Tacchella Proflex
External and internal cylindrical grinding machines with up to four grinding wheels
Tacchella Proflex external and internal cylindrical grinding machines are the ideal solution for precision grinding, including on gear shafts, bearings, pump gears and spindles in small or large quantities and at multiple diameters or machining interpolations. Tacchella Proflex grinding machines enable round, non-round and polygonal workpieces up to 400 kg to be ground with absolute precision. The series covers grinding lengths from 400 to 1,600 mm with a center height up to 305 mm.

ADVANTAGES
HOW TO BENEFIT FROM TACCHELLA PROFLEX EXTERNAL AND INTERNAL CYLINDRICAL GRINDING MACHINES
Enhanced performance
The monolithic machine bed on Tacchella Proflex grinding machines is made of stabilized and ribbed cast iron and offers peripheral channels to catch the coolant. The machine bed perfectly intercepts the thermal changes and vibrations that arise during grinding to ensure outstanding quality of the ground workpieces.
Top precision
The workpiece headstock with a fixed or rotating spindle is ideal for live grinding operations and grinding between centers. High-precision bearings with a rounding accuracy below 0.001 mm enable positioning of the workpiece headstock on a swiveling frame. The tailstock is hydraulically driven. It has a safety device for regulating the pressure between the points and the resulting axle load, as well as a micrometric system to correct the workpiece's cylindrical properties.
Maximum flexibility
These multi-tasking grinding machines permit the combined use of 2, 3 or 4 conventional grinding wheels (610 and/or 760 mm) or CBN high-speed grinding wheels (400 and/or 500 mm). A workpiece headstock with C-axis is also available for machining non-round parts like cams, eccentric tappets, even polygons, threads and personalized profiles.
Ideal ergonomics
The grinding wheel carriage slides on hydrostatic guides for maximum compactness and enhanced sliding behavior. Intersection guides on the X-transverse axis and Z-longitudinal axis reduce space requirements at floor level and enable rational arrangement of the fluid and electrical systems.
APPLICATIONS
TOP PERFORMANCE FOR MAXIMUM PRECISION
Tacchella Proflex external and internal cylindrical grinding machines are the perfect solution for grinding the likes of gear shafts, bearings, pump gears and spindles in small or large quantities – and at multiple diameters or machining interpolations.
- Powertrain
Drive shaft
Tacchella Proflex external/ internal cylindrical grinding machines with movable grinding headstock and two independent grinding wheel spindles grind all grooves and diameters on drive shafts. Also with CBN grinding wheels with ø 450 x 100 mm at 120 m/s.
- Powertrain
Differential housing
Use Tacchella Proflex external and internal cylindrical grinding machines with a swiveling double-spindle and conventional ø 610 mm grinding wheels at 63 m/s for precise grinding of differential housings, including in-process measurement.
- Transmission
Input shaft
Tacchella Proflex external and internal cylindrical grinding machines with a swiveling 3-spindle grinding headstock and ø 610 mm grinding wheels operating at 63 m/s can machine the external diameter and shoulder on input shafts in three operations and a single setup.
- Engine
Bearing
Tacchella Proflex external and internal cylindrical grinding machines enable precise grinding of bearings in three angular positions. 5°: longest external diameter, shoulder and shorter diameter. 0°: ball ring and ball bearing surface. 180°: internal diameter.
- Engine
Camshaft
Tacchella Proflex external and internal cylindrical grinding machines enable precise grinding (CBN grinding wheels with ø 400 mm at 120 m/s) of a wide variety of camshafts with maximum flexibility and short setup times. - Even for small quantities.
- Miscellaneous
Punch
The three-spindle Tacchella Proflex enables precise grinding of punches. Wheel 1: definition and roughing of the profile by interpolation of X and C. Wheel 2: finish grinding of all profiles without cavities and on the concave sides (3 pages).
