A catch plate, also known as a driving plate, is a fundamental accessory used primarily on manual lathes. It is a circular disc mounted onto the lathe spindle, featuring slots or a pin designed to engage with a lathe dog. The workpiece is secured by the dog, and as the catch plate rotates, it drives the dog and the workpiece, enabling it to turn between centers. This simple yet effective mechanism is essential for performing operations like turning and threading on cylindrical workpieces, ensuring power is transmitted smoothly and accurately for precise machining.
Its straightforward mechanical construction with no complex parts makes it extremely durable, reliable, and resistant to failure.
It enables accurate turning between lathe centers, ensuring excellent concentricity and producing high-quality, cylindrical workpieces.
As a simple piece of equipment, it is very affordable to purchase and maintain compared to more complex workholding systems like chucks.
