What are the key differences between the C and CM models in this series?

The C models (HD-VL1250C / HD-VL1600C) are heavy-duty turning centers optimized for large-diameter turning operations. The CM models (HD-VL1250CM / HD-VL1600CM) are turn-mill centers equipped with live tooling capability (BT50 spindle) and dynamic table C-axis indexing for multi-process turning and milling in a single setup.

What workpiece sizes and maximum weight capacity can these machines handle?

HD-VL1250C/CM: Max turning diameter of 1,250 mm, max workpiece height of 1,000 mm, and table load capacity up to 5,000 kg. HD-VL1600C/CM: Max turning diameter of 1,600 mm, max workpiece height of 1,000 mm, and table load capacity up to 8,000 kg.

How does the movable crossbeam mechanism improve machining accuracy?

The crossbeam features a step-positioning design (200 mm pitch across 4 stages) driven by a worm gear and ball screw. This allows the crossbeam height to adjust dynamically according to workpiece dimensions, ensuring the shortest possible ram extension during cutting, which maximizes rigidity and cutting precision.

What worktable bearing options are available, and how do they handle heavy-duty cutting?

The worktable offers two bearing configurations: high-precision double-row cylindrical roller bearings paired with thrust ball bearings, or high-precision cross roller bearings. Both options effectively absorb combined radial-axial loads and suppress thermal deformation, maintaining high rotational accuracy during prolonged, heavy-duty turning.

What guideway structures are used for the X and Z axes?

The horizontal X-axis crossbeam utilizes a hybrid/linear guideway design for low friction and rapid response. The vertical Z-axis ram features a four-sided enclosed alloy box-way with plastic lamination, delivering exceptional vibration damping and rigidityideal for deep, heavy cutting with extended ram reach.

What drive options are available for C-axis indexing on the turn-mill (CM) models?

Milling models offer two worktable indexing options: a high-precision servo motor drive for accurate part indexing, or a dual-spindle motor drive structure that boosts table torque (up to 20 kNm), eliminates gear backlash, and provides superior indexing accuracy for complex multi-face machining.

What tool magazine options and automatic tool changer (ATC) interfaces are supported?

The machine supports an optional 8-station or 12-station tool magazine. The square forged steel ram integrates an automatic BT50 broaching spindle mechanism for secure tool clamping, fast tool changes, and high repeatability.

Types of Turning Center Series CNC Vertical Lathe

This area can be fully edited and gives you the opportunity to introduce yourself.

Machining Application

Widely used for high-precision turning of rotary parts in machinery processing industries, including automotive, bearings, wind power, aerospace, shipbuilding and others. Designed for processing ferrous and non-ferrous metal parts, it can meet the processing requirements of various industries. Its excellent cost-performance ratio makes it an ideal choice for customers at home and abroad.

Key Components

Machine Structure
The machine features a floor-mounted, thermally symmetrical layout. All major structural components are made of high-strength cast iron, properly annealed to relieve internal stress, ensuring high rigidity and stable accuracy. Key castings are optimized via finite element analysis (FEA) with rational rib arrangement to fully meet high-torque cutting requirements.
Worktable
The worktable offers two structural bearing options: high-precision rolling guideways combined with double-row cylindrical roller and thrust ball bearings for high load capacity and extended service life, or cross roller bearings designed to withstand complex axial-radial loads with superior rotational accuracy.
Ram
The ram is a large-section square forged steel structure, integrated with a turning or turn-mill broaching spindle, enabling automatic tool clamping and release. The ram is precision-ground and heat-treated for superior wear resistance and rigidity. Its closed assembly with the saddle delivers high rigidity for heavy cutting and high machining accuracy.
Tool Magazine
The machine can be equipped with an optional multi-station tool magazine. The ram integrates a BT-type broaching spindle automatic tool changer, improving automation, reliability and tool change accuracy.
