Overview

The Hydromat EPIC 45 is Hydromat's flagship CNC rotary transfer machining platform, representing a significant evolution from the foundational HT series. Where the HT machines use a primarily hydraulic-actuation architecture, the EPIC (Electronic Precision Integrated Control) series replaces hydraulic axis drives with CNC servo drives on every spindle unit and feed axis — delivering position feedback, programmable feed rates, and full closed-loop control at each of the machine's 16 stations. The 45 designation refers to the maximum 45 mm bar stock diameter capacity. This combination of 16-station simultaneous machining and full CNC servo control on every axis makes the EPIC 45 one of the most capable volume production machining platforms available for prismatic and rotational parts in the 45 mm diameter class.

The EPIC 45's 16-station rotary table provides twice the process complexity of the 8-station HT series, allowing more intricate parts with a greater number of distinct machining operations to be completed in a single cycle. Each station accepts Hydromat's modular tooling heads: horizontal and vertical drilling/boring units, tapping units, milling heads, thread whirling units, polygon turning units, and specialized form tool stations. The CNC servo drives allow each spindle's feed rate, depth, and dwell to be individually programmed, enabling features like peck drilling, chip-breaking cycles, and precision boring with in-feed compensation. Indexing is servo-hydraulic with electronic position verification at each station.

Hydromat's EPIC control platform — based on a Siemens 840D sl or equivalent industrial CNC — stores complete job programs including all station spindle speeds, feed rates, depths, and sequencing logic. Job changeovers on the EPIC 45 are accomplished primarily through program recall and tool offset adjustment rather than physical spindle reconfiguration, making the EPIC more flexible for mixed-production environments than the older HT series. For dedicated production of a single part family, however, the EPIC 45's cycle time advantage remains its primary value proposition: a 16-second cycle on 16 simultaneous stations produces the same output as 16 machining centers each running a 256-second cycle — at a fraction of the combined floor space and labor cost.

New EPIC 45 systems are priced in the $900,000 to $1,500,000 range, reflecting the substantially more sophisticated servo-CNC architecture versus the HT series. At this price level, the EPIC 45 is targeted at tier-one automotive suppliers, hydraulic and pneumatic OEM component manufacturers, and precision defense contractors with committed high-volume production programs. ROI analysis typically requires 100,000+ annual parts with consistent design to justify the investment, but for qualifying production programs the EPIC 45's throughput and quality advantages are compelling.

Strengths & Limitations

Strengths

  • 16-station simultaneous machining produces extraordinarily high throughput — cycle time equals only the slowest station, regardless of total operation count
  • Full CNC servo drives on every axis (the EPIC difference) enable peck drilling, programmable feed rates, precision boring with in-feed compensation, and closed-loop position control at each station
  • Program-based changeover reduces inter-job setup time compared to HT series — job programs store all station parameters for rapid recall
  • 45 mm maximum diameter accommodates a wider range of automotive and hydraulic components than the 32 mm HT-32
  • Proven Hydromat EPIC platform with extensive installed base in tier-one automotive and hydraulic component manufacturing

Limitations

  • Capital cost of $900,000–$1,500,000 demands very high production volumes and long product life cycles to justify — not appropriate for low-volume or highly variable production
  • 16-station configuration requires significant floor space (approximately 22 m²) and a dedicated foundation with vibration isolation
  • Maximum 45 mm diameter limits the machine to medium-sized components — larger parts require the HT-57 or specialized custom configurations

Frequently Asked Questions

01 What is the EPIC difference compared to the Hydromat HT series?

The HT series uses hydraulic actuation for spindle feed axes, with mechanical stops and cams controlling feed depth. The EPIC series replaces all hydraulic feed drives with CNC servo axes — each station's feed rate, depth, acceleration, and cycle are individually programmed and closed-loop controlled. This enables advanced cycles (peck drilling, chip breaking, precision boring with in-feed compensation) that hydraulic actuation cannot perform. The EPIC platform also provides better diagnostic capability and faster program-based changeover.

02 How many parts per hour can the EPIC 45 produce?

Throughput depends entirely on the application. For a typical automotive hydraulic valve body with 14 machining operations (drilling, reaming, tapping, milling) at a 15-second cycle time, the EPIC 45 produces 240 finished parts per hour. For simpler components with a 10-second cycle, output reaches 360 parts per hour. For complex parts requiring longer individual station cycles of 25-30 seconds, throughput is 120-144 parts per hour — still far exceeding what sequential CNC machining could achieve.

03 Can the EPIC 45 handle both aluminum and steel parts?

Yes. The EPIC 45 handles aluminum alloys (2024, 6061, 7075), brass, cast iron, mild steel, stainless steel (304, 316), and titanium alloys. Tool selection, spindle speeds, feed rates, and coolant strategy are configured per material. Aluminum is the most common material in EPIC 45 applications given its machinability and prevalence in automotive fluid power components. Steel applications typically require higher-torque spindle units and through-spindle coolant at higher pressures.

04 What changeover time should be expected when switching between part families?

The EPIC 45's servo architecture allows program-based changeover for parts that use the same tooling and fixturing layout — program recall plus tool offset verification typically takes 30-60 minutes. When switching between significantly different part families requiring different spindle modules or fixtures, full changeover can take 4-12 hours. For high-volume dedicated production programs, changeover frequency is low enough that this is rarely a limiting factor.

05 Is the Hydromat EPIC 45 still in production?

Hydromat continues to manufacture and support the EPIC 45 platform from their St. Louis, Missouri facility. The machine benefits from ongoing software updates to the EPIC CNC platform and can be retrofitted with current-generation spindle units as technology advances. Hydromat's service organization supports the full installed base of EPIC machines globally.
