The PMCH Series is a specialized Rotary Magnetic Fixture for high-precision cylindrical grinding and angular indexing.
Standard chucks must be bolted to a separate rotary table.
The PMCH features an Integral Spindle Design.
The magnetic body and the rotary shaft are molded as a single integrated unit.
Provide superior rigidity and lower runout.
This unit is ideal for grinding angles, flats, and radii on round components.
It features a Fine Pitch Magnetic Face suitable for holding small precision parts securely.
Key Features & Benefits
Integrated Rigid Design:
The “Main Body” and “Rotary Spindle” are one piece.
This monolithic construction eliminates the error stack-up found when bolting separate chucks to rotary tables.
Precision Indexing:
The spindle features a high-visibility graduation scale (360∘) engraved directly onto the ring.
Vernier Scale Accuracy:
Come with a precision Vernier Scale (referred to as “Cursor Film” in older manuals).
Allow operators to set angles with significantly higher resolution than standard degree markings.
Structural Stability:
The ON/OFF switching mechanism can be completely isolated from the face geometry.
Switching the magnet does not cause the face to deform.
Ensure flat and parallel results every time.
Pro-Tip
Indexing Applications:
This tool is perfect for “Grinding between Centers” or manufacturing punches.
You can grind a flat, rotate the chuck exactly 90∘ using the scale.
And grind a second flat to create a perfect square punch.
High-Stability Grinding:
Because the magnetic face is micro-pitch, the magnetic field is shallow.
This prevents the “magnetization” of the bearings or the machine spindle.
Protect your equipment from collecting metallic dust.
Common Specifications for Both Models
Magnetic Pitch: Fine Pole (0.5 mm Brass + 1.5 mm Steel) available for holding small parts.
Switching: Manual Hex Key activation.
Environment: sealed against grinding dust and coolant splash.
