Precision Components

Precision components of advanced machine tools are the most important parts because they ensure accurate machine performance. Advanced components and parts such as rotary tables and high-speed spindles make difficult processing possible. This article will take a look at some of these components and explore their main features and functions

Couplings

A coupling is a precision component e that connects two shafts together at their ends to transmit forces. This mechanical device allows the interaction between two pieces of rotating parts. With couplings, the force can be effectively transmitted and the transmission itself is accurate enough for indexing works.
 

Gears

Gears have several functions. One is to increase the torque from the driving source to the driven equipment. In machinery, the driving source is usually the motor or the spindle. Gears are precision components that help reduce the speed generated by the motor and change the phase of the rotating shafts.
 

Spindle Sleeves

For the spindle sleeves, there are adaptors to permit the application of taper tooling on a machine with a different taper type. A simple adaptor consists of an externally and internally tapered sleeve to allow a small tool to be installed in a machine with a larger bore space.
 

Locknuts

A locknut is a small device that resists the force of loosening under the vibrations and torque strengths. When a machine is working, vibrations and forces within it may loosen the fasteners at the assembly points. Locknuts are important precision components that can prevent the machine from falling apart.
 

What is Precision in the Machine Tool Industry?

A well-coordinated assembly of precision components helps achieve intended working standards and high-quality products manufacture. Below are some precision standards that are used for every high-quality machining procedure.
 


Origins of Precision, Machine Thinking


This video elaborates where the concept 'precision' came from and how it is measured.

Parallelism: it refers to the sides of a product being parallel to each other as designed. Surface parallelism is a tolerance value that controls parallelism between two (or more than two) surfaces or features.

Occlusal Surface: The term occlusal refers to the surface of precision components such as gears that make contact (meshes) with other gears. The precision of these surfaces is important as it affects the performance of the gears directly. Gears with good occlusal surfaces make less noise and vibration and result in less wear during operation.

Indexing Accuracy: Indexing accuracy refers to moving a part to a new position or location quickly and precisely. When operators are indexing a machine part with a modern CNC machine, its new location can be within a few hundredths of a millimeter or even to within a few thousandths of millimeter values.

Gear Contact Rates: Gears are ground separately and there are no 100% identical gear teeth but only acceptable tolerances within the targeted standard. So how to maintain gears within controlled accuracy is an issue that determines the driving force of the corresponding devices.

Repeatability: Repeatability is the proximity of the agreement between the outputs of continual measurements of the same measurement results carried out under the same conditions.
