Regarding the brand, price, and purchase precautions of second-hand car milling composites

Used car milling composite is a second-hand CNC equipment that integrates turning and milling into one machine tool. Here is some information about it:

1、 Popular brands and models

Ha Ting CONOUEST T42: an American brand with a bar passing capacity of 42mm, a spindle speed of up to 6000rpm, a processing length of 368mm, a processing diameter of 226.3mm, and equipped with a Fanuc 18T system.

Mazak INTEGREX50: a Japanese brand with multi axis linkage function, which can achieve efficient processing of complex parts, good system stability, high processing accuracy, and is widely used in aerospace, precision molds and other fields.

Demage CTX310: A German brand known for its high precision and stability. The machine tool has good rigidity and can adapt to the processing of various materials. It has an advanced CNC system, a user-friendly interface, and easy programming.

2、 Price Range

Mid to low end: Some small and medium-sized domestic brands or second-hand car milling composites with long service life and average precision may cost between 100000 and 300000 yuan.

Mid to high end: Common imported brands or well-known domestic brands, used for about 3-5 years, with good condition and high configuration, generally priced between 300000 and 800000 yuan.

High end: Large, high-precision second-hand car milling composites from high-end imported brands such as Mazak and Demage may cost over 800000 yuan, even exceeding 1.5 million yuan.

3、 Purchase precautions

Equipment inspection: Check whether the appearance of the equipment is deformed, bumped, corroded, etc., whether the internal mechanical structure such as guide rails, screw rods, etc. is worn, whether the electrical components of the electrical system are aged or damaged, whether the control system is normal, whether the accuracy, sound, and temperature of the spindle system are normal, and whether the tool changing action of the tool system is accurate and smooth.

Performance evaluation: Understand the production year and usage duration of the equipment, prioritize selecting well-known brands and equipment with good reputation, and request trial processing to observe whether the processing accuracy, efficiency, etc. meet the requirements.

Data procedures: The seller is required to provide the original factory manual, operation manual, maintenance manual, accuracy inspection report, factory certificate of conformity, etc. of the equipment to ensure that the source of the equipment is legal, and the customs declaration form, tariff payment certificate, and other procedures for imported equipment are complete.

After sales service: Understand market prices, avoid buying at high prices, sign detailed contracts, clarify equipment models, specifications, prices, delivery time, quality standards, after-sales service and other terms, choose sellers who can provide after-sales services such as installation and commissioning, training, and maintenance during the warranty period, and have short repair response time and strong repair capabilities.
