Description

 Deep hole drilling and boring machine

T2180   

T2180  deep hole drilling and boring machine is a special machine for machining cylindrical deep holes. It is suitable for drilling and boring of cylindrical deep hole workpieces. It can also meet the functions of trepanning and burnishing, and can work stepped holes machining. The processing aperture precision can reach IT7~IT8 grade, and the surface roughness can reach Ra0.8-0.4μm. At the same time, we can take advantage of the design and manufacture of our company's tools and accessories, and match with the machine tool to meet the deep hole processing needs of various users. This machine is mainly for large-scale deep hole machining in various industries such as hydraulic cylinders, large pipe molds, offshore drilling platforms, and large motor spindle hole machining.

Basic process performance of the machine:

1) The machine can complete the drilling, boring, expanding, burnishsing and trepanning processing functions of the inner hole.

2) During machining, the workpiece rotates and the tool feeds. The cutting fluid enters the cutting zone through the pressure head, cooling, lubricating the cutting zone and taking away the chips.

3) The method of chip removal in BTA is used when drilling. When boring, the process of cutting fluid and discharging chips in the boring tube for cutting fluid forward (bed end) is adopted.

4) According to the user's needs, the machine can be equipped with a  boring box, the workpiece can be rotated at a low speed, and the tool rotates at a high speed to improve the processing efficiency.

5) Machining accuracy of machine tools:

When rough: The aperture accuracy is IT9-10. Surface roughness: Ra6.3.

Fine precision: aperture accuracy IT8-9. Surface roughness: Ra3.2.

When rolling: The aperture accuracy is IT8-9. Surface roughness: Ra0.2.

Straightness of the machined hole: less than 0.15/1000mm.

The exit deflection of the machined hole: less than 0.5/1000mm.

7) Machine tool processing efficiency:

Cutting speed: determined according to the tool structure, material and workpiece material, generally 50-100m/min.

Feeding speed: determined according to the condition of the workpiece and the process conditions, generally 10-100mm/min.

Maximum machining allowance at the time of boring: determined according to the tool structure, material and workpiece, generally not more than 30mm
