• Higher productivity

  The LK-1903C achieves sewing speed of 2,700sti/min. The machine's starting, stopping, thread-trimming and automatic presser lifting speeds have been increased to significantly shorten total cycle time. This is a lockstitch button sewing machine that supports a variety of sewing patterns and cycle sewing.

• Standard LCD panel / Control box integrated with the machine head

  The control box integrated with the machine head, originally designed by JUKI, is adopted. The number of standard patterns is 50. As many as 999 patterns (500,000 stitches) can be stored in memory. The new upright type operation panel is installed on the side face of the machine head to allow the operator to operate the machine without averting his/her eyes, during sewing, from the bartack being sewn. In addition, the table surface can be used widely. The operation panel can also be installed on the table as before.
  ●If you want to install the operation panel on the table, an optional connecting cable (1.2 m) will be necessary. Part number: 40297363

  

  Two-way data communication function for sewing machine data using an NFC terminal (optional)

  The standard LCD panel is provided as standard with a USB port to facilitate data management between sewing machines and update of software. If you additionally use the optional NFC terminal, bidirectional data communication is enabled with a commercially-available Android terminal in a non-contact manner. This enables quick sharing of pre-set sewing data with other sewing machines to reduce the time required for set-up changing.
  ●Optional NFC terminal: Part number 40289481

  

• Bird’s nest preventing / Shorter-thread remaining specification (LK-1903CB)

  Users who are conscious about the finished quality of products manually nip, with scissors, the thread remaining on the material after thread trimming at the end of sewing. Now, the button sewing machine with the bird's nest preventing/shorter thread remaining functions saves such users the trouble of nipping the thread, thereby preventing the sewing product from being damaged by manual thread-nipping with scissors.

  The sewing machine eliminates so-called “bird’s nests” (thread tangling in on the wrong side of the material at the beginning of sewing).

  The thread is retained at the beginning of sewing and any excess thread is trimmed during sewing. As a result, the length of thread sewn in the seam is shortened, thereby achieving high-quality sewing
  performance while preventing thread from tangling in on the wrong side “of the material.”
  ●Use #60-80 (TEX22-30) polyester spun thread

  

  Length of thread remaining on the material at the end of sewing has been reduced to 2 mm or less*.

  The newly-developed shorter-thread remaining mechanism trims the thread shorter after the regular thread trimming operation. Additionally, thread waste produced by thread trimming is withdrawn by suction. Thanks to this mechanism, the trouble of manual thread nipping is avoided.
  * Remaining length of thread varies with sewing conditions

• The machine is provided as standard with the active tension (electronic thread tension control mechanism)

  ●Since the machine is provided with an active tension mechanism, it is able to set a needle thread tension that matches various sewing conditions (such as thread, material and sewing speed) on the operation panel, store the data in memory and reproduce it.
  ●The needle thread tension can be separated according to stitching type or portion of a seam, such as the beginning part of the seam, in the middle of sewing and end ofthe seam (fastening stitch).

  

• Excellent seam quality

  Needle thread grasping mechanism helps produce consistent knot tying at the beginning of sewing. (This device has been factory-set to “invoking prohibited” status at the time of delivery.)
  ●In the case “T” is selected for the work clamp foot/thread clamp

• Auto-lifter mechanism utilizing a system

  ●The machine is provided as standard with auto-lifter that uses a stepping-motor system. This helps reduce operator fatigue.
  ●It is also possible to change over the stroke of the auto-lifter from a onestep stroke to a double-step stroke, which offers easier positioning of a material on the machine. For the double-step stroke, an intermediate stopping height can be established on the operation panel.
  ●The work clamp foot lift can be set to a maximum of 13mm.

  

• The sewing starting point can be corrected

  The sewing starting point can be moved in the X and/or Y directions. The position of the sewing pattern can be corrected in accordance with the shape of the work clamp foot.

• Oil stains are eliminated

  ●Thanks to our advanced dry-head technology, the frame (needle bar and thread take-up) no longer requires lubrication. This prevents the material from being stained with lubricating oil.
  ●Just a small quantity of clean oil is supplied from the oil tank to the hook.

• Excellent workability and operability (Low-noise and low-vibration)

  ●The direct-drive head (with no belt), which is directly connected to a compact AC servomotor, achieves outstanding. This head helps create a comfortable working environment with reduced vibration and noise.
  ●The arm section of the machine head is fitted with a hand pulley. This allows the operator to visually check the needle entry points.

• Many different sewing patterns

  The machine is provided as standard with 100 different sewing patterns. The machine permits easy changeover of sewing patterns for effortless execution of an inexhaustible range of sewing specifications.

• Operator’s fatigue is reduced

  The LED hand light is now provided with color matching function using two colors (white/light bulb color) in addition to the conventional dimming function. Illumination is adjustable in five levels and dimming is in 10 levels to help reduce the eye fatigue of the operator who is engaged in sewing operation for extended hours.

  

• Noise and vibration are reduced

  This machine substantially reduces noise and vibration in comparison with the predecessor models to provide the wok environment that takes reduction of the operator's fatigue into consideration.
  ●Reduction of noise of the sewing machine by approximately 40%...... Stress on the ears is relieved
  ●Reduction of vibration of the sewing machine by approximately 7% ...... Working stability is improved

  

• Environmental-friendly power saving

  Aiming at the creation of environment-conscious products, an encoder is mounted on the stepping motor. Thanks to the JUKI’s unique control technology, power consumption of this machine is reduced by approximately 26% in comparison with the predecessor model.
