The processing of modern mechanical parts, especially the processing of automotive parts, continues to move in the direction of meeting the requirements of high efficiency, high precision, high stability, high volume, and low cost. With the ever-increasing labor costs worldwide, the automation of the processing process is becoming an important way for manufacturing companies to seek “cost reduction and efficiency increase”.

Based on this background, various types of flexible units and flexible production lines composed of robots and machining centers, turning and milling machines, and grinding machines are steadily expanding their application areas. In recent years, this trend has become apparent in the automotive industry. Even if we do not focus on the entire production line, merely looking at this phenomenon from the car processing unit is enough to be able to fully substantiate how the machining process is moving towards automation.

Automatic CNC machining unit The automatic processing unit of SPINNER Machine Tool Manufacturing Co., Ltd. uses standard CNC lathes, together with precision fixtures and automation devices, including advanced robot systems, to form an automated CNC processing unit. While realizing the automation of the processing process, it can also guarantee the advantages of high efficiency, high precision, and high stability of the original machine tool. For its application in the field of automobile manufacturing, two examples were given.

1. Automotive diesel injection parts processing system Each car engine cylinder needs a set of injection devices, so the workpiece must be processed in large quantities, the processing process there are many special requirements, including: the process can not touch the workpiece; High rigidity drilling and rough machining; Fire extinguisher and explosion-proof device installed; Special suction oil mist device; Processing of high density materials; High precision repeatability for subsequent machining fixtures; Reliable process; Central connection Cooling unit; holder for CAPTO interface; 120 bar high pressure cooling for deep hole drills; high surface finish and long tool life; special operator panel for entering values, including control functions and tool monitoring functions to correct fuzzy inputs Flush the high pressure unit of the chuck.

As shown in the figure, the system provided by SPINNER includes a set of turning units (PDs) with attached work stations and a set of SCARA robot units.

2. Injector needle valve body soft processing equipment Injector needle valve body processing for batch precision machining, in the upgrading of products, as well as digital production of processing equipment put forward higher requirements. The SB ultra-precision CNC lathes from Spencer are equipped with self-dropping chutes, automatic flushing systems, small robots and automatic feeders. The automatic injection needle valve body soft processing machine has been proved by practice. It has the features of high processing precision, good stability and quick production cycle. Moreover, its small footprint, easy maintenance and debugging.

Thanks to the machine's advanced CNC system and full closed-loop servo feed system, good accuracy can be maintained, and both flexible programming functions and a complete digital communication interface. At present, these soft processing equipments have been provided to a large number of injector manufacturers in Europe, Asia, and the Americas, and Japan's new product development units.

As mentioned above, the use of commercial robots to form flexible automated processing units is the current trend of automation. Taking engine processing equipment as an example, with the acceleration of new models of vehicle companies, the requirements for flexibility of engine production lines are getting stronger and stronger. Usually, an engine production line needs to be able to meet the requirements of producing at least three models. Of course, although the above mentioned auto parts processing equipment, in fact, for other machine tool user industries such as railway transportation equipment, nuclear energy equipment manufacturing, aerospace, etc., this trend still applies.

1. Off-machine robot automatic processing unit Let's look at the automated processing unit consisting of Spinner's TC-52 Turning Center + robot and see the penetration of automated machining: The robot removes the blank from the off-board hopper and loads it into the machine. On the clamping system of the machine tool, the finished parts are taken out after being processed, and are arranged in the finished box in an orderly manner. During the machining process, the robot can also perform workpiece turning, tool detection, and other work.

2. Side-by-side machine robot automated processing unit In the occasion where the part processing cycle is long, in order to make full use of the robot's performance, one robot may serve two or more machine tools. It is worth mentioning that the parallel processing machine robot robotic processing unit consisting of two machine tools and one robot can cross and complete the loading and unloading of the two machine tools.

3. Ultra-precision robotic machining units for robots Ultra-precise, automated machining units made up of Spinner's ultra-precision CNC machine tools PD/A and mini-in-machine robots are used to perform precision machining of parts with high efficiency, automation, and dexterity. Small robots are mounted inside the machine and are used to complete the loading and unloading of parts and the boring of parts.
