JIER TK/TH69

TK/TH69 is a floor-type boring/milling and machining-centre series whose reviewed official page is dated 27 October 2020. It addresses large heavy housings with configurable heads, rotary tables and accessories. Draw the bore axis, floor or rotary fixture and required approach before selecting a boring-bar diameter or travel. Catalogue range extremes are not a single ready-made configuration.

Published boring-bar options are 160/200/260/320 mm, with spindle power 58–135 kW and maximum-speed range 1000–2000 rpm. W boring-bar travel options are 1200/1600/1800 mm and Z ram options 1200/1600/2000 mm. Keep W and Z separate and review tool/head projection at the deepest cut. The manufacturer describes hydrostatic guides/support and deflection/offset compensation, but these mechanisms do not prove a finished bore at every unsupported reach.

X travel is expressed as 6000 + n × 1000 mm and Y range as 3000–8000 mm. Rotary-table size is 2500 × 2500 to 5000 × 5000 mm, with listed load 30–160 tonnes. Obtain the selected table’s distribution, centre-of-gravity, overturning-moment, indexing/clamping and complete swept-envelope limits. The nominal load is not a crane specification, and the table’s area does not establish clearance for every corner of a rotated housing.

Plan foundation, anchoring, levelling, environment and loading access with the delivered layout. Trial the deepest bore at the quoted bar/ram extension and datum relation after indexing or re-clamping; inspect after release under agreed thermal and measurement conditions. Record cutting, transfer/indexing, measurement and restart separately. Confirm control and included fault/maintenance monitoring, serial test records, contract-based commissioning and destination spares/support; described software functions are not a safety certification.
