The XY-2 core drilling rig is a standardized mechanical spindle rig engineered for shallow to medium-depth exploration. It is heavily utilized for mineral prospecting, hydrogeological surveys, and water well drilling. This machine features an optimized hydraulic feed system that improves drilling efficiency.
Procurement managers must carefully evaluate technical parameters before initiating an RFQ. Different manufacturers offer distinct mounting setups, winch capacities, and mud pump combinations. Understanding these variables ensures the procured equipment aligns with field operational demands.
Industrial equipment sourcing requires a strict focus on OEM capabilities and factory compliance. Buyers must assess production capacity alongside aftermarket support for wear parts. A rigorous supplier evaluation minimizes downtime during remote geological exploration projects.
Why the XY-2 Rig Fits Specific Geological Exploration Scenarios
The XY-2 model bridges the gap between lightweight portable rigs and heavy-duty exploration machines. Its compact spindle design allows for rapid deployment in rugged mountainous terrains. The hydraulic vertical feed mechanism supports a stroke length of 600mm.
This stroke length ensures consistent downward pressure on diamond or tungsten carbide core bits. In hard rock formations, maintaining steady torque is critical for high core recovery rates. Steady pressure prevents the glazing of the diamond matrix on the drill bit.
The rig delivers a maximum spindle torque of approximately 2900 N·m. Its eight-speed transmission provides sufficient flexibility to adapt to varying rock densities. This mechanical adaptability prevents engine fatigue during prolonged exploration drilling operations.
Technical Specifications and Performance Evaluation
Engineers must verify specific performance data to match exact geotechnical requirements. Standard factory configurations rely on a 22 kW electric motor or a 30 kW diesel engine. For remote off-grid drilling operations, diesel power units are absolutely mandatory.
The rig utilizes a twin-gear oil pump for the hydraulic system. This setup consumes less power while maintaining a lower operating temperature. Efficient hydraulics directly extend the lifespan of internal sealing components.
Key baseline specifications include:
- Maximum Drilling Depth: 350m to 600m, strictly dependent on drill rod diameter.
- Spindle Speeds (Forward): Offers eight gears ranging from 65 to 1172 r/min.
- Maximum Hoisting Force: 30 kN capacity to handle heavy drill strings.
- Base Weight: Approximately 950 kg when excluding the power unit.
- Winch Wire Diameter: Standardized at 14mm to sustain high tensile loads.
| Specification | Parameter Value | Engineering Impact |
| Max Drilling Depth | 350m – 600m | Determines the maximum geological exploration target depth. |
| Spindle Stroke | 600mm | Reduces rod lifting frequency and prevents bit burning. |
| Max Torque | 2900 N·m | Enables penetration through dense basalt and granite layers. |
| Winch Capacity | 30 kN | Dictates the maximum drill string weight safety limit. |
When issuing an RFQ, buyers must specify the desired drill rod dimensions. Standard rod diameters of 42mm, 50mm, or 73mm directly impact the achievable depth. Proper specification prevents costly mismatches upon equipment delivery.
Primary Application Scenarios for Spindle Core Drills
The versatility of this rig makes it a staple in multiple geotechnical sectors. Mineral exploration heavily relies on this rig for extracting intact solid core samples. These physical samples are critical for accurate laboratory assays and resource estimation.
Hydrological engineering utilizes the XY-2 rig for large-diameter water well drilling. The machine easily handles the torque required to ream wider boreholes. Furthermore, civil engineering contractors deploy it for high-rise building foundation testing.
The equipment seamlessly transitions between soft soil sampling and hard rock coring. Operators can switch out cutting tools and adjust spindle speeds accordingly. This flexibility maximizes the return on investment for drilling contractors.
How to Source a Fully Hydraulic Coring Drilling Rig
Sourcing industrial drilling equipment requires evaluating a factory’s true manufacturing capabilities. Buyers should look for suppliers offering extensive customization and in-house engineering support. A reliable OEM will provide various mobility configurations to suit different project terrains.
For instance, Shandong Wanli Construction Machinery Co., Ltd. produces diverse coring drilling rigs. Their catalog includes full hydraulic core drilling rigs and oil cylinder lifting models. Partnering with established factories ensures access to genuine spare parts and technical support.
Custom mounting configurations are a major factor during the initial sourcing phase. Buyers can request skid-mounted frames for stationary setups on flat ground. Alternatively, crawler-mounted chassis configurations significantly reduce setup times across uneven worksites.
Selecting the right mud pump integration is equally important for site performance. The rig is often paired with a BW250 mud pump to flush rock cuttings. Proper slurry circulation cools the drill bit and stabilizes the borehole walls.
B2B Procurement: MOQ, Lead Times, and RFQ Workflow
For international B2B procurement, the minimum order quantity (MOQ) is typically one unit. However, purchasing multiple rigs yields better wholesale pricing and optimized shipping logistics. A standard 20-foot shipping container can generally accommodate one fully dismantled unit.
Standard production lead times range from 15 to 35 days for basic configurations. If a customized crawler-mounted chassis is required, assembly times will inevitably increase. It is crucial to outline exact terrain requirements during the initial inquiry.
A professional RFQ workflow accelerates the supplier evaluation process. Procurement managers should provide detailed project scopes to receive accurate quotations.
An effective B2B RFQ should include:
- Target drilling depth and anticipated regional rock hardness.
- Preferred power unit (diesel vs. electric) and local emission compliance standards.
- Mobility mounting preference (skid frame, steel crawler, or wheeled trailer).
- Required quality compliance certifications, such as ISO 9001 or CE marks.
- Expected destination seaport for accurate CIF or FOB pricing calculations.
In large-volume procurement, requesting a factory audit is a standard industry practice. Third-party testing agencies can verify the load capacity of the hoisting winch. Rigorous preshipment inspections prevent functional failures upon deployment to remote mining sites.
FAQ
What is the maximum core drilling depth of the XY-2 rig?
The standard drilling depth ranges from 350m to 600m. This maximum depth strictly depends on the selected drill rod diameter and geological conditions.
Can the manufacturer customize the mobility chassis for rough terrain?
Yes, reliable OEMs offer custom mounting options for the drill unit. Mounting the rig on a steel crawler base vastly improves site-to-site mobility.
What power unit options are available for this drilling equipment?
Standard configurations include a 22 kW electric motor or a 30 kW diesel engine. Diesel engines are highly recommended for remote exploration sites lacking electrical infrastructure.
What certifications should a drilling rig supplier hold for global trade?
Suppliers should hold ISO 9001 quality management system certifications. For European markets, CE compliance for the electrical and mechanical systems is mandatory.
What is the typical production lead time for a customized core drill?
Standard configurations require about 15 to 30 days to manufacture and test. Heavily customized crawler-mounted rigs may extend the lead time to 45 days.
