Dotting Machine Introduction

A dotting machine, also known as a continuous dotting machine or distance gauge, is primarily used to mark round steel, flat steel, steel pipes, steel sections, and non-ferrous metals for use in tensile testing.
This equipment meets stringent technical requirements. Each rotation produces 30 or 40 marking points, with a fixed dotting distance of 10 mm/m and an allowable error of no more than ±0.15 mm/m. The dotting tip is available in 300 mm/m and 400 mm lengths and is made of ball bearing steel with a hardness of at least RC55.
Usage is simple: place the specimen into the specimen holder slot and adjust the nut according to the length of the specimen to accommodate different specimen sizes. Loosen the specimen holder's fixing screws, move the specimen holder back and forth, align the center diameter, and crank it with your left hand. Pull the handle down until it contacts the specimen, and then crank the handle with your right hand to complete the dotting.
The dotting machine is equipped with readily wearable components, such as a dotting drill, roller frame, roller, and spring. During use, ensure that both columns and the punch are lubricated to avoid damaging the punch tip to ensure accurate marking.
The dotting mechanism features a precise construction, easy operation, high efficiency, accurate marking, and ease of inspection and maintenance. The dual-purpose dotting gauge offers two operating methods: first, mark the 10mm mark, then adjust the screw handle to move the specimen 5mm as needed, and then print again to complete the 5mm mark interval.
