Tool Clamping The length of the tool shank extending from the tool holder should not exceed 1.5 times the height of the tool shank (except for boring, grooving, etc.). The tool shank axis should be perpendicular or parallel to the feed direction. Adjustment of Tool Tip Height: For turning end faces, conical surfaces, threads, forming…
Before Starting Work Machine Check and Warm-up: Check whether all mechanisms of the lathe are in good condition and whether protective equipment is available. If normal, run the machine at low speed for 1-2 minutes to check if the operation is normal. This also allows the lubricating oil in the headstock to reach the…
Proximity of frequently used items: All items used during work should be placed as close as possible and concentrated around the operator’s area, but without hindering free movement. Frequency of use: Commonly used items should be placed closer, while rarely used items should be placed farther away. Natural movement: The placement of items must conform…
The performance of a lathe includes: machining performance, operational performance, and parameter performance. Machining performance refers to cutting efficiency (whether high-speed cutting is possible to shorten machining time and improve cutting efficiency) and the range of parts that can be machined (whether it can carry out various turning operations, including turning metric threads, inch threads,…

Machine Tool Description 1.1 Main Applications:This series of lathes is suitable for various turning operations, such as turning inner and outer cylindrical surfaces, conical surfaces, other rotary surfaces, and end faces. It can also cut various common threads — including metric, inch, module, and pitch threads — as well as perform drilling, reaming, tapping, and…
The four principles of process sequence arrangement in mechanical manufacturing technology 1. Machining Reference Surfaces First, Then Other Surfaces Why it’s important: The reference surfaces serve as the foundation for aligning and positioning all other features of the part. By machining these first, you ensure that everything else is referenced to a stable, known location….
On a lathe machine, the terms cutting depth (ap), S, and F are the three main cutting parameters you must know. 1. Depth of Cut (ap) Meaning: How deep the tool cuts into the workpiece in one pass. Unit: millimeters (mm). Typical values: Roughing (removing material fast) → 2–5 mm Finishing (for smooth surface) →…
Introduction What is a Lathe Machine? A lathe machine is one of the oldest and most fundamental tools in the world of machining. It is a machine tool that rotates a workpiece around an axis to perform various operations such as cutting, drilling, sanding, knurling, turning, and deformation. With the help of different cutting tools,…
