Most vertical machining centers with a 1400 x 700 mm table give you about 1200 mm of X travel. The 1370 gives you 1300 mm, and it does it on a BT40 platform that weighs 9000 kg. That combination is the whole point of this machine: enough table and enough stroke to run two or three fixtures side by side, without paying for a BT50 heavyweight you don’t need.
Travel and table: what the numbers do at the machine
X, Y and Z travel are 1300, 700 and 750 mm. On a 1400 x 700 mm table that leaves genuine clamping room at both ends of the stroke. If you have run a machine where the table is long but the travel is short, you know how much time gets eaten moving clamps and re-zeroing. Here you can park one vise near each end, set up the second job while the first one cuts, and let the tool change stroke stay clear of the work.
Maximum worktable load is 800 kg, which is enough for a cast iron housing, a stack of plate work, or a heavy fixture with the part still bolted in it. T-slots are 5 x 18 x 130 mm, so standard M16 clamps and 18 mm slot tooling drop straight in.
Rapid traverse is 24 m/min on X and Y, 18 m/min on Z. That matters more than it looks on a machine with a long X. On short-cycle drilling and tapping patterns, the traverse rate and the acceleration behind it decide whether the air-cutting time adds up to minutes or seconds per part.
Spindle: BT40-150 at 8000 rpm
The spindle uses a BT40-150 taper running to 8000 rpm. That covers the usual mix: 10 mm to 20 mm carbide end mills in aluminum and mild steel, drills and taps, and light face milling where a 40-taper tool is already more than enough.
Standard configuration includes a 15 kW spindle motor, or an 11 kW low-speed high-torque motor if your work leans toward heavier cutting at lower rpm. The second option is worth asking about if you spend most of your time in steel rather than aluminum. Torque at low speed is what keeps a 50 mm face mill from bogging down, and the rated motor choice changes that far more than a spec sheet headline usually suggests.
Bed, ribs and guideways
The bed is built with “meter”-shaped reinforcement ribs. In practice that means the casting resists twisting under a heavy cut instead of letting the column and table deflect together. Rigidity shows up as surface finish and tool life long before it shows up in a positioning spec, so it is one of the few structural details worth asking a builder about directly.
The three-axis guide rail system uses 55-type rails. Wider rail sections spread the load over more bearing area, which is what lets the 1370 carry an 800 kg table load without the axes getting loose or noisy over time. It also gives the machine more tolerance for off-center cuts than a lighter rail size would.

Where it sits in the vertical lineup
BONANZA builds vertical machining centers from the VMC855 at 800 x 550 x 550 mm up to the L1690 at 1600 x 900 x 700 mm with a BT50-190 spindle at 6000 rpm. The 1370 is the step where the table gets wide enough for multi-part fixturing and the X stroke crosses 1300 mm, while the spindle stays BT40 at 8000 rpm.
That puts it in a useful place for shops that mostly run aluminum and steel parts in the 300 to 900 mm range and occasionally need to mount something bigger. If your parts are consistently over 1000 mm in Y, or you are cutting hardened tool steel all day, the BT50 machines in the series make more sense. If your parts are smaller and you care most about cycle time, the 855 is the cheaper answer.
For a direct comparison of table sizes, travels and spindle options across the range, see the vertical machining center series page. Horizontal work with a rotary table is a different conversation; that is covered on the horizontal machining center page.
Typical work for a 1370
Machines this size usually end up on:
- Die and mold plates, where long X travel and a 9000 kg base keep a 20 mm cutter stable through deep pockets
- Hydraulic manifolds and valve blocks, running drill and tap patterns across a long part in one setup
- Automotive fixtures and welding jigs, where the 1400 x 700 table takes a fabricated frame directly
- General plate and bracket work, two or three fixtures at a time
- Prototype and short-run parts that need the machine to change over quickly rather than cut at maximum metal removal rate
It is also a reasonable choice for shops adding a first large-format VMC, because the BT40 tooling you already own carries over.
What to confirm before you buy
Three things are worth settling in the quote. Motor choice, 15 kW standard or the 11 kW low-speed high-torque version, depending on whether your work is aluminum-heavy or steel-heavy. Whether you want through-spindle coolant and a chip conveyor, which change how the machine handles deep-hole drilling and long unattended runs. And the control and tool magazine configuration you need, since both vary by order.
Send your part drawings and the materials you cut, and you will get a configuration and a price that matches the work rather than a generic list. The factory is in Shandong, China and quotes direct. Request a quote for the 1370 or message the sales team on WhatsApp at +86 173 0632 8370.
