130mm CNC Pipe Threading Lathe Metal Pipes

The QK1313 CNC pipe threading lathe is engineered for semi-finishing, finishing, drilling, and tapping operations on shaft and disc parts, with specialized capability for pipe thread production. The machine uses a two-axis two-linkage CNC system to support processing of complex shapes. As part of the QK series that also includes QK1319 and QK1322 models, this lathe addresses pipe threading requirements across a diameter range from 30 mm to 220 mm depending on the specific model. Manufactured by Shandong HQ Precision Technology Co., Ltd., a company established in 1952 and former designated pipe thread lathe supplier for the Ministry of National Machinery Industry, the QK series benefits from decades of specialization in pipe threading lathe production. The facility holds ISO9001 certification and maintains over 500 production and precision testing devices.

Core Capabilities of QK1313 Pipe Threading Lathe

Thread Processing Capabilities

The lathe supports metric and imperial straight thread cutting, as well as tapered thread production for both external and internal applications. Pipe threading range for the QK1313 model spans 30-126 mm, while the QK1319 covers 50-193 mm and the QK1322 handles 50-220 mm. This range covers common pipe sizes used in oil and gas, plumbing, and hydraulic systems.

Turning Operations

The machine performs straight line, oblique line, and arc turning, including cylindrical, conical, and spherical surface generation. Applicable workpiece types include discs, sleeves, shafts, and other precision components requiring both turning and threading in a single setup.

Drilling and Tapping

The lathe accommodates axial hole processing and thread tapping operations, expanding its utility for parts requiring both external and internal machining. This capability reduces the need for secondary operations on separate machines.

Structural Design of QK Series Pipe Threading Lathes

Flat Bed Construction

The QK1313 features a one-piece flat bed design that supports convenient operation, smooth chip removal, and efficient workpiece loading and unloading. The flat bed layout provides stability for pipe threading applications where long workpieces require consistent support along their entire length. Guideway width measures 550 mm across all QK series models.

Guideway System

The guide rails undergo intermediate frequency quenching to enhance surface hardness and extend service life. The quenching process improves wear resistance, which is particularly important for pipe threading operations that generate long, continuous chips. Maximum load capacity is rated at 3 tons across all models.

Transmission System

The X-axis and Z-axis employ direct-connected transmission, which contributes to stability and dynamic accuracy during cutting cycles. X-axis rapid traverse rate is 4,000 mm/min, while Z-axis rapid traverse reaches 6,000 mm/min. Direct drive configuration reduces backlash and improves positioning repeatability.

Tool Holder

A four-station electric tool holder comes standard, providing fast tool change capability and support for multiple accessory types. Tool shank size is 32×32 mm across all models. Customized tool holder configurations are available according to customer requirements.

CNC Control System for Pipe Threading Lathes

The lathe uses an AC digital drive with semi-closed loop control. Advanced functions include pitch compensation, constant linear speed cutting, fixed cycle programming, direct programming from drawing dimensions, and DNC communication. Available control system brands include GSK, Fanuc, KND, and Siemens, allowing enterprise customers to select the system that matches their operational preferences and operator training.

Note: Machine bed length can be customized according to real work demand. Machines on this page can be configured with servo motor direct driving structure turning center with C axis.

Industrial Applications of CNC Pipe Threading Lathes

QK series CNC pipe threading lathes serve commercial users across the oil and gas sector, pipeline engineering, hydraulic component manufacturing, and general metalworking industries. These machines produce threaded pipe connections, coupling components, and cylindrical parts requiring both external and internal thread profiles. The customizable bed length — ranging from 1000 mm to 6000 mm — enables the lathe to accommodate various pipe lengths and production scenarios. For facilities requiring additional capability, a servo motor direct driving structure turning center with C-axis is available as an option.
