Overview

The Mazak QT-PRIMOS 150 is listed as a compact 6 in chuck lathe in Mazak's QT-PRIMOS series, a line Mazak builds around a built-in motor spindle, an 8 position drum turret and a small footprint. Mazak's model list for the series currently names one machine, the QT-PRIMOS 100 SG, and gives no separate table for the 150. The figures on this page are therefore the listed ones.

As listed, the spindle is 15 kW (20 hp) at up to 5,000 RPM on an A2-6 nose, with 52 mm (2.05 in) of bar capacity. Travels are 155 mm (6.10 in) in X and 310 mm (12.20 in) in Z, with rapids of 24 m/min in X and 30 m/min in Z, and the listed weight is 2,800 kg (6,173 lb). Short strokes and one turret make this a chucker for simple parts in volume, not a machine for long shafts.

Mazak describes the series turret as servo motor driven with non-lift indexing, and the listed index time is 0.2 seconds. Daily maintenance points are reached from the front and rear, with the lubrication oil tank at the front, so nothing has to be serviced from the left or right side. That is what allows the machines to be installed side by side.

The series is designed to be automated. Mazak offers a Quick Loader that fits in the same floor space as a standard machine, aimed at mass production of a small variety of parts, and a Gantry Loader for a larger variety, with a turn-over unit as an option and pallet stacking up to a height of 13.78". The control Mazak describes for the series is MAZATROL SmoothEz with a touch screen.

Strengths & Limitations

Strengths

8 position servo-driven drum turret with non-lift indexing; the listed index time is 0.2 seconds
Daily maintenance is done from the front and rear, so machines can stand side by side
Quick Loader automation fits in the same floor space as a standard machine, per Mazak
Listed 15 kW (20 hp) spindle at 5,000 RPM with 52 mm (2.05 in) of bar capacity

Limitations

Eight turret positions limit the tool count on parts with many operations
The listed table gives two different maximum diameters, 250 mm (9.84 in) and Φ7.09″, and two lengths, 280 mm (11.02 in) and 7.87″; confirm the real envelope with Mazak
Mazak's model list for the series shows only the QT-PRIMOS 100 SG, so whether a 150 can be ordered has to be confirmed
Listed travels of 155 mm (6.10 in) in X and 310 mm (12.20 in) in Z suit short chucked parts only

Best For

Short chucked parts in volume, loaded by Quick Loader or Gantry Loader Cells where machines stand side by side with front and rear access Bar work within the listed 52 mm (2.05 in) capacity

Frequently Asked Questions

01 Does Mazak currently list a QT-PRIMOS 150?

Mazak's model list for the QT-PRIMOS series names the QT-PRIMOS 100 SG and no 150. The figures on this page are listed figures for the 150, including a 6 in chuck, 15 kW (20 hp) and 5,000 RPM. Ask Mazak whether the 150 is offered in your region and for its own specification sheet.

02 What automation does Mazak offer for the QT-PRIMOS series?

Two systems. The Quick Loader automates loading and unloading in the same floor space as a standard machine and is aimed at mass production of a small variety of products. The Gantry Loader is aimed at a large variety of products, can take a turn-over unit as an option, and stacks material and finished workpieces on the pallet up to a height of 13.78".

03 What are the listed spindle and turret figures?

The spindle is listed at 15 kW (20 hp) and 5,000 RPM on an A2-6 nose with 52 mm (2.05 in) of bar capacity. The turret is an 8-position drum with a listed index time of 0.2 seconds. Mazak describes the series spindle as a built-in motor type and the turret as servo motor driven with non-lift indexing.

04 How much access does the machine need around it?

Mazak states that the areas for daily maintenance are accessible from the front and rear, that no maintenance is required on the left or right sides, and that the lubrication oil tank is at the front. Machines can therefore be placed side by side. Machine dimensions vary with specification, so get the layout drawing for the configuration quoted.
