How to Troubleshoot Chip-Removal Issues on a Scraping and Burnishing Machine

Release time:

2016-12-13

The honing and burnishing machine is a high-precision, high-efficiency, and highly automated deep-hole machining tool. When used in conjunction with advanced deep-hole drilling tools such as gun drills, BTA drills, and jet-suction drills, it can achieve the surface finish and dimensional accuracy that would normally require multiple operations—drilling, reaming, and broaching—on conventional machine tools, all in a single continuous cutting pass. Next, we will walk you through how to troubleshoot and resolve chip-removal problems that may arise when operating a honing and burnishing machine.

How to Troubleshoot Chip-Removal Issues on a Scraping and Burnishing Machine

During operation, the scraping and burnishing machine may experience poor chip evacuation. To address this issue, adjust the lubricant-to-water mixing ratio, increase the coolant flow rate, and regulate the fluid pressure; however, after closing the mixing valve, ensure that the hydraulic line pressure is maintained within the range of 2.5 to 3.1 MPa. After replacing the cutting tool, inspect the cutting conditions and make appropriate adjustments to the cutting parameters. Subsequently, check whether the tool exit holes on the scraping and burnishing machine are blocked; if necessary, regrind the tool. Also, verify the gas pressure, keeping the lower limit below 5 kg/cm² and increasing it for holes smaller than 10 mm.

Advantages of Scraping and Burnishing Machines Manufactured by Dezhou Boao Machinery

The scraping and burnishing machine, also known as a boring-and-rolling machine or hydraulic-cylinder scraping-and-burnishing machine, is manufactured by Dezhou Boao Machinery using advanced European composite boring-and-rolling technology. A single reciprocating cycle completes both boring and rolling operations, achieving machining accuracy up to IT8 and surface roughness as low as RA 0.05–0.2 μm. It is primarily used for the precision finishing of internal bores in hydraulic cylinders. Compared with conventional honing machines, this equipment offers significant advantages, including lower noise levels, reduced environmental pollution, lower labor costs, and higher processing efficiency. Boao Machinery’s latest-generation scraping-and-burnishing machine delivers 20 times the productivity of traditional deep-hole drilling and boring centers, while maintaining stable performance and intelligent operation.
