• Acceptance Express | Acceptance of the Thermal Error Compensation System project of a well-known domestic large machine tool factory

Recently, SIGER Data deployed a "thermal error compensation system" project for a well-known large machine tool factory in Sichuan, China, and successfully passed the customer's acceptance! First of all, I would like to thank the customer for their trust and the hard work of the project team, which enabled the client to quickly apply machine tool thermal error compensation. The core goal of this project is to monitor the temperature changes of the machine tool in real time, accurately calculate and compensate for the impact of thermal deformation on machining accuracy, and ensure that the machine tool maintains high stability under temperature changes, thereby improving the accuracy and consistency of workpiece processing.

1. Customer background introduction:

The customer is an enterprise specializing in the manufacturing of special equipment such as CNC machine tools, non-standard equipment, and automation equipment. The company adheres to the concept of scientific and technological innovation and has an experienced R&D team. It has successfully developed and mastered 21 core independent intellectual property rights, and has passed ISO9001 quality management system certification, ISO14001 environmental management system certification, and weapons and equipment quality management system certification. The company's products are characterized by stable performance, high precision, and good reliability. They are widely used in aerospace, automobile manufacturing, mold processing and other fields, and are deeply trusted and praised by users.

Customer pain points and needs:

1) Processing accuracy is affected by thermal errors, resulting in unstable product quality. Real-time compensation ensures high-precision processing of workpieces.

2) Thermal errors cause machine tool processing efficiency to decrease, increasing production cycles. Real-time compensation improves machine tool operation efficiency.

3) Material waste and rework caused by thermal errors increase production costs. Reducing the scrap rate caused by thermal errors reduces costs.

4) Traditional calibration methods are difficult to achieve high-precision processing requirements. Intelligent thermal error compensation systems meet high standards for precision processing.

2. Project deployment

2.1 Thermal Compensation Management System - Compensation Principle Diagram

Thermal Compensation Management System (Thermal CMS) is a technical solution for improving the machining accuracy of machine tools. It monitors and analyzes the errors caused by temperature changes during the operation of the machine tool, and takes measures to compensate for these errors, ensuring that the machine tool can still maintain high-precision machining performance in an environment with temperature changes. This technology is crucial for precision machining in industries such as aerospace and precision molds.

3.1 Comparison results of X-axis thermal elongation and temperature change test

Before thermal compensation is turned on: X-axis thermal elongation changes by 175μm, spindle motor temperature changes by 11.7℃.

After thermal compensation is turned on: X-axis thermal elongation changes by 50μm, spindle motor temperature changes by 10.9℃.

Application effect: thermal elongation is reduced by 125μm, and the thermal compensation effect can reach 71.42%.

3.2 Comparison results of Y-axis thermal elongation and temperature change test

 

Before thermal compensation is turned on: Y-axis thermal elongation changes by 144μm, and spindle motor temperature changes by 6.1℃.

After thermal compensation is turned on: Y-axis thermal elongation changes by 32μm, and spindle motor temperature changes by 5.2℃.

Application effect: Thermal elongation is reduced by 112μm, and the thermal compensation effect can reach 77.78%.

3.3 Comparison results of Z-axis thermal elongation and temperature change test

Before thermal compensation is turned on: Z-axis thermal elongation changes by 53μm, spindle motor temperature changes by 3.5℃.

After thermal compensation is turned on: Z-axis thermal elongation changes by 12μm, spindle motor temperature changes by 2.2℃.

Application effect: thermal elongation is reduced by 41μm, and the thermal compensation effect can reach 77.36%.

3.4 Project Acceptance Report:

Through the close cooperation between the SIGER project team and the customer project, the SIGER Data team successfully implemented the deployment of the thermal error compensation system. The project successfully passed the customer's acceptance, and the product application effect was highly recognized by the customer. We look forward to providing further services to customers next time. 

 

4. Quickly understand SIGER Thermal Compensation Management System

SIGER Thermal Error Compensation System (Thermal CMS) reduces thermal errors in CNC machine tools caused by temperature variations during machining through measurement and compensation systems, thereby enhancing machining accuracy and stability.
