Toshiba BTD-110H.R16

Selling a used Toshiba BTD-110H.R16

Shibaura's English catalog prints the R13 and the R16 in one specification table, so check the plate for which of the two you have. The R16 column shows a table of 1,400 x 1,600 mm with nine T-slots; the R13 table is smaller, with seven. For the R16 alone the catalog adds a wide stroke option, X to 2,500 mm (98.4 in) and Y to 1,800 mm (70.9 in), and an outside auxiliary slideway on Z. Measure both travels before you describe it.

The spindle came in more than one build. The standard type spans 5 min-1 up to 3,000 min-1, and the catalog gives it an AC 15/11 kW motor, with high power motors of AC 22/18.5 kW and AC 30/22 kW as options. A high speed type covers 40 through 8,000 min-1 from a special built-in motor rated AC 26.5/22 kW and uses a 200 mm quill with a 400 mm W stroke. Copy the motor plate and the top speed shown on the control into your notes.

Shibaura's current English spec page for the Americas lists a Big Plus spindle with through-spindle coolant as standard, and a high-speed head of AC 40/30 HP at 15 to 5,000 rpm; a 2020 copy of the same page gave that head as AC 35/30 HP at 40 to 8,000 rpm instead. Its pallet changer option is a two pallet unit, 4,500 kg (9,900 lbs) on each pallet. If a high-speed head or pallets came with this mill, record which, and the fixtures on each pallet.

Several heads on the option list are separate pieces that can leave with the machine or stay behind: an angle head with a JIS 7/24 taper No.50 hole, rotating facing head C (600 mm outer diameter, 150 mm tool slide travel) and rotating facing head CS (430 mm and 80 mm), which the catalog says can bore spherical surfaces. Holders for both facing heads were listed too, among them a telescopic one for head C. Photograph each head with its holders and state which ones go with the mill.

Probing on this model was an option, and its parts belong together. The catalog lists an automatic measuring function with a dedicated FM type touch probe, a calibration block for it, automatic tool length measuring with its own reference tool, a test bar and a table reference piece. B-axis setup compensation, which measures how a part sits on the table and then indexes it square to X, needs the measuring option. Keep the probe, block and reference tool together and name them.

Only one coolant set can be selected, the catalog notes. The flood set pairs a lift-up chip conveyor with a 330 liter tank, the through-tool set adds a 1.2 MPa (170 psi) pump, the coolant and air blow set needs a 15 kW (20 HP) compressor, and the through-spindle set changes the spindle head unit itself. Find out which one this R16 carries before you write it up, because it decides which holders and drills a buyer can run.

Each size was also built with a pallet changer, and Shibaura's main table shows what the pallet version gives up in table load. The R16 holds 6,300 kg (13,860 lbs) on its plain table and 4,500 kg (9,900 lbs) with APC; the R13 goes from 4,000 kg (8,800 lbs) to 3,000 kg (6,600 lbs). The R16 weighs 28,000 kg (61,600 lbs), or 33,000 kg (72,600 lbs) with APC, against 22,000 kg and 26,500 kg for the R13. Give the weight of the exact version, because a buyer sizes the foundation from it.

Travel sets the two sizes apart as much as the table does. Shibaura lists X, Y and Z travel as 1,600, 1,250 and 1,130 mm on the R13, and 2,000 mm (78.7 in), 1,500 mm (59.1 in) and 1,450 mm (57.1 in) on the R16, each with 500 mm (19.7 in) of W. A wide stroke R16 also rates its table at 10,000 kg (22,000 lbs), is 4,300 mm tall rather than 4,000 mm, and needs 5,730 x 6,560 mm of floor. If the plate is missing, read the stroke limits from the control's parameters.

The spindle itself is 110 mm (4.3 in) across inside a 225 mm (8.9 in) milling nose with a 7/24 No.50 taper hole, and the linear axes feed at anywhere between 1 and 6,000 mm/min (236.2 ipm). From the table center to the spindle gauge plane the R16 spans 550 to 2,000 mm, where the R13 spans 410 to 1,540 mm. Quote that span when a buyer asks how far a fixture can sit from the nose.

Shibaura closes the loop on X, Y, Z and B with 1 µm linear scales and a rotary scale, and prints these figures for both sizes: 0.005 mm roundness for boring, linear positioning to ±0.005 mm end to end of each stroke, and X, Y and Z repeat within ±0.003 mm. The table indexes to ±3 seconds at any angle and repeats to ±1.5 seconds, and the W extension is held to ±0.010 mm over its length, repeating to ±0.008 mm. Those numbers are taken with nothing on the table, so attach the latest laser or ballbar report to the listing.

For heat, Shibaura publishes a test on the standard BTD-110 spindle: seven hours of continuous running with no load at 1,000 min-1, in a temperature controlled room. Afterward the spindle had shifted 1 µm on X and 14 µm on Y, both in the minus direction, and 23 µm on Z. An oil jacket and a constant volume of lubricating air mist on the bearings are what the catalog credits for that. Warm the spindle for an hour before any test cut a buyer watches, with the mist unit filled and running.

Bed, saddle, column and spindle head are all castings, and Shibaura hardens and grinds the slideways. The bed uses a 4-way guideway layout, the saddle keeps the table's moves across and along straight and parallel, and the column's step-type guideways are 770 mm (30.3 in) wide to resist the cutting force moment. Draw the way covers back, photograph the exposed ways and the wipers at both ends, and note any scoring.

Shibaura's heavy cutting example for this machine faces S48C carbon steel with a 160 mm (6.3 in) face mill on 250 mm (9.8 in) of spindle extension, a length to diameter ratio of 3.5. At 120 m/min and 550 mm/min, or 0.38 mm a tooth, it takes a cut 120 mm across and 6 mm deep and removes 400 cm3 a minute. If the mill can be run, a face cut of that kind on scrap, with the chips and surface photographed, shows how the extended spindle holds up.

A second table in the catalog runs five operations on AISI 1055, a carbon steel. Face milling with a 160 mm cutter at 130 m/min and 870 mm/min removes 630 cm3/min; an 80 mm end mill cuts 50 x 20 mm at 540 mm/min; boring with a 600 mm (23.6 in) head at 100 m/min, the feed is 28 mm/min at 7 mm depth, for 355 cm3/min. A 69.5 mm (2.7 in) drill runs at 22 m/min and 60 mm/min, and taps from M3 to M100 run at 6 to 10 m/min. Ask the shop for the largest drill and tap it has put through this spindle.

Shibaura also prints a job timed on a BTD-110H.R16 against a conventional machine, a box part about 1,510 x 820 mm, with 16 tools used on each. Setup on the R16 took 24 minutes in 2 setups, against 48 minutes in 4 on an inclined stand, and its average per piece with setup came to 157 minutes (2.6 hrs) against 342. The R16 measured once, automatically, where the other machine measured three times. Present it as the maker's example, together with the part it describes.

NC rotary milling is an option on this mill: continuous indexing of the B table cuts cylindrical and end faces in one run, with no separate NC rotary table, and the cylindrical interpolation function lets an operator write a cylinder face program by hand at the control. The continuous table indexing device steps in 0.0001 degree. Run a short arc move on B in the demo if the option is fitted, so a buyer sees the table turn under feed.

The pendant box on this model keeps the hand controls away from the NC unit: a spindle lever with five settings, forward, reverse, stop and a jog each way, axis selectors pairing X with Z and Y with W, a B selector, a spindle lock at any angle and spindle centering rotation. At the TOSNUC 999 screen, customizing keys hold six key sequences and four screen layouts, and the display divides into three panes so two programs and the offsets can be edited side by side. Film each pendant control working during the demo.
