First, the basic process performance of the machine tool:

This machine is a deep-hole equipment specially used for internal hole processing of heavy workpieces. This machine tool can complete the drilling, boring, expanding, rolling, and nesting of inner holes. The boring bar uses cutting fluid to discharge cutting fluid and iron chips to the bedside. According to user requirements, the machine tool can be equipped with a drill (boring) rod box to increase the drilling function. The BTA chip removal process is used for drilling. The workpiece can be rotated at low speed and the tool can be reciprocated at high speed to improve processing efficiency. Zh

Heavy-duty deep-hole boring machine can process the inner hole diameter of the workpiece up to φ800mm, and the length of the workpiece can reach 16m. Zh

Processing accuracy of machine tools:

During rough boring: hole diameter accuracy IT9-10. Surface roughness: Ra6.3. Zh

When fine boring: hole diameter accuracy IT8-9. Surface roughness: Ra3.2. Zh

During rolling: Aperture accuracy IT8-9. Surface roughness: Ra0.4 or more. Zh

Straightness of processed hole: ≦ 0.15 / 1000mm. Zh

Exit deviation of the machined hole: ≦ 0.5 / 1000mm. Zh

Processing efficiency of machine tools:

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

Feed rate: determined according to the conditions of the workpiece and the process, generally 10-100mm / min. Zh

Maximum machining allowance when boring: Determined according to the tool structure, material and workpiece conditions, generally not more than 30mm.
