Overview

The Makino UPN-01 is a compact, high-precision wire EDM built for micro-machining and ultra-fine feature cutting in the electronics, medical, and connector mold industries. This machine sits at the extreme precision end of Makino's wire EDM lineup, purpose-built for shops that need to cut features and tolerances that larger production wire EDMs simply cannot achieve.

Axis travel measures 200 x 130 x 100 mm (7.9 x 5.1 x 3.9 in) on X/Y/Z — deliberately small because this machine is engineered for micro-scale work, not production throughput. U and V axes provide +/-25 mm (+/-1.0 in) of independent wire guide offset for taper cutting on miniature components. The worktable accommodates workpieces up to 300 x 200 x 100 mm (11.8 x 7.9 x 3.9 in) with a maximum weight of 50 kg (110 lb).

The UPN-01 runs wire diameters from 0.02 to 0.20 mm (0.0008 to 0.008 in), including ultra-fine tungsten and molybdenum wires critical for micro-EDM applications. Surface finish capability reaches 0.05 um Ra (2 uin Ra) using Makino's proprietary multi-pass finishing technology with optimized spark parameters for fine wire. Positioning accuracy is rated at +/-0.001 mm (+/-0.00004 in) with repeatability of +/-0.0005 mm, backed by precision linear glass scales and a thermally stabilized machine structure.

The control is Makino's Hyper-i touchscreen interface with micro-machining-specific technology databases that simplify parameter selection for ultra-fine wire operations. The dielectric system uses temperature-controlled deionized water with precision filtration to maintain consistent flushing at the micro scale. Automatic wire threading handles even the finest wire diameters reliably.

The UPN-01 competes with the Sodick AP1L, Mitsubishi MP1200, and AgieCharmilles CUT 1000 in the micro wire EDM segment. New pricing typically runs $180,000 to $250,000 depending on configuration and wire handling options.

Strengths & Limitations

Strengths

Ultra-fine wire capability down to 0.02 mm enables micro-feature cutting that standard wire EDMs cannot touch
Sub-micron positioning accuracy (+/-0.001 mm) delivers the precision required for micro-mold and connector tooling
Surface finish capability to 0.05 um Ra eliminates secondary polishing on precision die components
Compact footprint fits into dedicated precision rooms without consuming excessive floor space
Hyper-i control with micro-machining databases simplifies parameter setup for ultra-fine wire operations
Temperature-controlled dielectric system maintains thermal stability critical for micro-scale accuracy

Limitations

Very limited travel envelope (200 x 130 mm) restricts the machine to small precision components only
50 kg workpiece capacity eliminates larger die and mold work entirely
Ultra-fine wire operations are inherently slow — this is not a throughput machine
Premium pricing relative to travel size makes it a tough sell unless micro-precision work is your core business

Best For

Connector mold shops cutting micro-pitch features below 0.1 mm that require ultra-fine wire Medical device tooling manufacturers producing micro-stamping dies for implant and surgical instrument components Semiconductor and electronics tooling shops cutting IC leadframe dies with sub-micron tolerance requirements Precision watch and instrument component manufacturers needing mirror-finish micro-features

Frequently Asked Questions

01 What does a Makino UPN-01 cost?

New UPN-01 machines typically price between $180,000 and $250,000 depending on configuration. The micro-precision platform commands a premium over larger U-series models despite the smaller travel. Used units are rare on the secondary market due to limited production volumes and the specialized nature of shops that buy them.

02 What wire diameters can the UPN-01 run?

The UPN-01 handles wire from 0.02 to 0.20 mm diameter. For micro-machining, tungsten and molybdenum wires in the 0.02-0.05 mm range deliver the finest features. Standard brass wire in 0.10-0.20 mm works for less demanding applications. The automatic wire threader is engineered to handle even the thinnest wire reliably.

03 How does the UPN-01 compare to the Sodick AP1L?

Both target the micro wire EDM segment. The Sodick AP1L offers linear motor drives for ultra-smooth axis motion and slightly larger travel. The UPN-01 counters with Makino's multi-pass finishing technology optimized for the finest surface finishes. Both achieve sub-micron accuracy. The choice often comes down to dealer support and existing machine brand preference in the shop.

04 Does the UPN-01 require a climate-controlled room?

Yes. To achieve the rated +/-0.001 mm accuracy and 0.05 um Ra finishes consistently, the UPN-01 needs temperature stability within +/-1 degree C and humidity below 60%. Most shops install micro wire EDMs in a dedicated temperature-controlled enclosure. Without environmental controls, thermal drift will degrade accuracy below the machine's capability.

05 What applications is the UPN-01 designed for?

The UPN-01 excels at micro-mold components, connector pin tooling, IC leadframe dies, medical micro-stamping dies, and watch components. Any application requiring features below 0.1 mm with mirror-finish surfaces and sub-micron positioning is the UPN-01's wheelhouse. It is not intended for general-purpose wire EDM production work.
