HAIDI TCK Series Slant‑Bed CNC Lathes – 45° Integrated Bed, High Rigidity, and Micron‑Level Precision for High‑Volume Production

Why the 45° slant bed has become the industry standard

In modern CNC turning, the 45° slant‑bed design has become the benchmark for high‑productivity machining. Unlike traditional flat‑bed lathes, the inclined bed orientation offers fundamental advantages that directly impact part quality, tool life, and production efficiency.

The HAIDI TCK series is built around this proven design philosophy. The one‑piece cast iron bed – produced in HAIDI‘s own foundry – is inclined at 45°, creating a structure that combines exceptional rigidity with intelligent chip management.

Efficient chip evacuation – the hidden productivity factor

One of the most significant advantages of the 45° slant bed is chip evacuation. Chips and coolant fall directly into the chip tray under their own weight, rather than accumulating in the cutting zone. This prevents chips from being re‑cut, which can damage the workpiece surface and accelerate tool wear.

For shops running high‑volume production, this translates into longer tool life, better surface finishes, and less time spent cleaning the work area between cycles.

Superior rigidity and vibration damping

The TCK series bed is cast from high‑quality HT300 iron and features a ribbed internal structure designed through finite element analysis. The 45° bed geometry directs cutting forces downward into the machine base, where they are absorbed by the mass of the casting. This provides exceptional rigidity even during heavy roughing cuts, minimising vibration and chatter.

The result is consistent surface finishes and extended tool life – even when machining tough materials like alloy steel and stainless steel.

TCK63E – heavy‑duty turning with box guideway rigidity

The TCK63E is HAIDI‘s flagship heavy‑duty slant‑bed lathe, designed for shops that need to remove large amounts of material while maintaining precision. The machine features HRC55 hardened box guideways, which provide exceptional structural rigidity and vibration resistance, eliminating chatter during high‑torque cuts.

Key specifications of the TCK63E include:

• Maximum swing over bed: 650 mm

• Maximum swing over slide: 470 mm

• Maximum turning diameter: 630 mm

• Center distance: 1,320 mm

• Spindle bore options: 85 mm (A2‑8) or 105 mm (A2‑11)

• Bar capacity: up to 88 mm

• 3‑speed automatic gearbox: 30–150 rpm (low), 100–450 rpm (medium), 400–1,500 rpm (high)

• Spindle motor: 15–18.5 kW

• Maximum torque: up to 1,900 N·m

The TCK63E is particularly well‑suited for processing alloy steel, stainless steel, and cast iron components where heavy material removal and consistent precision are required.

TCK6340S – high‑speed precision with linear guideways

The TCK6340S is designed for high‑speed, high‑precision turning of smaller to medium components. It adopts the same 45° integrated slant‑bed structure but is equipped with high‑precision pre‑loaded Taiwanese linear rolling guideways. This configuration delivers excellent positional accuracy, smooth movement, and rapid traverse speeds – ideal for finishing operations and high‑volume production of smaller parts.

Key specifications of the TCK6340S include:

• Maximum swing over bed: 400 mm

• Maximum swing over cross slide: 140 mm

• Maximum machining length: 300–400 mm

• Spindle nose: A2‑5 (6″ chuck)

• Spindle motor: 3.7 kW

• Spindle speed: up to 4,000 rpm

• Positioning accuracy: ±0.003 mm

• 45° integrated bed with Taiwanese linear guideways

The TCK6340S is ideal for workshops producing small shafts, pins, fittings, and precision components requiring fine surface finishes and tight tolerances.
