How much does the Makino V22 Graphite cost?
Estimated price range
Our best estimate for a vertical machining centers (vmc) in this class — not a quote from Makino. Configuration moves it a long way.
Overview
The Makino V22 Graphite is a small vertical machining center built around a 40,000 RPM HSK-E32 spindle, with 350 x 300 x 250 mm (13.8 x 11.8 x 9.8 in) of X, Y and Z travel over a 450 x 300 mm (17.7 x 11.8 in) table. It is not in Makino's current lineup and is probably an older model, so most buyers will meet it second-hand. The figures on this page are the listed ones and have not been matched to a current Makino page.
Everything in the table points at small electrodes and fine detail. The spindle is rated 3.7 kW (5 hp), the largest tool allowed is 1.26 in across and 1.1 lbs in weight, and the table carries 100 kg (220 lb). That rules out heavy roughing in steel; the machine is meant to spin small ball and flat end mills fast through graphite.
Graphite dust is fine, abrasive and conductive, which is why the machine is listed with an integrated sealed enclosure and a negative-pressure system to draw it out of the work zone. The axes run on precision linear guides at 787 in/min rapid and up to 394 in/min cutting feed.
The standard magazine holds 30 tools, with 60 given as the larger option. Chip-to-chip time is 8 sec, slow for production milling but of little weight on electrode programs where one tool cuts for minutes. The control is the Makino Professional 6 (Pro 6), and the machine weighs about 4,500 kg (9,921 lb). For comparison, the current iQ300 has 400 x 350 x 200 mm (15.7 x 13.78 x 7.87 in) of travel, a 45,000 rpm HSK-E32 spindle and 40 tools.

Strengths & Limitations
Strengths
- 40,000 RPM spindle with an HSK-E32 taper, sized for the small cutters used on graphite electrodes
- Integrated sealed enclosure with a negative-pressure system to keep graphite dust out of the machine
- 30-tool magazine as standard, with a 60-tool magazine listed as the larger option
- Compact 350 x 300 x 250 mm (13.8 x 11.8 x 9.8 in) envelope on a 450 x 300 mm (17.7 x 11.8 in) table and about 4,500 kg (9,921 lb) of machine
Limitations
- Spindle rated only 3.7 kW (5 hp) and tools limited to 1.26 in across and 1.1 lbs, so it is no roughing machine for steel
- Table load of 100 kg (220 lb) leaves little room for heavy vises, sub-plates or large blanks
- Chip-to-chip time of 8 sec slows jobs with many short tool changes
- Not in Makino's current lineup and the listed figures are unconfirmed, so check the machine itself before buying

Frequently Asked Questions
01
It is not in Makino's current lineup and appears to be an older model, so it is bought used. Before buying, check spindle hours, that the sealed enclosure and negative-pressure extraction are complete and working, and that the control is the listed Makino Professional 6 (Pro 6).
02
HSK-E32 tools up to 1.26 in in diameter and 1.1 lbs in weight, according to the listed table. The standard magazine holds 30, and 60 is given as the larger option. With 3.7 kW (5 hp) at up to 40,000 RPM, the machine suits small end mills and ball cutters rather than face mills or large drills.
03
The table is 450 x 300 mm (17.7 x 11.8 in) and takes up to 100 kg (220 lb). Travels are 350 mm (13.8 in) in X, 300 mm (11.8 in) in Y and 250 mm (9.8 in) in Z. X travel is shorter than the table, so lay out electrodes within the travels rather than to the table edge.
04
Cutting graphite makes fine, abrasive and conductive dust that wears guideways and gets into electrics. The V22 Graphite is listed with an integrated sealed enclosure and a negative-pressure system that pulls the dust out of the work zone. On a used machine, confirm the extraction unit came with it.
