CNC Lathe Pre-Shipment Acceptance Checklist for Overseas Buyers

Check the bed surface condition, guideway protection covers, sheet-metal enclosure, door operation, cable and hydraulic routing, coolant tank and chip tray, and overall assembly cleanliness.

For a rigid lathe, ask the supplier to explain the bed structure. The TCK series uses a one-piece, ANSYS-optimised cast-iron 45° slant bed with a high-low guideway layout. Request clear photos of the machine base and guideway area.

The spindle should run smoothly across its range. The TCK series uses a built-in (direct-drive) electric spindle — on the A2-6 main spindle, rated to about 4,000–4,500 rpm with roughly 176 Nm of torque.

Request low-, medium- and high-speed runs within a safe testing range, plus noise and vibration observation, spindle direction and speed display confirmation, and a temperature check during a longer run. If you need high surface finish, check spindle stability carefully.

X and Z movement should be smooth, repeatable and quiet. Ask the supplier to test manual jog, programmed movement, reference return, limit switches, lubrication during movement, servo alarm status, and backlash or positioning if required.

The TCK axes use servo direct drive with pre-stretched ball screws to eliminate backlash. For precision production, request an accuracy report or sample-cutting proof.

If the machine has a servo or power turret, turret performance is critical. Check that all stations index correctly, the station number matches the controller, the turret locks firmly (the TCK turret uses a three-piece curvic coupling), indexing time is stable, there is no abnormal sound, and coolant and tool-holder clearance are correct.

For multi-operation parts, turret repeatability drives cycle-to-cycle stability.

The clamping system must match your workpiece and safety requirement. Check chuck open/close, hydraulic pressure display, leakage, tailstock movement, foot-pedal function, safety interlock, and air pressure if pneumatic functions are included.

Never accept a machine without confirming the clamping method suits your part and production plan.

Trial cutting is the most important part of acceptance — catalogue specs cannot replace a real machining test. Ask for a trial-cut video and inspection result using:

• ✓A material similar to your production material
• ✓A drawing or test piece agreed in advance
• ✓The required operations (turning, facing, boring, grooving, threading, and Y-axis milling/drilling if applicable)
• ✓Clear measurement after cutting
• ✓A surface-finish photo or video

For a critical part, send the drawing before machine production and agree on the standard. HORISTAR offers free sample testing on a representative part.

The TCK series is built to the GB/T16462-2007 precision standard. For high-precision work, define the acceptance tolerance, measuring tool and method before production starts.

Inspect the emergency stop, door interlock, chuck guard, electrical cabinet lock, warning labels, coolant splash protection, alarm display, and grounding/electrical safety.

Safety standards differ by country — confirm destination requirements before ordering.

Confirm: anti-rust oil applied, moving parts fixed, electrical cabinet protected, machine levelled and secured, export wooden-case condition, accessory box packed and listed, photos of the packed machine, and shipping marks.

Heavy machines need strong packing — request the net weight and crate dimensions so you can plan the foundation and container.
