China Manufacturer Durable Mini CNC Lathe Qk1319 Big CNC Lathe Machine

Product Description1. The bed is one-piece ceiling-floor structure; The bed guide rails,wider than before, are treated with high-frequency quenching and precision milling to enhance its rigidity and thus assure its accuracy and service life. The moving surface of the guide rails is affixed with SD composite soft band and scraped to enhance is accuracy in orientation and durability.2. For the head stock, the gears are quenched at high frequency and milled, and with the built-in main motor, it is compact and use small space, delivering high efficiency in transmission. The main spindle is provided with two levels of variable frequency governing within the stock, easier to be operated. The larger range of governing not only allows processing working pieces with large torque but also enable cutting efficiently.3. For the cooling and lubrication within the stock in the front of the bed, the forced external circulation system is provided to lubricate and keep clean inside while ensuring effective temperature drop.4. The ball screw is driven directly by the motor and designed with a pre-stress tension mechanism, resulting in high accuracy in transmission.

Why choose us ?
1-The product adopts the advanced electric furnace melting
resin sand molding casting technology, so the gas permeability
is superior and it can effectively avoid the casting internal voids,
porosity.
2-With the super audio quenching treatment, the hardness
of Body guide rail can reach HRC55 degrees and above.
It can keep the hardness high accurate, and prolong the
wear resistance and service life.
3-The lathe bed adopts special structure ,and the natural
aging treatment, these all can greatly increased the rigidity
and are helpful to widen and thicken the dragging plate,
therefore the machine will be more stable and have the
stronger cutting ability.
4-The large plate guide rail (X rail) is also adopt the super
audio quenching treatment, so it increased hardness
and then could guarantee the service life of equipment
more efficiently. This is our particular advantage.
5-In order to make sure the accuracy, the equipment will
firstly tested by the laser interferometer imported from
Britain to test repeated positioning accuracy of X, Z direction.
Then the whole machine will be tested according to the
National standard.
6-Our enterprise has got the ISO9001-2008 quality system
certification and the European Union CE certification.
7-Our enterprise has got the recognition of the
high-quality product and a considerable market share
in both domestic and abroad.
