BTA Deep Hole Drilling Machine
Zonap’s BTA Deep Hole Drilling Machine is engineered for industries where depth, diameter, and accuracy are non-negotiable. Built for large-diameter, long-depth drilling, this machine delivers exceptional straightness, superior surface finish, and rock-solid process stability—even in the toughest materials. From oil & gas to critical engineering, aerospace to heavy engineering, this machine is designed to dominate demanding drilling applications. With a high-power spindle, counter-rotation system, and high-pressure coolant technology, Zonap’s BTA machine transforms deep hole drilling into a fast, controlled, and reliable process. Multiple variants are available across different machine sizes and configurations to match varied drilling diameters, depths, and production requirements.

- Automotive: Engine blocks, shafts, transmission parts
- Critical Engineering: Barrels, casings, critical long components
- Heavy Engineering: Large shafts and industrial tubes
- Replace cutting oil/coolant at regular intervals and clean the filtration system to prevent blockage and contamination.
- Check the clearance between guide bush and drill tool (recommended 0.01–0.03 mm). Replace the guide bush when wear is noticed.
- After every shift, clean drilling tools, apply anti-rust oil, and store in a dry, protected area.
- Inspect spindle, feed system, and counter-rotation system for smooth operation.
- Check belts, couplings, and bearings for abnormal noise or vibration.
- Verify coolant pressure and flow to ensure proper chip evacuation.
How to Maintain Deep Hole Drilling Equipment
- Replace cutting oil/coolant at regular intervals and clean the filtration system to prevent blockage and contamination.
- Check the clearance between guide bush and drill tool (recommended 0.01–0.03 mm). Replace the guide bush when wear is noticed.
- After every shift, clean drilling tools, apply anti-rust oil, and store in a dry, protected area.
- Inspect spindle, feed system, and counter-rotation system for smooth operation.
- Check belts, couplings, and bearings for abnormal noise or vibration.
- Verify coolant pressure and flow to ensure proper chip evacuation.
How to Clean CNC Deep Hole Drilling & Boring Machines
- Clean guideways, slides, and tailstock sleeve surfaces to remove chips, dust, and oil residue.
- Wipe ball screws, lead screws, smooth rods, and levers.
- Clean motor surfaces, electrical cabinets, belt covers, and panels from dust and oil stains.
- Clean coolant pump, filters, and chip conveyor.
- Check oil level in headstock/gearbox and refill up to the marked level.
- Lubricate guideways, slides, and moving parts using recommended oil.
- Apply grease to grease cups and lubrication points.
Regular maintenance and cleaning as per Zonap guidelines ensures longer machine life, higher accuracy, and trouble-free deep hole drilling performance.
