COMEC RP1000 Cylinder Head and Block Resurfacer

The RP1000 is a resurfacing machine for cylinder heads and blocks of cars and trucks, as well as for all flat surfaces requiring a finished and accurate mating surface.
All machine parts, like the base, the table, the column and the head are made of widely ribbed cast iron of the best quality, thereby offering highly rigid and sturdy features.
The table feed is operated through a recirculating-ball screw that is extremely precise even at slow feed speeds. A frequency inverter controlling the screw is attached to the motoreducer to offer different speed feed that can be widely adjusted with a potentiometer.
Another inverter adjusts the spindle speed, in order to get the ideal cutting speed at all times and according to the different cutting systems, like abrasive sectors for the grinding of cast iron or aluminium cylinder heads with pre-chambers, the tool for aluminium resurfacing or the CBN-PCD toolholder plate for high-speed resurfacing.
A conveniently located digital display shows the rotation speed.
For an easy and safe use of the machine, all control commands are located on a rotating control panel that can be adjusted to every operator. Moreover, in order to supply an efficient product, the machine's standard equipment includes the rapid movement of the head, an efficient cooling system complete with a settling tank, and a wheel dressing assembly with diamond dresser.
Useful accessories are also available upon request, such as the adjustable set-up  fixture for cylinder heads, the V-block mounting kit, the rotating backing pad for the grinding of flywheels, clutch friction plates or brake discs.
