The Hammer Drill (Output) Gears – shown on left – are the top and bottom of the same item – a magnificent PM application.

This part is complete as-sintered except for hardening and grinding upper counterbore. RPM‘s multi-platen compacting equipment produces this four-level cross-sectional part with its two external gears, its splined inside diameter, deep upper counterbore and lower counterbore in one operation at several hundred each hour.

In material savings alone – where 1.33 pounds of steel are used to complete a fully machined part – only 0.371 pounds of PM steel are needed for the pressed and sintered PM part – an obvious and significant cost saving. Machining this part from bar stock requires at least 16 operations to complete. PM requires only four, which includes the heat treatment and grinding.

Engineers at Ridgway Powdered Metals are eager to assist its customers in the design of their custom PM components. RPM Engineers and/or its Sales Representatives can consult with customers about the most economical way to produce accurate, high quality parts with the required dimensions, tolerances and geometry.
