The PTR hydraulic pressure tester or test bench allows for the quick and easy detection of fissures and cracks and the water tightness control in the cooling circuits of cylinder heads and engine blocks.

The pressure tester works following a basic principle that consists of plugging all the outlets of the cooling circuit of the cylinder head using rubber stoppers and then injecting pressurized air into the circuit. The cylinder head is then immersed in a hot-water bath and if it contains any cracks or fissures, a stream of air bubbles will be observed rising to the surface of the bath.

The machine has been specially designed for continuous use and is comfortable and simple to operate. Furthermore, the machine requires a minimum amount of maintenance and comes fully equipped with high quality, in-built security features.

The pressure tester is fitted with a programmable heater which allows the water to be preheated on a daily basis.The temperature of the water is regulated by means of an electronic thermostat control.

Hydraulic arms move the cradle holding the piece to be tested. The cradle is moved vertically by means of a hydraulic system. The cradle can also rotate a full 360 degrees making it far easier to check all sides of the cylinder head from every angle.

The water tank and lid are both thermally insulated thus preventing heat loss and substantially reducing operational costs of the machine.The water is heated by means of two 4.5kW elements.The machine is fitted with a safety mechanism that controls the level of the water.

In order to avoid possible injury and unnecessary risks, the operating circuit of the machine is 24 V low voltage.

With two spindle speeds in its head, it is suitable for resurfacing aluminium, cast iron and also alu /pre-chambers cylinder heads. Machine has automatic feed of wheelhead in horizontal movement and manual in vertical movement. Rugged cast iron base and work head with precision guides assures accurate machining of heads and blocks. Cast iron tablet columns and precision spindle bearings along with all our other features make the SG330 an industry best value. The distinctive working system where the head feeds and the table stands, offers an high working precision, reducing the overall dimensions. The range of 4 - 6 cylinder car engines can be covered with this machine. The machine is supplied completely with all its parts: - 330 mm grinding wheel with segments and tools - pair of parallel supports - steel sheet base - coolant system - splash guard - wheel dresser with diamond

Excellent machine for line boring blocks or heads.

The HBM 810 Horizontal Boring Machine is suitable for reconditioning camshaft housing holes on medium size blocks.
Very precise size control and surface finish eliminates line honing all together.

The centering of boring holes is achieved on the boring rod by means of suitable center squares and by a tool holder slide adjustable in height.

The rod is held by 3 supports and it is operated by a head equipped with D.C. engine, which permits to adjust, with a continuous revolutions variation, the rotation and feed speed of the rod.

Fast and accurate are hall marks of this great line boring machine.
