Machine list

Based on our equipment list: the maker, number of units and diameter range of every model, by group.

Group 1: precision machining

NC lathes, and a vertical lathe up to φ600.

At its core are Yamazaki Mazak’s QUICK TURN series NC lathes. The MEGA TURN 600 vertical NC lathe is listed at φ100–φ600, so large-diameter parts fall within this group. The VTC 200 machining center also belongs to this group.

Diameter: φ10–φ600 (listed)
Types: NC lathes, vertical NC lathe, machining center

*1 The VTC 200 is a machining center, so its work size (10–900 mm) is listed instead of a diameter.

Group 2: automated mass production

Unmanned machining on robot-loaded lathes.

This group is built around robot-loaded NC and CNC lathes, with Takamatsu machines (including two-spindle models) and FUJI CNC automatic lathes. Our gantry-robot NC lathes run unmanned.

Diameters for the QT-PRIMOS100 SG and FUJI FS4-31 are values we have confirmed ourselves. “Mazak” in our equipment list is given here as Yamazaki Mazak.

Group 3: volume production (roots of manufacturing)

Thrust washers in volume, on single-purpose lathes.

Built around 24 loader-line machines (4 large-, 8 medium- and 12 small-diameter), with conventional lathes, a drill press, Gardner machines, a centerless grinder and band saws. Thrust washers are mass-produced on the single-purpose lathes.

Diameter: φ24–φ78 (loader lines)
Types: Single-purpose lathes (loader lines), conventional lathes and others

Lot size and diameter decide the group.

How we choose

This table is a guide to which group handles which lot size and diameter. The diameter breaks are listed values; the lot positions are approximate, based on the group names and process descriptions.

Lot size decided case by casePrecision machining group	G1Precision machiningφ5–φ210The lot sizes it takes are decided case by case, based on machine availability.		—Taken as prototypes and one-offs

Large diameters of φ210–φ600 are taken as prototypes and one-offs, not as volume production. Outer diameters over φ600 are handled by our group companies (ask us).

The diameter breaks (φ10, φ24, φ78, φ120, φ210) are diameters listed in our equipment list. G1–G3 stand for Group 1–3. φ5–φ10 is handled by the NC lathes (G1) and automated mass production (G2). Whether a job counts as volume production or prototype work depends on how often it repeats and on your requirements. Outer diameters over φ600 are handled by our group companies (ask us).

Over φ210

Outer diameter over φ210

Taken by Group 1 as prototypes and one-offs, not as volume production: QUICK TURN 200-2 (φ10–φ240), QUICK TURN 300 (φ20–φ300) and the MEGA TURN 600 vertical NC lathe (φ100–φ600). Outer diameters over φ600 are handled by our group companies (ask us).

Unmanned

Volume production, unmanned

Group 2 is built around robot-loaded NC and CNC lathes. Our gantry-robot NC lathes run unmanned.

Thrust washers

Volume production of thrust washers

Mass-produced on the single-purpose lathes of Group 3. The loader lines cover φ24–φ78 (listed values for the small-, medium- and large-diameter lines).

Secondary processes

Gardner, centerless grinding, cutting

The Nippei Gardner (up to φ120) and Omiya centerless grinder (up to φ100) work alongside the loader lines on Group 3 volume production. Steel cutting on the AMADA HA250 band saw is also part of the process.
