Cylinder Head & Block Skimming & Resurfacing

The Cylinder Head Shop uses a Comec RP 850 utilising CBN and diamond tooling to achieve a perfect finish on cast iron and aluminium heads for two and four-stroke petrol and diesel motors.

The RP 850 is a resurfacing machine for cylinder heads and blocks of motorcycles, cars and trucks, as well as any other flat surface, which require a high degree of finishing and accuracy.

All parts composing the machine, such as basement, table, column and head, are made of high quality cast iron which is widely well-framed offering high rigidity and sturdiness as a feature.

No movement means more accuracy. Precision skimmed heads and blocks lead to far better performance.

The table feed on the Comec 850 is operated by a ball screw drive with extreme precision, even at slow feed speeds. A frequency inverter controls the ball screw driving moto-reducer, offering a variable speed feed widely adjustable by potentiometer. We are able to produce excellence result every time.
