DCM Tech Model PDG Semi-Automatic Punch & Die Grinder | S/N 453000

For sale is a highly reliable, industry-standard DCM Tech Model PDG Rotary Table Surface Grinder. Specifically engineered for precision tool sharpening, this automatic plunge-feed grinding station is designed to maintain and sharpen turret press, ironworker, progressive die, and rooftop tooling from major brands like Amada, Trumpf, Wilson Tool, and more.

Dating to circa 1999–2000, Serial Number 453000 represents the highly sought-after tactile era of DCM machinery. Unlike later iterations outfitted with expensive and delicate LCD touchscreens that can glitch or degrade over time in a heavy shop environment, this unit features ultra-rugged, tactile push-button switches and discrete electrical relays. Maintenance mechanics prefer this specific generation because it relies on standard, non-proprietary components that are incredibly straightforward to service and maintain.

Key Features & Operational Highlights

• Constant-Contact Grinding Principle: Unlike general surface grinders where the wheel sweeps back and forth over a part, the PDG locks rigidly in position over the workpiece. The rotary table and the tooling rotate continuously under a plunging vertical head, ensuring uniform material removal with absolutely no streaks, burn marks, or heat-induced stress lines.
• Turnkey Automatic Downfeed: Operators simply touch off on the tool surface using the physical indicator to establish the zero point, dial in the desired material removal depth, and start the cycle. The system automatically steps down in highly uniform increments, dwells for a perfect spark-out finish, and shuts itself down.
• Built-In 0° to 10° Angle Tilt Sub-Base: The universal indexing mounting assembly features a built-in tilt plate. This allows operators to quickly dial in and grind factory-spec rooftop punches, shear angles, and complex progressive tooling dies without needing complex secondary fixtures.
• Through-Spindle & External Coolant Flow: Dual high-volume coolant lines (both through the center of the grinding spindle and via an external adjustable nozzle) flood the point of contact to eliminate hot spots and extend tool life.
• Large-Bore 3-Jaw Indexing Chuck: Accommodates standard 6.5” three-jaw chucks. The deep interior bore allows operators to drop in both thin and thick turret station punches without stripping off their spring packs, dramatically lowering cycle downtime.
