Taikan T-500B

T-500B combines drilling, tapping and milling for compact plate, disc and housing work. The Chinese catalogue and machine mark use T-500B; the English product table uses HT-500B while its headings also use T-500B. Confirm the offered revision and name in the quotation. The reviewed travel is 500/400/320 mm, table 620 × 400 mm and listed load 250 kg; assess the complete loaded fixture and support distribution, not only the blank dimensions.

BT30 and the 180–500 mm nose-to-table window define a different setup from Taikan’s BBT40 vertical reference. The English table lists 20–24000 rpm, 3.7/5.5 kW and 14.1/21 Nm rated/short-time pairs. The Chinese application description also contains a 20000 rpm spindle description. Obtain the offered spindle curve, revision and short-time duration; do not promise maximum torque at maximum speed or suitability for a particular large/deep tap without the cutting trial.

The reviewed magazine entry is 21 tools with 3 kg maximum mass, 300 mm length and 60/80 mm diameter with adjacent tools present/empty. Chinese material describes larger magazine alternatives separately; do not add those to the reviewed build. Map holders and occupied pockets. The named control is Mitsubishi M80VA, rapid traverse 48 m/min per axis and cutting feed range 1–15000 mm/min. Test spindle reversal, thread inspection, chips and safe retracts in the actual sequence rather than deriving a cycle from rapid speed or the adjacent-tool-change claim.

Published positioning/repeatability is 0.006/0.004 mm with a full-travel GB/T 18400.4 reference; it is not the tolerance of a finished thread or housing. Trial the quoted fixture, programme, material and tools, inspect after unclamping and include worn/broken-tap recovery. Utility references are at least 200 L/min ANR air at 0.6–0.8 MPa, 15 kVA capacity and maximum 145 L coolant tank. Body dimensions are 1690 × 2660 × 2320 mm and approximate mass 3100 kg; request the full installation/maintenance layout and destination training/support scope.
