AC170 – Cylinder Boring Machine
The Comec AC170 Cylinder Boring Machine is an excellent solution for the precise reconditioning of engine block cylinders, ideal for both car and truck engines. Designed to handle a wide range of diameters from 35 to 170 mm, this machine stands out for its exceptional quality, precision, and versatility, making it the preferred choice of engine rebuilding specialists.
DESCRIPTION
What makes the Comec AC170 truly distinctive is the combination of a proven mechanical structure with modern technical innovations. This combination ensures a superior finish and unique accuracy. A key feature of the Comec AC170 is its quick cylinder centering system, equipped with a touch probe on the boring bar. This system allows the cylinder to be aligned quickly and accurately, significantly reducing set-up time and increasing efficiency.
The machine is equipped with a centesimal dial gauge, providing the operator with highly accurate control over the centering process. This precision is essential to ensure that the cylinder is perfectly aligned before the boring operation, delivering a perfect finish every time. The variable spindle speed, which ranges from 75 to 700 rpm, allows for an adaptable and optimal machining process, suited to the material and size of the engine cylinder. This level of adjustability ensures a high-quality finish every time, regardless of the cylinder specs.
Another important aspect of the Comec AC170 is the depth control system. By using a dial indicator to regulate the boring depth, operators can achieve accurate and consistent results, which is essential for maintaining the integrity of the engine block during reconditioning. The ergonomic design of the machine’s control panel further enhances operator efficiency. All controls are easily accessible, and spindle speed can be adjusted via a potentiometer and monitored through a digital display, ensuring smooth and accurate operation.
The Comec AC170 also features an adjustable boring head feed with upper and lower limit switches, allowing the boring process to run smoothly and in a controlled manner. This adjustability enables the machine to easily handle different job requirements, delivering a consistently accurate bore. The handwheels for longitudinal and cross table movement, together with the locking lever, provide stable positioning, ensuring that the workpiece is held securely in place during the machining process.
The Comec AC170 is undoubtedly a top-of-the-range cylinder boring machine, designed for professionals seeking precision, efficiency, and versatility. Its innovative features, combined with a proven mechanical design, make it an essential machine for any engine rebuilding workshop, providing consistent, high-quality results with every use.
