What it is
A HAMMOND Machine Works “SLUGGER” 800-ton is a horizontal upset-forging (header/upsetter) press. “Slugger” here refers to forming a hot billet or bar end into a head/collar/flange by “slugging” it axially with very high force.
What it does (process)
A bar/billet—usually heated (hot or warm forging)—is clamped by gripper dies.
The main ram drives the workpiece axially into a heading die cavity, forcing metal to flow radially and create a head, flange, collar, preform, or gear blank.
The part is ejected, then may go to trimming, piercing, or further forging/machining.
Typical applications
Axle and driveshaft ends, gear blanks, valve bodies, flanges, collars
Large studs/bolts and special fasteners (heavy-duty sizes)
Pins and joints for construction/mining equipment
Oil & gas tool-joint preforms and drill-string components
Why this machine is used
Strength: Forging preserves/redirects grain flow → much higher fatigue life than machining from solid.
Material yield: Near-net shapes with less waste than turning.
Throughput & repeatability: Short cycles, consistent dimensions.
Key subsystems you’ll see on the machine
Main hydraulic cylinder/ram (provides up to ~800 tons forming force)
Gripper-die slide with hydraulic actuation and knock-out/ejector
Die blocks & heading cavity (H13 or similar hot-work tool steel)
Hydraulic power unit, accumulators, lube and (often) scale blow-off
Tie-rod frame for rigidity, guards and two-hand safety controls
Operating envelope (typical, not model-specific)
Bar/slug diameters from medium to large sizes
Upsets commonly up to ~2–2.5× bar diameter (with proper preheat and die design)
Cycle time from seconds to tens of seconds depending on part and heat
Peripheral equipment commonly paired
Billet shear/saw, induction furnace, trimming/piercing presses, shot-blast or vibratory finishing, and inline inspection.
In short, this 800-ton HAMMOND SLUGGER is a heavy-duty upsetter/header used to form high-strength preforms and headed shapes in steel and similar alloys with excellent structural integrity and productivity.
