Wave-form Drill Rod CNC Whirling Solution

What is Drill Rod

Usage: Corrugated thread brazing rod is the core tool of rock drilling blasting and anchoring support, transmitting the impact torque of rock drill, and is used in mine tunneling and stope blasting operations. PH50-1000 is responsible for its precision threading process, which is a key guarantee of product quality.
Material/geometric characteristics: The material of the brazing rod is high-strength alloy steel (HRC30-35), the structure includes complex external corrugated threaded surfaces, and the size requirements: length ≤700mm, diameter 15-80mm, tolerance ±0.02mm.
Common risks: traditional processing is prone to deformation (15% scrap rate), insufficient thread accuracy (20% defect rate), surface burns; The traditional process has low efficiency (30 pieces in a single shift) and cannot meet the needs of large quantities in mines.

Wave-form Drill Rod CNC Whirling Core Pain Point

Pain point 1: Serious processing deformation

• Efficiency: 20% longer production cycle (from 2h/piece to 2.4h/piece)
• Cost: The rework cost increases by 100 yuan/piece
• Quality: 15% scrap rate

Pain point 2: Insufficient thread accuracy

• Efficiency: 30% increase in inspection time (from 10 min/piece to 13 min/piece)
• Cost: The cost of manual adjustment increases by 50 yuan/piece
• Quality: 20% defective rate

Pain point 3: low processing efficiency

• Efficiency: The production capacity of a single shift is only 30 pieces, which cannot meet the demand for orders
• Cost: Low equipment utilization and 15% increase in unit energy consumption
• Quality: Tool wear due to long machining, surface roughness Ra≥12.5

Wave-form Drill Rod CNC Whirling Process

Complete link: blank preparation→ roughing→ cyclone milling finishing (core: PH50-1000), →surface treatment→ quality inspection
Core link: PH50-1000 is responsible for the precision machining of corrugated threads, connecting roughing and surface treatment to ensure the dimensional accuracy of the threads; Each link needs to strictly control the parameters, such as the hardness of the blank tempering and tempering HRC30-35, and the cyclone milling speed of 600-1200rpm.
Blank preparation

• Method: Cutting → quenching and tempering
• Parameters: Hardness HRC30-35, length tolerance ±1mm
• Risk: Uneven material → control: Flaw detection and detection
• Equipment: sawing machine, tempering furnace
  Rough processing
• Method: Turn the outer circle to a dimensional tolerance of ±0.5mm
• Parameters: rotation speed 500-800rpm, feed 0.2mm/r
• Risk: Uneven margins→ Control: Accurate measurements
• Equipment: Ordinary lathe
  Cyclone Milling Finishing (PH50-1000 Core Link)
• Method: C-axis rotating workpiece + cyclone milling head cutting waveform threads at high speed
• Parameters: spindle speed 0-1500rpm, cyclone milling head speed 600-1200rpm, X/Z feed 0.1mm/r
• Risk: Thread burn → Control: Blowing chip evacuation + cooling of the cutting fluid
• Equipment: PH50-1000 CNC cyclone milling machine
  Surface treatment
• Method: Sandblasting → anti-rust coating
• Parameters: Blasting pressure 0.5MPa, coating thickness 10μm
• Risk: Surface damage → Control: Adjust the blasting distance
• Equipment: Sandblasting equipment
  Quality inspection
• Method: CMM → thread gauge inspection
• Parameters: Accuracy≤±0.015mm, Surface Roughness Ra≤6.3
• Risk: Missed detection→ Control: Full inspection
• Equipment: CMM
