HAIDI TCK63E Slant‑Bed CNC Lathe – 45° Integrated Bed, 3‑Gear Gearbox, and Heavy‑Duty Box Guideway for High‑Torque Machining

Why 45° slant‑bed design makes a difference

For small to medium workpiece processing, the 45° slant bed CNC lathe offers significant advantages over traditional flat‑bed configurations. The 45° bed slope directs chips and coolant directly into the chip conveyor, preventing chip accumulation on guideways and reducing the risk of re‑cutting. Gravity also assists the smooth movement of heavy components like the turret and tailstock, improving overall rigidity during heavy cutting operations. This is why the 45° slant bed has become the industry standard for heavy‑duty turning applications.

The HAIDI TCK63E takes this proven concept further with a one‑piece cast 45° slant bed structure. The bed has been carefully engineered with finite element analysis, with carefully arranged ribs to maximize structural rigidity while maintaining a compact footprint. The machine occupies approximately 3.7 meters in length and 1.9 meters in width, making it suitable for shops where floor space is limited.

HRC55 hardened box guideway – stability for heavy cuts

Unlike the linear guideways commonly found on entry‑level machines, the TCK63E uses HRC55 induction‑hardened box guideways – a design that prioritizes rigidity and load capacity over ultra‑high speed movement. The box guideway provides a larger contact area between moving surfaces, distributing cutting forces evenly and minimizing deflection during deep roughing passes. The guideway surfaces are induction‑hardened to HRC55, ground to precision tolerances, and coated with Turcite‑B to reduce friction and eliminate low‑speed stick‑slip.

For a shop regularly machining alloy steel or stainless steel components – where cutting forces are high and tool life is directly affected by machine rigidity – the box guideway is a significant advantage. It absorbs cutting vibrations that would otherwise cause chatter marks on finished surfaces.

3‑gear automatic gearbox and spindle system

One of the defining features of the TCK63E is its 3‑step automatic gearbox with an external 3‑gear layout, offering three discrete speed ranges: low gear (30–150 rpm for high‑torque roughing on large diameters), medium gear (100–450 rpm for general turning), and high gear (400–1500 rpm for finishing operations). This multi‑speed transmission system, combined with the drive ratio options of 1:1, 1:4, and 1:11, allows the operator to optimize torque and speed for different workpiece materials and diameters.

The spindle is driven by an 18.5 kW main motor (22 kW total power) and features an A2‑11 spindle nose with a 105 mm spindle bore and 103 mm bar capacity – large enough to accommodate medium‑diameter bar stock for shaft and pipe components. The spindle is supported by high‑precision bearings, assembled in a temperature‑controlled environment to ensure high‑speed performance and long‑term reliability.

12‑station servo turret and hydraulic tailstock

The TCK63E is equipped with a 12‑station servo turret, providing rapid tool indexing and reliable tool clamping. The turret accepts tool shanks up to 32×32 mm (square) or up to Ø40 mm (round), accommodating a wide range of turning, grooving, threading, and boring tools. The servo‑driven design ensures consistent indexing accuracy and reduces tool‑to‑tool change time.

The hydraulic tailstock features a 100 mm diameter sleeve with a 120 mm stroke, utilizing a Morse No. 5 taper for center support. The hydraulic actuation allows the operator to engage and disengage tailstock support without leaving the control station, reducing setup time for shaft‑type workpieces.

Generous work envelope and load capacity

The TCK63E offers a maximum swing over the bed of 650 mm, a maximum swing over the cross slide of 470 mm, and a maximum turning diameter of 630 mm for disc‑type parts. The maximum turning length is 1000 mm, with a center distance of 1320 mm. The X‑axis travel is 325 mm, and the Z‑axis travel is 1100 mm. Rapid traverse speeds are 10 m/min on both axes, with X/Z axis servo motor torque rated at 18 N·m to maintain consistent feed force even under variable cutting loads.

The machine has a net weight of approximately 6,100 kg. This substantial mass contributes to vibration damping and overall cutting stability, making the TCK63E suitable for both roughing and finishing operations on steel, stainless steel, cast iron, and alloy components.

Accuracy and surface finish

The TCK63E delivers machining accuracy within IT6–IT7 grade. Roundness can be held within 0.005 mm, and surface finishes down to Ra 1.6 µm are achievable with appropriate tooling and cutting parameters. The minimum setting unit is 0.001 mm, providing fine control for precision operations.

Practical features for daily operation

• Automatic lubrication: Centralized lubrication system delivers timed, metered oil to all guideways and ball screws. An alarm signals when lubrication levels are low or system pressure is compromised.

• Chip management: The 45° bed slope directs chips directly into the chip tray. An optional chip conveyor (chain‑type) can be added for automated chip removal.

• Coolant system: High‑flow external coolant system with filtration keeps cutting temperatures under control and extends tool life.

• Full enclosure: The machine is equipped with a fully enclosed splash guard with safety glass windows, containing coolant mist and flying chips while providing good visibility of the cutting area.

CNC control options

The TCK63E can be equipped with a range of CNC control systems depending on customer preference, including Siemens, Fanuc, GSK, and other popular platforms. The control provides X/Z two‑axis simultaneous interpolation, constant surface speed control that automatically adjusts spindle speed as the tool moves across the part diameter, and thread cutting cycles for both straight and tapered threads. Multiple operation modes – Auto for production runs, Jog for setup, Handwheel for fine positioning, and MDI for single commands – give operators flexibility while maintaining accuracy.
