Expect square and parallel tolerances within 0.001 inches, supporting accurate setups in toolrooms and production lines.
CME Tools Magnetic Workholding Surface 7″ x 4″
The 7″ by 4″ CME surface emphasizes fine-pole construction for compact workpieces. Its versatile application covers surface grinding, drilling, and light milling with consistent, high-precision clamping. A durable steel body and sealed design protect against contaminants, helping maintain performance in mixed shop environments. Parallelism remains within 0.001 inches for reliable setups.
CME Tools Magnetic Workholding Surface 18″ x 6″
For larger parts, the CME 18″ x 6″ surface provides a 120 psi magnetic force with a fine-pole layout. Its solid steel construction supports heavy workpieces during surface grinding, drilling, EDM, and light milling. The surface remains square and parallel within 0.001 inches, preserving accuracy across extended cycles in toolrooms and production lines.
SEDY Heavy Duty Bench Vise With Magnetic Jaw Pad
The SEDY bench vise combines a heavy-duty clamp with a magnetic jaw pad for protection and flexibility. Its 4.5″ jaw offers multi-jaw functionality to securely hold flat or round materials without surface damage. Built from premium gray iron, the vise is engineered for longevity in workshop, welding, and milling tasks. Easy installation and a stable base support consistent performance for repeated operations.
POWERTEC 6″ Magnetic Vise Jaw Pads, Set of 2
The POWERTEC magnetic vise jaw pads provide quick, tool-free attachment to vises. Designed to hold wood, plastic, metal, tubing, and irregular shapes, these pads protect surfaces from clamp marks while offering reliable magnetic grip. The included two-piece set makes it easy to customize clamping surfaces for varied workpieces and milling tasks.
Buying Guide: Key Considerations For Magnetic Workholding In Milling
- Magnetic force and pole design: Higher force with fine-pole arrangements improves holding for delicate workpieces and reduces surface marks. Check stated force densities (N/cm² or psi) and pole spacing.
- Size and compatibility: Match the chuck or surface size to your milling table and the typical workpiece dimensions. Larger surfaces support bigger parts, while compact boards excel with small fixtures.
- Material and durability: Look for high-quality magnetic steel or solid steel bodies with corrosion resistance and sealed construction to withstand coolant, dust, and contaminants.
- Precision and flatness: Tolerances like 0.001 inches for square/parallel relationships help achieve repeatable results in grinding and milling operations.
- Ease of use: A straightforward on/off mechanism or simple magnetic jaws reduces setup time and minimizes handling risk for workpieces.
- Versatility: Consider whether the system supports vertical use, drilling, EDM, or light milling, expanding its utility across different machines and tasks.
- Maintenance: Regular inspection of pole gaps and surface cleanliness improves longevity and clamping consistency.
- Cost-effectiveness: Weigh initial cost against long-term reliability, maintenance needs, and potential productivity gains from faster setups.
In summary, the best magnetic workholding for milling combines strong, uniform magnetic force with durable construction and precise tolerances. The options above cover a range of sizes, from compact 7″ x 4″ and 6″ x 12″ chucks to larger 18″ x 6″ surfaces, along with practical accessories like magnetized jaw pads and bench vises. Consider your typical workpieces, machine type, and required precision when selecting a solution.
