BENCH CUTTING MACHINE
Document Type and Number:
Japanese Patent JP2016210004
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a bench cutting machine which can quickly stop a cutting tool while suppressing influence of reaction during braking.SOLUTION: A bench cutting machine comprises a base 1, a turn table 2 connected to the base 1, and further comprises a holder 5 installed upright and a cutting part 11, which is pivoted at an upper part of the holder 5 via a shaft 10, near a rear side end of the turn table 2. The cutting part 11 rotatably supports a circular saw blade 18. The cutting part 11 is provided with micro-switches 21, 23 near the shaft 10. When the cutting part 11 is positioned near a top dead point, the micro-switch 23 is switched on. When the cutting part 11 is positioned near a bottom dead point, the micro-switch 21 is switched on. In the case that the micro-switch 21 is switched on, a control part so sets a brake force as to be larger compared with the case that the cutting part 11 is positioned except for near the bottom dead point.SELECTED DRAWING: Figure 1
