Variable bed length and multiple milling head options deliver exceptional versatility.
High-Quality Robust Design
• Precisely machined dovetail ways and adjustable gibs ensure smooth and accurate operation.
• All gears and drives are permanently lubricated and sealed for operation in any position.
• Optional hydraulic, pneumatic, or electric motors provide power to the milling spindle.
• Feed options include manual, electric, and pneumatic choices.
• Optional HSK spindle available.
Versatile Functionality
• Two milling head options: 3/4-inch Weldon shank spindle and flexible HSK 40A spindle.
• In addition to manual feed adjustment, 120V and 230V electric feed options are available.
• Electric feed features 0-20 inches per minute (IPM) variable speed with push-button rapid traverse.
• Simple shift lever controls forward, neutral, and reverse modes.
High Rigidity & Durability
• Compact yet highly rigid, suitable for confined or hard-to-reach machining applications.
Exceptional Flexibility
• Cross-slide design allows the milling spindle to be mounted on either side of the bed.
• Can be equipped with a more powerful, versatile HSK spindle using an extended ram.
• Optional HSK milling head swivel base accessory enables 360° full-angle adjustment of the spindle.
• Optional auxiliary riser blocks enhance bed rigidity and increase mounting flexibility.
Quick & Easy Setup
• The PM4200 3-axis portable milling machine delivers precise, versatile on-site milling capability and can be mounted directly on the workpiece or on auxiliary support structures.
• Bed travel lengths: 20, 49, or 78 inches (508, 1244.6, or 1981.2 mm).
Applications
• Commonly used for milling large, heavy parts.
• Many customers use it for weld preparation and remachining of worn components on production equipment such as presses.
• Can be mounted directly onto the workpiece to easily machine long motor mounting slots without disassembly.
• Particularly well-suited for machining motor bases and pump bases in confined spaces.
