Two-line one-rigid typically refers to the X and Y axes as linear gauges, with the Z axis being the rigid gauge. The three-line system usually indicates that the XYZ guide ways are all linear gauges. The two-line one-rigid configuration is generally suitable for heavy cutting or high-rigidity cutting, and is ideal for processing molds or steel products. The advantage of the three-axis guide way is its high speed and precision, making it suitable for the fine processing of shaped products. The difference between the vertical machining center's linear gauge and rigid gauge:

Vertical Machining Center Hard Rule

When vertical machining centers were first introduced, their guide ways were all made of rigid rails. The process for rigid rails is highly complex, requiring precision finishing on a grinding machine after heat treatment and manual scraping to achieve the final shape. This process has a long production cycle and high technical difficulty, and is now mostly treated with plastic coating. Rigid rails have high friction, inertia, and strength, and are generally defined as heavy cutting and heavy-duty CNC machining centers.

The guideways and beds of the rigid rail machining center are cast integrally into shape, then machined into guideways, and further processed into rigid guideways through quenching and grinding techniques. The rigid guideways offer excellent rigidity and strong load-bearing capacity. However, they differ in precision and speed compared to wire gauges.

Vertical Machining Center Line Specifications Introduction

Vertical machining centers currently predominantly use linear rolling guideways, which offer fast movement speeds, low rolling resistance, no crawling, and easy lubrication. Over extended use, precision loss is also minimal.

Linear guides, also known as "linear guides," are widely used in vertical machining centers. They offer low friction, high responsiveness, and minimal inertia. Assembly involves securing multiple pressure plates to the bed, making installation and adjustment easy. However, their strength is inferior to that of rigid guides, making them unsuitable for heavy-duty machining. Linear guides consist of two parts: the slider and the carriage. The sliders are equipped with recirculating balls or cylinders. The length of the slider can be customized based on the travel distance. The linear guides on vertical machining centers can be disassembled and replaced after wear, restoring their original precision. As rolling friction, they feature high speed, low resistance, and easy lubrication. Current vertical machining center machines commonly use linear guides, enabling high-speed, high-precision linear motion under high-load conditions.
