PIPKM300 Keyway Milling Machine

The PIINC PIPKM300 Portable Keyway Milling Machine is a compact, lightweight 3-axis portable milling machine designed for on-site machining and workshop maintenance. Equipped with a magnetic mounting base and precision-ground dovetail guideways, it is suitable for machining small surfaces and cutting or refurbishing keyways on stationary workpieces.

With its compact structure, magnetic mounting system, and 1.6 HP motor, the PIPKM300 provides a practical solution for maintenance tasks where moving a large workpiece to a conventional machine shop is difficult. An optional V-mounting base expands its capabilities to include machining shaft-type workpieces, such as cutting new keyways or repairing worn keyways.

Key Features and Benefits

1. Compact and Portable Design

• Lightweight construction with a machine weight of approximately 78 kg.

• Compact design helps simplify transportation and setup at different job sites.

• Suitable for on-site maintenance and workshop machining where space is limited.

• Designed to machine stationary workpieces that are difficult or impractical to move.

2. Magnetic Mounting System

• Magnetic base allows the machine to be mounted on suitable ferromagnetic surfaces without welding or bolting the machine directly to the workpiece.

• Provides a convenient installation method for on-site machining applications.

• The stated magnetic holding force is up to 3200 kgf.

• The manufacturer describes the machine as suitable for horizontal, vertical, and inverted mounting, subject to proper installation and safety requirements.

3. Three-Axis Milling Capability

The PIPKM300 features X-, Y-, and Z-axis movement for positioning the milling tool during machining operations.

• X-axis: 300 mm stroke

• Y-axis: 100 mm stroke

• Z-axis: 80 mm stroke

This three-axis arrangement supports small-surface milling and keyway machining according to the workpiece and setup requirements.

4. Precision Dovetail Guideways

The X- and Y-axis feed assemblies use robust dovetail guideways that are precision-ground and hardened. These guideways are designed to support controlled movement, machining accuracy, and long-term service life.

5. Motor-Driven Milling

Powered by a 1.6 HP motor, the PIPKM300 is designed for small-surface milling and keyway machining tasks. The source specifies a maximum cutting depth of 2 mm; actual cutting conditions depend on the workpiece material, tool, and machine setup.

6. Optional V-Mounting Base for Shaft Machining

An optional V-mounting base enables the PIPKM300 to accommodate suitable shaft-type workpieces. This configuration can be used for tasks such as:

• Cutting new keyways on shafts

• Repairing worn keyways

• On-site shaft maintenance

• Small-scale machining and repair work

This option expands the machine's versatility beyond flat-surface milling.
