Semi-automatic lathe for dressing bamboo stumps utilized in furniture making

Abstract

A machine, similar to a wood lathe, was developed for semi-automatically converting difficult-to-clean bamboo butts with nodes, knots, and scars, into uniformly sized and clean poles of desired lengths and diameters. The technical performance and economic viability of the machine, called the MMSU bamboo pole dressing machine, were subsequently evaluated.

The main parts of the machine are an electronic-controlled cutter assembly, a three-speed transmission assembly and a three-point auto-switch-off. The cutter assembly enables the operator to adjust the scraper/cutter; the transmission assembly helps to select a desired spindle speed appropriate for scraping and sanding operations; and the auto-switch-off automatically shuts off the cutter assembly as the blade reaches the end of the pole.

The machine can process bamboo poles 59 cm to 250 cm long and 3.6 cm to 26 cm thick. Its processing speed is 4.2 cm min⁻¹. It takes 4.2 min (or 16.8% of the total processing time) to set and re-set a raw bamboo pole 90 cm long from an initial 7.6 cm to a final diameter of 7.0 cm, 18.6 min (74.8%) for scraping, and 2.0 min (8.4%) for sanding. The rate of return on investment is computed at 146%. The payback period is 6 months.
