How much does the HNK HCT-52T cost?
Price estimate
We do not have a price for the HNK HCT-52T that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The HNK HCT-52T is barely larger in diameter than the size below it, yet its drive is a class larger. This crankthrow vertical lathe has a 5,200 mm (204.7 in) table, 5,600 mm (220.5 in) of swing, a 171 kW (229.3 hp) table motor and a load rating of 90,000 kg (198,413 lb).
So the HCT-52T is best read as the heavy-duty version of the five-metre machine. Its tool arm X travel, 2,550 mm (100.4 in), is identical to the HCT-50T. Z is 1,450 mm (57.1 in). Table speed is 1 ~ 35 rpm.
For a crankshaft maker the question is forging weight, not diameter. A throw for a large-bore engine can be compact and still very heavy, and an off-centre mass of that size needs torque to start, to hold speed through an interrupted cut and to stop. Control is Fanuc 31i-B, with Siemens 840D in braces.

Strengths & Limitations
Strengths
- 171 kW (229.3 hp) table motor
- 90,000 kg (198,413 lb) table load on a 5,200 mm (204.7 in) table
- Keeps the 1 ~ 35 rpm speed range of the smaller sizes
Limitations
- X travel of 2,550 mm (100.4 in) is no greater than on the HCT-50T
- Swing of 5,600 mm (220.5 in) is below the 6,000 mm (236.2 in) of the HCT-55T
- No tool arm, ram or tooling data in the table
