Attention
Limit switch is the hardware sensor equipped on limit position of the two ends of each shaft. After detecting
limit triggering signal, the movement shaft will perform emergency stop to avoid "overreaching". Minimum one
limit switch is needed for each shaft to indicate limit position of the current shaft. The installation position of limit
switch may differ due to different types of machine, so the triggering signal. Therefore, configuration is needed.
Zero point of the machine is a referential point of a certain hardware fixed in processing breadth. Generally,
after power-on, "reset" is needed for the machine to create coordinate of lathe. The Epsilon-type cutter belt
series machines produced from our company generally take the limit switch position of each movement shaft as
the zero point of the machine.
Attention
3.3.2.3 Straightness and perpendicularity
Before starting formal processing，testing of movement straightness of each movement shaft and
perpendicularity of X-axis and Y-axis are needed. The straightness ensures movement accuracy and stability of
movement for this shaft. The testing shaft can be controlled to move along a straight line. If the straight line is
measure unstraight, it means twittering exists during movement of the shaft, and a solution is required. Reasons
for straightness of single shaft frequently lie in transmission of the motor or mechanical movement and machine
vibration.
CMA1309-B-A series machines is a rectangular Cartesian coordinate system. Theoretically, X-axis and Y-axis
should ensure be in absolute uprightness to ensure processing accuracy. If case of large tolerance for the
straightness, distortion of the processed figure will be caused. Method of measuring the straightness is to have
the control equipment go a rectangle frame on the surface of processing, and measure if the length of four sides
and diagonal are the same. Method of adjusting perpendicularity is to make adjustment of assembly of X-axis and
Y-axis movement mechanism.
Attention

Due to the less difference caused during production and assembly of the equipment, the
actual strike of each shaft on the same type of machine may be with a small difference.
Stroke setting is subject to the actual stroke.
At ex-factory, configuration of parameters for stroke, limit and reset has been already
performed. Unauthorized change of parameters by user before making clear its
meaning is prohibited. Otherwise, failure of the equipment may possibly be caused.
Debugging of straightness of perpendicularity of each shaft has been already performed
at ex-factory of the equipment. In case of problems found by users, please timely
contact our customer service personnel for a solution. Unauthorized disassembly of the
machine is prohibited.。
