Overview

The Citizen Miyano LZ-01 is an autoloaded precision CNC lathe designed for high-accuracy, high-throughput machining of small chucked parts up to 70mm diameter. The LZ series combines Miyano fixed-headstock precision with an integrated autoloading system for semi-unattended production without manual loading.

The LZ-01 features a 12-station turret with up to 6 driven tool positions for milling and cross-drilling alongside turning. The main spindle reaches 6,000 RPM with 7.5/5.5 kW power. The 6-inch hydraulic chuck provides secure, repeatable clamping.

The integrated autoloader loads individual workpieces (blanks, forgings, or pre-machined parts), processes them, and unloads finished parts. This architecture suits parts that cannot be produced from bar stock due to size, shape, or material constraints.

Miyano construction applies throughout: thermally symmetric cast iron base, precision-ground slideways, delivering dimensional stability across long production runs without operator intervention.

The LZ-01 excels at high-volume precision chucked parts: bearing races, valve seats, gear blanks, and components where autoloading eliminates operator-dependent throughput limitations.

Frequently Asked Questions

01 What does a Citizen Miyano LZ-01 cost?

A new Citizen Miyano LZ-01 typically costs between $45,000 and $65,000. Its specialized nature and limited production volume mean it holds value well on the used market, with machines from 2015-2020 fetching $25,000-$40,000.

02 What accuracy can the LZ-01 achieve?

The LZ-01 achieves positioning accuracy of ±2 microns and repeatability of ±0.5 microns. Turning roundness on stable materials is typically within 1 micron. These specifications make it suitable for the most demanding micro-turning applications.

03 Can the LZ-01 machine hardened materials?

The LZ-01 can machine pre-hardened materials up to approximately 40 HRC with CBN or ceramic inserts, but the low spindle power limits this to very light finishing cuts. For hard turning of larger features, a more powerful machine is recommended.

04 How does the LZ-01 compare to a collet-type micro lathe?

The LZ-01 offers better rigidity and thermal stability than most collet-type micro lathes, with a more capable CNC control system. Collet-type machines may be more economical for very simple parts, but the LZ-01's turret and CNC capability provide greater versatility for multi-feature miniature parts.

05 Is the LZ-01 suitable for production volumes?

Yes, the LZ-01 is designed for production use despite its small size. The reliable Mitsubishi control, quick turret indexing, and thermal stability enable consistent quality across production runs. Adding a compact bar feeder or parts loader enables semi-unattended operation.
