1.7 Drill box:

Adopt the servo main motor driving the spindle to rotate through synchronous belt and synchronous belt wheel, speed stepless could be realized , The max. speed of main spindle is 5000r/min; the spindle drive is front-loaded, which is good for the protection of the main motor and convenient for tool change.

1.8 Headstock:

Drive the workpiece rotation, the speed is constant 117r/min; the spindle can move axially under the control of the hydraulic system, used for tightening or loosening the workpiece. The spindle drive is front-mounted, which is convenient for loading and unloading workpieces and helps to protect the main motor.

1.9 Cutting tool feeding system:

Adopting the structure of servo motor driving ball screw, the tool feed can realize stepless speed regulation.

1.10 Drill bar support rest : 2sets , Support drill bar .

1.11 Coolant system :

It mainly consists of high-pressure pump group, chain plate chip conveyor, oil cooler, filtering device and so on. On the operation station of the numerical control system, a cooling system flow adjustment panel is assembled.

1.12 The basic parts such as bed body and box body are casted with resin sand and treated with two aging treatments. The inclined design of the oil return groove of the bed will not store oil.

1.13 Guide frame

is used for tool guiding, chip removal, and support of tool bar. The front end is assembled with a guide sleeve for tool guiding; the rear end is assembled with a tool bar support sleeve for supporting the tool bar.

1.14 Protection: Full protection.

11. Machine tool installation and commissioning

11.1 Party B is responsible for providing the appearance drawing of the machine tool.

11.2 After the machine tool arrives at the destination, Party A is responsible for lifting, unloading and storing the product (to avoid loss and rain erosion, etc.).

11.3 Party B receives Party A's notification of installation and commissioning, and arranges the personnel to carry out the installation and adjustment of the machine tool. After Party B arranges the personnel to set the machine tool in position and pre-adjust the level, it will enter the process of installation and commissioning.

11.4 The machine tool installation and commissioning work by Party B to send mechanical, electrical, testing and other aspects of the professional staff to the site of Party A to carry out. Party A shall send relevant personnel to assist in the installation and commissioning work and provide the necessary working conditions.

11.5 Party A needs to prepare the power supply, lifting equipment, auxiliary materials, oil and the necessary tools and gauges in the process of installation and commissioning.

12. Acceptance of machine tools

Acceptance of machine tools is divided into two stages: pre-acceptance, final acceptance, pre-acceptance in Party B's factory, final acceptance in Party A's use of the site.

12.1 After the machine tool is assembled and commissioned at Party B's assembly site, Party B will notify Party A, and Party A should send relevant personnel to Party B's assembly site in time to carry out the pre-acceptance work and process one test piece, and the pre-acceptance standard will be according to the content of the technical program or technical agreement signed between Party A and Party B for acceptance.

If Party A can not provide test pieces, cutting tools, auxiliary tools, then use Party B's standard test pieces, cutting tools, auxiliary tools for pre-acceptance trial processing.

Pre-acceptance is completed, the two sides signed the pre-acceptance minutes.

12.2 Final acceptance of the machine tool refers to the final acceptance of the machine tool after the installation and commissioning of Party A's use of the site. Processing test pieces of 8 pieces, test pieces, cutting tools, auxiliary equipment provided by Party A, the final acceptance criteria in accordance with the A and B signed by the technical program or technical agreement content acceptance; to meet the requirements of the final acceptance is deemed to be qualified, and signed by both parties to the final acceptance of the single. The warranty period of the machine tool will be calculated from the date of signing

the final acceptance form by both parties. If there are any outstanding issues during the final acceptance process, they can be written into the final acceptance memorandum and dealt with by both parties through consultation.

12.3 Only the machine tools signed the final acceptance form, Party A enjoys the right to use, Party B provides warranty, technical support and other follow-up services.

13. After-sales service
