SHINRI: size the loaded fixture, then choose the holder route.

A longer housing needs reach and withdrawal space

For plates, discs and small housings, compare V45 around the fixture and the highest clamped section. For a larger housing or long datum relationship, V70 adds X/Y/Z travel and a larger table. Include clamps, tooling and the part’s loaded orientation; a nominal part size is not the complete setup.

Ask which technical revision the offered spindle follows

The web V45 row lists 8000 / 18,000 / 24,000 rpm together, without a complete configuration mapping. The June 2020 sample describes an 8000 rpm BT40 reference. Do not assign the sample’s torque to all three speeds. For V70, the web table says 7000 rpm while the sample says 8000 rpm BT50. Confirm one quoted spindle, drive, holder interface and dated technical sheet.

V45 sample duty

52.5 Nm continuous / 96 Nm for 15 minutes; motor power written 11/15 kW without a separate duty definition.

V70 sample duty

95 Nm continuous / 115 Nm for 15 minutes; motor power written 15/18.5 kW without a separate duty definition.

What the cut requires

Request a speed/torque curve and allowable duty for the actual tool, engagement and material. A short-duration torque reference cannot be used as a sustained roughing rating.

V45’s web baseline rapid is 24/24/20 m/min with 36/36/30 listed as an option; the sample uses 36/36/30. V70 gives 24/24/18 in both. Neither rapid traverse nor maximum feed establishes complete cycle time, acceleration through short paths or achieved finish. State the selected build when comparing quotations.

Count assembled tools after reserving empty neighbours

Swipe the comparison sideways on a phone.

Large face mills consume neighbouring positions. Count roughing, boring, drilling, tapping, finishing, measuring assemblies and sister tools using the complete holder/tool mass and projection. Specify compatible retention hardware and balance limits for the selected speed. The common “24 tools” headline does not mean 24 largest-diameter assemblies fit at once.

The 1.8 and 2.5 second figures describe tool-to-tool changes. Include withdrawal, approach, spindle settling, chips, inspection and loading before comparing part cycles. The sample lists FANUC 0i-MF; confirm the current quoted control, options, CAM/postprocessor and recovery procedure rather than treating an old brochure as today’s complete bill of materials.

Use one demanding feature to test each setup

1. V45: close hole relationships

   Trial the deepest hole or smallest tap with the actual material and fixture. Inspect the datum relationship, thread gauge, burrs and tool wear. Include chip clearing and repeat loading in the measured cycle.

2. V70: reach and interrupted load

   Include the pocket, shoulder or bore requiring the longest projection and the distant feature that challenges fixture stiffness. Inspect size, form and finish after release where clamping distortion matters. Record thermal conditions and full cutting duty.

3. Machine record versus part result

   Agree serial-number geometry/positioning records separately from finished-part tolerances. Define datums, instruments, sample size, warm-up and acceptance conditions. A manufacturer’s generic positioning figure is not a guarantee for every housing or mould.

The sample’s installation footprint includes a chip conveyor: V45 3610 × 2100 × 2500 mm, V70 5040 × 3000 × 3150 mm. The web body dimensions differ. Obtain the complete delivered layout, door and maintenance movement, foundation and lifting plan; do not design a bay around the smaller body figure alone.

The brand group and the supplying legal entity are different questions

The official Changzhou company page identifies 江苏新瑞重工科技有限公司 under New United Group and describes SHINRI, Great Wall and Duoling brand families, with Changzhou and Yinchuan manufacturing activity. Its separate Ningxia page describes the Changcheng business and its earlier factory lineage. This does not assign every V-series machine to the same entity or site.

A 5 February 2026 Wujin environmental-project notice names the exact Changzhou company as premises lessor at Fengqi Road 20. That is a dated entity/site reference, not V45/V70 certification or an audited production-capacity claim. Confirm contracting company, manufacturing location, serial plate and the party responsible for commissioning and warranty.

The manufacturer describes installation, remote diagnosis, training and parts support; its attendance window varies by service region, and training scope depends on the contract. For an overseas installation, agree destination coverage, labour/travel charges, spare lead times, backups and escalation. Domestic hotline statements do not establish overseas arrival time or free relocation.
