Application of TLS Servo Control System in Drilling and Tapping Center

01  Industry Background

Drilling and tapping center is a machine tool for metal cutting, which is often designed with machining processes like milling, drilling and tapping. The machine took occupies a small space, and its machining travel and milling load are less than traditional vertical machining center. At present, drilling and tapping center is mainly applied in 3C and new energy field, and the machining materials are mostly aluminum.

02  User Demand

A client from Southern China makes use of T6 drilling and tapping center for the processing of charging pile accessories. To deliver massive orders, the client raised the following requirements: enhancing processing efficiency, guaranteeing processing quality, eliminating the grooves of side tools, providing all-round after-sales services, and ensuring long-term stable system operation, etc.

03  Solution

  1. Overview

Based on nearly 10 years of technical accumulation and rich research, development and application experience in CNC machine tools, our TLS Servo Control System takes high cost-effectiveness, considerate services, and a complete set of automation solution as its selling points. Moreover, our TLS Servo team proposed a complete set of T6 drilling and tapping center servo control solution to optimize machining process and enhance machining efficiency based on the characteristics of machining center.

  1. Features

Onsite testing proves that this solution enhances processing efficiency and processing quality. Meanwhile, as domestically manufactured equipment is utilized, the whole machine’s overall costs are greatly reduced.

 

TLS Servo System Solution is featured by:

※Mature bus technology

——Utilizing mature EtherCAT bus technology

——Ensuring the synchronization of multi-axis control

 

※High-speed main shaft

——Main motor has a maximum rotational speed of 24000rpm

 

※Excellent acceleration and deceleration performance

——The acceleration (0-48m/min) of feed axis increases by 1G

 

※Unique acceleration and deceleration performance

——At top speed, the acceleration and deceleration time (0-20000rpm) is less than 1s

 

※Rotatory ARY signal processing technology

——Unique rotatory variable signal processing technology, and main shaft speed fluctuation for 20000rpm is less than 4rpm

 

※Rigid tapping

——At most 6000rpm rigid tapping for M3/M4 screw thread

 

At the same time, due to the new design in environmental adaptation, the reliability of TLS servo driver is enhanced in the oil stains, dusty, hot and humid environment; the servo motor of IP67 protection level helps to avoid the damage to the motor resulting from dusts or spraying liquids on the client’s factory, making sure long-term stable operation of the System in harsh environments.

04   Application Effects

Backed up by the optimized process and technical support of our TLS Servo team, the T6 drilling and tapping machine tools equipped with TLS Servo Control System increases the processing efficiency by about 25%. Its processing quality is even superior to that of machine tools with imported servo control system.
