SP250 – PLC Single Pass Honing Machine

PLC SP 250 is a two spindle machine for components of bore diameter up to 25mm and length up to 50mm. Here the design is two shafts and four stations wherein two stations are always idle for the purpose of loading and unloading of the component.

Single pass honing process, as the name indicates, is passing the honing tool once in the bore. The tools are barrel shaped and pre-set with consecutively increasing size. The tool is passed through the bore while it is rotating. Conventional honing tool reciprocates, expands while honing and retracts after completion of cycle. While Single Pass honing tool is slow wearing diamond impregnated, adjustable and pre-set to size, it does not have to expand and retract during the cycle. Hence, consistency of the bore size is ensured. We have shared key insights about Honing machines on our blog page.


SP425 – CNC Single Pass Honing Machine

SP425 is a 4 Spindle Single Pass Progressive Honing Machine with bore limit of 5-15 mm and maximum bore length of 75 mm. It is developed extraordinarily for little segments with high creation volume. Bore accuracy is unto 2 microns and the maximum production every day can be 5000 parts.

While Single Pass honing tool is moderate wearing diamond impregnated, movable and pre-set to measure, it doesn't need to extend and withdraw during the cycle. Consequently, consistency of the drag size is guaranteed. The procedure is generally appropriate for parts like Gears, associating bar, rocker arm, gear shifter fork, shrubbery, pressure driven valve, wrench instance of hermetically fixed blower, sewing machine segments, gun barrels and so forth. Applying Single Pass Diamond rough Bore completing innovation, incredibly close resistances can be accomplished reliably in large scale manufacturing at a lesser per piece cost.
