 Example 2 Stop Stop Tool movement MECHANICAL STOPS In other words, the installation of mechanical stops offsets the tangential forces that cause the part be- ing machined to slide, thus guaranteeing maximum safety. Correctly positioning the mechanical stops is very important, in particular when the contact surface between the part and magnetic chuck is small (the same concept also applies to the clamping force). - Page 24 ing force applied to the part is directly related to INCORRECT the number of available extensions. POSITION CORRECT POSITION Use the polar extensions (for milling operations) to verify that all the surface of the part to machine is covered with the polar extensions. The clamping force is directly proportional to the surface in contact with the part to clamp (and thus to the number of polar extensions).
