Citizen Cincom M32-VIII

The Citizen Cincom M32-VIII is the B-axis version of the M32, Citizen's 32 mm sliding-headstock lathe with a gang tool post and a 10-station turret. It keeps the series' 32 mm dia. bar capacity (38 mm dia. OP), 320 mm stroke per chucking and 8,000 rpm main and back spindles, and adds B-axis drills on the gang side. With 30 to 36 +α tools it has the largest tool count of the three variants Citizen lists.

The B-axis is the reason to choose it. Cross drills rise to 8, of which 4 are B-axis drills, and the gang tool post carries 4 backside drills that the table also counts as B-axis drills. Angled holes can then be drilled in the cycle instead of in a fixture afterwards. The Cincom M32-VII has 5 to 7 cross drills and no B-axis row; the Cincom M32-V has the same cross drills and only 5 back tool post drills.

At the back end the VIII matches the VII: max. 9 back tool post drills and a Y3 axis at 32 m/min. Back rotary tools run to 6,000 rpm on 1.0 kW, which limits them to 8 mm dia. drilling and M6 tapping, while the back spindle accepts a 32 mm dia. chuck (38 mm dia. OP) and handles 12 mm dia. and M12. The turret's rotary tools are the strongest on the machine for cross work, 12 mm dia. and M12 at 6,000 rpm and 2.2 kW, and gang rotary tools reach 9,000 rpm for 8 mm dia. and M8.

Both spindles are driven by 5.5/7.5 kW motors. Rapids are 32 m/min on the main linear axes, with X2 at 18 m/min and Y2 at 12 m/min.

The power requirement is listed at 25 kVA, against 24 kVA in the tables of the Cincom M32-V and Cincom M32-VII. Average power under load is 13.1 kVA, full-load current 79 A and the main breaker 100 A. Weight is 4,300 kg on a W2,860 × D1,465 × H1,900 mm footprint, and the pneumatic unit draws 110 NL/min at 0.5 MPa when stationary.
