PHM Mobile Honing Machine

Application:

The PHM mobile honing machine allows for the honing of cylinder liners of large diesel engines while they are installed in the crankcase.
The HMB stationary honing machine base is required for honing cylinder liners that have been removed.

Working Range:

Honing diameters up to 640 mm

Features:

The PHM is a stable and robust machine with an excellent adhesive powder coating. The rotational speed and stroke speed of the honing head can be continuously adjusted by regulating the air supply to achieve the desired cross-hatch angle. The contact pressure of the honing stones is also continuously adjustable by regulating the air supply to the pressure cylinders. When the compressed air supply to the pressure cylinders is switched off, the honing stone holders are automatically retracted, preventing unwanted scratch marks when inserting the honing head into the cylinder liner or removing it.
The powerful drive motor for the rotational movement of the honing head allows the speed to be adjusted within a wide range without any gear changes, simply by adjusting the corresponding control knob. The control knobs for regulating the air supply, along with pressure gauges for displaying the set pressure values, are housed in a central control station.
The pressure values once determined and displayed for achieving an optimal honing result can therefore be reset at any time later.

Only three honing heads are required for bores with diameters from 150 to 640 mm.

Honing head 150-250 for honing diameters 150 to 250 mm.
Honing head 240-340 for honing diameters 240 to 340 mm.
Honing head 320-640 for honing diameters 320 to 640 mm.

Each honing head can be adjusted to the required honing diameter using spacers.

The machine is equipped as standard with an automatic stroke system, which enables automatic stroke movement of the honing head with adjustable stroke length, as well as a convenience control where the control station is mounted within reach of the operator standing at the level of the cylinder liner.

A central air treatment unit with filter and oiler ensures trouble-free operation.

The machine is set up quickly in three simple steps:

Place mounting tubes on two opposite studs.
Place the pre-assembled drive unit onto the mounting tubes.
Couple the honing head to the air motor.
