Main Advantages of the CNC Lathe CK350x500

The CK350x500 CNC Lathe combines compact dimensions with advanced technology, making it the perfect choice for companies seeking precise and productive metal-cutting solutions. With its rigid structure, modern CNC control and flexible configuration options, the machine meets the demands of both series and single-part production. High spindle speed, precise feeds and a 12-position turret head enable complex operations with minimal downtime. Below are the key benefits of using this lathe:

• High machining accuracy: A turning diameter over bed of 360 mm and over carriage of 180 mm allow precise processing of various shapes with repeatable results.
• Compact dimensions: Measuring 3020 × 1650 × 1700 mm and with a maximum workpiece length of 500 mm, this lathe is ideal for smaller workshops with limited space.
• High productivity: Spindle speeds ranging from 200–4000 rpm and maximum feed rates of 10,000/8,000 mm/min (Z/X) reduce cycle times and increase output.
• Advanced automation: The 12-position turret head enables quick tool changes, optimising machining processes for complex operations.
• Intuitive control: Standard Siemens Sinumerik 808D control with optional upgrade to Sinumerik 828D or Fanuc Oi-TF provides easy programming and operation.
• Rigid construction: The machine’s 3,200 kg mass and solid bed guarantee stability during machining, minimising vibration and improving surface finish quality.
• Versatile applications: Suitable for threading, grooving, drilling and profile machining thanks to advanced CNC control capabilities.
• Cost-efficient operation: Automatic lubrication and cooling systems reduce maintenance costs and extend machine life.
• Safety and ergonomics: 24 V halogen lighting and an intuitive operator interface enhance working comfort and safety.
• Flexible configuration: Optional equipment such as driven tools or chip conveyors allow the machine to be adapted to specific production needs.

Construction and Technology

The CNC Metal Lathe CORMAK CK350x500 has been designed for precision, durability and efficiency in a compact form. Its key components ensure reliability and high-quality machining:

• Rigid bed: A stable structure weighing 3,200 kg minimises vibration to maintain accuracy even under heavy cutting conditions.
• Large spindle bore: A through-hole of 52 mm allows machining of various bars and tubes.
• Powerful motor: A 7.5 kW spindle motor delivers high performance when machining materials such as steel, aluminium and cast iron.
• 12-position turret head: Holds tools of 12 × 25 mm, enabling fast tool changes and greater automation.
• 3-jaw hydraulic chuck: A 210 mm chuck ensures secure clamping and stable machining of workpieces.
• Automatic lubrication system: Minimises friction in gears and guides, extending component lifespan.
• Cooling system: Maintains optimal cutting conditions, improving surface finish and tool life.
• Tailstock: Equipped with a 62 mm quill, 80 mm stroke and MT4 taper for stable workpiece support and greater precision.

Precision and Efficiency

The Industrial CNC Lathe CORMAK CK350x500 stands out for its high precision thanks to the advanced Siemens Sinumerik 808D control and optional Sinumerik 828D and Fanuc Oi-TF systems. These enable easy programming of complex operations such as threading, grooving and drilling. High feed speeds in the Z/X axes (10,000/8,000 mm/min) and a wide spindle speed range (200–4000 rpm) ensure accuracy and repeatability. The compact design and powerful 7.5 kW motor enable efficient operation with minimal energy consumption — essential in both serial and single-part production processes.
