Overview

The Enshu SH350 is a compact horizontal machining center built around a No. 30 taper spindle, designed to reduce both installation space and capital investment for shops needing horizontal machining capability. With axis travels of 500 x 400 x 400 mm, a 650 x 400 mm work area, and a 300 kg table capacity, the SH350 targets production of small to medium aluminum and non-ferrous parts where horizontal chip evacuation and four-face access are critical.

The spindle runs at 12,000 RPM with a No. 30 (7/24) taper, delivering 5.5 kW for five-minute duty, 3.7 kW for ten-minute, and 1.5 kW continuous. This power profile is matched to high-speed drilling, tapping, and light milling operations on aluminum castings, electronics enclosures, and small automotive parts. The No. 30 taper keeps tooling compact and tool change times fast, which is essential in production environments where non-cutting time directly affects throughput.

The SH350 accommodates 16 tools standard with an optional 21-tool magazine, sufficient for the repetitive operations typical in small-part production runs. The machine occupies a 1,650 x 2,250 mm floor space at just 2,000 mm height and 3,500 kg weight, making it one of the most compact horizontal machining centers available. This size allows dense machine layouts with multiple SH350 units processing parts in parallel.

Enshu designed the SH350 to bring horizontal machining capability to shops and production cells where traditional horizontal machining centers are too large and expensive. The horizontal spindle orientation provides natural chip evacuation during drilling and boring operations, which is a significant advantage over vertical machines when machining components with deep holes and internal features that trap chips.

Strengths & Limitations

Strengths

Ultra-compact footprint of 1,650 x 2,250 mm is among the smallest horizontal machining centers available
12,000 RPM No. 30 spindle delivers high-speed drilling and tapping performance on aluminum and non-ferrous parts
Horizontal spindle orientation provides natural chip evacuation for parts with deep holes and internal features
Low machine weight of 3,500 kg requires no special foundation preparation
Entry-level pricing brings horizontal machining capability to shops that cannot justify larger HMC investments
Low 2,000 mm height allows installation in facilities with limited overhead clearance

Limitations

No. 30 taper severely limits cutting forces and tooling options for steel and cast iron machining
1.5 kW continuous spindle power restricts the machine to light cutting operations on non-ferrous materials
500 x 400 x 400 mm travels constrain the machine to small parts only
Enshu's dealer network outside Japan is limited, affecting service availability in many markets

Best For

Small automotive and electronics parts requiring horizontal machining with natural chip evacuation Production cells needing multiple compact horizontal machining centers in tight floor space Shops transitioning from vertical to horizontal machining for improved chip management on drilled and bored parts High-volume aluminum component production where compact, fast HMCs drive throughput Budget-conscious shops needing horizontal machining capability without the investment of full-size HMCs

Frequently Asked Questions

01 What does an Enshu SH350 cost?

New Enshu SH350 machines typically price between $150,000 and $250,000 depending on tool magazine capacity and automation options. This is significantly less than full-size BT40 and BT50 horizontal machining centers.

02 How does the SH350 compare to the GE460H?

The GE460H is a much larger machine with BT40 taper, 560 x 560 x 560 mm travels, 500 kg capacity, and 40 tools. The SH350 is a compact entry-level HMC with No. 30 taper and lighter cutting capability. The GE460H handles production-level ferrous and non-ferrous machining, while the SH350 is focused on small non-ferrous parts.

03 Can the SH350 machine steel?

The SH350 can machine mild steel with appropriate tooling and conservative parameters, but its No. 30 taper and 1.5 kW continuous power rating make it impractical for steel production work. The machine is designed for aluminum, brass, and other non-ferrous materials.

04 Why choose horizontal over vertical for small parts?

Horizontal spindle orientation provides gravity-assisted chip evacuation, which is critical when drilling and boring parts with deep holes and internal cavities. Chips fall away from the work zone instead of accumulating in pockets and bores, improving surface finish, tool life, and process reliability.
