TH-85 Drilling and Milling Centre

Two build points matter most on this machine: ht300 cast iron is used: low melting point, small solidification shrinkage, compressive strength and hardness close to carbon steel, and good vibration resistance; and annealing and natural ageing eliminate internal stress in the castings, so they stay stable and do not deform over the long term. Structure decides how a machine ages — the specification table tells you what it does new, the build tells you what it does in year five.

The catalogued work list for the TH-85 covers new energy, automation, 5g communications, consumer electronics. If your part sits outside that list it is not necessarily wrong for the machine — send the drawing, the material and the tolerance and we will place it honestly, on this machine or another.

The TH-85 runs X 500 / 500 / 700 / 800 mm, Y 400 / 400 / 400 / 500 mm, Z 350 / 300 / 350 / 450 mm. Check the envelope with the longest tool at the part’s tallest point — Z is the axis that runs out first on most jobs — and keep 20–30 % margin over your largest recurring part rather than sizing to a one-off.

Both sit in the drilling and milling centre group, so the decision is capacity and duty, not kind: put your largest part dimensions, material and yearly quantity against each specification table and one of the two will run out of a figure first. Send the drawing and we will name which of the two fits — including the case where the smaller machine does the job.

Every TH-85 is laser-measured to ISO 230-2 over its travels, cuts a test piece that is measured rather than admired, and ships with a serial-numbered report carrying the measured values. If any line misses, the machine goes back into the shop until it passes — the report is a record, not a promise.
