CNC Gantry drilling and milling machining center RD20 spindle BT50
CNC drilling machine
I.Machine features:
RD series of products for the disc parts of high efficiency, high
stability drilling requirements, in the structural rigidity and
drilling capacity and improve the precision of hole processing
position has been greatly optimized, making it a professional
optimization model focusing on industry applications.
1.1 Main structure
RD20 adopts the most stable gantry frame, the bed is arranged with
internal reinforcement, the bed structure is thick, the cross
section optimized beam is arranged with large span step guide rail,
the Z axis of the high strength saddle adopts six slide block
structure, so that the spindle box has high static and dynamic
rigidity. The machine is composed of the main key parts, the main
motion system, the feed motion system, the tool storage auxiliary
system, the pneumatic system, the lubrication system, the
protection system, the chip removal and cooling system, the
electrical control system and so on.
1.2 Main key parts
The bed body, worktable, column, saddle and headstock of RD20 are
made of HT300 high strength grey cast iron, which has good
rigidity, shock absorption and precision retention.
RD20 all key items are completed by our company CNC gantry
machining center, roughing and semi-finishing and imported by
Japan's new Japanese machine multi-function longmen pentahedron
machining center (HF - 5 m) in constant temperature workshop to
complete the final finishing process, to ensure that key large
machining precision, thus ensuring the geometric accuracy of
machine tools.
1.3 Main motion system
RD20 main motion system adopts spindle servo motor to drive through
belt, and the structure of driving mechanical spindle is as
follows:
The spindle unit is the core part of the machine tool. It adopts
high precision spindle unit, model: BT50. The main motion system
adopts spindle servo motor power of 15/18.5kW, maximum output speed
of 4000rpm, and output torque of 214/255N.m.
1.4 Feed movement system
RD20 has three linear feed shafts. The three-axis feed mechanism
adopts AC servo motor. The non-backlash elastic coupling is
directly connected with the lead screw to realize the reciprocating
movement of each shaft.
1.5 Protection system
The protective form of RD20 guide rail: X axis is 201 stainless
steel protective pull plate, Y axis is organ cover, Z axis is
stainless steel armor plate to provide adequate protection for the
feed system; The protection of the machine tool is designed and
manufactured by our company. The operation area of the machine tool
is fully enclosed to ensure the safety and protection performance
during operation.
1.6 Chip removal and cooling system
RD20 chip discharging adopts double stranded cage and after chain
chip discharging device, chip receiving car.
The cooling system adopts two cooling methods of tool internal
cooling and external cooling. The internal cooling adopts 20bar,
65L/min high-flow high-pressure center water filtration system, and
the external cooling adopts 67L/min flow rate and 27m head to
ensure the reliability of cooling.
Standard configuration of high-pressure water gun, can better clean
the machine tool iron filings.
1.7 Pneumatic system
RD20 adopts pneumatic control components with reliable performance
and good stability to change the tool for the spindle, clean air
blowing for the spindle center, and dry and clean compressed gas
for the external air gun.
