PEG RS 993 – Boring Machine for Engine Valve Seats and Guides
PEG RS 993 cutting machine for guides and valve seats is specifically designed for processing engines of every size.
DESCRIPTION
During the design of the PEG RS 993, PEG technicians let themselves be inspired by the indications provided by the most expert engine rebuilders, to create a machine that would meet the needs of the modern engine workshops.
The basic concept that led to the creation of the PEG RS 993 valve seat grinding was to create a solid, simple and robust machine that would allow the milling of the seats and valve guides in an extremely precise and rapid way to meet the needs of the most demanding engine rebuilders.
It was therefore decided to minimize the use of electronic components, to ensure greater reliability of the machine and ensure extreme ease of use by the operator.
A complete standard equipment makes the PEG RS 993 valve seats machine the ideal product to restore the seats and valve guides of the engine heads to their original efficiency, whether they are diesel or petrol engines.
SPINDLE – PILOT ALIGNMENT
The movement of the head of the RS 993 in the 4 directions takes place very easily on the upper surface adjusted by the effect of the air cushion, allows rapid positioning of the machine head above the valve seat to be rectified.
The boring spindle is mounted on a spherical system which, when operated floats freely on the air cushion and can tilt ± 7º in any direction, aligning itself autonomously with the pilot’s axis.
The combined action of the head and boring spindle allows a rapid and precise alignment of the spindle on the pilot’s axis.
The air flows that drive the movement of the head and boring spindle are activated through the pedals, thus leaving the operator’s hands free to be able to align the spindle with the pilot.
FASTENING THE ENGINE HEAD
The engine head is fixed to the 2 electromagnetic action support brackets that can be easily moved on the lower ground plane, again due to the air cushion effect.
Once the head is placed in the correct position, the 2 support brackets can be firmly locked to the support surface thanks to the electromagnetic anchor.
TOOL ROTATION
The spindle rotation takes place thanks to a DC direct current motor placed directly in axis, which allows the regulation of the revolutions from 0 to 1000 RPM, by means of a variator.
The 3-corner shaped tool can operate on valve seats of any material, performing the finishing of the entire seat profile in a single process, thus favoring a significant time saving to the operator.
