IT6 Slant Bed CNC Lathe Shaft Machining

The CKY series slant bed CNC lathe is a line of metalworking machines designed for processing shaft parts, disc components, and workpieces with complex curved surfaces. Available in five base models — CKY6156, CKY6163, CKY6180, CKY61100, and CKY61125 — this series covers a swing diameter range from 560 mm to 1250 mm, accommodating a broad spectrum of workpiece sizes. The lathe employs a CNC control system paired with a slanted bed structure to support turning operations on various rotational parts. Manufactured by Shandong HQ Precision Technology Co., Ltd., a company established in 1952 and a former designated pipe thread lathe manufacturer for the Ministry of National Machinery Industry, these lathes are produced in a facility holding ISO9001 certification with an annual output of 1,000 units. The company holds 30 patents, including 6 invention patents, and allocates over 5% of annual revenue to research and development.

Key Construction Features of Slant Bed CNC Lathes

Bed and Guideway System

The lathe features a one-piece slant bed cast from high-strength iron, which contributes to structural rigidity and vibration damping during cutting operations. The guideways undergo ultrasonic frequency quenching to enhance surface hardness and wear resistance. Carriage and guideway contact surfaces incorporate Turcite B material to support consistent positioning accuracy over extended operation periods. The slant bed angle is 45 degrees for models CKY6156 through CKY61100, and 60 degrees for the CKY61125, a configuration that facilitates gravity-assisted chip evacuation.

Spindle System

The spindle bore ranges from 80 mm (CKY6156) to 120 mm (CKY61125), with spindle nose configurations from A2-8 up to A2-15. Spindle speed is stepless across all models, with maximum speed decreasing from 1500 rpm (CKY6156) to 630 rpm (CKY61125) as swing diameter increases. Main spindle motor power ranges from 15 kW to 37 kW, scaled to match each model's material removal capacity and torque requirements. Hydraulic chuck sizes range from 12 inches to 32 inches across the series.

Turret and Feed System

Models are equipped with a hydraulic turret offering 12 tool positions, enabling multiple machining operations without manual tool changes. Tool shank size measures 25×25 mm for the CKY6156 and 32×32 mm for larger models. X-axis rapid traverse rate reaches 12,000 mm/min for CKY6156 through CKY6180, and 10,000 mm/min for CKY61100 and CKY61125, all with hard guideways. Z-axis rapid traverse follows the same pattern. Minimum programmable increment for both X and Z axes is 0.001 mm.

Tailstock

The tailstock quill diameter ranges from φ110/120 mm to φ130 mm across the series. Quill taper specifications range from MT5 to MT8, with travel distances from 100 mm to 150 mm depending on the model. The tailstock provides support for long workpieces during turning operations.
