METAL WORKING

SMT Precision Cylindrical Grinding Machines are designed and manufactured to achieve high accuracies of roundness and cylindricity of the jobs. It has separate internal and external grinding heads, suitable for both production as well as tool room applications. MACHINE BED Close grained graded casting (FC 25) with box structured adequately ribbed design, provides very high rigidity and thermal stability in long run. WORK-HEAD The machine has a Rigid Universal Work Head. It has an alloy steel spindle running on unique hydrodynamic bearings having self-alignment of clearance for different speeds. During dead center grinding a simple adjustment completely eliminates the clearance in the bearing thus providing rigid support to the jobs. The bearing arrangement gives wear free operation. WHEEL-HEAD The wheel head has a very rigid spindle running in Hydrodynamic Multi-point Bearings. The Spindle is made of alloy steel, specially heat treated (sub-zero) to achieve high accuracy and stability for long life, Spindle cartridge unit is easily interchangeable. INTERNAL GRINDING HEAD Internal Grinding Head is mounted separately on the in-feed slide thus providing a rigid support to the spindle giving better surface finish in grinding. Internal grinding operations can be done after removing the external wheel.
