ID, OD, Face, Taper, Radius, Contour Grinding in Single Chucking
Eastec 2017: Hardinge Grinding Group, a subsidiary of Hardinge Inc., will showcase its USACH 100‐T4 machine for ID/OD precision cylindrical grinding in a variety of industries.
Hardinge Grinding Group, a subsidiary of Hardinge Inc., will showcase its USACH 100‐T4 machine for ID/OD precision cylindrical grinding in a variety of industries. The machine is said to combine ID, OD, face, taper, radius and contour grinding in one chucking. Thanks to the generous 500-mm (19.68") cross-axis travel (X axis), the machine processes parts as large as 450 mm (17.7") in diameter and as heavy as 272 kg (500 lbs).
Other features and options include as many as four motorized grinding spindles; a high-precision measuring probe; a torque motor B axis; a high-precision hydrostatic workhead (B1 axis); a Siemens or FANUC control; an option for simultaneous face and ID grinding; and an option for full or partial automated part loading/unloading.
In vertical grinding, the workpiece is held upright in a rotary chuck with the grinding spindle overhead. This configuration can improve roundness, facilitate single-setup processing and prolong the life of the machine. Loading and unloading may gets easier, too. Workpieces with relatively large diameters and short lengths benefit the most from vertical grinding.
If one must pick a manufacturing specialty, grinding carbide might not be the first choice because it’s perceived to be very difficult. RPM Carbide Die, however, has worked the material for nearly 40 years and, as specializing seems increasingly to be the order of the day, this northern Ohio shop is in a good position to thrive.
Because creep-feed grinding is essentially a milling process, why not use a VMC? A grinding machine supplier describes how a VMC platform can make creep-feed grinding more effective.
