Driven-tool turning centres

A new range of CNC turning centres with live tooling in the turret has been introduced by Hurco. The three models – TM8Mi XP, TM10Mi XP and TM12Mi XP – cover the 8-, 10- and 12-inch chuck sizes required by most manufacturers.

Hurco previously sold a range of driven-tool lathe models designated TMM, but their performance was limited as they were not controlled by the proprietary Max5 control that has proved so popular on the company’s machining centres due to features such as concurrent programming and recovery restart.
The new lathe control system, an in-house development by Hurco’s software engineers, was first introduced on the XP-series of two-axis lathes in early 2018. This all-digital control platform was delivered alongside improvements to the design of the machine, including a smaller footprint, roller guideways in the linear axes, a larger spindle bore and enhanced rigid tapping.
A primary reason for developing the TM Mi XP range, in addition to adding the superior features of the Max5 control, was to ensure that driven-tool milling is smooth and accurate. The machines include a servo-controlled C axis and the capability to deploy driven tools at all turret positions, allowing milling and off-centre drilling to be performed in addition to normal turning operations.
Two machines are currently in the UK, a demonstration model at Hurco in High Wycombe and another on trial at a customer’s factory. The first machines available for sale will arrive later this month. These models will be the new 8-inch chuck version which, compared with the former TMM lathes, offer higher spindle power at 22.6 kW, a spindle bore increased from 62 to 79 mm, a draw tube diameter of 64.5 mm (up from 52 mm), and faster rapids at 30 m/min (previously 24 m/min).
