CNC Lathe Machines with 70mm Bar Capacity

These CNC lathes support bar capacities ranging from 4.53 inches (approximately 115mm) on the FEMCO HL-55 NT up to 24.02 inches on the Clausing CNC Lathe and FEMCO HL-55/1250, making them suitable for large-diameter oil field, marine, and heavy manufacturing workpieces well beyond the 70mm category minimum.

Most models come standard with FANUC CNC controls — including the FANUC Oi series. The Clausing CNC Lathe also offers optional Siemens CNC control for the SC series. Both control platforms provide reliable, industry-proven programming environments suitable for high-volume precision turning operations.

Yes. Both FEMCO and Clausing models are specifically designed and listed for oil field, oil country, and marine industry applications. Their large swing capacities, heavy-duty box-way guideways, and high-torque spindle motors handle the oversized, heavy workpieces common in those sectors with precision and durability.

It depends on the model. The FEMCO HL-55 NT and Femco CNC Lathe are chucker-style machines with no tailstock, designed for parts up to 24 inches in diameter without tailstock support. The Clausing CNC Lathe features a hydraulic tailstock with a rotating quill, programmable movement, and a 6 MT taper as standard.

Spindle power ranges from 35 HP on the FEMCO models (using a FANUC motor with a two-speed ZF gearbox) up to 75 HP on the Clausing CNC Lathe. The FEMCO HL-55/1250 supports configurations from 35 HP to 75 HP. Higher power options are ideal for heavy interrupted cuts and large-diameter roughing operations.

All machines are sold with delivery, installation, and operator training included. FEMCO models are delivered, installed, and warranted by T.R. Wigglesworth Machinery Co. The Clausing CNC Lathe adds a one-year warranty backed by Clausing's service center stocking over 80,000 parts, with 95% of orders shipped within 24 hours.
