Why Can We Always Ensure Excellent Quality

Quality Control

For a long time, Hongtuo has held to the 5S management system and has adhered to the spirit of 6Sigma and Lean Production management philosophies. According to actual conditions, we have formed a set of advanced quality management systems for the production of super abrasive products, including honing tools, diamond and CBN grinding wheels, dicing blades and accessories.

　　For process control, we arrange production plans and control production quantity, as well as the traceability of the partially finished products using a technological process. During production, the staff must complete product quality tests and mutual inspection between processes, as well as cooperating with quality inspectors.

　　To ensure the long term stability and continuous improvement of product quality, we have reinforced quality control and supervision, and enhanced quality awareness and the responsibility of our quality inspectors, workers, shift leaders and workshop managers.

　　1. The team must strictly implement the regulations for technical operations, ensure efficient production, maintain a healthy environment and improve the product quality.

　　2. They must organize the workshop staff so every staff member knows how to operate the technology and propose questions about major quality problems for discussion.

　　3. Staff members must analyze existing quality problems and accidents and relay them onto the related departments.

　　4. Finally, they must undertake the main responsibilities for unqualified products that have been sent to the next production process.

HONING CONDITION SOLUTIONS

1.Stone not cutting, glazed

• Shapen alumina & silicon carbide stone with MAN-700(small grit size) diamond dressers; use LBN-700 dressing stick on all other stones.
• Increase cutting pressure.
• Increase stroking speed.
• Use softer stone ( one with lower hardness number)
• Increase lubricity of honing fluid.

2.Slow stock removal

• increase spindle and stroke RPM
• increase cutting pressure
• use softer stone, one with lower stone hardness number
• use coarser grit stone (one with lower grit number)
• increase lubricity of honing fluid.

3.Poor stone life

• Decrease cutting pressure
• use faster spindle speed
• use harder stone (one with higher hardness number)
• use coarser grit stone ( one with lower grit number)
• increase lubricity of honing fluid.

4.Finish too rough

• decrease cutting pressure
• use finer grit stone (one with higher grit number)
• check the honing oil.
• through true shoes to exact bore diameter.
• For extremely fine finish in soft or exotic materials, use bronze mandrel or bronze shoes.
